The Certified Wireless Technician (CWT) certification is an essential entry-point for professionals starting their careers in wireless networking. The CWT-100 Exam is designed to validate the foundational knowledge required to install, configure, and troubleshoot Wi-Fi networks in the field. It serves as the first step in the highly respected Certified Wireless Network Professional (CWNP) program. Passing this exam demonstrates that an individual has the core competencies needed to work effectively with wireless technologies, making them a valuable asset to any IT team. This series will break down the key domains covered in the exam. This initial article focuses on the absolute bedrock of all wireless communications: Radio Frequency (RF) theory. Without a solid grasp of how radio waves behave, understanding Wi-Fi becomes nearly impossible. The CWT-100 Exam places significant emphasis on these principles because they govern every aspect of a wireless network's performance, from signal strength to coverage patterns. We will explore the characteristics of RF signals, the units used to measure them, and the environmental factors that impact their propagation, providing a firm foundation for your studies.
In today's digitally connected world, reliable Wi-Fi is no longer a luxury but a necessity. Businesses, schools, hospitals, and public venues all depend on robust wireless infrastructure. The role of the Certified Wireless Technician is to be the hands-on expert who ensures this infrastructure is deployed correctly and operates efficiently. The CWT-100 Exam certifies that a technician can follow a design, properly install access points, terminate cables, and perform basic configuration and validation tasks. This certification is a clear indicator to employers of an individual's practical skills and commitment to industry best practices. Achieving the CWT certification can significantly boost a technician's career prospects. It provides a competitive edge in the job market and opens doors to more advanced roles and specialized certifications within the CWNP track, such as the CWNA (Certified Wireless Network Administrator). For organizations, hiring certified technicians minimizes the risk of improper installations, which can lead to poor performance, security vulnerabilities, and costly rework. The CWT-100 Exam ensures a baseline of quality and expertise, fostering a more reliable wireless ecosystem for everyone involved.
Radio Frequency refers to the range of electromagnetic wave frequencies that lie between 3 kilohertz (kHz) and 300 gigahertz (GHz). These waves are a form of energy that can travel through space, making them the perfect medium for wireless communication like Wi-Fi. Unlike sound waves, which require a medium like air or water to travel, RF waves can propagate through a vacuum. The CWT-100 Exam requires candidates to understand that Wi-Fi operates in specific frequency bands, primarily 2.4 GHz and 5 GHz, with 6 GHz being introduced with newer standards. The fundamental concept to grasp is that data is encoded onto these radio waves through a process called modulation. The transmitter, such as a wireless access point, manipulates a property of the wave—like its height or cycle pattern—to represent digital ones and zeros. A receiver, like a laptop or smartphone, then demodulates this wave to interpret the original data. A solid understanding of this basic transmission process is crucial for troubleshooting connectivity issues and is a core topic for the CWT-100 Exam.
Frequency and wavelength are two fundamental properties of an RF wave that are inversely related. Frequency, measured in Hertz (Hz), is the number of complete wave cycles that pass a given point in one second. For Wi-Fi, we use gigahertz (GHz), meaning billions of cycles per second. The 2.4 GHz band has a lower frequency than the 5 GHz band. Wavelength is the physical distance between two consecutive points on a wave, such as from one crest to the next. As frequency increases, the wavelength becomes shorter. This relationship has practical implications that are tested on the CWT-100 Exam. For example, lower frequency (longer wavelength) signals, like those in the 2.4 GHz band, are better at penetrating solid objects like walls and can travel farther. This is why 2.4 GHz often provides better range than 5 GHz. Conversely, higher frequency (shorter wavelength) signals, like those in the 5 GHz band, can carry more data, leading to higher speeds, but they are more easily absorbed by obstacles and have a shorter effective range.
Amplitude is another critical characteristic of an RF wave, representing its power or strength. Visually, it is the height of the wave from its center line to its peak. A higher amplitude indicates a stronger signal. As a signal travels away from its source, its amplitude decreases due to various environmental factors, a phenomenon known as attenuation. Technicians use tools to measure signal strength, which is directly related to the wave's amplitude. The CWT-100 Exam expects a conceptual understanding of how amplitude relates to signal quality and coverage. Phase, measured in degrees, refers to the position of a point in time on a waveform cycle. A complete cycle is 360 degrees. While a basic concept, phase becomes extremely important in more advanced wireless technologies like Multiple-Input Multiple-Output (MIMO), which uses multiple antennas to send and receive data. By manipulating the phase of signals, MIMO can improve reliability and throughput. For the CWT-100 Exam, knowing the definition of phase and its role in distinguishing one wave from another is a key piece of foundational knowledge.
Decibels (dB) are a fundamental unit of measurement that every wireless technician must understand. A decibel is not an absolute value; it is a logarithmic ratio used to express the difference between two power levels. Using a logarithmic scale makes it much easier to work with the vast range of power values encountered in RF systems. For instance, an increase of 3 dB represents a doubling of power, while a decrease of 3 dB means the power has been halved. A 10 dB increase signifies a tenfold increase in power. The CWT-100 Exam will test your knowledge of two important decibel-based measurements: dBm and dBi. The unit dBm expresses an absolute power level relative to one milliwatt (mW). For example, 0 dBm is equal to 1 mW. This is the most common way to measure signal strength from transmitters and at receivers. The unit dBi, on the other hand, measures the gain of an antenna. It compares the antenna's power output to that of a theoretical isotropic antenna, which radiates energy equally in all directions. A higher dBi value indicates a more focused, directional signal.
When an RF wave travels through an environment, it rarely follows a straight, uninterrupted path. It interacts with objects in various ways, and understanding these behaviors is critical for any CWT-100 Exam candidate. Reflection occurs when the wave bounces off a smooth surface that is large relative to the wavelength of the signal. Metal surfaces, such as filing cabinets or elevators, are common causes of reflection. This can lead to a problem called multipath, where the receiver gets multiple copies of the same signal at slightly different times, potentially corrupting the data. Refraction is the bending of an RF wave as it passes through a medium with a different density, such as from air through glass or water. This can change the direction of the signal. Diffraction occurs when a wave encounters an object with a sharp edge and bends around it. This is why you can sometimes get a signal even when you are not in the direct line of sight of the transmitter. All these behaviors affect the final signal that reaches a client device, influencing coverage and performance. Recognizing materials that cause these effects is a practical skill for a technician.
Attenuation is the natural loss of signal strength as it propagates through space. This loss is a primary reason why Wi-Fi networks have a limited range. The further you are from an access point, the weaker the signal becomes. This concept, known as Free Space Path Loss, is a predictable form of attenuation. The CWT-100 Exam requires understanding that this loss is greater at higher frequencies; a 5 GHz signal attenuates faster than a 2.4 GHz signal over the same distance, contributing to its shorter range. Absorption is a specific cause of attenuation that occurs when an RF wave passes through a material and its energy is converted to another form, typically heat. Different materials absorb RF energy to varying degrees. Water is a significant absorber, which is why the human body (being mostly water) can block Wi-Fi signals. Materials like drywall, wood, and glass are less absorptive, while concrete, brick, and metal are highly absorptive. A wireless technician must consider the materials in a building during installation to ensure adequate coverage.
Free Space Path Loss (FSPL) is the signal strength reduction that occurs as an RF wave travels through an open environment, free of any obstacles. It is a predictable and unavoidable aspect of wireless communication. The two main factors that influence FSPL are the frequency of the signal and the distance it travels. As either the distance or the frequency increases, the path loss also increases. This is a critical concept for the CWT-100 Exam as it explains the fundamental range limitations of any wireless network. While you may not be required to perform complex FSPL calculations on the CWT-100 Exam, you must understand the relationship between the variables. You should know that doubling the distance results in a signal strength loss of approximately 6 dB. Similarly, switching from the 2.4 GHz band to the 5 GHz band introduces significantly more inherent path loss over the same distance, even before considering obstacles. This knowledge helps a technician set realistic expectations for coverage and plan access point placement accordingly.
Mastering the principles of Radio Frequency is non-negotiable for success on the CWT-100 Exam and in a career as a wireless technician. These concepts are not just abstract theories; they have direct, tangible effects on every wireless network you will ever install or troubleshoot. From understanding why a 5 GHz network has less range to knowing how a metal wall can destroy a signal, RF fundamentals provide the "why" behind wireless behavior. A technician who understands these principles can make smarter decisions during installation and diagnose problems more effectively. As you prepare for the CWT-100 Exam, dedicate ample time to this domain. Use real-world examples to solidify your understanding. Think about how reflection from a window might affect a signal in your home or how absorption from a concrete wall impacts coverage in an office. By connecting these foundational concepts to practical scenarios, you will not only be well-prepared to answer exam questions but also equipped with the essential knowledge to excel in your role as a Certified Wireless Technician.
Building upon the foundation of RF theory, the next critical domain for the CWT-100 Exam is understanding the physical components that make up a wireless local area network (WLAN). These hardware devices are the building blocks of any Wi-Fi system. The exam will test your ability to identify different types of hardware, understand their functions, and know their basic characteristics. This includes recognizing various models of access points, client devices, antennas, and the controllers or cloud management systems that orchestrate them. A technician's primary role involves the physical installation and connection of this hardware. A successful candidate for the CWT-100 Exam must be able to differentiate between components and understand how they interact. For example, you should know that an access point provides the bridge between the wireless and wired network, while a client device is the end-user equipment like a laptop or smartphone. This part of the guide will delve into the specifics of each major hardware category, providing the detailed knowledge necessary to confidently answer questions related to the physical layer of a Wi-Fi network.
The access point, or AP, is the heart of a typical Wi-Fi network. Its primary function is to transmit and receive radio frequency signals, allowing wireless clients to connect to a wired network infrastructure, such as an Ethernet LAN. For the CWT-100 Exam, you need to understand the different forms an AP can take. These range from simple consumer-grade wireless routers, which combine an AP, a router, and a switch into one device, to sophisticated enterprise-grade APs that are centrally managed and designed for high-density environments. Enterprise APs can be categorized as either autonomous (standalone) or controller-based (lightweight). Autonomous APs are configured and managed individually, which is suitable for very small networks. Controller-based APs, which are more common in business environments, are managed by a central wireless LAN controller (WLC) or a cloud-based dashboard. This allows for centralized configuration, monitoring, and firmware updates for hundreds or even thousands of APs. Knowing the difference between these architectures is a key topic for the CWT-100 Exam.
While much of the focus in network design is on the infrastructure side, the client devices are equally important. A client device, also known as a station (STA), is any piece of equipment that connects to the Wi-Fi network to send or receive data. This includes an enormous variety of devices, such as laptops, smartphones, tablets, printers, IoT sensors, and point-of-sale systems. The capabilities of the client device often determine the user's perceived performance. Even the best-designed network will perform poorly if the clients have outdated Wi-Fi adapters or inefficient drivers. The CWT-100 Exam will expect you to be familiar with the role of client devices and the components within them that enable wireless communication, primarily the wireless network interface controller (NIC). You should also understand that different clients support different Wi-Fi standards (e.g., 802.11n, 802.11ac, 802.11ax). A technician in the field often has to troubleshoot issues related to specific client devices, so having a foundational knowledge of their function and common problems is essential for both the exam and the job.
Antennas are a critical yet often overlooked component of a wireless network. An antenna is a transducer that converts electrical signals into radio waves for transmission and converts incoming radio waves back into electrical signals for reception. The CWT-100 Exam requires a solid understanding of basic antenna characteristics. The two most important concepts are gain and directionality. As discussed in the RF fundamentals part, gain (measured in dBi) represents the antenna's ability to focus RF energy in a particular direction. Antennas are broadly classified into two types: omnidirectional and directional. Omnidirectional antennas radiate energy in a 360-degree horizontal pattern, similar to a donut shape. They are ideal for providing general coverage in an open area, like a small office or a classroom. Directional antennas, such as patch or Yagi antennas, concentrate the RF energy into a much narrower beam. This allows them to transmit signals over longer distances in a specific direction, making them suitable for point-to-point links between buildings or for covering long, narrow spaces like hallways.
The Institute of Electrical and Electronics Engineers (IEEE) is the organization responsible for creating the standards that govern Wi-Fi technology. The family of standards for WLANs is known as IEEE 802.11. This standard defines how devices communicate over the air, ensuring that equipment from different manufacturers can interoperate successfully. For the CWT-100 Exam, you must be familiar with the key 802.11 amendments, as each one introduced new capabilities, higher speeds, and improved efficiencies. The Wi-Fi Alliance is a separate organization that certifies products for interoperability based on the IEEE 802.11 standard. These amendments are often referred to by their letter designation, such as 802.11g, 802.11n, 802.11ac, and 802.11ax. Each new amendment builds upon the previous ones, introducing new modulation techniques, wider channels, or more advanced antenna technologies like MIMO. A wireless technician needs to understand these differences to select the right equipment, configure it correctly, and diagnose performance issues. For example, a slow network might be caused by an older client device that only supports a legacy standard.
The early 802.11 standards laid the groundwork for modern Wi-Fi. The original 802.11 standard from 1997 was very slow, offering only 1 or 2 megabits per second (Mbps). The first widely adopted standards were 802.11b and 802.11a, both released in 1999. The 802.11b standard operated in the 2.4 GHz band and offered a maximum data rate of 11 Mbps. It was popular for home use but suffered from interference from other devices in the crowded 2.4 GHz spectrum, like microwave ovens and Bluetooth devices. Simultaneously, the 802.11a standard was released, operating in the cleaner 5 GHz band and offering much higher speeds up to 54 Mbps. However, its higher cost and shorter range limited its initial adoption. The 802.11g standard, released in 2003, offered the best of both worlds. It operated in the 2.4 GHz band like 802.11b, making it backward compatible, but it used more advanced technology to achieve the same 54 Mbps data rate as 802.11a. Understanding the capabilities and limitations of these legacy standards is important context for the CWT-100 Exam.
The 802.11n standard, later marketed as Wi-Fi 4, was a significant leap forward for wireless networking when it was ratified in 2009. It was the first standard to operate in both the 2.4 GHz and 5 GHz bands, offering greater flexibility. The most important innovation of 802.11n was the introduction of Multiple-Input Multiple-Output (MIMO). MIMO uses multiple antennas to transmit and receive multiple data streams simultaneously, a technique known as spatial streaming. This dramatically increased the maximum data rate, with theoretical speeds reaching up to 600 Mbps. Another key feature introduced in 802.11n was channel bonding. This technique combines two adjacent 20 MHz channels into a single 40 MHz channel, effectively doubling the channel width and allowing for higher data throughput. These technological advancements made Wi-Fi a viable alternative to wired Ethernet for many applications, including streaming high-definition video. The core concepts of MIMO and channel bonding introduced in 802.11n are foundational for all subsequent standards and are essential knowledge for the CWT-100 Exam.
The 802.11ac standard, or Wi-Fi 5, continued the evolution of wireless technology by building exclusively on the 5 GHz band. Released in waves starting in 2013, 802.11ac focused on increasing capacity and throughput. It expanded on the ideas of 802.11n by allowing for even wider channels, with support for 80 MHz and even 160 MHz channel widths. This is like having a wider highway, allowing more data to travel at once. It also introduced more complex modulation schemes (256-QAM), which pack more data into each transmission. Furthermore, 802.11ac improved upon MIMO technology by introducing Multi-User MIMO (MU-MIMO). While the original MIMO in 802.11n could only transmit multiple spatial streams to a single client at a time, MU-MIMO allowed an access point to transmit to multiple client devices simultaneously. This significantly improved efficiency in environments with many users. As a technician preparing for the CWT-100 Exam, you need to know that 802.11ac only works in the 5 GHz band and understand the key features like wider channels and MU-MIMO that differentiate it from its predecessors.
The latest major standard you should be familiar with for the CWT-100 Exam is 802.11ax, marketed as Wi-Fi 6. While previous standards focused primarily on increasing peak data rates, Wi-Fi 6 was designed to improve overall network performance and efficiency, especially in dense environments with many devices. It operates in both the 2.4 GHz and 5 GHz bands, and its technology is the basis for Wi-Fi 6E, which extends into the 6 GHz band. The headline feature of Wi-Fi 6 is Orthogonal Frequency Division Multiple Access (OFDMA). OFDMA is a game-changer. Previous standards used the entire channel to talk to one client at a time. OFDMA allows the channel to be subdivided into smaller resource units, enabling an access point to communicate with multiple clients simultaneously within a single transmission. This is incredibly efficient for the small, frequent data packets common with today's applications. Wi-Fi 6 also improves MU-MIMO and introduces a feature called Target Wake Time (TWT), which helps battery-powered IoT devices conserve energy.
To succeed on the CWT-100 Exam, you must move beyond simply memorizing the names of hardware components and standards. The exam will test your practical understanding of these topics. You should be able to look at a scenario and identify the appropriate type of antenna to use, or explain why an 802.11ac client cannot connect to a network that is only broadcasting on the 2.4 GHz band. A good study technique is to create flashcards with different devices and standards, listing their key characteristics, operating frequencies, and primary use cases. Review the official CWT-100 Exam objectives and ensure you are comfortable with every hardware and standards-related topic listed. Pay close attention to the differences between the major 802.11 amendments, focusing on what new technology each one introduced. Understanding the evolution from 802.11b to 802.11ax tells a story of increasing speed, capacity, and efficiency. This narrative will help you connect the dots and apply your knowledge effectively during the exam, ensuring you are well-prepared to demonstrate your expertise as a Certified Wireless Technician.
After understanding RF fundamentals and the hardware involved, the next logical step in your CWT-100 Exam preparation is to learn how these components work together to form a cohesive network. WLAN architecture defines the logical structure and operational modes of a wireless network. It is about the rules and building blocks that govern how clients discover and connect to access points, and how multiple access points can work together to provide seamless coverage over a large area. This domain is crucial because a technician must understand the underlying structure to perform installations and basic troubleshooting. The CWT-100 Exam will assess your knowledge of core architectural concepts such as Service Set Identifiers (SSIDs), the different types of Service Sets (BSS, ESS, IBSS), and how Wi-Fi channels are used and managed. This knowledge provides the context for all practical tasks. A technician who understands WLAN architecture can better interpret design documents, configure devices according to specifications, and identify when a network is not behaving as it should. This part will break down these foundational architectural elements.
The Service Set Identifier, universally known as the SSID, is the human-readable name of a Wi-Fi network. When you open your laptop or smartphone and see a list of available networks like "Corporate-Guest" or "Home-WiFi," you are seeing a list of SSIDs being broadcast by nearby access points. An SSID can be up to 32 characters long and is case-sensitive. Its primary purpose is to differentiate one wireless network from another. A single access point can often broadcast multiple SSIDs, allowing it to serve different groups of users with different security policies, such as separating employee traffic from guest traffic. For the CWT-100 Exam, it is important to know that the SSID is included in a special type of frame called a beacon frame, which access points transmit several times per second. These beacons advertise the network's existence and capabilities. While SSIDs can be "hidden" by disabling their broadcast in the beacon frame, this is not a security feature and is easily discoverable with basic scanning tools. A technician is often responsible for configuring SSIDs on access points according to the network design plan.
The Basic Service Set, or BSS, is the fundamental building block of an 802.11 network. It consists of a single access point and all the client devices that are successfully associated with it. All communication within a BSS must go through the access point; client devices in a BSS do not communicate directly with each other in this mode. The AP controls the BSS, managing which clients can join and coordinating the traffic flow. The coverage area of this single access point is known as the Basic Service Area (BSA). A key identifier for a BSS is the Basic Service Set Identifier (BSSID). For a BSS operating in infrastructure mode, the BSSID is the MAC address of the access point's wireless radio. When an access point broadcasts multiple SSIDs, each one will have a unique BSSID, even though they originate from the same physical device. Understanding the one-to-one relationship between a BSSID and a specific AP radio serving a specific SSID is a critical concept for the CWT-100 Exam, as it is fundamental to how clients connect to a network.
While a single BSS might be sufficient for a small home or office, larger areas like a corporate campus or a warehouse require multiple access points to provide complete coverage. An Extended Service Set, or ESS, is created when two or more BSSs are connected by a common wired network, known as a distribution system (typically Ethernet). All access points within the ESS are configured with the same SSID. This allows users to move, or roam, from the coverage area of one access point to another without losing their network connection. To the client device, the entire ESS appears as a single, seamless network. The client only sees the one SSID, and the underlying system handles the transition from one AP to another. This is the architecture used in virtually all enterprise Wi-Fi deployments. For the CWT-100 Exam, you must grasp that an ESS is a collection of BSSs that share the same SSID, enabling mobility. The technician's role is to ensure all APs in the ESS are properly connected to the wired network and configured with the correct network name.
An Independent Basic Service Set (IBSS) is a different mode of operation where client devices can communicate directly with each other without the need for a central access point. This is commonly known as ad hoc mode or peer-to-peer mode. In an IBSS, one of the client devices takes on the role of coordinating the network, sending out the beacon frames and maintaining synchronization. If that device leaves the network, another one may take over. This mode is useful for quickly setting up a temporary network between a few devices, for example, to share a file between two laptops. While not as common in business environments as infrastructure mode (BSS/ESS), understanding the concept of an IBSS is still a requirement for the CWT-100 Exam. It represents a different and simpler network topology. A technician should know that an IBSS is characterized by direct client-to-client communication and the absence of any infrastructure hardware like an access point. This mode is generally less scalable, more difficult to manage, and has limited connectivity compared to an infrastructure network.
Wi-Fi networks operate in specific frequency bands that are divided into smaller segments called channels. In the 2.4 GHz band, there are 11 or 13 channels available, depending on the regulatory domain. In the 5 GHz and 6 GHz bands, there are many more channels available. Each access point in a BSS must be configured to operate on a specific channel. For the CWT-100 Exam, it is crucial to understand that these channels can overlap, which can cause significant performance problems if not managed correctly. In the 2.4 GHz band, the channels are 20 MHz wide but are spaced only 5 MHz apart. This means that many channels overlap with their neighbors. For example, channel 6 overlaps with channels 4, 5, 7, and 8. The only channels in the 2.4 GHz band that do not overlap with each other are 1, 6, and 11. This is why best practice dictates using only these three channels for deployments in this band. The 5 GHz band has more channels and they do not overlap when using standard 20 MHz widths, offering much greater flexibility and capacity.
Proper channel planning is essential for a stable and high-performing Wi-Fi network, especially in an ESS with multiple access points. The goal is to design the network so that adjacent access points are on different, non-overlapping channels. For example, in a 2.4 GHz deployment, you would arrange APs so their coverage areas follow a 1, 6, 11, 1, 6, 11 pattern, ensuring that no two APs on the same channel are close enough to hear each other loudly. This minimizes interference and allows the system to reuse frequencies efficiently. When two or more access points on the same channel are close enough to hear each other, they create a situation called co-channel interference or co-channel contention. Since Wi-Fi is a shared medium, only one device can transmit on a channel in a given area at a time. If multiple APs on the same channel are competing for airtime, it drastically reduces the available bandwidth and slows down the network for all connected users. Understanding this concept is a key part of the CWT-100 Exam's focus on WLAN architecture and troubleshooting.
Roaming is the process by which a client device moves its connection from one access point to another within the same Extended Service Set (ESS). This is what allows a user on a Wi-Fi call to walk down a hallway without the call dropping. The decision to roam is made entirely by the client device, not the access point. The client is constantly listening for beacon frames from other nearby APs on different channels. When the signal from its currently associated AP becomes too weak, the client will initiate a roam to a new AP with a stronger signal. For roaming to be successful, the new access point must be part of the same ESS, meaning it has the same SSID and is connected to the same underlying wired network. The process involves the client sending a reassociation request to the new AP. While the CWT-100 Exam does not go into the deep technical details of fast roaming amendments like 802.11k/v/r, it does require a fundamental understanding of what roaming is, why it is necessary, and that it is a client-driven process. A technician's installation work directly impacts roaming performance by ensuring proper AP placement and overlap.
A wireless LAN is almost always an extension of a wired network. The access points must connect back to the existing network infrastructure, which is typically comprised of Ethernet switches and routers. This connection is what provides wireless clients with access to internal network resources, such as file servers and printers, as well as access to the internet. A wireless technician is responsible for the physical connection of the AP to the wired network, which usually involves running and terminating an Ethernet cable. The CWT-100 Exam will expect you to understand this relationship. You should know that APs connect to switch ports and that this connection provides both data connectivity and, in most cases, power via Power over Ethernet (PoE). You should also be familiar with the concept of Virtual LANs (VLANs). In many networks, traffic from different SSIDs (e.g., corporate vs. guest) is segregated onto different VLANs at the switch level. This requires both the AP and the switch port it connects to be configured correctly to handle tagged VLAN traffic.
Understanding WLAN architecture is about seeing the bigger picture. It is the bridge between the physics of RF signals and the practical task of installing hardware. For the CWT-100 Exam, you need to be able to define the core terms like SSID, BSS, and ESS, and explain how they relate to one another. You must understand the importance of a proper channel plan to avoid interference and the basics of how client devices roam seamlessly across a large facility. This architectural knowledge is what separates a cable puller from a true wireless technician. As you study, try to visualize these concepts. Imagine a single BSS in your home, and then scale that up to an ESS in a large office building. Think about how the channels must be laid out to prevent APs from interfering with each other. By internalizing these structural principles, you will be able to analyze exam questions more effectively and select the correct answer based on a solid understanding of how Wi-Fi networks are logically constructed and how they operate.
This section of our guide for the CWT-100 Exam transitions from theoretical knowledge to the practical, hands-on skills that are the daily responsibility of a Certified Wireless Technician. While the exam is multiple-choice and does not have a practical component, it is designed to validate that you possess the knowledge required to perform real-world tasks correctly and safely. This includes topics like interpreting site survey data, physically installing access points, running and testing cables, and performing basic configuration and verification. A technician is the person who turns a network design into a functioning reality. The CWT-100 Exam will present you with scenarios and questions that test your understanding of the installation process from start to finish. You will need to know about the tools of the trade, best practices for mounting hardware, and the importance of documentation. This part of the series will walk you through the key practical skills covered in the exam, ensuring you are prepared to demonstrate your competence in the deployment of wireless local area networks.
Before any installation begins, a proper plan must be created. This plan is typically informed by a WLAN site survey, which is the process of planning and designing a wireless network to meet specific requirements for coverage, capacity, and data rates. While a CWT-level technician is not usually responsible for conducting the full survey and design, they are often the ones implementing the design. Therefore, they must be able to understand the output of a site survey, which is often a map showing the intended locations of access points. The CWT-100 Exam requires you to be familiar with the purpose and basic types of site surveys. A site survey helps to identify optimal AP locations, discover potential sources of RF interference, and determine the materials and construction of the building, which can affect signal propagation. Understanding a survey report allows the technician to install the equipment in the precise locations specified by the network engineer to ensure the design goals are met. It is the blueprint for the entire installation project.
There are several types of site surveys, and the CWT-100 Exam expects you to know the basic differences. A predictive survey is performed using software. A network designer imports a floor plan of the building into the tool, defines the wall types and materials, and then places virtual access points on the map. The software then predicts the RF coverage, creating a "heatmap." This is often the first step in the design process and provides the initial plan for the installer. Once on-site, a validation survey is performed. This can be a passive survey, where a survey tool simply listens to the RF environment to measure the signal strength of existing APs and identify sources of noise and interference. An active survey goes a step further by connecting the survey client to the network and measuring performance metrics like throughput, latency, and packet loss. A technician may be asked to assist with or perform a post-installation validation survey to confirm that the network meets the design requirements.
A Certified Wireless Technician must be proficient with a variety of tools to perform their job effectively and safely. The CWT-100 Exam will test your knowledge of these essential tools. On the physical side, this includes basic hand tools like drills, screwdrivers, and ladders for mounting access points. It also includes specialized tools for network cabling, such as cable strippers, crimpers for terminating RJ45 connectors, and a punch-down tool for connecting wires to patch panels and wall jacks. In addition to physical tools, a technician uses software and hardware tools for testing and verification. A cable tester is used to verify that a newly terminated Ethernet cable has proper continuity and is wired correctly. A basic spectrum analyzer can help identify sources of RF interference that are not Wi-Fi related, such as microwave ovens or wireless video cameras. Finally, software on a laptop or mobile device can be used to measure Wi-Fi signal strength and perform basic connectivity tests like ping.
The core task of a wireless technician is the physical installation of access points. This must be done according to the site survey design and in compliance with all safety regulations. The CWT-100 Exam will cover best practices for AP mounting. The optimal location is typically on the ceiling in the center of the intended coverage area, mounted horizontally with the dome facing down to match the antenna's radiation pattern. Mounting APs on walls is also common but requires consideration of the directional impact on the signal. Technicians must use the correct mounting hardware for the specific surface, whether it is a drop-ceiling tile, a hard-lid ceiling like drywall, or a wall. The AP should be securely fastened to prevent it from falling. It is also important to consider aesthetics and to place the AP where it is not easily tampered with. Safety is paramount, especially when working on ladders or lifts, and technicians must always be aware of their surroundings, including electrical wiring and fire suppression systems.
Access points require two things to function: a data connection to the wired network and electrical power. In modern deployments, both of these are typically provided by a single Ethernet cable using Power over Ethernet (PoE) technology. This simplifies installation significantly by eliminating the need for a separate power outlet near each AP. The Ethernet cable runs from the AP to a PoE-capable network switch or a PoE injector located in a telecommunications closet. The CWT-100 Exam requires knowledge of these concepts. You should understand the different PoE standards, such as 802.3af (PoE), 802.3at (PoE+), and 802.3bt (PoE++), which define the maximum amount of power that can be delivered. It is crucial for a technician to ensure that the power provided by the switch is sufficient for the access point being installed, as higher-end APs with more radios require more power. The technician is also responsible for running the cable, terminating it correctly, and testing it to ensure it meets performance standards.
While complex network configuration is usually handled by a network administrator (like a CWNA), a CWT is often responsible for some basic initial configuration to get an access point online. In a controller-based environment, this may be as simple as connecting the AP to the network and letting it automatically discover the controller, download its configuration, and join the system. The technician may need to record the AP's MAC address or serial number and assign it to a specific location in the management system. For smaller deployments with autonomous APs, the technician might need to connect to the AP's web-based management interface directly. This would involve setting a static IP address, configuring the SSID and security settings, and selecting the correct RF channel according to the channel plan. The CWT-100 Exam will test your understanding of these basic setup tasks. You should be familiar with the initial steps required to make an AP operational on the network.
After an access point is installed, cabled, powered on, and configured, the final step is to verify that it is working correctly. This is a critical part of the installation process. Verification involves several checks. First, the technician should check the status lights on the AP to ensure it has power and a valid network link. They should then use a client device, like a laptop or smartphone, to confirm that the intended SSIDs are being broadcast. The next step is to connect a client to the network and test for basic connectivity. This includes confirming that the client receives a valid IP address and can access network resources. A simple test like browsing to a website or using the ping utility to reach a known server can confirm this. The technician should also take a measurement of the signal strength in the AP's intended coverage area to ensure it meets the design expectations, a process known as post-installation validation. This confirms the job was done correctly.
Professionalism in a technical role includes thorough documentation. After the installation is complete, the technician is responsible for documenting their work. This might involve updating the network diagrams or floor plans to show the final, as-built locations of the access points. It is also common to label the AP and the cable running to it so they can be easily identified later. Taking photos of the completed installation can also be part of the documentation package. Once verification and documentation are complete, the project is handed over to the network administration team or the client. This handover process ensures that the people responsible for the ongoing management of the network have all the information they need. For the CWT-100 Exam, understanding the importance of these final steps in the installation lifecycle demonstrates a comprehensive and professional approach to the role of a wireless technician. It shows that you understand the job is not finished until the work is documented and formally completed.
The practical skills domain of the CWT-100 Exam is designed to test your understanding of the entire deployment workflow. As you study, focus on the "how" and "why" behind each step. Why is a site survey necessary? How do you choose the right mounting hardware? Why is cable testing important? Think through the process logically, from receiving a work order based on a predictive design to completing the final documentation after a successful installation and verification. This practical mindset will help you analyze the scenario-based questions on the exam. The questions will not just ask you to define a tool but to identify which tool to use in a given situation. By preparing with a focus on real-world application, you will prove that you have the foundational knowledge and problem-solving skills to be a competent and reliable Certified Wireless Technician, ready to contribute to successful WLAN deployments in the field.
