Here’s what you’ll learn in each video of the CWTS Certified Wireless Technology Specialist series:
Video 1 – “Introduction to Certified Wireless Technology Specialist (CWTS)” – This introductory Nugget to the CWTS series covers an exam and certification overview, exam objectives, and best practices for the getting the most out of this CWTS CBT Nuggets.
Video 2 – “The Wireless Networking Industry” – This nugget covers standards and regulatory bodies such as the IEEE, governing bodies like the FCC, and the Wi-Fi alliance. There is also a brief survey of the 802.11a, 802.11b, 802.11g, and 802.11n standards. The WMM, WMM-PS, WPS, WPA, and WPA2 implementations are also introduced.
Video 3 – “Basic Wi-Fi Technology (Part 1)” – Topics in this first technology nugget include: infrastructure vs. ad-hoc mode; service sets; active and passive scanning; authentication and association; frequencies and channels; and data rates vs. throughputs.
Video 4 – “Basic Wi-Fi Technology (Part 2)” – In this continuation of basic technology we will cover: range, coverage, and capacity; dynamic rate switching, channel re-use and co-location; distribution system and roaming; power-saving options and protection mechanisms.
Video 5 – “Radio Frequency Mathematics” – Yes – there will be math! But don’t fret because it won’t be painful. Let’s talk about Watts, Milivolts, Decibels, dBm, dBi, and EIRP.
Video 6 – “RF Fundamentals (Part 1)” – Here is the first fundamental discussion of radio frequency wireless properties. The topics covered include: wireless characteristics, interference issues, line-of-sight, fresnel zones, RSSI, and SNR.
Video 7 – “RF Fundamentals (Part 2)” – This nugget covers the characteristics of spread spectrum technology and more including spread spectrum concepts, DSSS, OFDM, as well as channel overlap and re-use.
Video 8 – “Antenna Properties” – In this exploration of antenna theory we will discuss polarization, diversity, and antenna categories such as omni-directional, semi-directional and fully directional. Different types of antennas are investigated including rubber duck, patch, panel, yagi, parabolic dish, and grid. This nugget finishes up with antenna accessories like arrestors and connectors.
Video 9 – “Antenna Practice” – We go deeper into omni directional, semi-directional, and fully directional antenna implementation. We explore additional topics like azimuth and elevation charts, antenna usage, link budget, antenna mounting, and antenna accessory deployment.
Video 10 – “Wireless Infrastructure Hardware” – Here is an excellent exploration of a wide variety of wireless LAN components including access points, wireless bridges, wireless routers, repeaters, WLAN controllers, and PoE devices.
Video 11 – “WLAN Client Components” – Its time to take a look at the end station side of the wireless equation. Here we look at layer 2 and layer 3 connectivity, client hardware components like PC cards and wireless USB, and accompanying client utility software.
Video 12 – “Wireless Design Fundamentals” – This design nugget covers a number of wireless scenarios including: Small Office/Home Office (SO/HO), Branch-Office/Remote-Office (BO/RO), building-to-building, public wireless hotspots, municipal-law enforcement, corporate guest wireless vlan, wireless ISP, and planes/trains/automobiles.
Video 13 – “Site Surveying and Installation (Part 1)” – Part one of site survey concepts covers the following topics: information gathering, physical and data security requirements, site-specific documentation, as well as documenting the network, connectivity, and power. You will also learn how to understand RF coverage, client connectivity requirements, and antenna usage and placement.
Video 14 – “Site Surveying and Installation (Part 2)” – This nugget is a continuation of the previous one as we explore MCA and SCA; active and passive surveys; manual vs. predictive methods; surveying mesh access; using protocol and spectrum analyzers; and site survey best practices.
Video 15 – “Troubleshooting the WLAN” – Troubleshooting is one of the most valuable skills that a wireless network engineer can possess. This nugget explores decreased throughput, connectivity problems, weak signal strength, and issues with device upgrades.
Video 16 – “Optimizing the WLAN” – Let’s take a look at optimization in the form of hardware selection and placement, addressing interface issues, client load-balancing, analyzing client capacity and utilization, as well as multi path and hidden node.
Video 17 – “Wireless Security (Part 1)” – The first WLAN security nugget covers legacy protections like SSID hiding, MAC filtering, and WEP; user-based security like 802.1X; pass phrase-based security; push-button/pin-based security; and TKIP and CCMP encryption.
Video 18 – “Wireless Security (Part 2)” – This final nugget of the CWTS series continues the security coverage with topics like VPNs, wireless IDS/IPS, captive portals, and regulatory compliance issues like HIPAA and PCI.
