Greetings Reader,

On Day 2 of the new CWNA 3.0 5-day course we began with Chapter 4 ?¡é?€?¡° RF Math and System Operating Margin. The new animations helped illustrate RF gain and loss. RF math is an important concept that students need to understand and it is covered on the CWNA exam. The basics, i.e. the 3s and 10s of RF math, are covered and students should feel comfortable calculating EIRP and gain or loss in Wi-Fi systems.

Chapter 5 ?¡é?€?¡° RF Power Output Regulations discussed RF restrictions and regulations worldwide. A detailed discussion on FCC regulations is also included.

Chapter 6 ?¡é?€?¡° Wireless LAN Operation covered Wi-Fi products, software clients, and different operating modes such as Ad Hoc and Infrastructure mode. Different AP operating modes are covered as well (root, non-root, repeater, bridge, workgroup bridge). In addition, we talked about PtP vs PtMP bridging, wireless VPN routers, VLANs, mesh networking, wireless controllers/switches, enterprise wireless gateways, and WLAN management solutions. We had some great, in-depth conversations about bridging, mesh networks, and controller-based solutions.

Tomorrow we?¡é?€??ll cover Power over Ethernet, 802.11 communication methods, and WLAN protocol analysis.
