Designing HD WLANs
Designing HD WLANs
Hi Community Member!
Designing HD WLANs was a presentation I gave at Airheads Conference Las Vegas 2012 in March. I would like to share this now with the larger Airheads Social Community since there has been so much interest.
This session will explain how to implement an Aruba 802.11n wireless network that must provide high-speed access to an auditorium-style room with 500 or more seats. Aruba Networks refers to such networks as high-density wireless LANs (HD WLANs). Such coverage areas have many special technical design challenges. We will cover the design principles, capacity planning methods, and physical installation knowledge needed to successfully deploy HD WLANs.

Introducing the HD WLAN Capacity Planning Methodology
Step 1: Determine Device Count
Step 2: Determine Channel Count
08:53-12:29 Overlapping vs. Stacking
12:30-13:45 Channels Allowed by National Regulatory Agency
13:46-15:42 20 MHz vs. 40 MHz Channels
15:43-18:50 To DFS or Not to DFS? Dynamic Frequency Selection (DFS)
