[Recommended] Wireless LAN Professionals Podcast

Just finished listening to http://www.wlanpros.com/wlw052-7-rules-accurate-site-surveys/ by Keith Parsons.

Highly recommended – a very good summarisation of site survey lore:

  • What do do on a site survey
  • What not to do on a site survey
  • How can others cheat on a site survey (= do not do it)
  • Active vs Passive survey
  • Spectrum analyzers
  • And more

P.S. Check out the web page for PDF white papers that summarize the podcast!

Everything below is applicable both to small home networks with off-the-shelf consumer-grade routers using stock and advanced (DD-WRT, etc) firmware, as well as to enterprise-grade gear and networks. Thus, to keep it simple, I will be using the home WLAN as an example, since even the most advanced admins and most proficient engineers still live in residential areas with high neighbour AP density, and everyone wants fast and reliable Wi-Fi.
