In October 2009, Dr. Pete Welcher presented these slides at a Bluesnet Network Advisory Group meeting in Santa Barbara, CA. This presentation covers Wireless LAN (WLAN, WiFi, 802.11) Project Management — things you really ought to know before you start an 802.11 WLAN project, especially info to gather before you do the Site Survey. It’s no longer about basic coverage, it’s about what degree of and quality of coverage is appropriate. And I’m told it can be 30% or more cheaper to get it right up front.

Note added (1/27/10): another factor for pre-site-survey planning is WIPS plans. For monitor / rogue-locating APs, Cisco is saying about 1:5 ratio to regular AP’s, with one per every 15,000 to 35,000 square feet, approximately (depending on walls, etc.). The site survey just needs 1-6 Mbps data rate coverage, not full coverage.
