WiFi For those interested, here are the results of my research in order to properly compute WiFi propagation (at 5 GHz) over ground without any trees, obstacles or whatever. Fading has been observed and I’d like to find out a formula that allows to compute it :
- Few base concepts regarding radio propagation : http://www.csdptt.org/article410.html (in French)
- Rice model propagation (mentioned in the previous document) : http://flattop.its.bldrdoc.gov/itm.html
Stay tuned!

Linux,
WiFi In order to stay up to date with ath9k linux driver, I decided to test it on a laptop. I have used an AR5418 (MB72) miniPCI card for this test and wireless-testing kernel (v2.6.32-rc7-43014-g505f756). I wanted to use this card in order to monitor 802.11n networks. Here is the result.
