have a wireless network setup for a customer. It is an outdoor wireless setup. The area consists of 4 mobile homes arainged in a square formation. There are two ap's installed diagnally from each other, one on channel 1 and the other on channel 11. Each is using one 5.2dBi omni antenna mounted 10' high. There is a courtyard in the middle with a table. At the table which is about 20' from either antenna the best I can get is 18Mb with fair quality (17dB SNR).
The ground was some sort of crushed rock, 6" deep and quite wet. The ground was saturated.
Any idea why signal was so bad at such a close ranged? Could the saturated ground be soaking up the signal?
I ran Airmagnet, both spectrum analyzer and WLAN ananlyzer and found no sources of interference and no obvious trouble with the connection.
