[WISPA] Power Lines in the LOS path

2007-04-11 Thread Jim Stout
I hate to ask this question, but I'm at my wit's end with this one. I recently installed a new customer (2.4 GHz) with a clear LOS to my tower. The distance is less than a mile and I get -56 dBm of signal strength. I've run a spectrum analyzer and it's dead silent when the radio's off.. All

Jim, I have run into very similar situations, where high power lines, were the only explanation as to the interference. I was able to work around it in some situations by adjusting the customer antenna to shoot under the powerlines, however, this is not always possible, nor is it always the

Yeah, that sounds like multipath. I've seen that a few times. Your signal level is actually much too high. Try two things to test my theory. Turn the antenna backward. That should cut 15 to 20dB of signal off and get you down into the high 60 to mid 70 rssi range. Much more reasonable.

I've also had some luck in moving the antennas. Should have mentioned that before. I had one customer get 3 or 4 x the speeds just by moving his antenna UP by 2'. Had another one double the speeds by moving it DOWN 4'. marlon - Original Message - From: Jaron Parsons [EMAIL

Agreed there. I moved a unit from one end of a house (clear path, but power lines) to the other end, and lower (under the power lines) and seen a dramatic increase even though the signal level was similar in both places. - Original Message - From: Marlon K. Schafer [EMAIL PROTECTED]
