Re: [WISPA] Frequency Planning
Use LOW power and really good antennas. Use both polarities etc. How many radios per tower? Basically, when possible, think of a honey comb. Each flat side gets it's on freqency, no two sides that touch each other (including the corners) get the same band. marlon - Original Message - From: Andy Trimmell atrimm...@precisionds.com To: WISPA General List wireless@wispa.org Sent: Tuesday, December 08, 2009 9:47 AM Subject: [WISPA] Frequency Planning Anyone have any suggestions for a program that we can use to document frequencies that is easy to use?

Re: [WISPA] Frequency Planning
Marlon, no two sides that touch each other (including the corners) get the same band. Are you saying you have, say, 2.4 on one corner and then 5 on the corner the 2.4 is closest to?

Re: [WISPA] Frequency Planning
No. Use 5725 on one side, 5850 on the other. Don't use 5735 or 5840 on either adjacent side if you can help it. If you are doing this with 2.4 you are pretty well screwed :-). There just isn't enough spectrum to do it nicely. Keep the TX power REALLY low and make up for it with bigger client side antennas. If it's PTP links, this gets a lot easier. This isn't exactly the right thing but it'll get you some idea of how this can work out: http://odessaoffice.com/wireless/fh_vs_ds.pdf At some point in the past BreezeCOM (Alvarion today) had a nice pdf on this topic.

Re: [WISPA] Frequency Planning
Oh, okay. I was confused with the band I thinking 2.4 and 5. Makes sense though, I try to actually do that although sometimes I screw myself with having other AP''s down the road on channels that will conflict with the new one. Takes more planning that I ever have time for or are allowed to have. :) Bob- -Original Message- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Marlon K.
