I did not realize this was the wireless list and not the Moto List Moto uses 9MHz channels so the 3 non-overlapping are 906, 914, and 924 - CH1 = 902-910 - CH2 = 911-919 - CH3 = 920-928
I can't speak from experience to co-locating multiple 900AP's on a tower without sync. I would think trying to get 3 10MHz channels on the same tower would present a significant limit to the # of subs you could get per AP. However 5MHz channels might provide some decent scalability as long as you aren't trying to provide speeds much more than 3Mbps down but that's just a guess - Jerry -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Philip Dorr Sent: Sunday, August 08, 2010 5:32 PM To: WISPA General List Subject: Re: [WISPA] Second 900mhz AP Was that even legal? I thought the 900 MHz spectrum that we are allowed was 902-928.
