If you keep the signal levels up, so that the data rates stay up (all stay above -73), you can move about 6-8 mbit in a 5 mhz channel at 900.
I've been using UBNT radios and star-os to drive them. 900 mhz is VERY prone to interference, the RSSI levels are hugely affected by weather, humidity, and things like "snow on the ground". Snow raises my client's RSSI by anywhere from 5 for the strongest to over 20 db for the weakest. Clients that are -82 in the summer are -60 or so in the winter - when there's snow on the ground. Just raining, and then falling below freezing will do a 3-8 db gain in RSSI. As you say, OFDM at 900 Mhz is one fascinating exercise. ++++++++++++++++++++++++++++++ Neofast, Inc, Making internet easy 541-969-8200 509-386-4589 ++++++++++++++++++++++++++++++ -------------------------------------------------- From: "Josh Luthman" <j...@imaginenetworksllc.com> Sent: Thursday, May 06, 2010 8:23 PM To: "WISPA General List" <wireless@wispa.org> Subject: Re: [WISPA] Looking for iput on 900MHz H-Pol Sector Choices.
