Not sure how your Alvarion 900 was configured, but our you are aware that our 900 and 2.4 have both supported GPS sync since day one right Eight years before Canopy even launched)?

We deployed Alvarion 900 on multiple sites for over a year and it was a less than enjoyable experience. We started by transitioning one site from Alvarion 900 to Canopy 900 and things started working much better. I may use licensed operations as an example only because I've had the experience of being on both sides of the fence. Also we buy GPS sync units as low as $300 new from a 3rd party vendor, as do many canopy operators. As for the excess bandwidth availability in the UL bands, that's definately not the case here...
