Below attached email is the closest detailed description of someone running Rocket M with GPS, was posted on WISPA_UBNT list.
Folks @ Ubiquity have stated this before... The GPS option is not to get more Performance on a single link... but is to allow radios (AP's) to exist on the same tower or roof top to use overlapping frequencies when pointing in different directions.. and provide stable performance under these circumstances... i.e. performance with GPS on will be less than without GPS. and FWIW.. check the firmware you are using.. 5.4.3 is more stable, but 5.5beta4 is also getting close to a full release.. ========================= On 6/24/2011 3:45 PM, Chuck Hogg wrote: > I wanted to touch base as this is our first case of actually using > GPS/AirSync.
