Hi Travis, The 18, 23, and 24 (UL) GHz Dragonwave products do downshift to QPSK from QAM; their 11 GHz product does not. I believe that this shift is already figured into Dragonwave's uptime figures.
Your 28 mile link sounds like a good bet to me, but you might want to analyze maximum rainfall over the last four years to the maximum historical record for 100 years. I'm sure Dragonwave would be happy to help you justify the purchase of another link. Do you have raw data / graphs you could share of the performance of your Dragonwave links? I'd like to see if I can find a correlation between historical rainfall data and changes in your signal levels Best, -- Dylan Oliver Primaverity, LLC -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
