Re: B5-Lite

I know it'll result in the air interface coming down on the M series, but verify your noise with the AirView tool. I've 
grown to not trust the noise floor measurement. 40 MHz at that supposed amount of SNR should be rocking almost double 
what you're getting. With the V and H chains that far apart, alignment might be off. What are your CCQ, AMC and AMQ 
numbers?

I’m seeing -61 (63/67 V/H) with floor at -101 right now with the XW PowerBeam 400 w/ 40mhz. The speeds are “Ok” but 
getting beyond 60Mb/s is hard as the CPU maxes in a bridged setup. Doesn’t seem to have any issues with the wireless 
rate during load, so perhaps it’s not doing offload to the chipset right? The goal is to improve capacity in the 
interim while some strategic fiber is deployed for some areas. A pair of B5s or AF5X would likely work out but would 
rather spend that on fiber.
