We are currently using the 3.5mhz channel. We are getting exactly what the link budget table says in the manual.
3.5mhz channel (75% downlink) will give you 13mb/s in MIMO B. Next modulation down is around 6mb/s, which is what most SM's link up at. -Eric On 12/17/2010 9:18 AM, Carl Shivers wrote: > Thanks for the info and the link to the .pdf.
