IIRC, 3.65 ghz rules allow 1 watt EIRP per each mhz of bandwidth, thus a 7.5 Mhz Radio would be allowed 7.5 Watts of EIRP, 10 Mhz radio would be 10 Watts EIRP ...
Redline cert does not reflect this... don't know why Airspan certification does get really close to it Mind me but 10 Watts EIRP if allot (about 40 db) Vendors should seek maybe 15 or 20 mhz channels Gino A.

Mike's comments below are accurate with regard to Redline's equipment. However, it should be noted that Redline was not able to get their gear certified at the full power output allowable for 3.65. It is for this reason that Redline does not believe its gear will work in rural markets. Remember, 3.65 was originally supposed to be for the rural market, which means either Redline went wrong somewhere or the FCC did. Additionally, Redline has not sought to get its indoor CPE certified for 3.65 because of the power issue. That means urban operators are not able to offer self-install options that would greater speed up the rollout process. I believe WISPA should be working with the 3.65 radio vendors and the FCC to get things fixed such that there will be a greater opportunity for operators to provide services using 3.65. -Matt Mike Hammett wrote: > The guys at Redline said their equipment is power limited due to FCC > limitations. > > My point of view is based on Redline's statement of what their gear can do > coupled with the documents filed with the FCC for their certification. > > The most I could get out of a PtP link was about 7 miles.
