MMDS/ITFS/BRS is approximately 190 MHz (I don't remember what the FCC's fiddling at the lower end to create BRS out of ITFS/MMDS added or subtracted.

5.4 GHz band is 255 MHz.

Original 800 MHz cellular spectrum was 50 MHz and sparked cellular telephone industry in the US using analog technology.

So, stating "only" 50 MHz at 3.65 GHz may well not evoke much "empathy" at the FCC.

FYI, my math on license-exempt use of the "WHOLE TV band" is:

Channels 21 – 36 (512 MHz – 608 MHz) = 96 MHz
Channels 38 – 51 (614 MHz – 698 MHz) = 84 MHz
Total 180 MHz in 6 MHz increments.

Understood. But it is only 50 mhz. How much is itfs? How much is mmds? How much was the new 5.4 gig band?

Part of what we're looking for is the WHOLE TV band.

I remember Patrick saying that none of you manufacturers were at all excited about 3650 because there just wasn't enough spectrum there to make it useful! My how times change. grin.

Your point is well taken though. What would you suggest as an alternative?

What are other people's thoughts?
