Re: [AFMUG] curious, all the spectrums throughput

"Some will say?" Tell that to all of the highly successful ISPs (most of whom are not stereotypical WISPs, but are 95% fiber and 5% microwave) using 60 GHz for 500 to 700 meter distances, places where it could cost $130,000 for a fiber build. 60 GHz, 1.4 GHz wide FDD channels, DQPSK modulation. Real one gig full duplex.  On 2/16/15 11:45 PM, Chuck McCown wrote: The entire radio spectrum  is  infinite in theory as all light, xrays etc are all electromagnetic waves.   The “usable” “RF”  spectrum depends on range and rainfall and other factors.    While some will say that 60 GHz is usable  and THz frequencies are usable and free space optics in IR are usable I would limit the answer to 24 GHz.    So 24 x 12 bits per hz =288 Gbps.    From: That One Guy Sent: Monday, February 16, 2015 4:19 PM To: af@afmug.com Subject: [AFMUG] curious, all the spectrums throughput   Theoretically, based on current bits/hz maximums, and assuming there was a radio capable, and an antenna capable, with no other limitations. What is the maximum throughput of the entire Radio spectrum not going too far into details like processing overhead or any of that.   -- All parts should go together without forcing.
