In the face of a supposedly looming “spectrum crunch,” Congress and the President are endlessly threatening/promising to produce a conclusive compendium of where all the usable radio bands are presently located. I’m starting mine now for radio spectrum that is used in one way or another by radio stations—as opposed to TV, public safety responders, and so forth. When I say “radio,” I mean one-point-to-many audio that includes a live component; not person-to-person transmission.
This is a rough list. Feel free to add data, details, corrections, and as patriotic citizens we will submit the final draft to Capitol Hill.
The FM band, where I am a subscriber in crabby standing to no less than three listener supported stations, occupies the 88 to 108 MHz zone.
HD Radio stations broadcast in conjunction with the above analog signals (correct me if I’m wrong about this or it is more complicated).
If you are listening to a radio station via its website on your WiFi enabled computer, you are tuning into the station way up there at 2.4 GHz or 5 GHz.
If you are listening to a station via TuneIn radio on your mobile, well, you could be tuning in on quite a number of data frequencies. Go to Wireless Advisor, plug in your zip code, and it will give you the spectrum ranges for the major carriers.
There is also the Wireless Communications Service band (2305-2320 and 2345-2360 MHz), which hopefully by now is being deployed for broadband service (except the WCS carriers are in a huge fight with Sirius XM over interference, which the FCC has supposedly resolved but you never know . . . ).
Again, any additions and/or corrections to these assertions are very welcome. I’m particularly interested in which mobile bands are getting the most audio data use, given Verizon’s bid to sell off a chunk of that supposedly invaluable 700MHz spectrum it bought back in 2008.
