FCC to Reorganize 800mhz Band?
nick0909 writes "Years in the making, the FCC is finally
close to deciding if they will allow Nextel to pay for the reorganization of the 800mhz bandplan. In return the FCC will give Nextel a new band in which to operate their phones, where they won't destroy public safety communications. Other cell companies are angry because they had to pay millions for their GHz frequencies, and argue Nextel is getting off cheap. On top of this, if the 800MHz band gets re-sliced, will the FCC continue to push TV broadcasters out of 700MHz, which was supposed to go all to public safety in the coming years?"
900 MHZ, as someone already posted.
But on a related note, I have some pro-audio wireless mic gear that uses 800MHz; I think it's fairly common in UHF pro gear. I'd really hate to have to replace this stuff because I can't get a clean signal for my band gigs, and I'm sure I'm far from alone here. (And that leads me to a digression - I wish more of this pro gear would use programmable oscillators/ frequency synthesizers so they wouldn't lock you into just one or two frequencies. Bleah...)

When I think 800mhz I think VHF UHF my self. Some people prefer to call it VHF for some reason.
Cable Channels 126-141 805.25-895.25mhz according to my Kworld video card. I've never seen these used.
UHF channel 69 801.25mhz.. 70-83 I believe were the ones realocated to celular 806-890mhz.

I'm less familar with the 800mhz emergency frequencies.
900mhz I believe is what you're thinking of... I'm a cheep bastard and I own a pair of 900mhz cordless phones.

Getting a license from the FCC is like buying a house. It's in your interest to know your neighbors and to make an effort to be a good neighbor. With that in mind, here's a few notes on what this whole fuss over interference is really about.
1. direct interference - someone transmits on someone else's frequency. This happens occassionally by accident and usually gets fixed quick. Nextel was once fined for doing this unintentionally a few years ago near New Orleans, LA.
2. co-channel interference - two entities each have a license to use the same frequency in geographically overlapping areas. The two parties are mutually responsible for making equipment and operating adjustments to eliminate interference.
3. equipment mis-configuration (including co-located equipment) - different companies often share the same tower sites and often the signal from one company's transmitter will "leak" into another causing mixed products and emissions outside licensed frequencies.
4. receiver desensitivity caused by proximity to low elevation, high power transmitter sites (ie. cell towers).
Nextel is causing problems for other 800Mhz licensees mostly as a result of items 3 and 4. Non-Nextel cell towers (like Verizon, Sprint, and AT&T) also cause #4 above but the problem is more severe when near a Nextel tower site because the transmissions are in the same band as the other non-Nextel users' equipment.
