Right now it is in draft but very close to going to the next stage. But
there is a lot more going on here than just a standard.
- The 802.22 is setting a precedence, besides the engineers that are
creating 802.22 also involved are the incumbents that hold the TV channels
and they have been very valuable in making the standard will not interface
with digital TV and vice versa. And the FCC has to be an integrated part to
make 802.22 THE standard for data whitespace as they have with ATSC, the
only way this is going to happen is if every WISP gets involved now.
- We need to get the FCC to do a light licensed in the same way
3.65Ghz has been done, at least for part of the band. The channels we are
talking about are VHF and UHF from 2-51 (not including 37) which are as
follows for the US:
VHF UHF UHF
UHF
Channel Frequency Channel Frequency Channel Frequency
Channel Frequency
2 54Mhz 14 471.25Mhz 27
549.25Mhz 40 627.25Mhz
3 60Mhz 15 477.25Mhz 28
555.25Mhz 41 633.25Mhz
4 66Mhz 16 483.25Mhz 29
561.25Mhz 42 639.25Mhz
5 76Mhz 17 489.25Mhz 30
567.25Mhz 43 645.25Mhz
6 82Mhz 18 495.25Mhz 31
573.25Mhz 44 651.25Mhz
7 174Mhz 19 501.25Mhz 32
579.25Mhz 45 657.25Mhz
8 180Mhz 20 507.25Mhz 33
585.25Mhz 46 663.25Mhz
9 186Mhz 21 513.25Mhz 34
591.25Mhz 47 669.25Mhz
10 192Mhz 22 519.25Mhz 35
597.25Mhz 48 675.25Mhz
11 198Mhz 23 525.25Mhz 36
603.25Mhz 49 681.25Mhz
12 204Mhz 24 531.25Mhz 37*
609.25Mhz 50 687.25Mhz
13 210Mhz 25 537.25Mhz 38
615.25Mhz 51 693.25Mhz
26 543.25Mhz 39
621.25Mhz 52 699.25Mhz
* Cannot be used
As you can see there is a large jump from VHF to UHF. We have already
confirmed we can make two radios, one for the lower VHF bands covering the
156Mhz that could be used as well as one to cover UFH which is 228Mhz wide.
>From a manufacturing perspective it is not cost effective to make a radio
that covers 645Mhz, even 228Mhz is pushing it.
- From the table above it seems very simple, to me at lease, use VHF for the
Wireless Innovation Alliance
(http://www.wirelessinnovationalliance.com/index.cfm) and UFH for WISP using
part 90 light licensed using 802.22 in this part of the band.
- The reason for this is two-fold, first the incumbents are already
working with 802.22 and without them on our side it is going to be very hard
to get this done. Don't forget DTV is first tier in the band everything else
is 2nd tier we must not interface and the 802.22 protocol make sure of this.
Second, is the flip side, the WIA does not have the incumbents support (from
what I read anyone this is my option only!) and it trying to make the white
space another Wifi which as all WISP know will not work well for outdoor
networks!
- I highly recommend that everyone takes the time to read the FULL 802.22
spec as it really is all WISP have ever wanted in a protocol! I am CC Carl
Stevenson on this email as he is the chair of IEEE 802.22 and he can double
check the above to make sure there are no issues.
- Comments?

What is the status of this? I am investigating it more since Tony made
reference to 802.22. I became interested when I saw a provision for channel
bonding.
Have there been any references to a 3.65 esque license so the bands won't be
filled with junk?
