Re: [802-20-GENERAL] Fwd: 802.18 SG1 PAR and 5 C

Title: RE: [802-20-GENERAL] Fwd: 802.18 SG1 PAR and 5 C
I heard much of this discussion in the 802.18 Study Group 1meetings. I think can provide some clarification based on my understanding. Please rely on Carl Stevenson for verification.
 
Regarding the first point, 802.18 sees the resulting standard as international. The range 54 MHz - 862 MHz is meant to encompass VHF and UHF terrestrial TV bands worldwide.  TV bands in any one country will be a subset.
 
As for the second point, as Dave indicates, the planned frequency range for MBWA includes VHF and UHF bands as does the 802.18 PAR. The distinction I then see is that the focus of the 802.18 PAR is on operation secondary to TV broadcasters in their licensed assignments. MBWA is intended for primary operation by wireless operators in their licensed assignments. 
 
Best regards,
 
Steve Crowley

I have the following concerns related to the PAR on the unlicensed use of
the VHF/UHF TV broadcast bands:

1. According to Section 12, Scope of Proposed Project, the project is targeting
"fixed point-to-multipoint wireless regional area networks operating in the VHF/UHF
TV broadcast bands between 54 MHz and 862 MHz".  However, the frequency range given
actually overlaps the US cellular spectrum at 824-849 MHz and the public safety
bands at 806-824 MHz and 851-869 MHz.  Also, several UHF TV channels have already
been reallocated to other uses including commercial mobile radio services (CMRS) in
channels 52-59 (698-746 MHz) and public safety in 764-776 MHz and 794-806 MHz.  In
addition, the FCC has announced that the proposed spectrum sharing will not be allowed
in channels 2-4 (54-72 MHz), channel 37, and channels above channel 51.   

2. According to the 5 Criteria section on Distinct Identify, "No current 802 wireless
standard specifies operation in the VHF and lower portion of the UHF spectrum, i.e., the
TV bands...."   However, this seems to be partially incorrect since the 802.20 PAR states
that 802.20 will address systems "operating in licensed bands below 3.5 GHz".

All,
The 801.18 Study Group on TV band sharing has approved a PAR and 5 Criteria for requested approval by the 802 Executive Committee at the July Plenary.

Please provide me with any comments. Also if you have specific questions, please direct them to Carl Stevenson, the chair of 802.18 and myself.

Regards,
Jerry Upton
