stds-802-16-tg2: possible PAR changes

["Roger B. Marks" <marks@boulder.nist.gov>]

Phil,

One thing that will kill the approval of a standard is having a draft 
that doesn't match the PAR under which it was created. In this case, 
we need to first change the PAR.

Currently, we have one problem. We have been using the title 
"Recommended Practice for Coexistence of Broadband Wireless Access 
Systems" (and I have submitted a comment suggesting that we add the 
word "Fixed"). The PAR Title is "Telecommunications and Information 
Exchange Between Systems - LAN/MAN Specific Requirements - 
Coexistence of Broadband Wireless Access Systems," so it seems that a 
PAR change is in order.

I am trying to arrange the schedule so we can make the PAR change 
without slowing our progress. I'll keep you abreast of this.

In the meantime, I'd like you to have a look at the rest of the PAR:
	http://ieee802.org/16/tg2/par.html
and see whether we should be changing other items at the same time. 
In particular, could you please take a look at the Scope and Purpose 
Statements below and let me know whether they still apply? They don't 
need to be perfect, since they don't appear in the standard, but they 
ought to be accurate, and we certainly can't go outside the scope.

If it works out the way I hope, we can approve these changes at Session #11.

Regards,

Roger

Scope:

This project covers development of a Recommended Practice for the 
design and coordinated deployment of broadband wireless access (BWA) 
systems to minimize interference so as to maximize system performance 
and/or service quality. This practice will provide for coexistence 
using frequency and spatial separation and will cover three areas. 
First, it will recommend limits of in-band and out-of-band emissions 
from BWA transmitters through parameters including radiated power, 
spectral masks and antenna patterns. Second, it will recommend 
receiver tolerance parameters, including noise floor degradation and 
blocking performance, for interference received from other BWA 
systems as well as from other terrestrial and satellite systems. 
Third, it will provide coordination parameters, including band plans, 
separation distances, and power flux density limits, to enable 
successful deployment of BWA systems with tolerable interference. The 
scope includes interference between systems deployed across 
geographic boundaries in the same frequency band and systems deployed 
in the same geographic area in different frequency bands (including 
different systems deployed by a single license-holder in sub-bands of 
the licensees authorized bandwidth). The scope does not cover 
coexistence issues due to intra-system frequency re-use within the 
operator's licensed band, and it does not consider the impact of 
interference created by BWA systems on non-BWA terrestrial and 
satellite systems.


Purpose:

The purpose of this recommended practice is to provide coexistence 
guidelines to license holders, service providers, deployment groups, 
and system integrators. The equipment parameters contained within 
this practice will benefit equipment and component vendors and 
industry associations by providing design targets. The benefits of 
this practice will include:

*	Coexistence of different systems with higher assurance that 
system performance objectives will be met.
*	Minimal need for case-by-case interference studies and 
coordination between operators to resolve interference issues.
*	Preservation of a favorable electromagnetic environment for 
deployment and operation of BWA systems, including future systems 
compliant to the 802.16 interoperability standard.
*	Optimization of coverage and spectrum utilization.
*	Cost-effective system deployment.
