TG3a PAR
The PAR for TG3a states:
This project will define an alternative PHY clause for a higher data rate amendment to standard
The intent of this project is to provide a standard for a low complexity, low cost, low power consumption alternate PHY for (comparable to the goals for ). The data rate will be high enough, 110 Mb/s or more (see 18a), to satisfy an evolutionary set of consumer multi-media industry needs for WPAN communications. The project will address the requirements to support multimedia data types in multiple compliant co-located systems and also coexistence (18b).

3. TG3a Technical Requirements

TG3a Technical Requirements
Supplements to TG3 Functionality:
It is envisioned that the alt-PHY project will allow supplements to In addition to the PHY itself, the project may include MAC functionality necessary to support the selected PHY.
It is required that the alt-PHY operate with the MAC without fundamental change in operation. It is also required that any enhancements or modifications are enabled by reference to alt-PHY specific PIB parameters.
As an example, from the project request, document 01/532r0 (alt-PHY study group proposal), location awareness is considered as a possible feature of certain alt-PHY technologies and is an example of supplemental MAC functionality. Such a provision may be supported by the PHY PIB parameters in the proposed standard MAC or via supplemental MAC capabilities provided by the alt-PHY project.

4. Some Comments about Changes
12Sept2003
Some Comments about Changes
Channel time allocation not optimized for MPEG-2 variable bit rate streams
MAC support for Mesh networks
MAC too complicated for simple video applications
Ranging/location/identity

5. Most of these changes require new PAR

Most of these changes require new PAR
Not required to support new PHY
Apply to current GHz PHY as well as UWB PHY
Would apply to any new PHY (e.g., mmW or 5 GHz) adopted by WG.
