Re: Comparison of TG 4j Call for Proposals responses
Abstract: An overview of the areas of agreement between responses to the TG4j CFP and areas in need of further discussion.
Purpose: To outline the points of agreement and differences between the TG4j CFP responses to help drive discussion of the proposals and help move towards consensus.

Attribute Addition to MAC
Need for addition of Phy Information Base (PIB) attribute
Any further attributes needed for MAC?
None identified now, but can be proposed

10. Channelization Issues
<month year>
doc.: IEEE <doc#>
May 2011
Channelization Issues
Need for guard bands at top and bottom band edge
0.5 Mhz guard bands at top and bottom band edge
Possibility to reduce channel spacing to address
Further study required
Problem with 20 mW at top band edge
Reduced duty cycle can be used to address since average power will then be reduced
Not needed within the std
Complex vs Simple Channel Plan
Tradeoff between the flexibility of a complex plan against the extra cost in terms of scanning for channels by the nodes
Need for a default Channel?
Default channel location (2390 proposed)
