Release: The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE Working Group.

Document describes scope of P work, but also includes discussion about related areas that may be spun off as P1900.X projects. “Anticipated Structure of P1900.2” looks very similar to work. Steve S also sent him 0031r0 as a liaison describing the work in for the meeting held last week. Next two meetings are Nov 7-10 in Baltimore and Mar 7-10, tentatively in Bolder. Steve S will arrange a conf call with Steve B in the next couple of weeks to answer questions that came up today, discuss possibility of collocation, etc.

Jim also showed video of spectrum analyzer results showing how UWB signal could be notched out to avoid interference with an incumbent (0035r0).

There is also an accompanying 0028r0 Word document providing a more detailed description. The approach is based on starting with a symbol error rate (SER) instead of a bit error rate (BER) for determining packet error rate (PER).

This is a Powerpoint version of 0032r0 Word document. Discussed each comment and came to resolution. Results captured in 0036r1
