Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures <http:// ieee802.org/guides/bylaws/sb-bylaws.pdf>, 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 <stuart.kerry@philips.com> 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 802.11 Working Group.

Month Year doc.: IEEE 802.11-yy/xxxxr0 April 2006 Abstract This presentation addresses issues regarding Clause 20.3.9 of IEEE 802.11p. Specifically, questions/comments regarding regulatory issues, EIRP and transmit mask are approached. Robert Soranno, JHUAPL Robert Soranno, JHUAPL

20.3.9.1 - Power Requirement/Restrictions April 2006 20.3.9.1 - Power Requirement/Restrictions General Issue: Ambiguity in the definition of power levels and EIRP for North American operations Related Comments: 95, 96, 370, 425, 521, 881, 983, 999, 1090, 1196, 1121, 1293, 1329, 1569, 1669, 2074 Recommended Solutions: Move pertinent material to Annexes I and J Remove material that deviates from definitions provided by FCC Robert Soranno, JHUAPL

20.3.9.2 – WAVE Transmit Masks General Issues: April 2006 20.3.9.2 – WAVE Transmit Masks General Issues: Ambiguity in defining mask levels and when to apply them Section is unnecessary as information should be presented in Annexes I and J Specific Comments: 882, 1091, 1570 and 2075 Recommended Solutions: Move appropriate material to Annexes I and J Follow exact model used in Annexes Paraphrase or refer to appropriate FCC rulings whenever appropriate Robert Soranno, JHUAPL

20.3.9.2 – Frequency Stability Requirements April 2006 20.3.9.2 – Frequency Stability Requirements Issue: Provide justification for ±10ppm accuracy Related Comments: 371, 882, 1178, 1179, 1212 and 1997 Recommended Solution: Provide justification in response to comments Justification not needed in the standard Robert Soranno, JHUAPL

20.3.9.2 – Application of Transmit Mask April 2006 20.3.9.2 – Application of Transmit Mask Issue : WAVE transmit mask definition implies absolute attenuation levels – Results in notched spectral mask when station power < max Comment 97 Recommended Solution Spectrum mask actually defines relative spectral shaping limits Reword in Section I using “dBr” as defined in P802.11-REVma/D5.2 March 2006 Robert Soranno, JHUAPL
