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 802. 19. Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures <http: // ieee 802. 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 TAG 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 <shellhammer@ieee. org> 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. 19 TAG. If you have questions, contact the IEEE Patent Committee Administrator at <patcom@ieee. org>. Submission 1 Kyung-Kuk Lee, Orthotron Co.

September 2005 doc. : IEEE 802. 19 -05/0038 r 0 Strategy • Define assumptions for interfering device – TX spectral mask – TX power – Hopping probabilties (if any) – Duty cycle • Define assumptions for interfered Rx device – Packet size – RX input filter (bandwidth and shape) – BER as function of interference plus noise power – Calculate the interference power for different frequency and distance scenarios • Assume the receiver of the interfered system to receive 10 d. B above its specified sensitivity – Calculate the SINR for the different frequency and distance scenarios – Calculate the resulting BER – Calculate the resulting PER – Visualize the PER for the different frequency and distance scenarios Submission 5 Kyung-Kuk Lee, Orthotron Co.
