  1. RR-TAG Liaison ReportIEEE 802.18 - 802.22 2008-05-15 • >. Authors: Peter Murray, TMG, Inc.

  2. IMT-Advanced • Call for IMT-Advanced/Next Generation Networks Technology Proposals from IEEE 802 Working Groups • See 11-08-0624-00-0000-call-for-IMT-Advanced-technology-proposals.doc Peter Murray, TMG, Inc.

  3. UWB • IEEE L802.16-08/030d1- Public consultation on Draft ECC Report 120 (“Technical requirements for UWB DAA (Detect And Avoid) devices to ensure the protection of radiolocation in the bands 3.1-3.4 GHz and 8.5-9 GHz and BWA terminals in the band 3.4-4.2GHz”) • This document was approved by 802.18 for transmission to the ECC Peter Murray, TMG, Inc.

  4. Hearing Aids • 15-08-0356-00 presentation was made on Hearing Aids by Starkey Laboratories Joel Solum on their need to have 15.247(a)(2) section modified by rule making. Currently there is a Waiver on this section for 902-928 MHz. Peter Murray, TMG, Inc.

  5. 60 GHz conference calls 802.19 April 2008 • Joel T. Johnson from IEEE Geoscience and Remote Sensing Society (FARS committee) and Ohio State University raised concern regarding potential for interference from 60 GHz 802 devices to passive microwave systems on earth observing satellites conducting meteorological observations • https://mentor.ieee.org/802.19/file/08/19-08-0013-00-0000-coexistence-issues-for-passive-earch-sensing.ppt • In initial coexistence analysis he showed that the satellite can only tolerate one device per square kilometer transmitting with EIRP of 1 Watt • Comments on the call included: • Satellite measurement bandwidth is 100 MHz, where as 802.15.3c is ~2GHz. Difference in bandwidth needs to be accounted for • Calculation assumed device on the ground pointing directly up to satellite, need to adjust for gain in the direction of the satellite • Calculation assumed device on the ground has 100% duty cycle • There was no account for attenuation from indoor to outdoor • Whether this is a regulatory issue or standards issue Peter Murray, TMG, Inc.

  6. 60 GHz conference calls 802.19 May 2008 • Minutes from the 2008 conference calls are contained in https://mentor.ieee.org/802.19/file/08/19-08-0014-01-0000-60ghz-conference-call-minutes.doc • Follow up presentation on May 8th • https://mentor.ieee.org/802.19/file/08/19-08-0013-01-0000-coexistence-issues-for-passive-earch-sensing.ppt • Corrected a significant equation error: satellite can tolerate 1000 devices per square kilometer transmitting with EIRP of 1 Watt • Modified equations to include parameters for • difference in bandwidth between transmitter and satellite passive receiver; tolerable density becomes 20000 • expected transmit antenna properties as well as through wall-attenuation, roofing, scattering Peter Murray, TMG, Inc.
