60 GHz band Conference call in April 2008 October 2006 doc.: IEEE 802.11-06/1560r1 May 2008 60 GHz band Conference call in 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 Eldad Perahia (Intel) Matthew Fischer (Broadcom)
60 GHz band Conference call in May 2008 October 2006 doc.: IEEE 802.11-06/1560r1 May 2008 60 GHz band Conference call in 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 Eldad Perahia (Intel) Matthew Fischer (Broadcom)
