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.ppthttps://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
