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
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 c 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

Follow up presentation on May 8th
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
