A test performed by Progeny of whether its Canopy network will cause harmful interference to Part 15 licensees “was defective” and “significant interference concerns remain,” the Wireless Internet Service Providers Association said in a filing at the commission (http://xrl.us/bm5cy4). “Progeny…

tested its equipment in a single area, Santa Clara County, California,” WISPA said. “This location is not representative of most American cities. Although Progeny claims that the need for their system is highest in areas with ‘urban canyons’ where signals from GPS satellites are more frequently blocked, the physical geography as well as the urban topography of the Santa Clara Valley is the opposite -- a flat valley of mostly single story stucco residences with some two-story ’tilt-up’ commercial buildings.” Progeny also tested “only one make and model of outdoor fixed broadband equipment,” WISPA said. “Even if all the other Progeny test conditions and assertions were consistent with real-world conditions -- which they most certainly were not -- the testing of only one single outdoor device is an utterly inadequate sample size for anyone to reasonably conclude that Progeny’s testing was complete and dispositive.” Progeny said in a March filing the test shows its Multilateration Location and Monitoring Service (M-LMS) “will not cause unacceptable levels of interference to Part 15 devices in the 902-928 MHz band.” “The filing of Progeny’s test report follows a lengthy development process, which included operating an experimental M-LMS network in the San Francisco Bay Area for more than two years without any complaints of harmful interference to Part 15 devices in the 902-928 MHz band,” Progeny said (http://xrl.us/bm5c2d). Progeny said the service it has developed will provide “critically-needed position location services” for wireless customers making E911 calls. “Progeny’s location technology produces high yield and accuracy (including elevation accuracy) even in urban canyons and deep indoors where existing position location services are severely challenged,” Progeny said.
