These tests showed that in the presence of moderate-to-strong signals in a first adjacent channel, the detection threshold sensitivity of all of the devices was severely impacted.
For some of the devices, the degradation in the detection sensitivity was as much as 60- 70 dB.
In some cases, the degradation was such that the detection threshold could not be measured.
This could impact significantly the ability of the devices to reliably detect TV signals within stations’ service areas."

"In some instances, the Adaptrum, I2R, and Motorola (in sensing only mode)
devices incorrectly reported channels as unoccupied (available) when the
WSD was operated within a station’s service contour and the signal was
viewable."

BTW, anyone who has seen what a mess the FCC database currently is has to wonder how well geo-location will work.]]> http://www.dslreports.com/forum/remark,21276524 Thu, 16 Oct 2008 10:22:51 EDT
