Article in GPS World on lab tests showing that 4G cell systems can disrupt GPS. http://www.gpsworld.com/gnss-system/news/data-shows-disastrous-gps-jamming-fcc-approved-broadcaster-11029?utm_source=GPS&utm_medium=email&utm_campaign=Navigate_01_31_2011&utm_content=data-shows-disastrous-gps-jamming-fcc-approved-broadcaster-11029
Detailed test information is in the PDF at: http://www.gpsworld.com/gnss-system/signal-processing/lightsquared-jamming-report-11030 "On January 26, the FCC waived its own rules and granted permission for the potential interferer to broadcast in the L Band 1 (1525 MHz-1559 MHz) from powerful land-based transmitters. This band lies adjacent to the GPS band (1559-1610 MHz) where GPS and other satellite-based radio navigation systems operate." The article implies that the cell phone industry is expecting GPS manufacturers to do the filtering, and, if that is the FCC solution, it would require replacing a lot of equipment. -- R.
