Here's a couple of snippets from this evenings AMSAT-BB digest. Looks like these wireless cameras are going to cause problems to the Galileo E5 service. Especially as a 200mW version is available on ebay for £15 (Yes, they do actually generate that level of RF power!), there are going to be a lot of them about!

snip ------------------------------------------------- Wireless 1.2 GHz cameras
I just picked up one of these little $60 cameras and am glad to report that they are not in the Amateur Allocation. They are 40 MHz wide each (4 channels) starting at 1060-1100, 1100-1140, 1140-1180, 1180-1220. But I was impressed with their range. An easy 1000' with the supplied receiver. My guess is about 5 milliwatts ERP. The energy at the edges was more than 60 dB down... -------------------------------------------------
snip ------------------------------------------------- Current publicly available Galileo documentation indicates that "Safety of Life" services will be provided on E5a/E5b (1164 to 1215 MHz) downlink and the E2/L1/E1 (1559 to 1591 MHz) downlink. The E6 (1260 to 1300 MHz) downlink is designated for 'commercial services' and not the aviation. Thus, I am VERY curious why the interference to aircraft navigation receivers is constantly brought up in this discussion as it appears a non-player. -------------------------------------------------
