giammaiot2 on twitter has a long history of trying to use science sensors to detect intentional RF interference, e.g. this post with a map from the Advanced Microwave Scanning Radiometer (AMSR) looking at 7 GHz: https://x.com/giammaiot2/status/1919493425100988490 https://x.com/giammaiot2/status/1919493425100988490
Or this thread from 2023 looking at SMAP: https://x.com/giammaiot2/status/1770815247772729539 https://x.com/giammaiot2/status/1770815247772729539
- anthomtb 1y agoThank you, that map is fascinating. Jamming in and around conflict zones (Ukraine, Myanmar) and in China make sense to my Western brain. But why so much interference in Japan?
- LarsAlereon 1y agoIt seems it's because Japan allows LTE service on 1427.9Mhz and higher. It looks like Europe starts at 1452Mhz, and the US keeps this entire band clear from consumer applications.
