GPS jamming is a particular type of GNSS interference. Under ITU rules, countries are obliged to eliminate harmful interference through GPS jamming and spoofing, but the ITU lacks effective enforcement measures. [2] The ICAO legal framework requires that countries should implement appropriate prevention and mitigation of GPS jamming and ...
Estonian Foreign Minister Margus Tsahkna's accusation, for which he provided no proof, followed Finnair's decision to pause flights to Tartu in eastern Estonia for one month due to GPS disturbances.
CDMA can also effectively reject narrow-band interference. Since narrow-band interference affects only a small portion of the spread-spectrum signal, it can easily be removed through notch filtering without much loss of information. Convolution encoding and interleaving can be used to assist in recovering this lost data. CDMA signals are also ...
In the UK Ofcom now permits the use of GPS/GNSS Repeaters [31] under a 'light licensing' regime. Due to the potential for both natural and man-made noise, numerous techniques continue to be developed to deal with the interference. The first is to not rely on GPS as a sole source.

In addition, dynamic radio frequency interference is expected to occur in the scenarios related to cognitive radio, where the networks and the devices should exhibit frequency-agile operation. Chirp modulation can be seen as a form of frequency-hopping that simply scans through the available frequencies in consecutive order to communicate.
Professional wireless microphones used the 700 MHz band until 2010 when they were made illegal, but equipment still exists in use that may interfere with 3G and 4G technologies. [ 10 ] Due to immediate adjacency to channel 51 lower 700 MHz A block license holders were prohibited to use it within channel 51 station service areas.
Calls can also be dropped if a mobile phone at the other end of the call loses battery power and stops transmitting abruptly. Sunspots and solar flares are rarely blamed for causing interference leading to dropped calls, as it would take a major geomagnetic storm to cause such a disruption (except for satellite phones ).
