Radio jamming is the deliberate blocking of or interference with wireless communications. [1] [2] In some cases, jammers work by the transmission of radio signals that disrupt telecommunications by decreasing the signal-to-noise ratio. [3] The concept can be used in wireless data networks to disrupt information flow. [4]
This foils jammers which cannot detect this switch in frequency quickly enough or predict the next hop frequency, and switch their own jamming frequency accordingly during the receiving time window. The most advanced jamming techniques have a very wide and fast frequency range, and might possibly jam out an antijammer. [9]
The Enhanced Position Location Reporting System (EPLRS) is a secure, jam-resistant, computer-controlled communications network that distributes near real-time tactical information, generally integrated into radio sets, and coordinated by a Network Control Station. [1] It is primarily used for data distribution, position location, and reporting.
The jamming system is easily controlled and the failures are easily diagnosed. It is controlled on the front panel. The operator can switch on/off particular transmitting systems and subsystems, set up to three jamming sub-bands in each. Dwell time in each sub-band can also be modified. Jammer is equipped with IP, RS 485 and USB interface.
Radio frequency jammers are devices that interfere with communications systems, usually by sending out competing radio signals to confuse nearby electronics. It is a decades-old technology that ...

Limiting unsecure radio communication concerning the jamming and its effectiveness is also important. The jammer could be listening, and if they know that a certain technique is effective, they could direct more jamming assets to employ this method. The most important method to counter radar jammers is operator training.
Once the target frequencies were identified, radio frequency jamming could easily be employed to degrade or completely disable communications. The Have Quick program was a response to this problem. Engineers recognized that newer aircraft radios already included all-channel frequency synthesizers along with keyboards and displays for data entry.
