The act of jamming signals was widely used during World War II and the Cold War. Besides using it to disrupt messages from reaching their intended countries, jamming of broadcast stations was also propagated back then. During the Cold War period, the broadcasters from the Soviet and the West even battled in a “power race” in which the mobile phone jammer worked to increase their transmission powers.
The situation started changing at the end of the Cold War. As the Soviet Union fell from power, the Western forces gained more traction and control over innovation and technology in general. However, with no need for “signal battles,” signal jamming was also classified as an illegal act among many countries, with the exception being for government, military, and defense applications.
Electrical Jamming
A strategy wherein jammers send interfering and highly-concentrated signals to radar or receiver either through noise or repeater techniques. Noise jamming is divided into three types namely spot, sweep, and barrage.
Blocking of Cellphone Usage in Schools or Prisons
Signal Jamming devices are very popularly used in environments where mobile phone use is not allowed. A school is a place where they are commonly used since they help take out the distraction that smartphones pose on education. A cellphone blocker from The Signal Jammer is a good option, and can also be used for either personal (as long as it’s legal) and organizational purposes. Prison is another example where it is not uncommon for inmates to successfully smuggle a smartphone despite restrictions. Signal Jamming is used in this situation as a safety precaution since it works to block off all possibility of communications from inside the prison to the outside world.
Privacy Purposes
GPS jammers are types of signal jamming devices that work by blocking possible GPS monitoring on devices or vehicles. They can also be paired with a GPS Tracker Detector which can be used to spot bugs planted on a person or their vehicle.
India NAGPUR: Sadar police on Wednesday arrested one Deepak Ledwani, a resident of Jaripatka, for running away with a signal jammer put on his four-wheeler by Nagpur traffic police.
Police constable Sayed Ahmed attached with Sadar traffic zone on Tuesday put a tyre jammer on a wrongly parked car bearing number MH-31-FA-3911 on Mount Road, to ensure the driver was forced to pay a fine for traffic violation.
When Ledwani returned to his vehicle, he saw the jammer and decided to take matters into his own hand. He allegedly unscrewed the wheel along with the jammer and put in the back of his vehicle. He replaced the wheel with a spare and drove off.
Later, Sayed lodged a complaint of theft against the car owner and on Wednesday the police traced the owner and arrested Deepak Ledwani. The police produced him before the court which granted him bail on deposit of personal bond of Rs15,000.
Meanwhile, Ledwani has been fined Rs3,800 by the traffic police for keeping the jammer with him from the day of the incident till Wednesday. It is learnt that he did not pay the fine. There is a provision to levy a fine of Rs50 per hour on the driver who does not approach the vehicle after seeing the jammer on his car. If a vehicle is parked in a no-parking area, the traffic police can impose a fine of Rs250.
To prevent the car from being tracked, you can use a portable handheld GPS jammers, carry a car charger, and provide wireless battery life for your jammer without worrying about the battery. Portable design is convenient for your travel and you can use it anywhere.

All states and Union territories can now secure Central funds for buying body worn cameras for their prison staff to capture incidents of indiscipline and violence in jails and also for installing technology-based mobile phone jammer solutions to block unauthorised use of cell-phones by the inmates.
As part of the modernisation of prisons project, the ministry of home affairs shall offer grants in aid to the states for a period of five years starting with the current financial year, for deploying modern-day security equipment in prisons for their enhanced security and also to facilitate the task of reformation of prisoners through correctional administration.
As per guidelines for implementation of the modernisation of prisons project, shared recently by the home ministry with the chief secretaries or administrators of all states and UTs, the funds can be released by MHA for upgrading all categories of jails like Central jails, district jails, sub-jails, women’s jails, open jails and special jails. The funds shall be released for purposes such as creating a video conference infrastructure to enable online trial of high-risk prisoners; body worn cameras to keep a vigil on conduct of the jail staff as well as activities of prisoners; modern gadgets for access control; mobile phone jamming solutions to restrict use of cell-phone smuggled in by inmates; and correctional programmes for prisoners, including their counselling, therapy and vocational training. The funds may also be utilised for setting up small industrial units in jails which will provide opportunity of labour to the inmates and generate revenue for jails, besides providing on-the-job vocational training and skills.
While the role of the MHA would include developing overall strategy for modernisation of prisons and monitoring and evaluating the project, the states will be required to procure equipment, update database of prisoners, furnish periodic funds utilisation reports and maintain the procured jammers gps equipment.
Funds under the prisons modernisation project will be released by MHA each year during the period from 2021-22 to 2025-26, on the recommendation of a steering committee. The release of funds in subsequent years will be based on utilisation certificates furnished by the states in respect of funds released during the previous years.
