Major manufacturers mainly sell jamming equipment to the military and law enforcement agencies and report the sale, but selling equipment to everyone requires the buyer to be responsible for ensuring the legality of the buyer. Obligation to purchase, own or use equipment. The mobile phone industry opposes the use of these devices, and many people have invested money to label mobile phones to solve the growing problems of mobile phone users.
The Air Force, responsible for the deployment and maintenance of GPS satellites, recognizes that GPS systems are vulnerable because they are widely available to the public. Of course, GPS and cell phone jammers are not the most advanced technologies. In fact, devices that cause signal confusion and interference are like illegal cell phone jammers. For aircraft that use ground radar equipment for route navigation and have a satellite-independent backup navigation system, the risk is low. Military personnel use a dedicated GPS network. However, because the pilot had to switch to a backup navigation system, GPS interference could cause chaos in the cockpit. Maritime transportation that requires GPS coordinates to find the location of the port can also cause problems.
This is why Russian portable jammer and the new “special force” anti-drones that use them are not necessarily a danger to the survival of US military drones. Russian GPS jammers may have difficulty finding targets. A former U.S. drone developer who asked not to be named said: “Unless you know where and when they are, it seems difficult to do it.”
With the insightful or embarrassing photos of people browsing the Internet without knowing it, camera phones are prohibited in locations across the country, including many health clubs and schools. Sensitive government and corporate buildings are also trying to keep cell phones out, and a few states are considering new jammer laws to limit their use.
A technical countermeasure is in progress. British company Iceberg Systems has launched a system called “safe haven”, which can disable the camera part of the phone, while not retaining other functions. Locations using such “private areas” will send a shutdown signal to a specially equipped video phone or digital camera.
