What can cell phone jammers be used for?
Known as cell phone blockers or jammers, cell phone jammers are devices that obstruct radio signals, affecting cellular networks, Wi-Fi, and GPS systems through the emission of radio waves. These devices generally operate within a range of 10 to 40 meters.
Both the military and government have developed systems that can effectively interfere with radio communications across extensive areas.
By utilizing jammers, retailers can obstruct customers from conducting price comparisons within the store, which can lead to an increase in their sales.
In specific settings that demand quiet or reduced distractions, signal jammers prove to be beneficial. They can eliminate interruptions caused by ringing cell phones in theaters or chatter among youth in schools.
It is possible for criminals to utilize jammers to hinder the functionality of wireless alarm systems and other radio connections, which can prevent emergency calls from being placed via the mobile phone network.
WiFi Interference
- How it works: WiFi uses the 2.4GHz or 5GHz frequency band. Jammers emit powerful signals in the same frequency band, causing data communications between the router and the device to be blocked.
- Impact: Internet access becomes slow or disconnects completely, and devices cannot connect to the wireless network.
GPS Jamming
- How it works: GPS signals operate on higher frequencies such as the L1 band (1575.42 MHz). Jammers cover these frequencies by emitting noise signals, making it impossible for GPS devices to receive location signals from satellites.
- Impact: Navigation devices cannot determine location, and time synchronization may also be affected. Some devices that require precise positioning (such as drones or logistics tracking systems) will fail as a result.
Cellular Network Jamming
- How it works: Cellular networks (such as 2G/3G/4G/5G) use different frequency bands. Jammers block communications between base stations and mobile phones by emitting strong signals on these frequency bands.
- Impact: Mobile phones may not be able to make calls, send text messages, or use mobile data.
