Amobile blocker is an instrument used to prevent cellularphones fromreceiving signals from base stations. When used, theblocker effectivelydisables cellular phones. These devices can be usedin practically anylocation, but are found primarily in places where aphone call would beparticularly disruptive because silence isexpected.
Mobileblocker is a low output power transmitter withstronger power outputwhich is used to eliminate cellular phoneservices within a specifiedspace of area. All cellular phone handsetswill be in no service statusin that area.
As with other radiojamming, cell blocker blockcell phone use by sending out radio wavesalong the same frequenciesthat cellular phones use. This causes enoughinterference with thecommunication between cell phones and towers torender the phonesunusable. On most retail phones, the network wouldsimply appear out ofrange. Most cell phones use different bands tosend and receivecommunications from towers (called frequency divisionduplexing, FDD).Blockers can work by either disrupting phone to towerfrequencies ortower to phone frequencies. Smaller handheld modelsblock all bands from800 MHz to 1900 MHz within a 30-foot range (9meters). Small devicestend to use the former method, while larger moreexpensive models mayinterfere directly with the tower.
General Features :
To eliminate disturbance of unexpected cellular phone calls in coverage area.
All specified frequency bands will be paralyzed simultaneously.
Uses very low output power to transmit signal and does no harm to human health.
The coverage area is a sphere area with its effective distance measured in the radius.
Effective distances : Approx. 15-30 feet (in radius)*
All regional operated frequency bands built in one box to meet different region needs
Compact size and light weight
Can be installed and operated by yourself
No adjustment is required
