Cell phone jammer.
A phone jammer transmits low power radio signals to cut off communications between cell phones and cell base stations. It does not interfere with any communications other than cellular phones within the defined regulated zone. Upon activating a phone jammer, all idle phones will indicate "NO NETWORK." Incoming calls are blocked as if the cellular hand phone were off.
When the phone jammer is turned off, all cell hand phones will automatically re-establish communications and provide full service.
The jamming area is influenced by the location of the cell tower and the obstacles between cell tower and the cellular jammer. It means that in normal condition if the distance is close between the cell tower and the phone jammer,Cell Phone Jammer
Total Output Power: 20 Milliwatts
Effective distance: 0 to 10 metres (in optimum conditions)
This handheld cell phone jammer comes complete with battery, charger and carry case. Optional accessories: Car charger lead, direct connect adaptor, spare battery - buy these at bottom of this page.
This cell phone jammer model comes in 2 versions, one for Europe, North Africa and the Gulf states GSM networks (900 & 1800) and one for the Americas & Canada (800 & 1900 mhz) networks.

A mobile phone jammer is an instrument used to prevent cellular phones from receiving signals from or transmitting signals to base stations. When used, the jammer effectively disables cellular phones. These devices can be used in practically any location, but are found primarily in places where a phone call would be particularly disruptive because silence is expected.
Mobile phone jammers are just that – they jam your phone so that you can’t get a signal.
When they are set up, these devices basically block the signals to and from mobile phones within a specific area.
In the past there have been calls for them to be installed in theatres so that performances aren’t interrupted by phones going off.
Theatres
People have also suggested that they could be used in school exam halls to ensure that pupils don’t cheat by seeking outside assistance with questions.
But the problem is that jammers are likely to affect wider areas and other frequencies than those they are intended for.
6. Operation temperature: 0 to 50 degrees
7. Humidity: 5% to 80%
it will have less jamming area. Likewise, if there are obstacles and walls between the cell tower & the cellular phone, the jammer will give more jamming area.
Provides Acoustics Isolation.
A phone jammer provides the ultimate solution in any area where cellular communications frequently cause nuisance either by loud incoming call rings or resulting loud telephone conversations. Examples of places where cell phones can be disruptive include:
. Public Transport (trains, busses, etc.)
. Theatres (movie theatres, concert halls, playhouses, opera houses, etc.)
. Lecture rooms
. Libraries
. Museums
