Posted on 28th Oct 2015 @ 10:18 AM

It is a trend that mobile phone blockers are used in prisons to block calls and tests phones of inmates inside.Such as the Alabama Department of corrections,Montgomery has planed to do that in some prisons.They planed to install a “managed access” system for correctional facilities,three prisons in Elmore County.

Besides,the department asked the Alabama Legislature for another $4 million to install similar systems at Bibb,Donaldson,Fountain and St. Clair correctional facilities.Prison guards said inmates use phones to conduct scams on the public,extort money from relatives and coordinate drug drops at prisons,they have to stop that.

The best equipment to block mobile phone is mobile phone blockers,for using in prisons ,we recommend the model,70W High Power Cellphone Signal Jammer for 3G 4G LTE with Directional Antenna.The mobile phone blocker is a large-medium size device fixed in prisons,in those areas where there may be some prisoners hid in and use cell phones.2G 3G 4G mobile phones are out of working ,calls and texts can’t made and received.That is why Alabama prisons installed mobile phone blockers.

The blocker we are talking about comes with a metal appearance ,to protect components and parts inside -- you know ,maybe some prisoners hate and do something bad to it...And,there are different buttons for switching to different channels to block frequencies.From the appearance we see there are two cooling fans for heating dissipation, keeps the unit cooler and giving it much more stable performance and better range.Integrated circuit protection to prevent damage in the event of antenna short circuiting or disconnection.And the mobile phone blocker is about 19kg--it is a stationary signal blocker for prison.

The device covers about 20-100 meters (radius)@-75 dBm,of course,it depends on the signal strength in the areas.By the way,the mobile phone blocker also can be used in other private and public places.
