Cell Block Technologies, Inc. provides the only cost-effective, non-jamming, extensible solution today, to enforce a no-cell-phones or no-mobile-phones policy and to address other problems faced with cell phone / mobile phone and wireless communications in public and private spaces. Cell-Block-R Control Units prevent the use of cellular phones within restricted areas. This is accomplished using a patent-pending technology that takes control of the cellular phone away from the public cellular phone networks. Any incoming calls then go into voicemail at the public cellular phone network and the Control Unit will not allow any outgoing calls. The Cell-Block-R Control Unit is about the size of a residential smoke detector and can be attached unobtrusively to the ceiling or floor of a building to effectively prevent cell phone operation within a fixed radius. The
Basic Control Unit covers a radius of 6 ½ feet (two meters).
With this radius, a single unit will control
approximately 100 sq feet of floor space, 10 Control Units for
1,000 sq. feet, etc. Other models cover different size
areas - up to 10,000 sq. feet (1,000 sq. meters). The
actual combination of models to be used in any specific
application will depend upon the area to be covered. The
low power Control Units are recognized as a base station by
cell phones / mobile phones within its radius.
(Think of a “base station” as a “tower”.)
Once the Cell-Block-R Control Unit has “captured” the
phone, it instructs the phone to go to a channel that is not
active in that cellular system.
This prohibits the phone from receiving communication
from the original system’s base station. With
multiple Cell-Block-R Control Units, an establishment can cover
as much or as little area as needed.
The limited radius of each control unit gives total
flexibility to create “cell phone / mobile phone free” or
“cell phone / mobile phone available” zones without
spillover into areas that are not covered. |
Control Units The Control Unit takes control of all cellular phones within its Zone of Protection. Control Units are pre-set at the factory with a spherical Zone of Protection that is approximately 6 feet (2 meters) in diameter. Control Units may be reset at installation to provide varying size Zones of Protection as appropriate for the specific site and to activate various alarms and other settings as desired by the customer. The maximum Zone of Protection for a single control unit is 100 feet (30 meters) in diameter, although the maximum would seldom be used. Multiple Control Units may be used to cover larger restricted areas. Remote Management Units Remote Management Units provide for the networking of Control Units to monitor the status of the Control Units. This can be important where the administration must ensure that all units are working and none have been damaged – for example, in prison environments. The Remote Management Unit is also used to facilitate the initial setup of Control Units and to service the Control Units when new electronic upgrades are needed. Alarms may be sent by the control units to the RMU when needed, for example, the detection of a phone in a prison or a power outage. A normal installation will include multiple Control Units and a single Remote Management Unit. The RMU is necessary for updating the software as well as for changing the factory installed settings in the Control Units (such as the size of the Zone of Protection). For very small areas, a single control unit may be installed without the use of an RMU; however, there will be no networking and no status monitoring. If the software needs to be upgraded, the VAR must return with a personal computer and an RMU to provide service.The Cell-Block-R Control Unit is not a cell phone jammer. |
