A phone jammer transmits
low-powered 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
conditions, if the distance is close between the cell tower and the
phone jammer, it will have less jamming area. Likewise, if there are
obstacles and walls between the cell tower and 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, buses, etc.)
Theatres (movie
theatres, concert halls, playhouses, opera houses, etc.)
Lecture rooms
Libraries
Museums
Restaurants
Schools and
universities (classrooms, lecture halls, auditoriums, etc.); cell
phone jammers can prevent students from SMS cheating
Places of worship
(mosques, shrines, churches, temples, etc.)
Country clubs
Sporting events
Recording studios
TV stations, radio
stations, etc.
Protects Against Breach of Security Policy
Cell phones are innocent-looking communication devices that enable
continuous transmission of voice/data. In secured places, where policy
does not warrant the use of mobile phones, it is almost impossible to
detect a person conducting cell phone conversations or to spot other
such misuse, especially when mobile phones are very small. Examples of
places where cell phone use may not be allowed include:
Businesses (conferences, board of
directors rooms, seminars, meeting rooms)
Government buildings and government
complexes
Law enforcement facilities
Police stations
Drug enforcement facilities
Prison facilities, jails, etc.
Courts of law and court houses
Embassies
Military installations, military
complexes, and military training centres
Addresses Safety Issues
In accordance with fire code regulations,
mobile phones must be switched "off" in any area that has a potentially
explosive atmosphere, including petrol service stations where sparks
could cause an explosion or fire. These preventable accidents occur more
frequently than most people realize. Areas where mobile phone use is
prohibited include:
Petrol/ gas stations
Oil refineries and storage facilities
Offshore oil platforms
Petrol/gas transportation vehicles
Chemical refineries and storage facilities
Chemical transportation vehicles
Laboratories
Fireworks factories
Liquefied petroleum (LPG) refineries and
storage facilities
LPG transportation vehicles
Natural gas refineries and storage
facilities
Natural gas transportation vehicles
Power plants
Industrial plants (or anywhere the air
contains chemicals or particles such as grain, dust, or metal
powders)
