A mobile blocker is an instrument used to prevent cellular phones from receiving signals from base stations. When used, the blocker 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 blocker is a low output power transmitter with stronger power output which is used to eliminate cellular phone services within a specified space of area. All cellular phone handsets will be in no service status in that area.

As with other radio jamming, cell blocker block cell phone use by sending out radio waves along the same frequencies that cellular phones use. This causes enough interference with the communication between cell phones and towers to render the phones unusable. On most retail phones, the network would simply appear out of range. Most cell phones use different bands to send and receive communications from towers (called frequency division duplexing, FDD). Blockers can work by either disrupting phone to tower frequencies or tower to phone frequencies. Smaller handheld models block all bands from 800 MHz to 1900 MHz within a 30-foot range (9 meters). Small devices tend to use the former method, while larger more expensive models may interfere directly with the tower.

General Features :

To eliminate disturbance of unexpected cellular phone calls in coverage area.
