Cellular Boosting

Cellular Communication Issues

The security business is changing as rapidly as it is advancing, but with improved technology comes unintended consequences not foreseen until they are actually realized. Such is the case with security transmissions and the advanced use of cellular technology to transmit data, signals and alerts. Today, all advanced security businesses providing commercial and even residential security applications are abandoning hardwire for wireless, cellular communications. Congested space coupled with variations in cellular signals present transmission challenges. Cellular signals can also be hampered by certain building materials used in construction, like low eGlass, metal, concrete, also foliage, and cellular tower configuration with different carriers providing signal paths. The answer is installing products provided by manufacturers like SureCall, that detect, boost and correct weakened cellular signals.

Even first-responders have a protocol that their two-way radios have to work within any structure to ensure communication consistency as a safe guard to themselves and others. SureCall has a cellular boosting system that ensures these responders are in constant, uninterrupted communication. These cellular boosting systems are paramount in protecting the rules governing first-responder procedures that must be met.

What is a Cellphone Signal Booster?

Cell phone signal boosters are bi-directional amplifier (BDA), a name commonly used in the wireless telecommunications industry. These devices are used to boost cell phone reception in a local area by using a reception antenna, signal booster and an internal rebroadcast antenna. These technical applications are similar to the cellular broadcast towers used by network providers broadcasting. The units are of course much smaller and usually intended for use in one building or a common structure. Modern cellular signal boosters basically rebroadcast the cellular signals inside a building. The system uses an external directional or omni-directional antenna to seek out and collect the best cellular signal available, which is then transmitted to a booster unit that amplifies the signal. This in turn re-transmits that signal locally, which provides a significantly improved signal strength thus improving communication when its needed, 24/7.An additional advantage of using cell phone repeaters is an increase in the cell phone's battery life. This is primarily due to the lower power required to broadcast the signal to the bi-directional signal booster, due to its proximity to the phone.
