How to Choose a Cell Repeater

Posted by Perception System Tuesday, September 13, 2011

You're tired of experiencing poor cell phone reception, dropped calls and poor voice quality. You get some reception outside your home or office, but as soon as you step inside it seems to magically disappear. Your phone is constantly scanning for a signal, so your battery dies much faster than it should. You've double checked your phone and called your carrier, all to no avail.
You need a cell phone signal booster.

How Cell Repeaters Work

Cell repeaters, also known as cell amplifiers, cell extenders or cell boosters, are fairly simple to use. Most boosters consist of three major components: an external directional antenna, an internal antenna and a signal amplifier.

The external directional antenna is typically placed outside the home or office (preferably outside a window or on a roof) and is positioned to face the nearest cell tower. In the event that you are installing the antenna yourself, a signal strength monitor is recommended to help you figure out the best location for the antenna. The external directional antenna is designed to pick up the weak signal that is being broadcast by your cellular provider.

The signal the external antenna picks up is sent over wires to the signal amplifier. The signal amplifier is what increases the signal. Your boosted signal is then sent to the internal antenna which wirelessly rebroadcasts a more powerful signal within your space.

How to Differentiate Between Cell Boosters by Frequency

Cell boosters operate on different frequencies: 800 MHz, 1900 MHz and iDEN. The 800MHz frequency is compatible with Verizon phones outside of Florida and Texas, Alltel phones in selected states, and US Cellular phones in selected states. T-mobile, Sprint, Metro PCS and several other carries operate on the 1900MHz band. AT&T operates on both bands.

Often the most comprehensive solution is to opt for a Dual Band Cellular Repeater. These repeaters operate on both the 800 MHz and 1900 MHz bands, ensuring proper coverage with all major carriers (with the exception of Nextel). Nextel users in need of a cellular repeater must invest in an iDEN booster.
