What does a wireless extender do?

A wireless extender aka cellular repeater as the name suggests enhances a cellular signal by repeating and extending the signal. Repeaters tend to vary by how far they extend a signal and which frequencies they support. A premium cellular repeater like the ones created by Wireless Extenders can extend a signal by 2,500 square feet and operate on multiple frequencies (800/850 MHz and 1900 MHz) fully supporting 3G.

Components

• A typical cellular repeater will include an outdoor/indoor antenna that captures the cellular signal. This can be on the roof or indoors near a window or in the attic.
• A coax cable is connected to the outdoor/indoor antenna to transfer the signal to a base that amplifies the signal.
• Then another antenna takes the amplified signal and broadcasts it throughout the home.

The system both broadcasts and receives cellular signals greatly increasing the reception you get in your home. Below is a picture of the Wireless Extenders YX510-PCS-CEL Dual-Band Cell Phone Signal Booster, one of the best systems at a reasonable price.
