Boost Weak Cell Phone Signals With a GSM Repeater

Overcome thick barriers and dead spots that kill your cell service with a reliable GSM repeater. This ingenious product repeats your weak cell signal, preventing excessive static, interference and capricious reception. GSM repeaters can be found in new and used condition on eBay.

You must use this GSM (Global System for Mobile communications) repeater with a GSM phone. Nearly every manufacturer makes several phones compatible with GSM. The specific models of compatible phones are too numerous to list here. Luckily, the wide selection of gently used and unused GSM repeater products on eBay can be used with many cell manufacturers you're already family with, such as the following:

• Apple, Acer, Asus
• Blackberry, Casio, Dell, HP
• Huawei, Innostream, Kyocera
• Lenovo, LG, Motorola, Nokia
• Philips, Samsung, Sharp, Toshiba, Verizon

Most GSM repeater products interface between an outdoor and indoor location. The outdoor location entails installation of an omni-directional antenna you can re-position for reception. Choose between GSM repeater products offering remote locations such as in your car, on your boat, on your car roof, random indoor/outdoor, and indoor only. Transmission frequencies vary between products, ranging from 850MHz to 1900MHz. There are no hard and fast rules about where to position any component in your setup. Consider how weak your signal is and any challenges to signaling you need to overcome.

A CDMA (Code Division Multiple Access) GSM repeater merely repeats cell signals for phones receiving service via certain types of carriers. CDMA and GSM are the world's two major cell phone digital radio systems. Most of the world outside of the United States is GSM. However, there are GSM carriers here in the United States, most notably AT&T and T-Mobile. CDMA carriers include Verizon and Sprint. A combined CDMA GSM repeater comes in handy in remote areas where clusters of individuals use cell phones locked to either CDMA or GSM carriers.

Dual Band refers to radio frequency pairs that a phone operates on. In the United States, the most common frequency pair is 850MHz or 1900MHz. Be sure to get a repeater whose transmission frequencies correspond roughly to the frequency pair your phone operates on. Dual Band is not the same as "dB," which denotes "decibel." Often, the vast assortment of products on eBay indicate a specific decibel gain you can expect when you use a specific repeater. This helps you narrow down your choices when it's time to consider how strong a repeater you need and the decibel gain you prefer.
