Cell phone amplifiers are mobile phone devices used for augmenting signal strength for a better reception in areas where there are little or no signal at all. They are designed to amplify incoming and outgoing signals. They also reduce the chances of getting dropped calls and signal fades while improving transmission range, voice quality, and access. Cell phone amplifiers are commonly used in transit and in areas with weak cellular signals. Some models can only work with specific phone types and networks, while others can be used with multiple phones and networks.
Cell phone repeaters are amplifiers with no wiring systems. They allow calls to get through even in dead zones. Repeaters produce clear and strong signals, increasing the clarity and range of incoming and outgoing call signals.
Cell phone inline boosters are amplifiers that use wiring systems to work. They are attached to phone units. Some inline boosters require antennae and adapter cables.
Multi-phone use: For flexibility and convenience, choose a cell phone amplifier that can be used with various cell phone types, models, and networks.
Automatic signal adjustment: Look for a cell phone amplifier that can automatically adjust the signal level according to the condition of the environment, so you do not have to set it manually.
Frequency: Cellular signals come on two different frequencies: 800 and 1900 Mhz. Find out which frequency your network provider uses in your area and make sure your repater is compatible. In most cases, T-mobile and Sprint PCS use only the 1900 Mhz frequency band. To be sure, contact your network.
