In the simplest terms, cell boosters take weak cellular signals and amplify them within a home, office, or building. A typical cell booster kit includes an external antenna (for picking up weak signals), an amplifier (for boosting weak signal), and an internal antenna (for rebroadcasting the amplified signals). But how does one go about selecting the best cell booster?
There are a couple of things to keep in mind when shopping for a booster: application and frequency. There is a difference between a small home cellular repeater and one designed for a warehouse. Large, multi-story buildings or spaces larger than 30,000 square feet often require custom cell booster installation and the expertise of a specialist.
However, for smaller cell booster applications, the most important thing to take note of is frequency. Amplifiers operate on different frequencies including 800 MHz (Verizon, US Cellular, and Alltel), 1900 MHz (T-mobile, Sprint and Metro PCS), and iDEN (Nextel). For those that aren’t sure what frequency their carrier utilizes, a Dual Band booster is probably the best choice. These amplifiers operate on both the 800 MHz and 1900 MHz bands, covering most carriers (with the exception of Nextel).
Basic cell boosters typically fall into the $200 -$250 price range and can be installed with minimal technical assistance.
