End frustrations from dropped calls. Improve data rate and extend your mobile devices¡¯ battery life.
Opisys¡¯s compact repeater systems are ideal for home / home offices and small offices applications. Typical repeater systems consist of an outdoor antenna, an inside antenna, a bi-directional amplifier, and RF cables to connect them together as needed.
On the down link, an outside antenna captures outside cellular signals and brings them inside through a RF cable. Bi-directional amplifier (BDA) boosts the signal and sends them out toward your cellular phone and other mobile devices through the inside (service) antenna.
On the Up-Link, the process is reversed, where the signals go from your mobile devices to the inside antenna, BDA, and outside antenna toward a base-station.
Opisys can provide you with each of these components separately, or as a complete kit including everything you need for the installation.
