How Do The Signal Boosters Work?
The Problem
A mobile phone is connected to a mobile network tower through mobile signal. However, sometimes mobile signal is inhibited or blocked by trees, hills, construction materials or bad weather. When this happens phone calls are dropped, voice quality is reduced, or a slow data connection is experienced by the mobile phone user.
The Solution
CEL-FI products improve signal between a mobile phone and a mobile network tower, allowing you to have clear voice conversations and a stable data connection inside buildings. The CEL-FI solution takes the mobile signal that is available, amplifies it and rebroadcasts it in the areas where it is required.
At its most basic, each CEL-FI system consists of a donor antenna, a mobile signal booster and a server antenna. The donor antenna is placed in the area where the strongest native signal can be received from the carrier network (signal levels as low as -120 dBm are acceptable); this is usually outside or close to a window. The donor antenna transmits the native mobile signal to the CEL-FI mobile signal booster unit which amplifies the signal. The server antenna communicates wirelessly with the mobile signal booster and broadcasts the enhanced mobile signal in the interior of the building with significantly enhanced signal levels, thus enabling better quality calls and greater data throughout.
In larger or more complex environments additional antennas can be used to increase the coverage area, and if necessary multiple systems may be combined.
