R18 band selective repeater provides an excellent solution to the problem of poor signal coverage. The R18 amplifies signals to and from mobile phone and base stations and can be used in areas where service is poor. Typical installations might be in basements, restaurants, KTVs, nightclubs, apartments, and parking lots etc. where mobile phone signals cannot penetrate.
The R18 is connected to an outdoor "donor" antenna using a coaxial cable. The donor antenna transmits signals from mobile phones and receives signals from the BTS. Service antennas are placed in communication "dead" zones. Signals from mobile phones used in the dead zones then received by the service antenna and transmitted to the R18 donor antenna, which in turn transmits the signals to the base station.
Easy installation, lightweight design, and ease of use make the R18 a cost-effective and practical method of extending signal coverage.
