Commercially available repeaters used in trunking systems are generally expensive, not portable and fixed in location. These repeaters also transmit at high power on fixed channels. Such repeaters are therefore not flexible or economical for portable low cost use. For example, conventional repeaters are not practical for expanding activities or events which only needs a small coverage area.
