Introduction L27DE0-GSM smart line amplifiers can be deployed as a cheap solution for implemented with BTS or repeater for indoor coverage extension. In the past due to limitations in the available technology, line amplifiers were considered as an interfering source to the BTS, as a result it has not been widely adopted by service providers.
Remotek has developed a smart line amplifiers that is able to mitigate the interference. It is developed with an interference level detection circuit, which automatically sets the relevant parameters to minimize the interference effect to the mobile network system.
