A remote control application for remotely a wireless signal booster is located on a remote device, such as a mobile telephone, tablet or computer. The remote control application utilizes a short-range communication interface, such as Bluetooth. This interface allows the user to autonomously register and remotely monitor the performance of the booster and can typically be used to configure, control, enable, shut down, and perform other operations related to the booster, such providing customer support, product registration, and other types of support for the booster operation. The system is most effective when the external device is a mobile device receiving telecommunication service through the repeater. In this case, the mobile device simultaneously displays two signal strength indicators, one for signals received by the mobile device itself and the other for signals received by the tower-side antenna of the wireless repeater.
