Repeater with carrier-specific information

A repeater comprising:

• a first port;
• a second port;
• a first amplification and filtering path coupled between the first port and the second port, wherein the first amplification and filtering path is configured to amplify and filter a first time division duplex (TDD) uplink (UL) signal or a first TDD downlink (DL) signal in a first frequency range;
• a wireless modem configured to:
• generate an UL/DL indication signal for the first frequency range;
• send the UL/DL indication signal to the repeater;
• identify one or more frequency ranges associated with a plurality of cellular carriers;
• scan the one or more frequency ranges;
• identify monitoring information for the one or more frequency ranges associated with the plurality of cellular carriers;
• and
• provide the monitoring information to the repeater;
• and
• a directional coupler having at least a first port, a second port, and a third port, wherein:
• the first port of the directional coupler is configured to be coupled to the first port of the repeater;
• the second port of the directional coupler is configured to be coupled to a server antenna port of the repeater;
• and
• the third port of the directional coupler is configured to be coupled to the wireless modem;
• and
• the directional coupler is configured to couple a modem signal from the wireless modem with an uplink signal at the repeater first port for communication via an uplink path of the repeater for transmission to a base station.
