Abstract
Provided are an apparatus, system, and method for facilitating wireless communication between a hub and a mobile terminal via a remote radio module. The remote radio module includes a first transceiver operable to wirelessly communicate with the mobile terminal, a second transceiver operable to wirelessly communicate with the hub that is coupled to a core network, and a processor for executing instructions stored in memory. The instructions include instructions for receiving a signal from the hub at a first carrier frequency and processing the signal so that the signal can be retransmitted to the mobile terminal at a second carrier frequency different from the first carrier frequency.
Claims20
An apparatus comprising a remote radio module for facilitating wireless communication between a hub and a mobile terminal in a wireless network, the remote radio module including:
- a first transceiver operable to wirelessly communicate with the mobile terminal;
- a second transceiver operable to wirelessly communicate with the hub that is coupled to a core network;
- and
- a processor for executing instructions stored in memory, the instructions including instructions for:
- receiving a signal from the hub at a first carrier frequency;
- and
- processing the signal so that the signal can be retransmitted to the mobile terminal at a second carrier frequency different from the first carrier frequency.
The apparatus of claim 9, wherein the signal includes an OFDM modulated signal having a plurality of tones;
- and
- wherein the instructions further includes instructions for utilizing one or more of the tones for an Operational, Alarm, and Monitoring (OA&M) control channel between the hub and the remote radio module, the one or more tones being reserved for non-traffic data as specified by the one of the standards using an OFDM carrier.
A wireless communication system, comprising:
- a hub coupled to a core network;
- and
- a plurality of remote radio modules, each remote radio module including:
- a first transceiver operable to wirelessly communicate with a mobile terminal;
- a second transceiver operable to wirelessly communicate with the hub;
- and
- a processor for executing instructions stored in memory, the instructions including instructions for:
- receiving a signal from the hub at a first carrier frequency;
- and
- processing the signal so that the signal can be retransmitted to the mobile device at a second carrier frequency different from the first carrier frequency.
A method for facilitating wireless communication between a hub and a mobile terminal via a remote radio module, the method comprising:
- providing the remote radio module having a first transceiver operable to wirelessly communicate with a mobile terminal and a second transceiver operable to wirelessly communicate with the hub;
- receiving a signal from the hub at a first carrier frequency;
- and
- processing the signal so that the signal can be retransmitted to the mobile terminal at a second carrier frequency different from the first carrier frequency.
