Method and system of implementing a radio network in unlicensed spectrum

A system for providing wireless communication services, the system comprising:

• a femto cell communicating over the unlicensed frequency band;
• and
• a mobile switching center (MSC) adapted to communicate over an unlicensed frequency band and over a licensed frequency band;
• wherein the MSC is adapted to communicate with the femto cell over the unlicensed frequency band.

A system for providing wireless communication services, the system comprising:

• a femto cell communicating over the unlicensed frequency band;
• and
• a voice over IP (VoIP) switch adapted to communicate over an unlicensed frequency band and over a licensed frequency band;
• wherein the VoIP switch is adapted to communicate with the femto cell over the unlicensed frequency band.

A dual mode wireless device, comprising:

• an antenna module adapted to receive an incoming signal, the incoming signal being either at an unlicensed frequency band or at a licensed frequency band;
• a core processing module to generate an outgoing signal;
• a first mixer module adapted to process the incoming signal from the antenna module at the unlicensed frequency band;
• a second mixer module adapted to process the incoming signal from the antenna module at the licensed frequency band;
• a first modulator to modulate the outgoing signal over an unlicensed frequency band;
• a second modulator to modulate the outgoing signal over a licensed frequency band;
• a femto cell detection module adapted to detect the presence an unlicensed spectrum femto cell;
• and
• a ganged control apparatus adapted to receive a signal from the femto cell detection module and in response to the signal (1) route the incoming signal from the antenna module to the first mixer module, and (2) route the outgoing signal from the core processing module to the first modulator.

A method of communicating between a dual-mode mobile device and a wireless device, the method comprising:

• providing the dual-mode mobile device, comprising:
• an antenna module adapted to communicate at an unlicensed frequency band and at a licensed frequency band,
• a core processing module to generate an outgoing signal,
• a first mixer module adapted to process the incoming signal from the antenna module at the unlicensed frequency band,
• a second mixer module adapted to process the incoming signal from the antenna module at the licensed frequency band,
• a first modulator to modulate the outgoing signal over an unlicensed frequency band,
• a second modulator to modulate the outgoing signal over a licensed frequency band,
• a femto cell detection module adapted to detect the presence an unlicensed spectrum femto cell, and
• a ganged control apparatus adapted to receive a signal from the femto cell detection module and in response to the signal (1) route the incoming signal from the antenna module to the first mixer module, and (2) route the outgoing signal from the core processing module to the first modulator;
• and
• detecting a presence of the unlicensed spectrum femto cell at the femto cell detection module;
• transmitting a request to establish a connection with the unlicensed spectrum femto cell upon the detection of the presence the unlicensed spectrum femto cell;
• receiving a confirmation signal from the unlicensed spectrum femto cell;
• and
• in response to the confirmation, terminating the connection over the licensed frequency spectrum.
