Abstract
Various methods, apparatuses, and systems are described in which a WAP is coupled to an antenna unit and provides a wireless LAN. In one embodiment, the antenna unit includes at least one remote antenna circuit having one or more ports to receive a control signal and a transmit signal transmitted from the WAP located in a multi-tone transmitter-receiver. Each remote antenna circuit includes a transmit amplifier unit that amplifies the transmit signal, a receive amplifier unit that amplifies a receive signal, and control unit that receives the control signal. The control unit controls an operation of the transmit and the receive amplifier units to extend a range of the wireless WAP with the at least one remote antenna circuit.
Claims20
An antenna unit comprising:
- one or more remote antenna circuits having one or more ports to receive a control signal and a transmit signal transmitted from a wireless access point located in a multi-tone transmitter-receiver, each remote antenna circuit having a transmit amplifier unit to amplify the transmit signal, a receive amplifier unit to amplify a receive signal, and control unit to receive the control signal, the control unit to control an operation of the transmit and receive amplifier units to extend a range of the wireless access point with the at least one remote antenna circuit.
A system comprising:
- a network interface device (NID) having a wide area network communication gateway with an wireless access point that has a first frequency converter to convert a transmit signal with a first frequency band into a second frequency band;
- an input to receive the transmit signal from a digital subscriber loop access multiplexer with the transmit signal carried across a public telephone network to the NID;
- and
- one or more ports of the wireless access point to transmit the transmit signal to at least one antenna circuit coupled to the wide area network communication gateway via a coaxial cable, one or more ports of each antenna circuit to receive the transmit signal from the one or more ports of the wireless access point and to convert the second frequency band into the first frequency band with a second frequency converter, an antenna of each antenna circuit to receive a receive signal with the first frequency band and to convert the first frequency band into a third frequency band with a third frequency converter, the receive signal is sent to the wireless access point, the second and third frequency bands are selected to minimize the attenuation of the transmit and receive signals between the wireless access point and each antenna circuit.
A method comprising:
- sending a control signal and a transmit signal from an wireless access point to at least one remote antenna circuit with each remote antenna circuit having a transmit amplifier unit to amplify the transmit signal, a receive amplifier unit to amplify a receive signal, and control unit to receive the control signal, the control unit to control the operation of the transmit and receive amplifier units to extend a range of the wireless access point;
- and
- sending the receive signal from each remote antenna circuit to the wireless access point located in a multi-tone transmitter-receiver.
An apparatus, comprising:
- means for sending a control signal and a transmit signal from a wireless access point to at least one remote antenna circuit via a coaxial line with each remote antenna circuit having a transmit amplifier unit to amplify the transmit signal, a receive amplifier unit to amplify a receive signal, and control unit to receive the control signal;
- means for determining an amount of control signal loss from transmission of the control signal over the coaxial line;
- means for adjusting a gain of at least one of the transmit amplifier unit and the receive amplifier unit located in the remote antenna circuit in response to the determination of the amount of the control signal loss;
- and
- means for sending the receive signal from each remote antenna circuit to the wireless access point located in a multi-tone transmitter-receiver.
