a passive optical network coupled to the wireless base station at the central office to provide a link to extend an antenna for wireless operations of the wireless base station to a remote site such that a wireless signal from the wireless base station is transmitted in parallel with a passive fiber network signal through the link, wherein wavelength-division multiplexing is employed to transmit the wireless signal to an area, and sub-carrier modulation multiplexing is employed to distribute the wireless signal to receivers within the area,
wherein the wireless base station transmits gain control and frequency information to the remote site for adjusting a configuration of a power amplifier and a clock synthesizer at the remote site.
2. The network system as recited in claim 1 , wherein the wireless signal is a radio frequency signal.
3. The network system as recited in claim 1 , wherein the wireless signal is an intermediate frequency signal.
4. The network system as recited in claim 1 , wherein the wireless signal is a digitized signal.
5. The network system as recited in claim 1 , wherein the signals are enabled to travel in parallel by employing wavelength-division multiplexing.
6. The network system as recited in claim 1 , wherein network system includes wireline and wireless services simultaneously.
7. The network system as recited in claim 1 , wherein the wireless base station includes an indoor unit at the central office and a plurality of outdoor units disposed remotely wherein the plurality of outdoor units employ a parallel signal detection method to enable a unique sub-carrier for an individual wavelength associated with each of the plurality of outdoor units.
8. The network system as recited in claim 1 , wherein the wireless base station includes an indoor unit at the central office and an outdoor unit disposed remotely from the central office, the network further comprising a distributed antenna network with a given cell.
9. The method as recited in claim 1 , wherein the optical line terminal and wireless base station share a common processor.
10. A method for simultaneously providing wireline and wireless services, comprising:
integrating a wireless base station with an optical line terminal in a single chassis at a central office of a service provider to permit resource sharing between the wireless base station and the optical line terminal, the wireless base station being connected to the optical line terminal through a chassis backplane and sharing a common modulator and receiver with the optical line terminal, wherein the wireless base station is configured to provide portable and fixed services to customers;
coupling a passive optical network to the wireless base station at the central office to provide a link to extend an antenna for wireless operations of the wireless base station to a remote site; and
transmitting a wireless signal from the wireless base station in parallel with a passive fiber network signal through the link, wherein wavelength-division multiplexing is employed to transmit the wireless signal to an area, and sub-carrier modulation multiplexing is employed to distribute the wireless signal to receivers within the area,
