摘要： A base station includes an antenna, a radio transceiver, an optical splitter, an optical-to-electrical converter, and a computation module. The antenna may be mounted to a tower and may be configured to receive an RF signal. The radio transceiver may be coupled to the antenna and mounted near the top of the tower. The transceiver may be configured to convert the RF signal to a baseband signal for transmission over a fiber optic link as a first optical signal. The splitter may be configured to split the first optical signal, received via the fiber optic link, into a second optical signal and a third optical signal. The optical-to-electrical converter may be configured to convert the second optical signal into an electrical digital signal including in-phase and quadrature (I/Q) data. The computation module may be configured to compute, based on the I/Q data, signal measurements for location of a mobile station.

摘要： A passive fiber optic repeater bypass is provided which brings fault tolerance to repeatered fiber optic transmission systems. A fiber optic bypass provides an alternate signal path around failed repeaters. The bypass optical attenuation is set to ensure the bypass signal is sufficiently small so as not to interfere with the locally regenerated and transmitted signal, but sufficiently large to be received at the next repeater. In the event of a repeater failure, a repeater monitor disables the local laser transmitter allowing the bypass signal to be received at the next repeater.
