Abstract
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.
