Base Transceiver Stations (BTS) require precise timing, particularly 4G/LTE networks and Distributor Antenna Systems (DAS). Where a BTS is remotely located to the timing antenna, such as in a metropolitan area, RF over fibre can be used to connect the antenna to the BTS. RF over fibre is also an ideal solution for subway/underground, government and defence buildings or in DAS applications. Ideal for multiple base stations and limited roof space for GPS antennas, RF over fibre allows the possibility of using one antenna with the signal converted to light and then optically split to multiple locations (2-200).
GNSS driven network time servers also require an accurate time signal. If the location of a time server is not near a building roof or no copper is allowed into the building, RF over fibre is an ideal solution for the GNSS connection. Equally when there are multiple time servers in different locations/floors, RF over fibre can be split across multiple floors.
