Abstract: The subject matter discloses at a single site (a site with a single base station), connecting a distributed antenna to a Radio Unit (RU) of a 4G/5G base station such that the antenna elements are deployed at the target area apart from each other. According to some embodiments the RU receives from each antenna element a replica of the radio signal that is transmitted by the end terminal. The RU processes the phase differences between the subcarriers of each pair of signal replicas which are received by the antenna elements. The RU calculates the DToA (Difference in Time of Arrival) per each pair of replicas of the received signal according to the phase difference. The location measurements of the end terminal are carried out by performing triangulation using the DToA measurements.
