APPARATUS AND METHOD FOR MEASURING TRAFFIC OF USERS IN A BUILDING USING DISTRIBUTED ANTENNA SYSTEM

摘要

A current mobile communication network service provider uses a distributed antenna system connected by an optical fiber to efficiently provide coverage in a building of a large scale. At the time, since one cell provides a service with respect to a plurality of layers inside the building, a user of a specific layer and distribution of traffic can not be known. A base station applies a different virtual delay for each of a plurality of distributed antennas located in each layer to measure the traffic to know a layer where a terminal is located through a timing advance value of the terminal.
