IBS (In-building Solution)

In-building Solutions, IBS, are solutions that provides mobile coverage inside buildings, where the coverage, capacity or quality otherwise would not had been satisfactory. There are several different ways to implement in-building solutions. Dedicated Radio Base Stations, RBSs, that are connected to Distributed Antenna Systems, DASs, are commonly implemented solutions. These solutions provide additional capacity as well as covers “black holes” inside different kinds of buildings. A number of different types of both RBSs and DASs are available and the solutions can be customized for different buildings and needs.
