Mobile phone base stations transmit and receive these calls - and connect callers to other phones and other networks.The size of a cell depends on the area of coverage that’s needed and the number of calls that are made in that area. So, the smallest cells, i.e. more base stations, are where there is the biggest demand which is usually in crowded urban settings with high buildings and heavy population density, but the biggest cells tend to be in rural areas, where people are dispersed over a wider, less built up, area.When a mobile phone caller is on the move, calls are automatically routed from a base station in one cell to a base station in another, thus providing the best signal and available capacity.
We ensure that there is an adequate number of base stations in a particular area to reduce the chances of the signal being interrupted or the call 'dropped'.Dropped calls is one of the performance measures used by the regulator to measure the quality of our network, which is used to carry our customers' calls.
