These limits lead to the existence of several types of cell. Macrocells provide wide-area coverage in rural areas or suburbs and have a size of a few kilometres. Microcells have a size of a few hundred metres and provide a greater collective capacity that is suitable for densely populated urban areas. Picocells are used in large indoor environments such as offices or shopping centres and are a few tens of metres across. Finally, subscribers can buy home base stations to install in their own homes.

In a mobile communication system, C is the maximum data rate that one cell can handle and equals the combined data rate of all the mobiles in the cell. 7, using bandwidths of 5, 10 and 20 MHz. 7. The first, and the most important, is the use of smaller cells. In a cellular network, the channel capacity is the maximum data rate that a single cell can handle. 1. The second technique is to increase the bandwidth. Radio spectrum is managed by the International Telecommunication Union (ITU) and by regional and national regulators, and the increasing use of mobile telecommunications has led to the increasing allocation of spectrum to 2G and 3G systems.

In a medium-sized country like the United Kingdom, a typical mobile phone network might contain several thousand base stations altogether. The word cell can be used in two different ways [2]. In Europe, a cell is usually the same thing as a sector, but in the United States, it usually means the group of sectors that a single base station controls. We will stick with the European convention throughout this book, so that the words cell and sector mean the same thing. Each cell has a limited size, which is determined by the maximum range at which the receiver can successfully hear the transmitter.
