2.1 INTRODUCTION This chapter is concerned with technological issues and it must be said immediately that there are no universally accepted deﬁnitions relating to many of the issues discussed below. We choose to refer throughout to ‘mobile’ communications in order to contrast this with ﬁxed-wire communications, but it is immediately evident that the latter can possess an element of mobility if a handset can be detached from a cradle and carried around the house. Equally, no network can be entirely mobile. If, for example, one wanted to call a number in France from England then the call would have to cross the channel either via an underwater link or via a satellite link. Finally, it is possible for a network to be created using ﬁxed short-range transmitters, probably within the bounds of a city, which allows mobility only within the deﬁned area. The terms ‘wireless’ and ‘cellular radio’ are often used in describing networks that permit full mobility, but these are treated for the purposes of this book as synonyms for ‘mobile’. Hence, the mobile communications market is taken as encompassing services that are provided by connecting two or more mobile devices or terminals via a base station. For the purposes of the discussion below, these devices will for the most part be taken to be handsets since they dominate current usage, although they are constantly evolving both in form and function – Motorola, for example, has taken to referring to ‘the device formerly known as the cell phone’....
