Covering system architecture, implementation and testing, this work is written by authors who are widely experienced with cellular radio in general and with GSM in particular. It provides a structured overview to help make sense of the GSM specifications and surveys competing cellular systems such as NADC and CDMA. Practical testing applications are explored in depth and compared with similar techniques used with analogue cellular systems.
The GSM network is amazing by itself. Although the new air interfaces now use more spectrum-efficient codification schemes, the overall network is just about the same. Concepts as reuse factor, soft handover, hard handover, Home Location Register, MS, and so on still apply. If you know GSM well, getting familiar with a new air interface proposal is just a matter of seeing how it implements the old GSM solution: The network architecture is the same. By the way, the part of long-term and short-term prediction for the human voice, just like the noise simulation, is incredible (I won't spoil :p ).
