Once all the fundamentals of indoor wireless communications have been studied in the previous chapters, it is time to start practising the design of various in-building radio systems using practical design scenarios. This chapter aims at integrating theory with practical considerations that should be made for designing and installing wireless networks inside buildings, presented as case studies for various types of environments.

11.1 Public Venue

As mobile phones become more affordable, subscriber usage patterns continue to evolve. The second generation (2G) of mobile telephony primary focus was making voice calls on the move; third generation (3G) focus was on accessing emails and sending short text messages while being away from a desk.
