The demand for greater flexibility both in bandwidth allocation as well as in geographical terms has opened up the new application area of Wireless Local Loops (WLL). WLL provide a telephone system where subscribers are connected to the Public Switches Telephone Network (PSTN) using radio signals rather than copper wire for part or all of the connection between the subscriber and the switch.
Divided into two parts, theoretical aspects and applications, Wireless Local Loops brings together contributions from leading world experts in this increasingly important section of wireless communication systems.
- Covers all aspects of WLL from design to implementation.
- Explains the theoretical aspects of WLL including areas such as propagation, modulation, coding, channel modelling and also traffic engineering issues.
- Presents the applications areas of WLL including interference, prototype designs of various access protocols, a mobility manager, a remote management systems and the provision of multimedia services.
By providing a self-contained treatment of the progressively important area
Wireless Local Loops will have immense appeal to practising engineers, researchers and graduate students needing to understand the bakground to WLL and its major role in the provision of new services.
This book entitled Wireless Local Loops - Theory and Applications has bcen motivated by a similar course taught by the editor and by a conference on a similar subject organised by the same editor. The aim of the book is to present in a self-contained inamer and in a tutorial format the theoretical aspects and various practical applications of a new medium of transmission which is called Wireless Local Loops which is making a major impact iii the provision of new services. Over the years, WLL have bcen called
radio in the loop (RITL) or
fixed radio access (FRA) to indicate a system that connects subscribers to the pubZic switched tekphone network (PSTN) using radio signals as a substitute for copper for all or part of the connection between the subscriber a d the switch. This includes cordless access systems. proprietary fixed radio access, and fixed cellular systems.
