Kurzbeschreibung
WLL (Wireless Local Loop) ist ein Spezialgebiet der Technologie mobiler und drahtloser Kommunikationssysteme mit eigenen Anforderungen und Grenzen. "Wireless Local Loops" erläutert diesen Bereich umfassend und detailliert. Besprochen werden u.a. Analyse und Design, mögliche Dienste und Management von WLLs. Mit Beiträgen führender Fachleute aus Europa, Japan und den USA!
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.
