Broadband Wireless Mobile (3G and 4G) will be the next keydevelopments in wireless communications. Immense interest has beenfuelled by large demand for high frequency utilisation as well as alarge number of users requiring simultaneous multidimensional highdata rate access for the applications of wireless mobile internetand e-commerce. Broadband wireless mobile extends the corporate LANto common areas such as meeting rooms and enables in-buildingpublic wireless hotspots such as airport lounges to providewireless portable computer connectivity. People will be able toaccess information as if they were at their desk and will be ableto communicate reliably and access securely the information mostimportant to them, such as email, corporate data and the Internet.The 3G/4G systems will use a new network architecture (eg All-IPNET) to deliver broadband services in a more generic configurationto mobile customers and supports multidimensional services andemerging interactive multimedia communications. The world oftelecommunications will continue to migrate toward wirelesstechnologies and will ultimately provide users with mobile accessto all types of media and information in a variety of formsincluding media phones and portable computers.
* Provides coverage of 4G mobile - the newest development by ITU(International telecommunication Union)
* Covers range of emerging wireless applications including WAP andiMode
* Provides a world perspective on the topic as the authors are fromUSA, Europe and Japan
An essential reference for engineers and researchers in the fieldof wireless communications systems (and electrical engineering),network planners and operators, as well as a valuable reference forstudents and management, marketing, sales or investor personnel inthe area of wireless communications.
