ultimedia works. CDMA2020 CDMA2020 is a decidedly efficient 3G standard for the delivery of high bandwidth data and high capacity voice services. The evolution of the cdma2020 standard will enable mobile systems to offer data throughputs of 2 Mbit/sec and beyond. The higher bandwidth that cdma2020 provides will deliver the full potential of 3G. For example, cdma2020 also allows simultaneous access to several voice, video and data services at once. CDMA2020 is fully pliant with IMT2020 requirements for 3G. CDMA2020 will be implemented in the existing frequency bands of CMDA and TDMA at 800 and 1900 MHz, as well as in new spectrum at 2GHz in Japan. Ericsson is a leader in cdma2020 development, and a key driver in the standardization of evolutionary phases of the air interface and the backbone works, as well as the migration to ALLIP and multimedia works. Bluetooth Bluetooth is an open standard for twoway, shortwave radio munications between different devices. It marks the end of cables and cords between mobile phones, palmtops, portable PCs and printers, for example. Furthermore, Bluetooth enables information between such devices to be synchronized. Diary information held on a PDA can be updated automatically when within range of a Bluetoothenabled PC. Bluetooth is also going to be important for machinetomachine munications one of the largest growth areas in telemunications. Bluetooth is a key development for terminals and other devices using mobile works. It is available now for 2G works and as 3G systems, will play an increasingly important supporting role in the future of mobile munications. Ericsson has already announced Bluetooth devices, including the T36 Bluetooth phone and a Bluetooth headset. Bluetooth was originally developed by Ericsson, but is now under the auspices of the Bluetooth Special Interest Group. It has widespread support among tele equipment vendors, puter and chip manufacturers. Symbian Symbian is an independent joint venture supported by panies including Ericsson, Nokia, Motorola and Psion. Symbian aims to promote a mass market for mobile information devices in two ways: First, through the development of core software, application frameworks, applications and development tools for mobile multimedia devices (such as PDAs, smartphones and municators) Second, by evangelizing standards for the interoperation of mobile information devices. Symbian39。 s EPOC operating system is already available and Ericsson devices such as the R380 are EPOCenabled. WAP Wireless Application Protocol (WAP) is a global, open standard that gives mobile users access to Inter services through handheld devices. It enables users to easily access a to , Inter access and other serwhole range of Mobile Inter and other data services from mobile devices such as smartphones and municators, and without the need to plug into a separate laptop or dataenabled device. WAP enables this through a builtin WAP microbrowser that lets information be accessed direct from a phone, in the same way that web browsers provide access to online services via an Interready PC. Typically, a WAP screen will display a number of hyperlinks to various services or information portals. As well as WAP phones, Ericsson has also announced a WAP Service Developer39。 s Kit (WapIDE) and the WAP Gateway/Proxy, which bridges WAP applications and services in Inter and intra environments with mobile works. In addition, Ericsson provides application enablers, such as Ericsson Localized Inter (ELI) for locationbased services, and WAP Application Server (WAS) providing a runtime and development environment for WAP applications. Ericsson is one of the four founding members of the WAP Forum. Since 1997, when it was established, the WAP Forum has gained widespread industry support hundreds of panies are members of the worldwide WAP Forum。 The latest version of the WAP standard, WAP , has recently been launched. Our dedicated WAP consutants are ready to assist operators and service providers sharpen their petitive edge. They help today39。 s businesses adapt to the new economy and create costeffective, innovative ways to municate with customers. What will 3G give us People will enjoy the 3G time what services it provide, the image of that, 3G is video conference on that plane。 3G is patients receive timely assistance of medical experts。 3G is fans will not miss the NBA basketball game。 3G is to share with friends your beautiful vacation in Hawaii. more and more 3G video phone All along, we use , MSN chat with friends remotely.
