Implementation of all wireless internet services for 4G mobile communication system
Abstract
Fourth generation (4G) mobile systems and services will mainly be characterized
by a horizontal communication model, where different access technologies such as
cellular, cordless, wireless local area network (WLAN), short-range connectivity,
and wired systems will be combined on a common platform to complement each
Other optimally for different service requirements and radio environments. To
access different wireless networks, multimode user terminals are essential. The
most promising way of implementing multimodal user terminals is to adopt the
software radio approach. The current software radio technology does not meet the
requirements of different wireless networks; because it is impossible to have just
one antenna and one LNA (Low Noise Amplifier) to serve the wide range of
frequency bands.
In this paper, I am implementing a novel idea using CI/OFDM (Carrier
Interferometry-OFDM) to access multiple networks using a wireless terminal.
The physical size of the wireless terminal proposed in the present work, will be
smaller than the terminal with software radio device, and enough memory can be
inserted in the terminal device to store software for all networks.

Willie W.Lu,”Next generation communication towards open wireless standard and software defined radio” IEEE 2008 IET International Conference on Wireless, Mobile and Multimedia Networks
To achieve high data rates in next generation communication systems beyond 3G up to 100 Mbps or more research focuses on the open distributed wireless communication system called ODWCS which is a new architecture for a wireless access system with distributed & smart antennas (MIMO), distributed processors and distributed controlling through software defined radio (SDR) which is supposed to take care of all types of mobility management for end to end quality of service with greater reliability. This paper contributes towards the importance of open communication platform with reconfiguring ability with the changing environment of the communication with the aid of software defined radio. SDR provides an efficient and comparatively inexpensive technique for multi-mode, multi-band, multi-functional communications with software upgrades. SDR technology and open standards promise to do for the wireless industry what the PC and object-oriented software and operating systems have done for the computer industry. |
