1. Background information Wireless and mobile communications is one of the fastest growing areas of modern life. It has an enormous impact on almost every aspect of our daily lives. A world of ubiquitous wireless devices is emerging, from wireless sensors and tags to mobile terminals. There are a number of wireless systems and networks in operation such as GSM, GPRS, EDGE, UMTS, IEEE 802.11, and Bluetooth, and several multiple access techniques including MC-CDMA, W-CDMA, and OFDM are used. Long-range cellular communication encompasses the evolution from GSM to 3G systems. It aims to achieve full mobility and global roaming for individual links maximizing system capacity. In short-range wireless networking and wireless connectivity, WLAN or PAN covers local hot spot areas for very high data rate asymmetric individual links (e.g. IEEE 802.11, HIPERLAN). Also fixed wireless local loops provide wireless access from street to home for broadband internet and multimedia services.[1]
