Abstract

In order to satisfy the requirements and expectations of the users to have more advanced wireless communication in mobile environments, this paper outlines the technical issues involved in Beyond Third Generation (B3G) mobile communications, highspeed large capacity transmission capability is an essential requirement for B3G mobile communications for which we suggest VSF-OFCDM (SCS-MC-CDMA, OFDMA and IFDMA) efficient modulation demodulation techniques to achieve higher spectral utilization efficiency (such as combination of OFDM with CDMA, error control coding using LDPC codes). All CDMA systems suffer from interference-limited capacity, which significantly reduces the number of simultaneous mobile users in the system. To overcome the interference-limited problem (OFDM with VSF is the solution). We carefully (focus) study on the development of Wireless Networks (WWAN, WLAN and WPAN) which completely depends on frequency allocation. And we shown how these two are (wireless networks and frequency allocations) correlated to build up mobile evolution in Europe. We have estimated and analyzed the trend in uptake of mobile subscribers worldwide for 2G, 3G and B3G cellular systems considering the number of services provided based on wireless networks and frequency allocation to accommodate large number of users. Finally we explain B3G developments and some future mobile communications systems
