EJAZ AHMAD AND SUBHENDU DAS WIRELESS SYSTEM A BRIEF VIEW : Generation refers change in nature of Service compatible transmission technology and new frequency bands. 1G systems used analog frequency modulation. 2G systems use digital communication techniques with TDM, FDM, CDMA. 3G systems offer higher data rates and voice and paging services to provide interactive multimedia including teleconferencing and internet access. 4G aims to provide IP telephony, ultra-broadband Internet access, gaming services. A BRIEF VIEW WHAT IS 4G ??? : WHAT IS 4G ??? 4G refers to the fourth generation of cellular wireless standards 4G is a packet switched wireless system with wide area coverage and high throughput. 4G wireless uses OFDM and millimeter wireless that enables data rate of 20 mbps and frequency band of 2-8 GHz. 4G is going to be a packed based network. 4G provide an end-to-end IP solution where voice and data is going to be served to users. 3G Vs 4G The following table shows comparisons between 3G and possible 4G systems. : 3G Vs 4G The following table shows comparisons between 3G and possible 4G systems. OBJETIVES OF 4G : OBJETIVES OF 4G 4G being developed to accommodate QoS rate requirements set by further development of existing 3G applications. Flexible channel bandwidth between 5 and 20MHz, optionally up to 40MHz. Data rate of at list 100Mb/s between any two points in the world. Increase system spectral efficiency of up to 3bit/s/Hz/cell in the downlink and 2.25bit/s/Hz/cell for indoor usage. 4G WIRELESS STANDARD : 4G WIRELESS STANDARD WiMAX formed to provide conformance and interoperability of the IEEE 802.16 standard. It aims to provide wireless data over long distance from point-to-point link to cellular mobile type access. WiBRO a part of IEEE 802.16e in process to provide collaborative and generic mobile WiMAX. 3GPP LTE a project aims to improve the mobile phone standard to cope with future requirements. 3GPP 2 UMB a project to improve the CDMA2000 mobile phone standard for next generation applications. WiMAX NETWORK REFRENCE MODEL : WiMAX NETWORK REFRENCE MODEL IPv6 SUPPORT : IPv6 SUPPORT Unlike 3G, based on two parallel infrastructure circuit switched and packet switched network nodes, 4G will be based on packet switching only. This will require low-latency data transmission. IPv6 support large number of wireless enabled devices. By increasing the number of IP addresses, IPv6 removes the need for NAT (Network Address Translation). Mobility & Information Speed : Mobility & Information Speed BENEFITS OF 4G : BENEFITS OF 4G High speed, high capacity, and low cost per bit. Support interactive multimedia, voice, streaming video, Internet, and other broadband services. Global access, service portability, and scalable mobile services. Better scheduling and call admission control techniques. Smooth handoff across heterogeneous networks. Slide 11: High quality of service for next generation multimedia support (real time audio, high speed data, HDTV video content, mobile TV, etc.) Interoperability with existing wireless standards. In addition to improvements in the multiplexing systems, improved modulation techniques are being used. Whereas earlier standards largely used Phase-shift keying, more efficient systems such as QAM are being proposed for use with the 3GPP Long Term Evolution standards. Regent Technology is assisting potential customers on 4G design and implementation. ADI DSP's are particularly suitable to run 4G engines. Initial prototyping suggests that TigerSHARC can play the main role in 4G hardware architecture. Regent Technology is providing articles on DSP algorithms that will contribute towards successful 4G products. : Regent Technology is assisting potential customers on 4G design and implementation.
