There are three achievable architectures for 4G. Multimode devices Overlay network Common inlet protocol. Multimode devicesThis architecture uses a single bodily terminal with multiple interfaces to entrance money services on antithetic wireless networks. It whitethorn improve call completion and increase effective coverage area. It should excessively bring home the bacon reliable wireless coverage in case of network, link, or switch failure. The user, device, or network can initiate handoff amongst networks. The device itself incorporates most of the additional complexity without requiring wireless network modification or employing inter working devices. Each network can deploy a database that keeps label of user location, device capabilities, network conditions, and user preferences. Figure-1 The handling of quality-of-service (QoS) issues re main(pren ominal)s an open search question. Overlay networkIn this architecture, a user accesses an sheathing network consisting of several universal access points. These UAPs in turn select a wireless network based on availability, QoS(Quality of Service) specifications, and user defined choices. A UAP performs protocol and frequency translation, content adaptation, and QoS negotiation-renegotiation on behalf of users. Figure-2 A UAP stores user, network, and device information, capabilities, and preferences. The hide network, rather than the user or device, performs handoffs as the user moves from one UAP to another. Common access protocol This protocol becomes viable if wireless networks can can one or two standard access protocols.One possible solution, which will require inter working surrounded by different networks, uses wireless asynchronous transfer mode. To in any casel wireless automated teller, every wireless network must abandon contagious disease of standard atmospher e cells with additional headers or wireless ATM cells requiring changes in the wireless networks. Figure-3 Challenges v 4G rendering A orbiculate consensus on the 4G definition is needed forwards the standardization starts. despite efforts there suave are too many diverge approached to 4G. Seamless connectivity Inter- and intra-network connectivity is perfect to the formulation of temporally and spatially circular-knit services. Vertical and crosswise handovers are decisive for 4G.In the fountain case, the heterogeneity and variety of networks modify the problem. Latency Many 4G services are delay sensitive. Guaranteeing short delays in networks with different access architecture and coverage is utmost from straightforward . 4G definition A global consensus on the 4G definition is needed before the standardization starts. Despite efforts there still are too many diverging approached to 4G . Seamless connectivity Inter- and intra-network connectivity is fun damental to the provision of temporally and spatially broadloom services. Vertical and horizontal handovers are critical for 4G. In the former case, the heterogeneity and variety of networks exacerbate the problem. Development picA Japanese company has been testing a 4G communication system prototype at 100 Mbit/s while moving, and 1 Gbit/s while stakeary. Recently reached 5 Gbit/s moving at 10 km/h, and is planning on purgative the first commercial network in 2010. An Irish company has announced that they have received a mobile communications license from Irish Telecoms regulator. This service will be issued the mobile code 088 in Ireland and will be used for the provision of 4G Mobile communications. Sprint plans to launch 4G services in trial markets by the end of 2007 with plans to deploy a network that reaches as many as 100 million people in 2008 4G mobile technologies ) consecrate Wireless Architecture (OWA) 2) Spectrum-efficient High-speed wireless mobile transmissio n 1. Open Wireless Architecture (OWA) A single system architecture characterized by a horizontal communication model providing common chopine to complement different access technologies in an optimum way for different service requirements and radio environments is called the converged broadband wireless political program or open wireless architecture (OWA). OWA will be the next pull in wireless communications, fueled by many emerging technologies including digital dramaturgy processing, software- definable radio, intelligent antennas. The open wireless platform requires Area and power-efficient broadband channelize processing for wideband wireless applications Highest perseverance channel density (MOPS pooling) in negotiable new BTS signal processing architectures BTS solutions scalable to higher clock rates and higher network capacity Space-Time Coding and MIMO(Multiple-Input-Multiple-Output) Increasing demand for high exercise 4G broadband wireless mobile calls for use o f multiple antennas at both base station and subscriber ends. Multiple antenna technologies enable high capacities suited for cyberspace and multimedia services and also dramatically increase range and reliability.. pic Figure-4 The target frequency band for this system is 2 to 5 GHz due to favorable coevals characteristics and low radio-frequency (RF) equipment cost. AdvantagesSpatial diversity and coding gains for large link budget gains (>10 dB). loss Multiple antennas at the transmitter and rece- iver allow diversity in a attenuation environment. 2. Spectrum-efficient High-speed wireless mobile transmission Wide-area wireless broadband systems spectral ability can yield a system capacity that allows that experience to be delivered at the same time to many users in a cell, simplification the cost of service delivery for this mass-market broadband service. These systems are optimized to exploit the full effectiveness of adaptive antenna signal processing, thereby providin g robust, high-speed connections for mobile users with a stripped-down of radio infrastructure. cut back spectrum requirements, minimizing up-front capital expenses related to spectrum Reduced infrastructure requirements, minimizing capital and operating be associated with base station sites, translating into reduced be per subscriber and per covered population division The acquisition of spectrum is a key section of the cost structure of wireless systems, and two key features of spectrum have great concern on that cost ( the spectral faculty of the wireless system and the type of spectrum essential to implement the system. A fully capable and commercially viable mobile broadband system can operate in as little as 5 MHz of unpaired spectrum with a numerate of 20 Mbps throughput per cell in that come in of spectrum.Factors contribute to the spectral efficiency of a system 1)Modulation formats, Air interface knock 2)Multiple access method, Usage model. The quantities just mentioned all contribute to the bits/second/Hertz dimensions of the unit. The style of a per cell dimension may seem surprising, but the throughput of a position cells base station in a cellular network is almost always substantially less than that of a single cell in isolation. Future of 4G The future of wireless is not just wireless, it is a part of life. The future furnishs faster speeds and larger bandwidth. It is suggested that 4G technologies will allow 3D virtual reality and interactive video / hologram images.The technology could also increase interaction between compatible technologies, so that the smart railcard in the handset could automatically pay for goods in passing a linked recompense kiosk (i-mode can already vaunting this capability) or will tell your car to warm up in the morning, because your audio has noted you have left the house or have set the alarm. 4G is judge to provide high-resolution images (better quality than TV images) and video-links (all o f these will require a band width of well-nigh 100MHz). Conclusion ? From user driven perspective, the user has freedom and flexibleness to select the service, at a fair QoS and price, anytime, anywhere Reconfigurability Next-generation wireless network interfaces need to be able to switch seamlessly between different communications standards, in run to provide the most suitable train of service while the user moves across different environments. ? 4G, convergence of networks, technologies, applications and services, will offer a personalized and pervasive network to the users. ? Convergence is heading towards an advent of a really exciting and disruptive construct of 4th generation mobile networks.
