    4G Technology Beyond 3G

    Abstract - This paper defines thetechnology beyond 3G, examines the leading4G technologies, and discuss their variousfeatures, benefits and the progress oftechnology to date. It concludes with arecommendation for companies consideringfuture 4G deployments.

    Keywords -4G Technology, Wimax, LTE,4G Network Environment.

    I. INTRODUCTION

    Fourth-generation wireless abbreviated as4G, is a technology that will bringrevolution in wireless communications. Itis also known as beyond 2G and 3G,"

    since it provides a secure IP (InternetProtocol) solution, high data rate of 100Mbps between any two points in theworld, seamless connectivity allowingusers to enjoy global roaming acrossmultiple networks, and support for highquality multimedia.

    Users will enjoy high quality streamingvoice and data at a much higher speedthan 3G. In todays world there is risingdemand of being able to communicate topeople and have access to dataregardless of location. This requirement isbeing fulfilled by 4G.

    The anytime, anywhere solution of 4Gtechnology is also referred to as MAGIC,which is an abbreviation for mobilemultimedia; anytime/anywhere; globalmobility support , , Integrated wirelessand Customized personal service willprovide a wide variety of new services

    including HD video (high definition video),and high quality voice and high-data-ratewireless channels. 4G technology will notonly be used for cellular telephonesystems, but will also be used in wirelessbroadband access communicationsystems.

    Fourth generation networks are likely to use acombination of WiMax and WiFi.Coretechnologies employed by 4G may includeSDR (Software-defined radio) receivers, OFDM

    (Orthogonal Frequency Division Multiplexing),OFDMA (Orthogonal Frequency DivisionMultiple Access), MIMO (multiple input/multiple

    output) technologies, UMTS and TD-SCDMA. All of these delivery methodsensures high rates of data transmissionand packet-switched transmisionprotocols. While 3G technologies, are amix of packet and circuit-switchednetworks.

    A Japanese

    company, NTT DoCoMo, is testing 4Gcommunication at 100 Mbps for mobileusers and up to 1 Gbps and plans onreleasing their first commercial network in2010. Other telecommunicationscompanies, however, are moving into thearea even faster. In August of 2006, SprintNextel announced plans to develop anddeploy a 4G broadband mobile networknationwide in the United States usingWiMAX.

    technologies are commonly (and unofficially)named as higher andhigher variants of 3G such as 3.5G and 3.9G.

    The different 3G technologiesuse more or less the same repertoire of toolswith differentcombinations and variations to optimize

    bandwidth usage.

    IV. CHARACTERISTICSOF 4G

    4G mobile systems will be given by ahorizontal communication model, wherecellular, cordless, wireless LAN type systems,short-range wireless connectivity, and wiredsystems will be combined on a similarplatform to complement each other in thebest possible way for different servicerequirements and radio environments. Thevarious characteristics of 4G technology areas follows :

    4G provides convergence serviceswhich means that the creation of high-reliable and quality broadband mobile

    communication service and ubiquitousservice through wired and wirelessconvergence networks without the spaceproblem and terrestrial limitation, by meansof ubiquitous connectivity.

    4G service will give broadbandservices an advantages of low cost facilityand wide coverage area as compared to theexisting services.

    All-IP technology networking and IPmultimedia services are the importantaspects inthe wired and wireless network. The conceptbehind the broadband convergence network(BcN) fit in the provision of a common,unified, and flexible service architecture

    that can support multiple types of servicesand management applications overmultiple types of transport networks.

    An important issue in security designsfor 4G networks is flexibility.

    To support multimedia services, high-datarate services with good systemreliability will be provided. At the same time,a lowdata rate transmission cost will bemaintained. In order to meet the demands ofthese diverse users, service providers should

    design personal and customizedservices for them. Personal mobility is aconcern in mobility management.Personal mobility concentrates on themovement of users instead of usersterminals, and involves the provision ofpersonal communications andpersonalized operating environments.

    V.ANALYSISOF 4G

    Considering 4G characteristics we canfind out benefits and opportunities of 4Gwith betterunderstandings. The lists and findings follow:Benefits in 4G:- 4G visions take into account installed baseand past investments

    - Strong position of telecommunicationsvendors expected in the marketplace.- Faster data transmission and higher bit rateand bandwidth, allow morebusiness applications and commercialization- Has advantage for personalized multimediacommunication tools

    Opportunities in 4G:- Evolutionary approach may yieldopportunities for the 4G- Emphasis on heterogeneous networkscapitalizes on past investments- Strategic alliance and coalitionopportunities with traditionalnontelecommunicationindustries- Sophisticated and maturecommercialization of 4G technology wouldencourage more applications of e-commerceand m-commerce- Worldwide economy recover stimulatesconsumption and consumerconfidence, therefore bring in opportunitiesfor telecommunication sections- It is expected and predicted thatconsumers will continue to replace handsetswith newer technology at a fast rate.- Desirable higher data capacity rates, thegrowth opportunity for 4G is very bright andhopeful.

    VI. CONCLUSIONFuture wireless networks will need to supportdiverse IP multimedia applications to provideflexibility by allowing sharing of resourcesamong multiple users. The fourth generationpromises to fulfill the goal of MAGIC -a visionthat provides high data rates everywhereover a wireless network.4G technologies are extensions of what weare just beginning to see today in mobileWiMAX and in LTE.With 802.16e WiMAX deployments alreadylaunched worldwide, LTE proponents have jumped uptheir efforts to speed up development, so they are notleft behind.
