Abstract: growth of high speed data support to multimegabits

       Abstract:The objective is comprehensive studyrelated to 5G technology of mobile communication. In 5G, researches are relatedto development and evolution of World Wide Wireless Web(WWWW), Dynamic Ad HocWireless Networks(DAWN) and Real Wireless Communication. The most importanttechnologies are Wireless Local Area Networks(WLAN) and Wireless MetropolitanArea Networks(WMAN), Ad-hoc Wireless Personal Area Network(WPAN) and Wirelessnetworks for digital communication.5G technology is independent of othertechnologies. 5th generation mobile networks or 5thgeneration wireless systems, abbreviated as 5G. The next telecommunicationstandards, operating in the millimetre wave.5G planning aims at higher capacity  than 4G, its allowing higher density of mobile broadband users,reliable and massive communication.

5G technology aims at lower latency, lowerbattery consumption and implementation of internet of things. The 5G technologyinclude all types of advanced features. Keywords-WLAN,5G, GSM, WWWW, WMAN, DAWN                                                        IntroductionToday phone has smallest size, large memory, camera, video player, Bluetoothand so on Recently with the development of all we can share files using aBluetooth up to a range of 50 meters. The creation and entry of 5G technologyinto mobile marketplace will launch a new revolution. The future of mobileSystem is largely dependent on the development and evolution of 4G systems.4Gis used independent from other technologies.

With gradual growth of high speeddata support to multimegabits per second, an integration of services willhappen. The transformation changes from 4G systems to 5G include a wireless worldwide web support to have high flexible and changeable ad hoc networks. There areno standards for 5G deploymentThe next mobile technology should fulfil the following requirements: Data rates of tens of megabits per second for tens of thousands of users Data rates of 100 megabits per second for metropolitan areas 1 Gb per second simultaneously to many workers on the same office floor Several hundreds of thousands of simultaneous connections for wireless sensors Spectral efficiency significantly enhanced compared to 4G Coverage improved Signaling efficiency enhanced Latency reduced significantly compared to LTE.Mobile and wireless networks have made remarkable development in thelast few years. In now a days many mobile phones have also a WLAN adapter. One may expect that near soon many mobile phones will have Wax adaptertoo, besides their 3G, 2G, WLAN, Bluetooth etc. We are using IP for bothgenerations.

 Challenges in migration from 4G  Multi-mode user terminals Choice among various wireless systems Security Network infrastructure and QoS support Charging and Billing Attacks on Application Level Jamming and spoofing Data Encryption  5G COMMUNICATIONS SYSTEM:The mobile communications system in 5g willcreate a major change in the way mobile communications networks operate. Thiscan be achieved though 5G new radio and 5G NextGen Core Network.5GNew Radio, 5G NR:  5G new radio is the new name for the 5G radio access network. It consists ofthe different elements needed for the new radio access network. Using a farmore flexible technology the system is able to respond to the different andchanging needs of mobile users whether they be a small IoT node, or a high datauser, stationary or mobile.5G NextGen Core Network: 5G initially utilised the use and support of 3G networks.The major aim of this system is to have a network that can handle larger volumeof data which can support less latency.

 NEED FOR 5G MOBILE COMMUNICATION: 5G has better coverage area and highdata rate at the edge of the cell.It has low battery consumption.Availability of multiple data transferpath.Around 1 Gbps data rate is easilypossible.

Security is more.Energy efficiency and spectralefficiency are good. FUTURISTIC SCENARIOS AND 5G COMPLIANCE: In 2020 thesociety will be connected society. The Internet of thing together will changethe lives people in future generation.

In future people who depend on “Smartliving” will need unchangeable or constant connectivity to the network toupload their day to day activity data and IoT control commands, thus generatinga “massive reporting” uplink data flow. The machine to machine communicationswill a major role in industry operations and service delivery.Vehicular ad-hoc networks (VANETs) are constantly advancing. By 2020,VANETs integrated with cellular networks will be in operation as VANET cloud,leading to a smarter and safer transportation system.When the number of devices connected to the Internet passes tens orhundreds of billions in the coming decade, the offloading of networked data onunlicensed bands will play a critical role in network load balancing, providingguaranteed bit rate services and a reduction in control signaling. Hence, it isimportant that 5G will provide seamless compatibility with dense heterogeneousnetworks to satisfy the high demand of real-time traffic, so that end userswill experience smooth connectivity to the network. JUSTIFICATION: The 5Gtechnology is designed as an open platform on different layers, from thephysical layer up to the application.

Presently, the current work is in themodules that shall offer the best Operating System and lowest cost for aspecified service using one or more than one wireless technology at the sametime from the 5G mobile.
