Introduction• Now-a-days the goal of many customers is to have PC at one’s palm.• To support such powerful systems we need long range, high speed wireless network called 4G.
About 4G !#is the fourth generation of cellphone mobile communications.#A 4G system provides mobile ultra-broadband Internet access.#A 4G system does not support traditional circuit-switched telephony service, butall-Internet Protocol (IP) based communication such as IP telephony
¿ What is 4G ?4G is a fully IP-basedintegrated system as shownin Fig-1. This will beachieved after wired andwireless technologiesconverge and will becapable of providing 100mbps and 1 gbps speedsboth indoors and outdoors,with premium quality andhigh security .
Comparison between 3G & 4G : 3G Network 4G Network• Circuit switching and • Fully packet switching packet switching technology is used. technology is used. • Frequency band 2-8 GHz.• Frequency band 1.8-2.5 GHz. • Data transfer rate 20 mbps• Data transfer rate 2 mbps and more. and more. • Peak download rate• Peak download rate 1Gbps. 100Mbps. • Peak upload rate 500Mbps.• Peak upload rate 50Mbps. • Data through output up to• Data through output up to 100 to 300 mbps. 3.1 mbps.
EVOLUTION The first commercial deployment was by Telia Sonera and NetCom. Telia Sonera branded the network “4G”. The modem devices on offer were manufactured by Samsung (dongle GT- B3710). The network infrastructure were created by Huawei (in Oslo) and7/14/2012 7:27:09 PM Ericsson (in Stockholm). 12
4G IN INDIA Has already begun the process of introducing 4G India is among the latecomers in 3G. It is felt that by the time the implement 3G fully, 4G technologies such as LTE will be available commercially. It has taken three years for the government to decide on 3G-spectrum policy.7/14/2012 7:27:09 PM 4G could face the same delay unless India 13 wants to catch up with the rest of the world.
4G network in India• In India on 10 April 2012, Indias telecom company Bharti Airtel has launched Indias first 4g services in Kolkata using TD-LTE technology. Its only 14 months back before the official launching in Kolkata when a group consisting of China Mobile, Bharti Airtel and SoftBank Mobile came together, called GTI (Global TDLTE Initiative) in Barcelona and they signed the commitment towards-LTE (Time-Division Long- Term Evolution) standards for the Asian region.
SERVICES PRIOR TO 4G LTE[Long Term Evolution]—UMTS(universal mobile telecomm. Systems) Objectives : Improving Efficiency. Lowering Costs. Improving Services. Better integration with other standards. Aim of LTE : Download rate - 100mbps Upload rate-50 mbps.
WIMAX [Worldwide Interoperability for Microwave Access] Objective: Low Cost. Low Expense Voice transport and delivery of services. Aim: Download data-rate 46 mbps. Upload data-rate 14 mbps. Wi-Max Tower & Reciever
4G Possibilities 4GEnhanced Mobile GamingExperience enhanced wirelesscapabilities that deliver mobilegaming interaction with latencyless than five milliseconds.Play online multiplayer gameswhile traveling at high speedsor sitting outside.
4G Possibilities 4G Personal Media Repository3G Create a personal media repository that can be accessed from home and on2G the road to view photos, watch movies and listen to1G your personal music collection. 0G
4G Possibilities 4G •Broadband Access in Remote Locations 3G 4G networks will provide a wireless2G alternative for broadband access to residential and business customers. In addition, 4G will provide the first1G opportunity for broadband access in remote locations without an infrastructure to support cable or DSL0G access.
4G Possibilities 4G •Virtual Presence 3G Use hologram-generating virtual reality programs that provide an artificial presence just about anywhere.2G For example, decide if you want to personally respond when someone1G rings your front door while you are away from home.0G
CONCLUSION4G mobile phone technologypromises fastercommunication Speeds ,capacity and diverse usageformats.These formats would providericher content and support forother public networks such asoptical fibre and wirelesslocal area networks.
