“Prem Prakash Gupta Institute of Engineering, Bareilly”: User Friendliness User Personalisation USER User Sensitivity “Prem Prakash Gupta Institute of Engineering, Bareilly” NETWORK Presented By: Pragati Gupta B.Tech .-CSE(4 th Sem ) : User Friendliness User Personalisation USER User Sensitivity AGENDA Introduction. 4G Network. Why 4G is invented? Applications of 4G. 4G Access Options. Features of 4G. 3G vs 4G. Drawbacks of 4G. Future Prospects. Which Countries Have 4G? 4G in India. Conclusion. References. 4G 3G 2G 1G Introduction : User Friendliness User Personalisation USER User Sensitivity Introduction 1G Network 2G Network 3G Network 4G Network : User Friendliness User Personalisation USER User Sensitivity 1-G Network Refers to the first-generation of wireless telephone technology, mobile telecommunications. Developed in 1980s and completed in early 1990’s. DRAWBACKS: Poor voice quality. Poor battery life. Large phone size. Poor handoff reliability. : User Friendliness User Personalisation USER User Sensitivity 2G Network Was launched in Finland in the year 1991. enabled services such as text messages, picture messages and MMS.    DRAWBACKS: Requires strong digital signals to help mobile phones work. If there is no network coverage in any specific area, digital signals would be weak. They are unable to handle complex data such as video. : User Friendliness User Personalisation USER User Sensitivity 3G network The 3G technology adds multimedia facilities to 2G phones by allowing video, audio, and graphics applications. 3G networks provide the ability to transfer voice data and non-voice data (music downloads, emails and instant messaging) over the same network simultaneously. DRAWBACKS: 3G Phones are expensive. Huge capital. : User Friendliness User Personalisation USER User Sensitivity 4G Network Characterised by high-speed data rates. In 4G the download speed is up to 100 Mbps for moving users and 1 Gbps for stationary users. Will allow users to download a full-length feature film within five minutes. Will also be able to stream high-definition television and radio to hand-held devices. : User Friendliness User Personalisation USER User Sensitivity Why 4G is invented? 4G 3G 2G 1G High transfer rate. Internet access any where. Ability to move around with the same IP address. High resolution Mobile TV. 4G Applications:  4G Applications Organizational services. Communications services and applications. Entertainment services. Mobile commerce (M-Commerce). User Friendliness User Personalisation USER User Sensitivity : User Friendliness User Personalisation USER User Sensitivity 4G Access Options Embed 4G technology into all end-user devices. Develop external interfaces with 4G peripherals. Features of 4G Network : Features of 4G Network Support interactive multimedia. User friendliness. High speed & high capacity. Network Heterogeneity. User Friendliness n USER User Sensitivity Comparison between 3g and 4g: Comparison between 3g and 4g 3G 3.1MB /sec Broadband Low 5 - 20 MHz 1.6- 2 GHZ Wide Area Network Technology Data Transfer Rate Internet services Mobile -TV Resolution Bandwidth Frequency Network Architecture 4G 100MB/sec Ultra Broadband High 100 +MHz 2 – 8 GHz Hybrid Network : User Friendliness User Personalisation USER User Sensitivity Drawbacks of 4G Battery usage is more. Need complicated hardware. The equipment required to implement a next generation network is still very expensive. Carriers and providers have to plan carefully to make sure that expenses are kept realistic. : User Friendliness User Personalisation USER User Sensitivity Future Prospects 4G is coming quicker. Fast internet access to both stationery and mobile users. 4G can be efficiently combined with cellular technologies to make consistent use of smart phones and also create video blogs . This gives the manufactures the opportunity to produce more affordable user friendly 4G compatible devices . : User Friendliness User Personalisation USER User Sensitivity Which Countries Have 4G? Except for the Scandinavian countries, a few countries have started the 4G commercially. In the US, Sprint Nextel initiated the service last year. Countries expected to launch 4G by this year are Germany, Spain, China, Japan and England. : User Friendliness User Personalisation USER User Sensitivity 4G in INDIA Has already begun the process of introducing 4G. India is among the latecomers in 3G. It has taken three years for the government to decide on 3G-spectrum auction policy. 4G could face the same delay unless India wants to catch up with the rest of the world. Conclusion: Conclusion 4G can be best described in one word “ MAGIC ”, which stands for: M obile m ultimedia. A nytime A nywhere. G lobal mobility support. I ntegrated wireless and personalized services. Customized personal service.
