  2. Introduced in 1980s & completed in early 1990s. Analog cellular mobile,Data speed up to 2.4kbps. 1G mobiles- AMPS,NMT,TACS. AMPS first launched by US & it is 1G mobile system. Uses FDMA technique with 30KHz. Allows users to make voice calls in 1 country.
  3. Introduced in late 1980s & finished in late 1990s. Digital cellular systems that are used today. Voice transmission with digital signal. Digital modulation schemes- TDMA,CDMA. Data speed in 2G is up to 64kbps. During the second generation, the mobile telecommunications industry experienced exponential growth in terms of both subscribers and value-added services.
  4. Generation between 2G and 3G. 2.5G networks, such as General Packet Radio Service (GPRS), are an extension of 2G networks . In this they use circuit switching for voice and packet switching for data transmission resulting in its popularity since packet switching utilizes bandwidth much more efficiently.
  5. In this system, each user’s packets compete for available bandwidth, and users are billed only for the amount of data transmitted. Failure in bringing any new evolution . Data speed in 2.5G is up to 144kbps. GPRS, EDGE and CDMA 2000 were 2.5G technologies.
  6. 3G technology is intended for true multimedia cell phone. 3G networks were proposed to eliminate many problems faced by 2G and 2.5G networks, especially the low speeds and incompatible technologies such as Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA) in different countries. Speeds from 125kbps-2Mbps.
  7. In theory, 3G should work over North American as well as European and Asian wireless air interfaces. In reality, the outlook for 3G is not very certain. Part of the problem is that network providers in Europe and North America currently maintain separate standards’ bodies (3GPP for Europe and Asia; 3GPP2 for North America).
  8. The standards’ bodies have not resolved the differences in air interface technologies. There is also a concern that in many countries 3G will never be deployed due to its cost and poor performance. Although it is possible that some of the weaknesses at physical layer will still exist in 4G systems, an integration of services at the upper layer is expected.
  9. Performance in computer networking (WCDMA, WLAN Bluetooth) & mobile devices area (cell phone & GPS). Access to Global Roaming & Clarity in voice calls, Fast Communication, Internet, Mobile T.V, Video Conferencing, Video Calls, (MMS), 3D gaming etc .
  10. The future of mobile systems is largely dependent upon the development and evolution of 4G systems, multimedia networking, and upto some extent, photonic networks. It is expected that initially the 4G mobile systems will be used independent from other technologies. high-speed data access. high quality streaming video. combination of wi-fi and wi-max. Smooth global roaming with lower cost.
  11. In addition, developments in photonic switching might allow mobile communication on a completely photonic network using Wavelength Division Multiplexing (WDM) on photonic switches and routers. These technology arrival in 2010 –2015. SDR,OFDM,OFDMA and MIMO.
  12. The evolutionary view of 4G systems to 5G includes a support of wireless World Wide Web allowing a highly flexible and reconfigurable dynamic networks. 5G is a packet switched wireless system with wide area coverage and high throughput. Complete wireless communication with almost no limitation. Advanced features: powerful and in huge demand in future.
  13. 5G wireless uses OFDM and millimeter wireless that enables data rate of 20 mbps and frequency band of 2-8 GHz. 5G is going to be a packed based network. Faster data transmission that of the previous generations. Multi-Media Newspapers, watch T.V programs with the clarity as to that of an HD T.V. large phone memory, dialing speed , clarity in audio and video etc.
  14. World Wide Cellular phones Extra ordinary data capabilities High connectivity Bright future Flexible channel bandwidth between 5 and 20MHz, optionally up to 40MHz. Data rate of at least 1Gb/s between any two points in the world. Increase system efficiency up to 3 bit/s/Hz/cell in the downlink and 2.25 bit/s/Hz/cell for indoor usage.
  15. 5G terminals will have software defined radios. New error-control schemes. Access to different wireless technologies. Combine different flows from different technologies. Choice among different wireless/mobile access. Network providers for a given service.
  16. Table 1: Comparison of 1G-5G Technologies
  17. High resolution, bi-directional large bandwidth shaping. Advanced billing interfaces: attractive and effective. Subscriber supervision tools for fast action. High quality services based on Policy to avoid error. Large broadcasting of data (GB) supports almost 65,000 connections. Transport class gateway with unparalleled consistency. More accuracy by traffic statistics. Remote management :better and fast solution. Remote diagnostics 1Gbps connectivity speed. Virtual private network.
  18. All delivery service out of business prospect. High uploading and downloading speed  enhanced and available connectivity just about the world. High speed, high capacity, and low cost per bit. Support interactive multimedia, voice, streaming video, Internet and other broadband services. Global access, service portability, and scalable mobile services. Through remote management offered by 5G technology a user can get better and fast solution.
  19. Wearable devices with AI(Artificial Intelligence) capabilities. Global Network. Media independent handover. Radio resource management. VoIP(Voice Over IP) enabled devices. With 6th sense technology.
  20. A new revolution of 5G technology will going to tough competition to normal computers and laptops whose market value will be affected. The coming up 5G technology will available in the market in affordable rates, high peak future and much reliability than its preceding technologies. 5G can serve as a flexible platform and wireless carriers have an opportunity to shorten investment return, improve operating efficiency and increase revenues. Nowadays we are using 2G and 3G technologies and 4G technologies will coming soon, but in future we will want to ready to face 5G technologies and its some features.
