  3. 3. INTRODUCTION What is 5G technology? 5G Technology stands for 5th Generation Mobile technology. 5G mobile technology has changed the means to use cell phones within very high bandwidth. User never experienced ever before such a high value technology. Nowadays mobile users have much awareness of the cell phone (mobile) technology. The 5G technologies include all type of advanced features which makes 5G mobile technology most powerful and in huge demand in near future.
  4. 4. Generations Of Mobile Network 1G :  system (NMT) was introduced in 1981, It support speed up to 2.4kbps. Major contributors were AMPS, NMT, and TACS.  It has low capacity, unreliable handoff, poor voice links, and no security at all since voice calls were played back in radio towers, making these calls susceptible to unwanted eavesdropping by third parties.
  5. 5. Generations Of Mobile Network 2G :  The second generation of digital mobile phones appeared in 1990s along with the first digital mobile networks  Mainly used for Voice communication and supports speed up to 64kbps  Offered additional services such as SMS and e-mail  Major prominent technologies were GSM, CDMA, and IS95
  6. 6. Generations Of Mobile Network 2.5G :  General Packet Radio Service (GPRS), are an extension of 2G networks  they use circuit switching for voice and packet switching for data transmission  The first full internet service on mobile phones was introduced by NTT DoCoMo in Japan in 1999
  7. 7. Generations Of Mobile Network 3G :  NTT DoCoMo launched the first commercial 3G network on 1 October 2001, using the WCDMA technology  bandwidth of 3G network is 128 Kbps for mobile stations, and 2 Mbps for fixed applications  The current trend in mobile systems is to support the high bit rate data services at the downlink via High Speed Downlink Packet Access (HSDPA) Conti…
  8. 8. Generations Of Mobile Network  provides a smooth evolutionary path for UMTS networks to higher data rates in the same way as Enhanced Data rates for Global Evolution (EDGE) do in Global Systems for Mobile communication (GSM)  It provides an efficient means to share spectrum that provides support for high data rate packet transport on the downlink, which is well adapted to urban environment and indoor applications  Initially, the peak data rates of 10 Mbps may be achieved using HSPDA. The next target is to reach 30 Mbps with the help of antenna array processing technologies followed by the enhancements in air interface design to allow even higher data rates
  9. 9. Generations Of Mobile Network 4G :  launched in November 2011  Use of a higher Layer Protocol (IP) as transport medium affords intelligence at every stage within the network relative to a service  Airtel is using the TD-LTE (Time-Division Long-Term Evolution), which is a variant of LTE developed by China, to provide its 4G services Conti…
  10. 10. Generations Of Mobile Network  4G features: next generation of wireless applications and services, such as e-readers, mobile IPTV, mobile marketing and geo-targeted advertising, location- based mobile applications embedded in social networking are likely to become the key applications in the upcoming 4G apps space
  11. 11. Generations Of Mobile Network
  12. 12. Generations Of Mobile Network
  13. 13. NETWORK ARCHITECTURE  The basic architecture of wireless mobile system consists of a mobile phone connected to the wired world via a single hop wireless connection to a Base Station (BS), which is responsible for carrying the calls within its region called cell  The mobile station communicates via the BS using one of the wireless frequency sharing technologies such as FDMA, TDMA, CDMA etc. Each BS is connected to a Mobile Switching Center (MSC) through fixed links, and each MSC is connected to others via Public Switched Telephone Network (PSTN)
  15. 15. NETWORK ARCHITECTURE  MSC also locates the current cell location of a mobile user via a Home Location Register (HLR) that stores current location of each mobile  the MSC contains a Visitor Locations Register (VLR) with information of visiting mobiles from other cells  The first generation cellular implementation consisted of analog systems in 450-900 MHz frequency range using frequency shift keying for signaling and Frequency Division Multiple Access (FDMA) for spectrum sharing Conti…
  17. 17. NETWORK ARCHITECTURE  The second generation implementations consist of TDMA/CDMA implementations with 900, 1800 MHz frequencies  Third generation mobile systems are intended to provide a global mobility with wide range of services including voice calls, paging, messaging, Internet and broadband data  3G mobile offers access to broadband multimedia services, which is expected to become all IP based in future 4G systems Conti…
  18. 18. NETWORK ARCHITECTURE  4G architecture includes three basic areas of connectivity; PANs (such as Bluetooth), WANs and cellular connectivity  4G will provide a wide range of mobile devices that support global roaming  4G architecture is designed to optimize network performance, improve cost efficiency and facilitate the uptake of mass market IP-based services
  20. 20. NETWORK ARCHITECTURE  In 5G mobile IP, each cell phone is expected to have a permanent "home" IP address, along with a "care- of" address that represents its actual location  IPv6 is needed for many addresses and the multiple layers of subnetting  128 bits (4 times more than current 32 bit IPv4 address) may be divided into four parts (I thru IV) for supporting different functions. The first 32-bit part (I) may be defined as the home address of a device while the second part (II) may be declared as the care-of address allowing communication between cell phones and personal computers
  21. 21. Comparison of 1G-5G Technologies
  22. 22. NETWORK ARCHITECTURE  The third part (III) of IPv6 address may be used for tunneling to establish a connection between wire line and wireless network. In this case an agent (a directory server) will use the mobile IP address to establish a channel to cell phones  The fourth and last part (IV) of IPv6 address may be used for local address for VPN sharing. Figure 4 illustrates the concept
  23. 23. KEY CONCEPTS OF 5G  Real wireless world with no more limitation with access and zone issues  Internet protocol version 6 (IPv6), where a visiting care-of mobile IP address is assigned according to location and connected network  One unified global standard  Additional features such as Multi-Media Newspapers, also to watch T.V programs with the clarity as to that of an HD T.V Conti…
  24. 24. KEY CONCEPTS OF 5G  We can send Data much faster that that of the previous generations  5G will bring almost perfect real world wireless or called “WWWW: World Wide Wireless Web
  25. 25. FEATURES OF 5G NETWORKS TECHNOLOGY  5G technology offer high resolution for crazy cell phone user and bi-directional large bandwidth shaping  the advanced billing interfaces of 5G technology makes it more attractive and effective  5G technology also providing subscriber supervision tools for fast action  high quality services of 5G technology based on Policy to avoid error  traffic statistics by 5G technology makes it more accurate Conti…
  26. 26. FEATURES OF 5G NETWORKS TECHNOLOGY  5G technology offer transporter class gateway with unparalleled consistency  Through remote management offered by 5G technology a user can get better and fast solution  The 5G technology also support virtual private network  The uploading and downloading speed of 5G technology touching the peak  5G technology will take all delivery service out of business prospect
  27. 27. CONCLUSION  The current and future trends in mobile systems is considered that includes the evolutionary path starting from first generation mobile phone systems and is continuing to the development of 5th generation systems  There are some other projects, which are undertaken by 5G technologies. Here we want to mention that 4G mobiles are working these days in some countries, and 5G technologies are coming in future Conti…
  28. 28. CONCLUSION  It is very interesting that all the nearby countries are locally connected in 5G Network that is if you like to call in Pakistan or China from India, this call should be local rates, it is not consider as ISD calls
