- 3. Introduction to 5G What is 5G? What does it offer?
- 4. What is 5G? • 5G Wireless: 5th generation wireless technology • Complete wireless communication with almost no limitations • Can be called REAL wireless world • Has incredible transmission speed • Concept is only theory not real
- 5. What does it offer? • Worldwide cellular phones • Extraordinary data capabilities • High connectivity • More power & features in hand held phones • Large phone memory, more dialing speed, more clarity in audio & video
- 6. Evolution from 1G to 5G 1G 2G 3G 4G 5G
- 7. 1G • Developed in 1980s & completed in early 1990s • Based on analog system • Speed up to 2.4 kbps • AMPS (Advance Mobile Phone System) was launched by the US & it was the 1G mobile system • Allows user to make voice calls in 1 country
- 8. 2G • Developed in late 1980s & completed in late 1990s • Based on digital system • Speed up to 64 kbps • Services such are digital voice & SMS with more clarity • Semi global facility • 2G are the handsets we are using today, with 2.5G having more capabilities
- 9. 3G • Developed between late 1990s & early 2000s until present day • Transmission speed from 125 kbps to 2 Mbps • Superior voice quality • Good clarity in video conference • E-mail, PDA, information surfing, on-line shopping/ banking, games, etc. • Global roaming
- 10. 4G • Developed in 2010 • Faster & more reliable • Speed up to 100 Mbps • High performance • Easy roaming • Low cost
- 11. 5G • Next major phase of mobile telecommunication & wireless system • 10 times more capacity than others • Expected speed up to 1 Gbps • More faster & reliable than 4G • Lower cost than previous generations
- 12. Key concepts • Real wireless world with no more limitations with access & zone issues • Wearable devices • IPv6, where a visiting care of mobile IP address is assigned according to location & connected network • One unified global standard • Smart radio • The user can simultaneously be connected with several wireless access technology • Multiple concurrent data transfer path
- 13. Basic Architecture of 5G
- 14. (OTP) (OWA)
- 15. Open Wireless Architecture (OW • OSI layer 1 & OSI layer 2 define the wireless technology • For these two layers the 5G mobile network is likely to be based on Open Wireless Architecture (OWA) • Physical layer + Data link layer = OWA
- 16. Network Layer • All mobile networks will use mobile IP • Each mobile terminal will be FA (Foreign Agent) • A mobile can be attached to several mobiles or wireless networks at the same time • The fixed IPv6 will be implemented in the mobile phones • Separation of network layer into two sub- layers: (i) Lower network layer (for each interface) (ii) Upper network layer (for the mobile terminal)
- 17. Open Transport Protocol (OTP) • Wireless network differs from wired network regarding the transport layer • In all TCP versions the assumption is that lost segments are due to network congestion • In wireless, the loss is due to higher bit error ratio in the radio interface • 5G mobile terminals have transport layer that is possible to be downloaded & installed – Open Transport Protocol (OTP) • Transport layer + Session layer = OTP
- 18. Application (service) Layer • Provides intelligent QoS (Quality of Service) management over variety of networks • Provides possibility for service quality testing & storage of measurement information in information database in the mobile terminal • Select the best wireless connection for given services • QoS parameters, such as, delay, losses, BW, reliability, will be stored in DB of 5G mobile • Presentation layer + Application layer = Application
- 19. Hardware & Software of 5G 5G Hardware: • Uses UWB (Ultra Wide Band) networks with higher BW at low energy levels • BW is of 4000 Mbps, which is 400 times faster than today’s wireless networks • Uses smart antenna • Uses CDMA (Code Division Multiple Access) 5G Software: • 5G will be single unified standard of different wireless networks, including LAN technologies, LAN/WAN, WWWW- World Wide Wireless Web, unified IP & seamless combination of broadband • Software defined radio, encryption, flexibility, Anti-Virus
- 20. Features of 5G • High resolution for crazy cell phone users • Bi-directional large BW • Less traffic • 25 Mbps connectivity speed • Enhanced & available connectivity just about the world • Uploading & Downloading speed of 5G touching the peak (up to 1 Gbps) • Better & fast solution
- 21. Features (Conti…) • High quality service based on policy to avoid error • Support virtual private networks • More attractive & effective • Provides subscriber supervision tools for fast action
- 22. Advantages of 5G • Data BW of 1 Gbps or higher • Globally accessible • Dynamic information access • Available at low cost
- 23. Applications of 5G • Wearable devices with AI (Artificial Intelligence) capabilities • Pervasive (Global) networks • Media independent handover • Radio resource management • VoIP (Voice over IP) enabled devices • With 6th sense technology
- 24. Conclusion • 3G- Operator Centric, 4G- Service Centric whereas 5G- User Centric • We have proposed 5G wireless concept designed as an open platform on different layers • The new coming 5G technology will be available in the market at affordable rates, high peak future & much reliability than preceding technologies
