3. EVDO

4. Wireless Technology • Wireless phones are found in virtually every corner of the planet. • 2.5 billion people around the world using this technology • Improved Productivity of employees. • Wireless telephony has made the world a smaller place. • As with wireless voice, wireless data is quickly becoming a necessary part of our daily lives.

5. EVDO • EVDO is a telecommunication standard for the wireless transmission of data through radio signals. • Broad Band Network. • standardized by 3rd Generation Partnership Project 2 (3GPP2). • Uses two multiplexing techniques • TDMA • CDMA

6. Synonyms • Is an abbreviation of "Evolution, Data Only" . OR • Is an abbreviation of "Evolution, Data Optimized" . • Official name is: "CDMA2000, High Rate Packet Data Air Interface".

7. History • EV-DO Release 0 was first launched in 2002. • EV-DO, consumers experienced 400-600 Kbps of average downlink throughput with bursts up to 2.4 Mbps. • 4 to 10 times faster than data over CDMA2000 1X (also called 1xRTT). • EV-DO was designed to co-exist with CDMA2000 1X. • The coverage area, frequency plans and antenna are the same as CDMA2000 1X.

8. History • EVDO is first mass market mobile broadband technology • EVDO quickly became the most widely deployed wireless broadband standard in the world. • On August 2007, the EVDO Release 0 networks of 77 operators • Served more than 65 million subscribers in 46 countries worldwide.

9. History • The success of EV-DO Release 0 led to the development of EV-DO Revision A (Rev. A) and Revision B (Rev. B). • Rev. A improves “uplink and downlink performance”, “increases capacity” and support for applications such as “VoIP and video telephony”. • EV-DO Rev. B improves “higher rates and multicarrier support”.

10. Working of CDMA • Uses advanced mathematical techniques. • Allow multiple wireless devices to transmit simultaneously on the same frequency. • Every device is assigned a “unique mathematical signature”. • Applies this signature to the original signal and transmits the modified signal. • A receiver applies the inverse of the mathematical operation to recover the original signal.

11. Why EVDO…?

12. Bukhtyar Ali 07-18

13. IP Based Communication • Traditional wireless networks create a physical path between receiving and sending devices. • EVDO used IP as for internet. IN EVDO: • Each packet is sent independently. • Saves bandwidth for use by other devices.

14. EXAMPLES OF Saving Bandwidth • When neither party on a phone call is speaking, the connection consumes no bandwidth because there are no packets to send. • when an internet web site is accessed, no bandwidth is used until the site starts sending the web page.

15. Throughput • EVDO has a theoretical throughput of 2.4 MBPS. • This is as fast as many residential DSL and cable broadband connections. • A significant advantage of EVDO over competing technologies is that it uses the same broadcasting frequencies as existing CDMA networks on low cost.

16. What is Qualcomm? • Wireless Telecommunication research and development company. • Produced impressive demonstrations of EVDO's capabilities. EXAMPLE Of Demonstrations: • A video conference was conducted with a participant traveling in a car at 60 miles per hour (96 km/hour). • In another demonstration, a phone call was placed from a bullet train moving in excess of 150 miles per hour (240 km/hour).

17. Quallcomm’s EVDO Revolutions • 2 major Revolutions in EVDO are name as “EVDO Rev A” and “EVDO Rev B”. EVDO Rev A: • Enhanced QoS capabilities • VoIP capacity of up to 49 calls per sector • Video Telephony • High-Speed Web Browsing • Video/Music Streaming/Downloads • Multicasting

18. EVDO Rev B • Improves the performance • Provides consistent high data rate • Enables higher streaming rates for video and audio • Provides faster upload of pictures, videos and audio files • Provides faster mobile broadband for laptops

19. Features of EVDO Services Following are some features of EVDO Services: • Modem is Wireless, portable and small sized. • Speed Up to 2Mbps • Useful for Outdoor, Indoor and office use • Mobility in complete SDCA (Short Distance Code Area)

20. Features of EVDO Services • Peak rates of 3.1 Mbps on the downlink and 1.8 Mbps on the uplink. • Sector capacity of 1.5 Mbps downlink and 1.2 Mbps uplink. • Improving the connection setup time • lowering end-to-end delays

22. Comparison Of WIMAX And EVDO WIMAX: • Wireless technology • Required Outdoor device for connectivity • Don’t provide mobility feature EVDO: • Wireless technology • Don’t Required Outdoor device for connectivity • Provide mobility feature

23. Hardware Implementation Following Types of cards are available to utilize EVDO services: • USB • PCMCIA

24. USB • USB devices can be used either on Desktop computers or on Laptops. • They Provide the “Plug & Play” facility.

25. PCMCIA • A PCMCIA card is a credit card-size memory or I/O device that connects to a personal computer, usually laptop computer.  • Hi-Speed USB 2.0 PCMCIA Card supports transmission rates of up to 480 Mbps. • Can be used in Laptop where PCMCIA port is available. • Supports Voice call, SMS & PC-FAX applications.

26. Interface on the Subscriber Machine

27. Architecture of EVDO system • BTS: • For transmission and receiving of signals. Several BTS are connected to one BSC. • BSC: • Performs the task of Radio Resource management. Several BSC are connected to one MSC. • MSC: • Does Switching between different networks.

28. PCF: Packet control function Routes IP data packets between Mobile Station and PDSN. PDSN: Packet Data Service Node Architecture of EVDO system
