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.

BZUPAGES.COM 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

BZUPAGES.COM 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".

BZUPAGES.COM History EV-DO Release 0 was first launched in EV-DO, consumers experienced 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.

BZUPAGES.COM 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.

BZUPAGES.COM 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”.

BZUPAGES.COM 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.

BZUPAGES.COM Why EVDO…?

BZUPAGES.COM 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.

BZUPAGES.COM 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.

BZUPAGES.COM 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.

BZUPAGES.COM 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).

BZUPAGES.COM 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

BZUPAGES.COM 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

BZUPAGES.COM 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)

BZUPAGES.COM 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

BZUPAGES.COM 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

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

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

BZUPAGES.COM 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.
