Higher bandwidth enables a range of new applications. For the consumer Video streaming, TV broadcast Video calls, video clips – news, music, sports Enhanced gaming, chat, location services… For business High speed teleporting / VPN access Sales force automation Video conferencing Real-time financial information

PowerPoint Presentation:

IS-95 IS-136 & PDC GSM- EDGE GPRS HSCSD IS-95B Cdma2000-1xRTT Cdma2000-1xEV,DV,DO Cdma2000-3xRTT W-CDMA EDGE TD-SCDMA 3G 3GPP 3GPP2 2G 2.5G

PowerPoint Presentation:

Universal global roaming Multimedia (voice, data & video) Increased data rates 384 kbps while moving 2 Mbps when stationary at specific locations Increased capacity (more spectrally efficient) IP architecture Problems No killer application for wireless data as yet Vendor-driven

PowerPoint Presentation:

First steps to 3G 270 commercial GPRS networks 141 networks deploying GPRS/EDGE 84 commercial EDGE networks 121 commercial Cdma2000 1x networks 3G WCDMA: 134 licenses awarded 71 commercial WCDMA networks 22 commercial CDMA 1x EV-DO networks Evolved 3G HSDPA: all WCDMA operators expected to upgrade to HSDPA (SW upgrade to BTS) CDMA 1x EV-DV: limited industry support

PowerPoint Presentation:

Wireless LANs Faster than 3G 11 or 56 Mbps vs. <2 Mbps for 3G when stationary Data experience matches the Internet With the added convenience of mobile Same user interface (doesn’t rely on small screens) Same programs, files, applications, Websites. Low cost, low barriers to entry Organizations can build own networks Like the Internet, will grow virally Opportunity for entrepreneurs Opportunity for wireless operators

PowerPoint Presentation:

3.5G or HSDPA (High Speed Downlink Packet Access) is an enhanced version and the next intermediate generation of 3G UMTS. It comprises the technologies that improve the Air Interface and increase the spectral efficiency, to support data rates of the order of 30 Mbps. 3.5G introduces many new features that will enhance the UMTS technology in future. 1xEV-DV already supports most of the features that will be provided in 3.5G. These include: Adaptive Modulation and Coding Fast Scheduling Backward compatibility with 3G Enhanced Air interface 9

PowerPoint Presentation:

Also known as ‘Mobile Broadband everywhere’ ‘MAGIC’ Mobile Multimedia Communication Anywhere, Anytime with Anyone Global Mobility Support Integrated Wireless Solution Customized Personal Service According to 4G Mobile Forum, by 2008 over $400 billion would be invested in 4G mobile projects. In India, communication Minister Mr. Dayanidhi Maran, has announced a national centre of excellence to work in 4G arena. 10

PowerPoint Presentation:

Transmission at 20 Mbps 2000 times faster than mobile data rates 10 times faster than top transmission rates planned in final build out of 3G broadband mobile 10-20 times faster than standard ADSL services. Companies developing 4G technology Cellular phone companies: Alcatel, Nortel, Motorola, IT Companies: Hughes,HP,LG Electronics 11
