Slide 1: 3G/4G Wireless Technology's Presented By Deva.A Jerin. J.L Theni Kammavar Sangam College of Technology Slide 2: Wireless is the transfer of information over a distance without the use of electrical conductors or wires. The distances involved may be short (a few meters as in television remote control) or long (thousands or millions of kilometers for radio communications). Wireless Slide 3: Delivers real time information. Helps in quick and accurate decision making. Continuous supply of information whenever needed. Increases productivity. Reduces costs via more accurate and timely data capture. Incorporate professionalism in the working in the organization. Why Wireless? Slide 4: Need for 3G Drawbacks of previous generation 1G compares unfavorably to its successors. 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. 2G technologies weaker digital signals may not be sufficient to reach a Cell tower. 2G Difficult roaming between countries using different systems. Back ground Noise, lossy compression during CODECS. Slide 5: 3G wireless technology represents the convergence of various 2G wireless telecommunications systems into a single global system that includes both terrestrial and satellite components. 3G High-speed, mobile supports video and other rich media, always-on transmission for e-mail, Web browsing, instant messaging. It is based on the International Telecommunication Union (ITU2000) family of standards Services include wide-area wireless voice telephony, video calls, and broadband wireless data, all in a mobile environment. What's New in 3G? Slide 6: 3G Features Global Roaming. Send and Receive E-Mail Messages. High Speed Web. Superior Voice Quality. Tele/Video Conferencing. Electronic agenda meeting reminder. 3d Animation Games. Website creating Using Mobile Phones. Etc…. Slide 7: Our Real Time Implementation in 3g Technology ……………. Slide 8: "Open Smart Classroom" by using 3G Technology Both Remote and Local area Students can easily get interact with queries, and listen at the same time. Access in Inside campus - Remote areas - WI-FI Wi-Max Slide 9: WI-FI Block 2 Block 3 Block 1 Inside Campus Slide 10: Wi-MAX Area 2 Area 3 Area 1 both Remote areas and Local area Slide 11: Remote area Local area Open Smart Class rooms Slide 12: Both Local area and Remote areas Students Can interact the teacher by Queries Suggestions Feedback Language Translation. World wide access. Features of our Implementation Slide 13: 4'th Generation It is a frame work for to meet the need of a universal highspeed wireless networks. It supports Interact multimedia services such as Tele conferrencing. wireless Internet over wide bandwidth with higher data rate. It will for reasonable low cost than previous Generation. Still in the cloud of ITU and IEEE of 3GPP LTE from UMTS and WI -MAX Slide 14: New in 4G Entirely Packet Switched Network All Networks are Digital Higher bandwidth at Low cost (up to 100 mbps) Tight Network Security Potential Application : Virtual Presence Virtual Navigation Tele Medicine Tele geo-Processing Crisis- management application Education purpose Slide 15: 802.11a/g 1995 2000 200 Mbps ~ 14.4 kbps 50 Mbps 144 kbps 20 10+ 384 kbps 2005 2G (Digital) 1G (Analog) 2.4 GHz WLAN 802.11b 4G PAN 5 GHz WLAN 3G (IMT2000) Fast Slow 1Gbps OFDMA CDMA 5 GHz WLAN 802.11n WiBro Slide 16: Future Enhancement By Using 4G Technology, we aimed to prepare that “Open Smart Classroom” in Real time application using Wi-Bro with Specs with virtual Screen . Multi Language Translation. WiBro (Wireless + Broadband) Slide 17: Thank you
