2. Presentation Goals INTRODUCTION WHAT IS 4G? NEED OF 4G EVOLUTION OF 4G EVOLUTION OF PROCESSORS AND DSP TECHNOLOGY FOR 4G WHICH COUNTRIES HAVE 4G? INFRASTRUCTURE FOR 4G 4G EVOLUTION INTO CONVERGENCE WiMax WIRELINE BANDWIDTH DEMAND PROJECTION FOR NEXT 25 YEARS 4G IN INDIA?
3. Introduction 4G, the successor of 3G, will soon become the standard for cellular wireless The technology is currently available in some countries but it is still being perfected The aim is to achieve “ultra broadband speed” – to be counted in gigabytes per second
4. What is 4G? CDMA GSM/UMTS IEEE Cellular IEEE LAN CDMA (IS-95A) GSM TDMA IS-136 IEEE 802.16 IEEE 802.11 2G CDMA (IS-95B) GPRS 802.11g 2.5G cdma 2000 E-GPRS EDGE WCDMA FDD/TDD TD-SCDMA LCR-TDD 802.11a 3G 1xEV-DO Rev 0/A/B HSDPA FDD/TDD HSUPA FDD/TDD Fixed WiMAX 802.16d WiBRO 802.11g 3.5G UMB 802.20 HSPA+ Mobile WiMAX 802.16e 802.11n LTE E-UTRA 3.9G
5. The 3G Large Coverage Outdoor - High Mobility Up to 14Mbps
6. The 4G Macro Cells Pico Cells Large Coverage – 100Mbps Isolated HotSpots – 1Gbps Coverage Indoor – Very Low Mobility THE NEEDS Adaptive high performance transmission system Great candidate for SDR
7. What is 4G? ITU designed 4G in 2002 with the official name “3G Long-Term Evolutions” or 3.9G Will allow users to download a full-length feature film within five minutes Will also be able to stream high-definition television and radio to hand-held devices The basic difference between 3G and 4G is in data transfer and signal quality
8. What is 4G? The highest download and upload speed in 3G are 14 Mbps and 5.8 Mbps respectively In 4G the download speed is up to 100 Mbps for moving users and 1 Gbps for stationary users 4G is adoption of packet switching instead of circuit switching in voice and video calls With packet switching, resources are only used when there is information to be sent across 4G uses spiral multiplexing
9. Mobile marketing and advertising Business potential viewed with great enthusiasm within dominant and leading markets. Mobile Search Knee for takeoff : replicate desktop success M-commerce/M-Wallet SMS messaging enables interactivity with other forms of entertainment (e.g., Polling)., Credit purchases. Mobile Gaming Evolving into “Casual Gaming” with challenges for distribution and revenue collection. Mobile e-Mail Going mass scale as productivity enhancer to move into rank and file employees beyond executives and field sales force. Presence, MMS, Instant Conferencing, push-to-video, and mobile news MusicStation (UK) from Vodafone: Omniphone’s deal with Telenor (Sweden), 3 (HK), and Vodacom (SA). Content Focus shifting from “Major Media Brand - Formal Content” to “User Generated Content” in mobile networks. Photo swapping, mobile social media, one-to-one communications Revenue sharing Music and video sharing, with subscribers via ads and P2P E.g., SeeMeTV by 3 allows video uploaders to get paid when their content is downloaded. Webco Platform Deals with (Vodafone/MySpace, Sprint/GOOG), Android NEED OF 4G
10. 4G Wireless: One View 4G WOFDM high speed downlink “a wireless cable modem” Complement to EDGE/UMTS High peak data rates (up to 10 Mb/s) in a 5 MHz channel spectrum - 500 MHz to 3 GHz 3G EDGE/WCDMA network for uplink, downlink, control and signalling
11. Evolution of 4G The first commercial deployment was by Telia Sonera and NetCom Telia Sonera branded the network “4G” The modem devices on offer were manufactured by Samsung (dongle GT-B3710) The network infrastructure were created by Huawei (in Oslo) and Ericsson (in Stockholm)
12. Evolution of Processors and DSP Technology for 4G
13. Which countries have 4G? Except for the Scandinavian countries, a few countries have started the 4G commercially In the US, Sprint Nextel initiated the service Countries using 4gare Japan, Korea, Germany,Spain, China, and England.
14. A look at fundamental requirements
15. Infrastructure for 4G There are three primary technologies that support 4G – WiMax, LTE, and UMB The main doubt is whether to implement WiMax or Long Term Evolution(LTE) The advantages of LTE are: (i) Faster speed with 100 Mbps for download and 50 Mbps for upload (ii) It makes CDMA and GSM database moot (iii) It offers both FDD and TDD duplexing
16. WiMax WiMAX(Worldwide Interoperability for Microwave. Access) WiMax technology might not achieve the required rate in a high-density area However, WiMax technology becomes useful when it is bundled with IPTV The wireless bandwidth will be roughly 3Mbps/1.5Mbps; but this is nowhere near the +100Mbps/50Mbps that LTE promises

18. 4G Evolution into Convergence
19. Wireline Bandwidth Demand Projection for Next 25 Years
20. 2. Mobile sends measurements of path losses for nearby bases to serving base 4. Bases assign channels to all packets/mobiles 5. Bases forward channel assignment info to nearby bases 1. Mobile locks to the STRONGEST base 3. Serving base forwards measurements to nearby bases ~ 50 % improvement in performance
21. 4G in India? Has already begun the process of introducing 4G India is among the latecomers in 3G It is felt that by the time the implement 3G fully, 4G technologies such as LTE will be available commercially It has taken three years for the government to decide on 3G-spectrum auction policy 4G could face the same delay unless India wants to catch up with the rest of the world
22. THAT’S ALL ABOUT 4G Thank you for your Time!
