NEXT 25 YEARS 4G IN INDIA?

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

What is 4G?

The 3G

Large Coverage Outdoor - High MobilityUp to 14Mbps

THE NEEDS Adaptive high performance transmission system Great candidate for SDR

Large Coverage – 100Mbps

Macro Cells Pico Cells

Isolated HotSpots – 1Gbps CoverageIndoor – Very Low Mobility

The 4G

ITU designed 4G in 2002 with the official name “3G Long-Term Evolutions” or 3.9GWill allow users to download a full-length feature film within five minutesWill also be able to stream high-definition television and radio to hand-held devicesThe basic difference between 3G and 4G is in data transfer and signal quality

What is 4G?

The highest download and upload speed in 3G are 14 Mbps and 5.8 Mbps respectivelyIn 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 callsWith packet switching, resources are only used when there is information to be sent across4G uses spiral multiplexing

What is 4G?

NEED OF 4G

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

• 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

4G Wireless: One View

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)

Evolution of 4G

Evolution of Processors and DSP Technology for 4G

Except for the Scandinavian countries, a few countries have started the 4G commercially

In the US, Sprint Nextel initiated the service

Countries using 4g are Japan, Korea, Germany, Spain, China, and England.

Which countries have 4G?

A look at fundamental requirements

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

Infrastructure for 4G

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

4G Evolution into Convergence

Wireline Bandwidth Demand Projection for Next 25 Years

~ 50 % improvement in performance

1. Mobile locks to the STRONGEST base

2. Mobile sends measurements of path losses for nearby bases to serving base

3. Serving base forwards measurementsto nearby bases

4. Bases assign channels to all packets/mobiles

5. Bases forward channel assignment info to nearby bases

Has already begun the process of introducing 4GIndia is among the latecomers in 3GIt is felt that by the time the implement 3G fully, 4G technologies such as LTE will be available commerciallyIt has taken three years for the government to decide on 3G-spectrum auction policy4G could face the same delay unless India wants to catch up with the rest of the world

4G in India?

THAT’S ALL ABOUT 4G
