Digital Gangetic Plains:

IIT Kanpur Digital Gangetic Plains Pravin Bhagwat Dheeraj Sanghi Pricipal Investigators Digital Gangetic Plains Project IIT Kanpur S.G. Dhande Director, IIT Kanpur Head, Kanpur Lucknow Lab Media Lab Asia Manoj Kumar Project Manager Digital Gangetic Plains Project IIT Kanpur

Worldwide Mobile Phone Penetration:

IIT Kanpur Worldwide Mobile Phone Penetration *Source EMC database 39% 65% 22% 3.9% 21%

The key challenge:

IIT Kanpur The key challenge 1G 2G 3G Mobile Telephony evolution has been shaped by technical innovations and market forces in the west This business model can thrive when average per capita income is high ($20K) Wireless systems being deployed in India are successful in Metro pockets, but providing cost effective voice and data services to the masses will remain a challenge for many years to come. Achieving necessary cost reduction for mass market penetration Reaching out to the remaining 83% of the world market Generating conducive climate so that seeds of innovation and entrepreneurship can take root 4G

Barriers to Digital Empowerment:

IIT Kanpur Barriers to Digital Empowerment Equipment Operations Value Pricing of Communication Service Spectrum $$ Rs. 2-3 per minute 1/3 1/3 1/3 Cost amortized over seven years People in developed economies are willing to pay this price because voice is a very high value application Willingness to pay for data is much less We cannot peg our hopes for price reduction on continued market growth since price elasticity in this market has already been maximized

Bridging the digital divide:

IIT Kanpur Bridging the digital divide Customize mass market technology for our use Lower regulatory barriers Enable entry of grass roots entrepreneurs Equipment Spectrum O&M

Strategy #1:

IIT Kanpur Strategy #1 Cost of inventing a new technology is high Leverage worldwide economies of scale and customize existing technology for our own needs. Equipment Operations Spectrum

Promising technology: 802.11b:

IIT Kanpur Promising technology: 802.11b Replacement for Ethernet Supported data rates Current: 11, 5.5, 2, 1 Mbps Future: 20+ Mbps in 2.4 GHz and up to 54 Mbps in 5.7 GHz band Range Indoor 20 - 25 meters Outdoor: 50 – 100 meters Transmit power up to 100 mW Cost: Chipsets $ 25 – 40 AP $120 - $1000 PCMCIA cards $60 - $110

Technology Customization Example: Internet Access in Rural India:

IIT Kanpur Technology Customization Example: Internet Access in Rural India 5 - 8 Km Metro Internet Village 802.11b range extension using directional, home grown, custom made antennas Internet access within 0.5 Km radius of the village center Further range extension using multi-hopping Alternate path routing for high reliability

DGP Research Program:

IIT Kanpur 384 Kbps 56 Kbps 54 Mbps 72 Mbps 5-11 Mbps 1-2 Mbps 802.11 DGP Research Program 802.11b 802.11{a,b} Turbo .11a Indoor 10 – 30m IS-95, GSM, CDMA WCDMA, CDMA2000, HDR Outdoor 50 – 200m Mid range outdoor 200m – 4Km Long range outdoor 5Km – 20Km Long distance com. 20m – 50Km µ wave p-to-p links .11b p-to-p link Range Extension Multi Hopping Performance & range studies

Three Value Propositions:

IIT Kanpur 384 Kbps 56 Kbps 54 Mbps 72 Mbps 5-11 Mbps 1-2 Mbps 802.11 Three Value Propositions 802.11b 802.11{a,b} Turbo .11a Indoor 10 – 30m IS-95, GSM, CDMA WCDMA, CDMA2000, HDR Outdoor 50 – 200m Mid range outdoor 200m – 4Km Long range outdoor 5Km – 20Km Long distance com. 20m – 50Km µ wave p-to-p links .11b p-to-p link Lost cost mobile voice+data services for the rural sector Cost effective alternative to long distance leased lines. Inexpensive solution for the last mile problem

Strategy #2:

IIT Kanpur Strategy #2 Let thousand flowers bloom Equipment Operations Spectrum

Regulatory Issues:

IIT Kanpur Regulatory Issues 5.15 – 5.35 Ghz 5.725 – 5.825 Ghz 2.4 – 2.483 Ghz Indoor use permitted License required for outdoor use (4 W EIPR max) No indoor or outdoor use permitted as yet 802.11b 1, 2, 5.5, 11Mbps 802.11a Up to 54 Mbps

Strategy #3:

IIT Kanpur Strategy #3 Experiment with new business models. Do not emulate the west. Equipment Operations Spectrum

Example 1: Unwired PCO:

IIT Kanpur Example 1: Unwired PCO PCO PCO PCO PCO PCO Benefits Low cost method of expanding telephony services PCO’s can offer in-bound call service Portability Additional revenue stream via offering Internet access Unlimited potential for offering value-added services Wireless access around each PCO

DGP Project Milestones:

IIT Kanpur DGP Project Milestones River Ganges IIT Kanpur 5.1 Km Mandhana June ‘02 22.5 Km Safipur Sept ‘02 Lodhar 2.3 Km April ‘02 Saroha Dec ‘02 17.3 Km 12 Km Bithoor Nov ‘02 Lucknow End to end distance 85 Km March ‘02 Rajajipuram 38 Km 37 Km Digital Gangetic Plains project is a proof of concept that wireless connectivity in rural areas is technically and economically viable. Built using off the shelf wireless equipment (originally designed for indoor use), DGP is perhaps the world’s largest rural outdoor 802.11 network today.

Current IT needs of Rural Market:

IIT Kanpur Current IT needs of Rural Market Tahseel Police Village interconnecting geographically disperse govt. offices is the first step towards IT enabling villages Several govt. agencies (state of Uttaranchal, Chattishgarh) have approached us to design a wireless connecitivity solution for them Building a separate network for each Govt. agency is costly and inefficient Health Care/ Education Agriculture

A possible roll out Scenario:

IIT Kanpur A possible roll out Scenario Tahseel Village Police Agriculture Health Care/ Education A cost effective solution is to have a common infrastructure maintained by a central agency Other agencies can make use of it for their connectivity requirements

Concluding Remarks:

IIT Kanpur Concluding Remarks Recommendations Open up license free spectrum for low cost wireless connectivity applications Work with other partners to harmonize use of spectrum across Asia/Pacific region Facilitate interaction between technologists, govt. agencies, and entrepreneurs by launching a focused national initiative on low cost rural connectivity 802.11{b,a} Will continue to grow in US/European market Public spaces, home, industry vertical, and enterprise market Offers a great promise for bringing low cost networking services to the Indian mass market
