Internet and India: Vision & Opportunities Demystifying Broadband Internet in India’s Context Ashok Jhunjhunwala, IITM, Chennai ashok@tenet.res.in
2
TeNeT Group, IITMTelecom India, Nov03 2 Internet is Power Internet is not just a means of communications, but is Power can enable people in all kinds of ways But Internet in India has grown slowly is expensive Internet based Education, Internet based Commerce and Internet based Entertainment is virtually non-existent What does India require?
3
TeNeT Group, IITMTelecom India, Nov03 3 Dial-up Internet Internet widely available on fixed telephone lines (45 million) using dial-up provides 10 kbps average bit-rate on 33.6 kbps connection at Rs 35 per hour Rural / Small town telephones often connect at 9.6 kbps enables email and some browsing Mobile (20 million) can support 100 kbps shared connection (for all users in a sector) on GPRS/3G-1X less than even dial-up rate at Rs 26 per hour great for handsets -- but meaningless for homes/ small offices
4
TeNeT Group, IITMTelecom India, Nov03 4 What will we like at homes/ small offices? Low bit-rate connection for messaging at Rs 100 per month 33.6 kbps (dedicated) Always On connection at Rs 250 per month will enable email, browsing and some education/commerce 100 kbps (dedicated) Always On connection at Rs 500 per month will enable video-conferencing, some entertainment 2Mbps (dedicated) Always On connection at Rs 1000 per month will enable video on demand, entrtainment Can we get there??
5
TeNeT Group, IITMTelecom India, Nov03 5 Where are the bottlenecks? International Network Rs 100,000 per month per Mbps (one way to/from USA) if one uses a 100 kbps connection to continuously pull traffic from a US based server, the international network alone will cost Rs 10K per month? Backbone Network cost in India Rs 20,000 per month per Mbps (one way, farthest distance) Access Network: connecting from PoP to home/office dial up costs Rs 26 per minute for telephony alone
6
TeNeT Group, IITMTelecom India, Nov03 6 International Link charges limits Internet speed in India At Rs 100K per month for a 1 Mbps Internet link and with most traffic going to servers located in the West Internet bandwidth can not be made affordable Problem complicated by the fact that Indian ISPs often connect to each other only via international links Answer: Internet Exchange in India all traffic with source and destination in India must remain in India Create Indian Content and host it in India Mirror / host International sites in India reduce International traffic fraction from 85% to 25% in three years
7
TeNeT Group, IITMTelecom India, Nov03 7 Backbone Network cost in India still high At a cost of Rs 20,000 per Mbps (one way) between Metros, Backbone Network cost is still a bottleneck reduce it by a factor of three to four in next couple of years With huge fibre build-up taking place, this is likely incentives needed to speed this up
8
TeNeT Group, IITMTelecom India, Nov03 8 For home/office connectivity Access is the primary bottleneck Access Choices: Dial-up Internet: too costly and too little Mobile: too costly and far too little DSL on Copper: available only with incumbent (BSNL/MTNL) Coaxial Cable: Can we overcome Quality? Wireless: Can we provide enough bandwidth? Fibre to the home/curb: build may take time ( with Last METERS of Copper or wireless)
9
TeNeT Group, IITMTelecom India, Nov03 9 Digital Subscriber Loop on Copper What is technologically possible today? ADSL: 6 Mbps downlink and 512 kbps uplink for 4 Kms cu VDSL: 20 Mbps downlink and 1 Mbps uplink for 700 m But who has copper links to homes/offices? Only BSNL/MTNL What are the lengths of such copper loop mostly 3-4 Kms; 5% may be 700 m (connected using DLCs) What is the quality of such copper? Poor, except when 700 m copper links with DLCs are used can not be used to provide even lite-ADSL Dishnet/Bharati are putting their own cables in a limited way
10
TeNeT Group, IITMTelecom India, Nov03 10 HDSU IAN Internet PSTN 128 kbps 2 Mbps V5.2 IP BSNL provide DSL service in 50 cities using DIAS 128/64 kbps Internet + simultaneous voice 2 Mbps Internet + phones Always ON Internet connection at Rs 850 per month is likely to come down to Rs 500 per month
11
TeNeT Group, IITMTelecom India, Nov03 11 Internet on Coaxial Cable Widely used in USA 10 to 40 Mbps broadcast in forward direction and 512 kbps to 1 Mbps shared up-link Coaxial provides TV to 60 million Indian homes at carrier charge of Rs 80 per month (in contrast to charge of $ 20+ per month in most developing countries) how is this possible? Choice of cable, connectors, amplifiers and deployment and maintenance methodology are all designed to provide TV services at Rs 80 per month Most attempts in India towards conversion of the coaxial plant for two-way Internet communication has been a failure
12
TeNeT Group, IITMTelecom India, Nov03 12 Wireless: The happening Area can it solve our access problem to homes/ small offices? Wireless Technologies: 2.5 G Mobile: 3G-1x/GSM/GPRS can deliver 100 kbps shared connection to all subs in a sector may deliver 1 Mbps shared connection in future (3G) still at best comparable to 56 kbps dial-up; uses huge spectrum; will be costly --- can compete with dial-up corDECT WiLL: 35/ 70 kbps dedicated Always On connection comparable to dial-up: require aggressive strategy to provide Low bit-rate connection for messaging at Rs 100 per month 33.6 kbps (dedicated) Always On connection at Rs 250 per month 2.5G corDECT will provide Always On 100 kbps dedicated connectivity
13
TeNeT Group, IITMTelecom India, Nov03 13 Wireless Technologies (continued) 802.11 Wireless LAN ideal LAN for office, homes, public places (100 meters) but required fibre/DSL connection to base station PMP Systems (proprietary) providing 64kbps to 2Mbps connection companies like SIFY provides 64 kbps at Rs 20K per month shared connection to multiple user in a building 802.16 WiMax (OFDM) new standard -- 10 Mbps shared connection in a sector may amount to 500 kbps dedicated connection to each user what price point and when? 4G wireless / MIMO promises more: when, how much and at what cost?
14
TeNeT Group, IITMTelecom India, Nov03 14 Fibre Access Network finally beating the bandwidth game Fibre to the Building / Curb last Meters on copper (Ethernet) or wireless (802.11) 100 Mbps to each user possible is being used today by almost all operators BSNL, MTNL, Reliance, Bharati, Tata-Tele, Shyam, HFCL STM-1 Ring Gig E ring Subscriber Services RT COT Broadband Switch Narrowband Support.. ISDN Leased line n X 64 VDSL HDSL ADSL POTS Ethernet PSTN DATA
15
TeNeT Group, IITMTelecom India, Nov03 15 But is Fibre Access affordable? How deep can the Fiber go? Key drivers Cost of Fiber Termination Line Terminating Electronics Power Backups Depends on Customer Density and Affordability For dense urban areas of India, Fibre to the building is the most cost effective solution comparable to wireless provided one can get it 1 in 3 homes but can one install fast enough? FTTB FTTH
16
TeNeT Group, IITMTelecom India, Nov03 16 Terminals PCs are too expensive for India’s homes VIA PC and AMD has brought cost below Rs 15K still too high beyond 7 to 10 million homes Need new solutions: Rs 10K devices to reach next 20 million homes Rs 5K devices to reach next 50 million homes Messaging terminals at Rs 1.5K for 50 million homes may be handheld
17
TeNeT Group, IITMTelecom India, Nov03 17 Can we get there? Low bit-rate connection for messaging at Rs 100 per month Mobile or corDECT immediate 33.6 kbps (dedicated) Always On connection at Rs 250 per month corDECT or 3G mobile immediate 100 kbps (dedicated) Always On connection at Rs 500 per month DIAS (incumbent) or 2.5G corDECTimmediate or DSL on new copper slow deployment 2Mbps (dedicated) Always On connection at Rs 1000 per month Fibre Access Network with Ethernet/ 802.11 or DSL on new copper slow deployment or 802.16 (only about 500 kbps)early 05
18
TeNeT Group, IITMTelecom India, Nov03 18 To Sum Up To enable India with Internet, we need Indian traffic to stay in India: NIXI Indian content and hosting/mirroring International sites Education, Commerce and entertainment content needs push Reduce International traffic percentage from 85% to 25% Reduction of Backbone network cost in India by a fourth Always On Access providing differential services at costs of Rs 100 to 1000 per month 2 Mbps Broadband connection possible only by Fibre Access growth will be slow till we find new technology solution Terminals widely affordable in India
