1 Telecommunication Needs for the Internet Infrastructure in Bangladesh Presentation at the Workshop on Nationwide Internet Access & Online Applications Dhaka, Bangladesh 23 May 2004 Professor Saifur Rahman, Director Manisa Pipattanasomporn, Graduate Student Alexandria Research Institute Virginia Tech IT Facts in Bangladesh 50 telephone lines and 3 Internet users per 10,000 population High installation charge of roughly $200 for a new telephone line Long waiting time for a new connection of 2-4 years
2 Themes for Discussion Review existing IT infrastructures in Bangladesh Review various access technologies Identify least-cost ICT solutions for Internet access in Bangladesh Broad Benefits from ICT ICT for Education ICT for Health ICT for Economic Opportunity ICT for Empowerment and Participation
3 ICT for Education Wireless web reaches village children Using computers to assist in teaching mathematics Source: BBC News Primary school children are introduced to computers using multimedia CDs. Source: BBC News Schools in remote villages can serve as a venue for adult education, health care and small business activities ICT for Health The telecentre in Sonagazi Source: BBC News New horizons for Bangladeshi doctors Online medical centers to provide better care for the sick CD-ROMs to show how to better treat patients Transmission of tests to the hub in the capital city for analysis
4 ICT for Economic Opportunity ICT can contribute to better marketing opportunities through access to information on: Weather Farming best practice Crop status Global market price ICT for Empowerment and Participation ICT contributes to fostering empowerment, and making government processes more efficient. State of Madhya Pradesh, India Faster and more transparent access to government services. Farmers can get copies of land titles for 10 cents (previously $100 from corrupt officials).
5 Existing IT Infrastructure in Bangladesh Satellite Microwave Links Optical Fiber Links Cellular Coverage Satellite & Microwave Links Satellite is the only way to communicate internationally Microwave links are the major communication backbone of the country Microwave speed range from Mbps Source: BTTB Annual Report 2001
6 Grameen Coverage as of March 2004 Railway lines Fiber Links & Cellular Coverage Backbone is transferred from microwave links to optical fiber links Roughly 1,800-km fiber is installed along 2,900-km railway track Leased by Grameen telephone to spread telecom footprint across the country Source: Internet Access Alternatives < 35km > 35km Last-Mile Technologies Wireline: POTS, DSL, Cable Modem Wireless: Fixed Wireless (WLL, LMDS, MMDS, VSAT) Wireless Local Area Network (WLAN) Wireless Metropolitan Area Network (WMAN) Wireless Wide Area Network (WWAN)
7 POTS/DSL POTS = Plain Old Telephone Service (56 Kbps) DSL = Digital Subscriber Line (768 Kbps) Telephone Internet Router ISP Modem PSTN Modem Computer POTS: simplest way to connect to Internet, just modem and PC DSL: a high-speed connection via a telephone lines Cable Modem Delivering high-speed Internet services over cable TV systems (0.5-1Mbps) A splitter splits the signal to TV outlets and the cable modem Cable modem connects directly to the PC
8 CorDECT WLL Repeater End user End user CorDECT WLL = Wireless Local Loop based on DECT standard CorDECT WLL has been used extensively in India for rural telecommunication WLL provides: Base Station Simultaneous telephone and Internet connection (35-70kbps) Source: MMDS/LMDS MMDS: support max 3.2Mbps per base station, maximum coverage of 20-km NLOS LMDS: support max 155Mbps, maximum coverage of 3 km with LOS connection
9 Wireless Local Area Network (WLAN ) Operates in unlicensed bands Provides speed of up to 54Mbps with a and up to 11Mbps with b Coverage meters Access Point Wireless Card Up to 50 km WMAN provides path between subscriber sites and a core network It can provide 60 customers with T-1 speed, range of 50km can add mobility to users in the building Recently introduced, late 2003
10 Mobile Broadband (WMAN ) seeks to boost real-time data transmission rate to 1 Mbps or more. Cell ranges of up to 15 kms or more. Deliver speed to mobile users traveling at speeds up to 250 km/h. Availability: 2005 or later WWAN WWAN uses cellular networks to enable Internet connection from cellular phones. GSM CDMA GPRS EDGE CDMA2000 WCDMA 2G 2G 2.5G 2.5G 3G 3G 9.6 Kbps 14.4 Kbps 171 Kbps 384 Kbps 2 Mbps 2-10 Mbps Require infrastructure changes, e.g. new base station addon and software upgrade and new handsets

15 ICT Solution for Bangladesh Take a closer look at a target country: Bangladesh Area: 144,000 km 2 - Flat terrain Population: 133 million people (925 persons/km 2 ) Infrastructure: optical fiber, cellular tower, microwave station With existing infrastructures, WLL or are least-cost options. In any case, backbone must be able to support data needed at base stations Possibility for Nationwide Telecom- and-internet Access in Bangladesh 35 km coverage In Bangladesh, about 90% of the population could be served by as few as 25 towers with multiple base stations using WLL or technologies.
16 Conclusions Least-Cost ICT Solution for Bangladesh Recommend WLL or for Bangladesh. Per unit cost will depend on number of clients that can be served from one location To this end, the proposed solutions will vary depending on the available ICT infrastructure, applications, speed requirements, and ability to pay for the services.
