1. Background Bhutan Telecom is the incumbent telecom operator in Bhutan (100% government owned)
Provides 3 line of services: fixed, mobile and Internet
Fixed line subscribers: 25,000 plus
Mobile subscribers: 250,000 plus
Data subscribers:
Mobile Data users: 3G - 2,000, GPRS/EDGE- 48,000
DSL Broadband users – 8,000, leased line – 160
Potential customer base: 650,000

Current State…Network Infrastructure
2. Transmission Network (Domestic) Fiber Optic Network
Very limited in place currently
Existing network is 100% on OPGW except for the last mile/approach to terminating stations
Installed capacity: STM1 – STM4
Microwave Radio Network Microwave SDH Radio on the East-West backbone
Microwave PDH Radio mostly on the access/spur routes
Installed capacity: 2E1 to (2+1) STM1

Current State…Network Infrastructure
2. International connectivity
Fiber Optic – STM1 to LINX, London - STM1to HKIX, Hongkong
Satellite - 10 Mbps with British Telecom, UK

Mobile Service to rural Bhutan
3. GSM mobile service to rural communities
Funding scheme : 50% Universal Service Fund (USF) and 50% Bhutan Telecom fund (USD 6 million)
Total GSM BTS deployed as part of this USF project : 23
Total PDH microwave hops deployed as backhaul for BTS: 25+

Innovating to suit rural conditions
Transportation of materials to rural sites

Innovating to suit rural conditions
Locally designed and fabricated BTS shelters

Rural Customer Base
Typical Rural Community required to be provided mobile service
![Page 14: Taking mobile services to the much needed rural communities of Bhutan](https://reader035.fdocuments.net/reader035/viewer/2022062800/56814168550346895dad4b25/html5/thumbnails/14.jpg)
Challenges
Difficulties faced:
Bhutan has mountainous terrain…very difficult to build backhaul radio links
Rural communities do not have electricity supply…therefore BTS stations and PDH microwave backhaul stations need to be solar powered (Capital intensive)
Rural communities do not have access motor roads… transportation of materials become very difficult. Subsequent maintenance of the network also becomes difficult
Return on capital deployed is minimal
