Broadband Internet is increasingly taking center stage as a critical factor
to the economic development of Vietnam. But until now, only 15 million
people in the country are able to connect to rich digital resources available online, a mere 17% out of Vietnam's 86 million population.
Rural Vietnam, like many other non-urban parts of Asia-Pacific, has very
limited access to broadband Internet. ADSL connectivity is very scarce outside of major cities Hanoi and Ho Chi Minh, and households, businesses
and government offices in rural areas still have to rely on traditional
communication systems - like the telephone and dial-up Internet - with no short term prospect of benefiting from the rollout of broadband
Internet from telecom operators and service providers.
The high operational and capital expenses normally involved in providing
remote villages in Vietnam with high speed Internet means that these
areas face an indefinite wait - perhaps for many years - before telecom operators and service providers reach them.
But the solution to providing broadband Internet access to remote
communities in Vietnam is now underway, thanks to the ADSL connectivity
project - called "VSAT-IP to Bring Broadband Internet to the Countryside" -
initiated by the Department of Science and Technology (DOST) and Vietnam
Telecom International (VTI), the National Service Provider of IPSTAR in
Vietnam. The pilot project implemented in the remote village of Cat Tien
in Dong Nai province has led to a highly cost-effective solution that is now
extending to other villages across the province as well.
The Situation
Rural communities, like Cat Tien, have to overcome major
challenges when it comes to availing high speed broadband
connection. Remote villages are typically far from any
Internet backbone or Point of Presence (PoP). Wired
infrastructure, like fiber optics, usually does not exist or is
unviable to provide ADSL backhaul for far-flung areas. In
addition, the population density in Cat Tien is lower
compared to metropolitan areas, requiring telecom
operators and service providers higher capital and
operational expenses in deploying an ADSL network
infrastructure for the village.
The Solution
The primary focus of the project is to demonstrate that it is both
technically and economically feasible to provide broadband
Internet access to remote communities by using commercially
available satellite technology. The system utilized in the project
uses ADSL technology via Thaicom-4 (IPSTAR) satellite to deliver high speed
Internet access to community residents of Cat Tien. The broadband
Internet connection is distributed among households, businesses
and government offices across the village by deploying a single
IPSTAR user terminal, and connecting it to a Digital Subscriber Line Access Multiplexer (DSLAM) - a network device that can link up to
24 Internet end users to the ADSL network.
The pilot project enables DoST and VTI to provide high speed and
always-on Internet access to Cat Tien, delivering broadband
connection speeds similar to that of major metropolitan cities. The
IPSTAR solution enables the delivery of Internet to various
destinations within Cat Tien - including government offices,
school, medical center, police station and residential homes - with
distances ranging from 200 to 2,000 meters away from the central
node. The shared satellite link is able to provide a download speed
of 2 Mbps and upload speed of 512 kbps.
Proof-of-Concept
DoST and VTI's rural connectivity project in Vietnam is a major milestone in the deployment of ADSL network via satellite backhaul.
IPSTAR plays a major role in the rapid installation of ADSL to far-flung areas, which would otherwise not be economically viable with
fiber optic cable or other broadband backhaul. In addition, the satellite platform helps in reducing the capital expense of the
project to 3,500 USD, a critical factor in the implementation of a sustainable business model.
The pilot project implemented in Cat Tien village demonstrates a valuable case study in addressing a range of issues related to
providing broadband Internet service to remote, isolated areas across Vietnam. The satellite-enabled ADSL network delivers
broadband Internet to thousands of village residents - most of them for the first time.
