Satellite communication uses satellites to relay radio signals between a source and receiver. There are over 2,000 communication satellites in orbit used by private and government organizations. The document discusses how satellite communication is used in Mongolia, noting that DDISHTV was established in 2008 to broadcast more television channels to rural areas using Ku-band technology and small satellite dishes. DDISHTV uses the Apstar 5 and Telstar 18 satellites to broadcast over 50,000 customers across Mongolia and parts of Asia.

14. III. HOW IS SATELLITE COMMUNICATION
USED IN MONGOLIA?

15. • A member of the Asia-Pacific Broadcasting Union (ABU),
DDISHTV was established in January 2008 to carry out
Mongolian government’s proposal to broadcast more
television channels in the countryside in high quality.
It has officially started broadcasting in June 2008.
• DDISHTV (Mongolian: ДДэшТВ ХХК) is a Mongolian satellite
TV and Internet provider company led by Ganbold Dendev
(CEO).

16. BACKGROUND
• Previously people outside of bigger cities in Mongolia
were able to view only four national TV channels due to
outdated C-Band system with analog technology
which requires big antenna.
• DdishTV began to work as first and unique operator
with more TV channels to the consumers
across the country through latest Ku-Band technology
which allows small dishes.

17. COVERAGE AREA
• As of April 2013, DdishTV broadcast across Mongolia for
over 50,000 customers, though the reception is also
available in over 25 different Asian countries, such as
Russia, China, Korea, India, Afghanistan, Pakistan,
Bangladesh, Kazakhstan, Iran etc.

18. SATELLITE LINK
• Ddish TV uses Apstar 5. Telstar 18 broadcast its programs.
Telstar 18 was launched in June 2004 by Sea Launch, as a replacement
satellite for APSTAR-I.
It has an estimated operational lifetime of over 15 years.

19. • In 2020, the Internet, digital television technology-based
services through its satellite is a company leader in the
national cause, regardless of the distance.
