III. HOW IS SATELLITE COMMUNICATION USED IN MONGOLIA?

• 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).

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• Previously people outside of bigger cities in Mongolia were able to view only four national TV channels due to outdated C-Band system with analog technology which requires big antenna.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.

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.

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.

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