C-band frequencies (3.4-4.2 GHz) are vital to operations of satellite services, particularly intropical and subtropical regions, where other frequencies are bedevilled by “rain fade”.

Societies in the Asia-Pacific rely on C-band to support business communications, telemedicine, distance education, disaster recovery – and, of course, getting broadcast content to the region’s 575 million pay TV homes.

But other groups have their eye on the C-band frequencies.

Several administrations have already assigned portions of that band for wireless broadband systems – with disastrous results. Now the ITU is being asked to open the C-band for use by 4G and future 5G (IMT) wireless systems.

AVIA and its members are fighting back against this invasion. Click on the documents below to get educated and, if you are a pay TV operator, ask your engineering people if you rely on the C-band to get the programming you and your customers need. Then contact your national telecoms regulator, and let them know that C-band is vital for your business and your links with the rest of the world.

Fight the Invasion!

If you’re a user of satellite C-band services, contact your regulator.

Who Uses C-Band? Tens of millions of C-band dishes serve hundreds of millions of Asian households and businesses.

One of the most important uses is distributing broadcast programming to millions of TV reception dishes (TVROs). For a broad overview of this aspect of C- band usage across Asia click here.
