Media heir Ryan Stokes has thrown his support behind the national broadband network (NBN), which he says will give greater access to those in remote locations to a range of video, print and oral records held at the national library.
Bandwidth pertains to the amount of data that is sent and received by ISPSs and satellite broadband companies. This amount is measured in terms of megabits per second, or roughly one million bits per second.
There are approximately 300 satellites located on a fixed geostationary orbit, just above Earth’s equator, with 2-3 degrees distance in between. These satellites move withthe world at the same speed. Ground stations can locate geostationary satellites at a fixed location relative to the globe’s equator.
Three things should be carefully considered when evaluating the capacity of satellite carriers: downlink EIRP power (dBW), transponder bandwidth (MHz), uplink G/T (dBK) and sensitivity (dBW/^m2), which is bought by ISPs and satellite operators.

The 2012 NewSat Satellite Seminar, held at the company’s South Australian Teleport facility, has attracted 50 industry leaders from defence, government and satellite communications sectors. The participants gained insights on industry trends and growth prospects of the Australian market. Australia is poised to become a major global player in the satellite service market given its secure and unique communications networks and facilities.
Marc Legare, chief executive officer of US-based Proactive Communications, discussed how the defence sector is fuelling the growth of the global satellite communications market. Legare noted that the competitive edge of the Australian satellite industry lies in the country’s geopolitical status, safe environment and availability of satellite infrastructures with global coverage. Proactive Communications has partnered with NewSat to provide satellite communications services for the US armed forces deployed in the Middle East.

Australian satellite communications services are evolving rapidly. The advent of satellite VoIP makes Internet telephony even more reliable and accessible. People who live in remote areas and those who travel to inaccessible places can enjoy a wide VoIP coverage with satellite Internet.
Thanks to the development in IP networking, transmitting calls via the Internet has become possible. As VoIP becomes more integrated with satellite services, satellite VoIP providers have expanded their products to better serve both the business and consumer markets.
The Geeveston ground station, expected to be operational in 2013, will be a single storey building with two 13.5-metre diameter satellite dishes, and will help service between 15,000 and 20,000 Australian homes and businesses with broadband speeds of up to 12 megabits per second.
Telstra will stop tracking Next G customers’ web browsing history and sending that data to the United States, following criticism from the public relating to privacy issues.
