Satellite Broadband: Product & Tech Requirements

Interested in connecting to Optus' Satellite Broadband service? Find out what you need and what you can do, below. 

What technology is used with Optus Satellite Broadband?

Optus Satellite Broadband is a 2-way satellite service delivering broadband speeds to users within Optus Broadband Satellite coverage areas in Australia. The service provides broadband, by using;

  • Shared broadband digital video broadcasts (DVB-S) for the outroute path(s)
  • Multiple shared frequency/time division multiple access (FTDMA) inbound channels for the request path(s)

Further Satellite Broadband equipment info is available in this article.

What are the minimum computer specs required?


Operating System: Microsoft Windows XP or higher
CPU: 200MHz Intel Pentium Processor
64MB of RAM (or the minimum specified by your version of Microsoft Windows)
Free disk space: 500 MB
Standard Modem Network Device: Ethernet Port withRJ45 socket
CD-ROM drive


Operating System: OS-X 10.4 or higher (Server versions are not supported)
CPU: Power PC G3 or higher
RAM: 256 MB
Free disk space: 500 MB
Standard Modem Network Device: Ethernet Port withRJ45 socket
CD-ROM drive

What's the maximum number of users that can connect?

We support a wired connection to a single computer. The use of a Local Area Network (LAN) for personal use is permitted, however the set-up and configuration of a LAN connected to the Satellite Modem is best effort only. Optus recommends a maximum number of 4 to 6 users sharing a Satellite Modem due to the limitations of the acceleration software.

Can I provide network services or host a web server?

Running network services or hosting a web server are not supported and or permitted under our Acceptable Use Policy check it out here, It's recommended that customers with web servers use an off site/remote hosting service.

Speed & latency

while there is latency with a broadband satellite service, Optus uses acceleration software to mitigate any delay attributable to the distance that the satellite signal must travel.

Using this software, Satellite Broadband can deliver a service comparable to and, on occasions better than, a terrestrial broadband service. Without the acceleration software, you may experience between 500ms and 1500ms of latency when using a Satellite based service.

IP Addressing, VPNs & NAT

Is Network Address Translation (NAT) supported?

Unless you've requested a Public IP address your Satellite Broadband service will use NAT. NAT is configured for your service at the Optus Satellite Hub. NAT provides basic protection from unauthorised intrusion from the Internet.

Are Virtual Private Networks (VPNs) supported?

Yes. To support a VPN, you'll need to request a Public IP address. You should note that TCP acceleration and Internet Page Acceleration software is used in the satellite equipment to improve your broadband speed. If you encrypt each IP packet, for example using IPSec, TCP acceleration and IPA is unable to operate, slowing upload and download speeds.

However some Internet Security systems encrypt only the IP packet payload leaving the header un-encrypted. These systems allow TCP acceleration and IPA to operate effectively.

Are Public IP addresses available?

Yes however this is special request that you will need to make prior to installation. There may be an additional charge to provide a Public IP address. If you use a Public IP address for your site it's highly recommended that you implement additional security such as a firewall.

Can I use my current Public IP address?

Yes however this is special request that should be made to your Optus sales representative. This may incur an additional cost.

Do I need a Public IP address?

A Private IP Address is not visible from the internet. Therefore applications which require visibility from the Internet or do not work with Network Address Translation (NAT) require a Public IP address. If such functionality is required then you should request a Public IP address. If you use a Public IP address for your site it is highly recommended that you implement additional security such as a firewall. See Online Safety for more information on Internet security.

Do I get a static or dynamic IP address?

Your IP address is allocated to the equipment at your premises (Computer or other equipment) by the satellite modem dynamically each time the equipment is switched on. Normally the same IP Address (Public or Private) is allocated each time you boot up. However Optus may change a Private IP address at any time. All IP addresses provided by us for your use remain our property.

What's the difference between static and dynamic IP addressing?

A static IP address is one that is manually allocated to the customer's equipment and remains the same unless manually changed.

A Dynamic IP Address is an IP Address dynamically allocated to the customer's equipment upon boot up. In some cases dynamically allocated addresses change with each boot-up. With our Satellite Broadband, a Public IP address will always remain the same while a Private IP address normally remains unchanged.
