101 Technology Frequently Asked Questions How much faster is satellite than dial up? A standard Dial up has a maximum speed of 56kbps using a telephone line, 128kbps with ISDN. For example, a satellite service with 512kbps download speed is approximately 10 times faster then standard dialup. Is it a broadband connection? Yes, Satellite connections in Australia are considered broadband if the connection downloads at speeds 256kbps or over. How does it work? A modem is plugged into a Network interface card inside your PC or MAC. The modem is then plugged into the satellite dish mounted on your roof. Your Internet requests are transmitted to the earth station via the satellite dish, which bounces off an orbiting satellite. The requested traffic is then returned to you via the same data path. The service maybe plugged into a home or office network for Internet sharing between computers in your LAN (local area network) however this is not part of the standard installation process. Is the satellite always on or do I need to dial it up? Satellite services are an ‘always on’ connection irrespective if the computer is switched on or off. Our Satellite connection is a Two-way service and therefore does not use a telephone line or dialup connection. You may switch the modem off when not in use if required. Does this service require a line of sight or have distance limitations like other Broadband products? The only line of sight required is a line of sight to the satellite in the sky, some areas with dense trees may have an issue receiving a signal. Other than that the service is available virtually everywhere in Australia. I have heard satellite has a lag (latency), is this true? For standard usage like browsing and downloading there is only a slight lag compared to other broadband products thanks to some technical prioritisation performed through the modem. For applications that require high-speed ping times like Virtual Private Networks or Terminal Services, there is a lag typically of around 600 milliseconds due to the distance needed to travel, some 70,000 kilometres. How big is the satellite dish? The standard service has an 84cm – 1.2mtr satellite dish that is mounted on your roof. In some areas of Australia a 1.8mtr dish is required. Can I install it myself? No. This Satellite service requires an experienced technician with specialised equipment to install the system.
