HOW YOUR LINK-SAT TERMINAL WILL WORK
The Link-Sat terminal comprises of an outdoor satellite dish, similar to that of a satellite TV system which is connected to an indoor modem using two coaxial cables. Your own computing equipment (PC, router etc) is connected to the modem using a common CAT5 10/100 Ethernet cable.
Outdoor equipment comprises a parabolic antenna reflector and receive and transmit radio modules in front of the dish. Antenna sizes are 1.2m, 1.8m and 2.4m diameter. Larger sizes are required at the edges of the satellite beam coverage. Transmitter powers are 2 or 4 watts. The network coverage map shows the needed dish size and transmitter power required to achieve guaranteed service.
| The indoor unit, which is sometimes called the Return Channel System Terminal (RCST), is a small box approx 13.1 inches wide, 7.53 inches deep and 1.7 inches (1U) high. It may be rack mounted using small brackets on either side. For reliable operation, put the RSCT in a cool, clean, dry place away from direct sunlight. Apart from the initial set up, the RCST requires no customer maintenance. At the back of the box are two F connectors for coax cables and a socket for a main lead (IEC type). The system power requirement can uses 115 to 230 volts. |
|
| There is also an 8 way RJ45 socket for your CAT5 10/100
Ethernet cable to plug in. The equipment is fully compliant with
international DVB-RCS standards and is commonly used worldwide.
Download high speed data streams received from the satellite are
analyzed and demodulated by the RCST circuits and the bandwidth intended
for the specific customer terminal is delivered to the customer
computing equipment via the Ethernet interface. |
