VSAT operate at one of the following frequencies: C band, Ku band, or Ka band. C band operation requires a larger satellite dish due to its lower frequency; Ku band dishes are smaller in size and more vulnerable to rain-fade than C band dishes. Ku band dishes are more widely used. The satellite dish, parabolic in shape, is mounted in any area.
Combining multiple links into a single pipe with the combined aggregate throughput of both links into one.
A block up converter (BUC) is used to transmit signals to satellites. It converts a low IF frequency signal to higher frequencies for transmission to a satellite. When selecting a BUC, you must consider the following parameters: Input/IF Frequency and Output/RF Frequency.
LNBs are down-converters, the receive section of the equipment. LNB has two important functions: it's a low-noise amplifier, meaning that it takes the extremely weak satellite signal and amplifies it. Both functions are important to deliver a satellite signal through a regular cable.
The modem used in VSAT application is referred as VSAT modem. It is also known as satellite modem. There are different bands of VSAT modem available based on IF frequencies of use in its construction.
