| Consider the following statements |
| 1. Very Small Aperture Terminal systems can use both C and Ka-bands to transmit signals. |
| 2. VSATs are used only in the transmission of narrow band data. Which of the statement(s) given above is/are correct? |
A) Only 1
B) Only 2
C) Both 1 and 2
D) neither 1 nor 2
Correct Answer: A
Solution :
[a] A very small aperture terminal (VSAT) is a two-way satellite ground station with a dish antenna that is smaller than 3 meters. VSATs are used to transmit narrowband data (e.g., point-of-sale transactions using credit cards, polling or RFID data, or SCADA), or broadband data (for the provision of satellite Internet access to remote locations, VoIP or video). VSATs are also used for transportable, on-the-move (utilising phased array antennas) or mobile maritime communications.
