What is the formula for data rate?
Plug the amount of data (A) and transfer time (T) to solve for the rate, or speed (S), into the equation S = A ÷ T. For example, you might have transferred 25 MB in 2 minutes. First, convert 2 minutes to seconds by multiplying 2 by 60, which is 120. So, S = 25 MB ÷ 120 seconds.
What is data rate in satellite?
The data rate direct-to-Earth varies from about 500 bits per second to 32,000 bits per second (roughly half as fast as a standard home modem).
What is data rate in communication?
The data rate is the number of bits transmitted from one device to another or over a network per second. Data rates are usually expressed in bits per second or bytes per second.
How is satellite transponder bandwidth calculated?
If you choose 8-PSK modulation, your symbol rate will be 682.67 / 3 = 227.55 k symbols per second. The amount of transponder bandwidth needed for a 227.55 kbit/s carrier is about 1.2 to 1.4 times the symbol rate. I assume 1.35 below. the bandwidth needed is approx 1.35 x 227.55 = 307 kHz.
What is the bandwidth of satellite communication?
High bandwidth. A Ka-band (20-30 GHz) satellite can deliver throughput at gigabits per second rates. Inexpensive. A satellite communications system is relatively inexpensive because there are no cable-laying costs, and one satellite covers a very large area.
