BTS is Base trans-receiver station in Mobile communication. It is the base station which receives signals from mobile station. It sends the data or signals to the mobiles.
Communication with spaceships is typically done using radio waves. The spaceship sends signals back to Earth, and vice versa, through antennas on both ends. These signals can carry information such as telemetry data, commands, and communication with astronauts on board.
MODEM (Modulator - Demodulator)modulates Digitals signals to Analog to send over Telephone lines and Demodulates Analog signals in Digital Signals.
Microwaves are ideal for transmitting satellite communication signals because they have a short wavelength, allowing them to carry large amounts of data quickly and efficiently over long distances without interference from the Earth's atmosphere.
The bandwidth of light signals refers to the range of frequencies or wavelengths over which the signal can be transmitted. This bandwidth determines the amount of data that can be transferred over the optical communication system. A wider bandwidth allows for higher data transmission rates.
Electromagnetic wave interference can disrupt communication signals by causing distortion, noise, or even complete loss of signal. This interference can result in poor signal quality, leading to errors in transmission and reception of data.
pragmatic functions are type of communication signals which are used for certain purpose
