Microwave is a "line of sight" system, so the two points must be able to "see" each other. If they're linked by satilite, that can be around the world, and if by microwave towers then as far as you can see the tower.

Which vacuum based device is widely used as a power amplifier in satellite communication system?
The Traveling Wave Tube Amplifier (TWTA) is widely used as a power amplifier in satellite communication systems. It amplifies signals in the microwave frequency range and is capable of providing high power output with low noise and distortion. TWTA technology has been utilized for several decades in satellite communication due to its reliable performance and efficiency.
Applications of tunnel diode?
Applications: They are used in low power amplifiers DLVA, microwave and RF power monitors, high-frequency triggers, ALC loops, zero bias detectors, ACP tunnel diode circuits, etc. Since they are more resistant to nuclear radiation, tunnel diodes are used in space applications like amplifiers for satellite communications.
Why high frequency is used in communication than low frequency?
High frequency is used because of the the size of antennas used to transmit and receive the communications signal. The higher the frequency the smaller the antenna.
What is the frequency range used in wireless communication?
2.4GHz is used & OFDM
Do cell phones use radio waves or microwaves?
Microwaves are radio waves.Technically, "microwave" is the term used to designate radio communication onfrequencies above 3 GHz. Cellular and mobile data service doesn't operate inthat frequency range. But microwave systems operating in bands between5.8 GHz and 80 GHz are used to link the individual cellular and mobile data sitesto each other, and to the mobile switching centers.
What is microwave and satellite communication?
AnswerThe term microwave is associated to electromagnetic waves of frequency of the order of MHz .Since the energy carried by the wave is directly proportional to their frequency they are of great use in distance communication. For a simple microwave communication system, a radiator ,a reflector and one receiver antenna are essential. As the wave penetrates through the atmosphere a satellite reflector is usually used. Satellites use Microwaves to send signals.
What is microwave satellite communication?
It is communication with a satellite orbiting the planet using microwaves, a type of electromagnetic wave of lower frequency than light but higher frequency than radio waves. Microwaves are often used in this way as they can penetrate the earth's atmosphere, but can travel a long enough distance to reach the satellites, unlike x ray waves.

Define downlink frequency?
In the sense of a mobile communication: Downlink frequency is that used by a base station to communicate with the Mobile. In satellite communication also the same theory exists downlink is the return path.
In what products do microwave tubes find application?
Microwave tubes were primarily used in high and ultrahigh frequency applications such as radars, telecommunications equipment, military communication and control systems
What is up converter in satellite communication?
Every information sent and received through satellite communication has to have an address to enable the communication process of signal delivery and reception. This naming of the signal is made in the form of a specific frequency. For example each TV channel operates on a unique frequency of it's own. When that frequency is called (tuned technically) out of a spectrum in that band, the chosen frequency gets selected. Since satellite transponders operate at very high frequency, modulation of the signal on to the carrier is difficult. Hence modulation is carried out at a much lower frequency. Such modulated signal is raised to the required frequency( name or address as stated above) that supports the satellite band and the transponder. The equipment used to elevate the frequency of the low frequency carrier (known as Intermediate Frequency) to the satellite transponder frequency is UP CONVERTER C.K.Vasudeva Bangalore
What is frequency of a satellite wave?
I never heard of a "satellite wave". If you mean the radio waves used by satellites for communication - well, like all radio waves used for such purposes, there is probably a large range of waves they can use.
What are microwave systems used for?
Microwave and satellite systems can be used to transmit audio, video, and other forms of data
What are satellite systems used for?

Why vacuum tubes are not preferred at microwave?
Actually three special purpose vacuum tubes were specifically designed for microwave usage and are in some cases still the least expensive way to work with high power microwave signals.These vacuum tubes are:cavity magnetron (first designed in WW2 for use in military RADARs, still used in some RADAR systems and as the microwave radiation source in all microwave cookers)klystron (still used in satellite communication, medical microwave equipment, and particle accelerators)traveling wave tube (still used in satellite communication, RADAR systems, and the electromagnetic compatibility (EMC) testing industry for immunity testing of electronic devices)
What type of antenna is used for satellite communication?
parabolic
What is agila2?
Communication Satellite, launch and used by Philiipines
