All power company rely heavily on electronics to monitor hi power flow. plants output on a distribution level electronics are used to open-close breakers. up to the minute reliable communication is essential a loss of 100 costumers means a loss of bigrevenue's Some company rely on modems and their own telephones lines others use satellites. Converting a state California to new communication without interruption is a concern
bus
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.

The purpose for having communication satellites in space, is by providing telecommunication throughout the world. Communication satellites are mostly used for mobile phone signals, weather tracking, and broadcasting television programs.
radios,satellites, satellites phones,ham radio are the various communication facilities during disasters
man made satellites are used to orbit around the earth. these satellites collect information that can be used for communication, defense, weather forecasting, research etc..
The purpose of communications satellites are to provide telecommunication for companies around the world. In addition, communication satellites are also used for mobile applications such as communication to ships, vehicles, and planes.

Rockets have been used for space exploration to send satellites and spacecraft into orbit, for military purposes such as missile defense systems and intercontinental ballistic missiles, and for commercial reasons like launching communication satellites and cargo into space.
Wheather satellites are used to take close pictures of the earth . Communication satellites are used for communication. Ex(in the old days if you sent a letter from Canada to Russia it would take 25 days. Now you write in MSN, it goes to the satellite and to the reciever.)
It is used for communication plates where geostationary satellites can't reach, in polar areas. Russia uses elliptical satellites where the geostationary satellites can't reach.
The two main types of satellites are communication satellites, which are used for transmitting signals for television, internet, and telephone services, and Earth observation satellites, which are used for collecting data about the Earth's surface, atmosphere, and oceans for various purposes such as weather forecasting and environmental monitoring.
Satellites are launched into space for a specific job. Most commonly satellites are used to support communication, such as TV and provide source for phone cells.
