Microwave
• It is the waves that penetrate the atmosphere to the outside world. For
microwave on earth is traveling in a straight line nor bend the crust. It can
signal a distance of about 20 miles. If there is a need to send in the long distance,
it need to act dish to get to the next repeater distance away.
• The disadvantage of the microwave signal is can easily be disrupted by electromagnetic waves. Including climate variability can affect communications systems.
