Microwave/P2P

Microwave is a kind of electromagnetic wave, microwave system is use as a transmission of information from one point to other point, and microwave frequency range is from 300MHz to 300GHz. Microwave technology is extensively used for point-to-point telecommunications (i.e. Non-broadcast uses). Microwaves are especially suitable for this use since they are more easily focused into narrower beams than radio waves, allowing frequency reuse; their comparatively higher frequencies allow broad bandwidth and high data transmission rates, and antenna sizes are smaller than at lower frequencies because antenna size is inversely proportional to transmitted frequency. Microwaves are used in spacecraft communication, and much of the world's data, TV, and telephone communications are transmitted long distances by microwaves system.
