Final answer:
Microwave technology was implemented by cable companies for communication purposes, as microwaves can carry more information per unit time on high frequencies. Most satellite-transmitted information and land-based long-distance transmissions are carried on microwaves.
Step-by-step explanation:
Microwave technology was implemented by cable companies for communication purposes. Microwaves are suitable for communications because they can carry more information per unit time on high frequencies. Most satellite-transmitted information and land-based long-distance transmissions are carried on microwaves. However, a clear line of sight is needed between the transmitter and receiver due to the short wavelengths involved.
