Maser

There is more information available on this subject at Maser on the English Wikipedia.

Masers are the primary method of communication on UNSC starships and orbital platforms. They operate by means of emitting microwave radiation; the word "maser" was originally derived from the acronym Microwave Amplification by Simulated Emission of Radiation. Masers are effective for short-range, interplanetary communications, but as they are limited to the speed of light, they are too slow to be effectively used over interstellar distances.
