|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.
