As it turns out, the hottest real estate market may be one we can’t see. Everything from space exploration signals to HAM radios are vying for room on the radio spectrum, in which frequencies range from 3Hz to 3,000GHz. This spectrum acts as the “transportation system” for all wireless communication, and blocks of it are divvied up for specific uses. This infographic illustrates the complexity of this allocation system.
Plots of “Land” on the Frequency Band
Nearly all of the radio spectrum is already divided into a number of civilian and military uses. Some of the most prominent blocks (turquoise on the map) are set aside for television and radio broadcasting, as well as various types of navigation and satellite communications.
The spectrum also has a number of blocks dedicated to amateur radio and satellite.
