The Federation builds these across its dominated territories to improve communication. The radio stations are usually cheap and disposable, but they do the job. They are usually protected by a single Sentry turret and a few Hoppers. Radio stations can be captured by the player to broadcast a signal. By doing, they reveal their location and lure enemy units to attack the radio station.
