transverses the Internet. See also bridge, circuit, frame, hub, Internet, LAN, link, packet, router, and switch. 3. In radio communications, one skip of a radio wave from an earth station to the ionosphere and back. See also ionosphere, radio, and waveform. 4. In satellite communications, one roundtrip of a signal from an Earth station to a space station (i.e., satellite) and back to an Earth station. See also satellite and signal. 5. In frequency hopping spread spectrum (FHSS) radio communications, a small, quick jump from one frequency channel to another in a carefully choreographed hop sequence. See also channel, FHSS, and frequency.
