F. alternator systems to obsolescence. f. beam system, which, when fully developed, was to become the backbone of long distance point-topoint radio communication and remained so until the comparatively recent advent of satellite techniques. f. system encouraged research into the even higher frequencies as potential message-carriers and this led in turn to the development of valves which would oscillate at these frequencies. f. f. point-topoint multichannel links. Other new communication methods introduced include the ionospheric and tropospheric scatter systems, but by far the most significant innovation of recent years has been communication via satellite.
