The inclusion of communication subsystems into an over-all systems plan has placed a challenge to deliver squarely on the Communication System Engineer. There are still several areas that require considerable work before they can be considered in line with individual subsystem requirements. One of these is data transmission, another is reliability. Systems such as the US Air Force 480-L or programs like the US Army´s UNICOM will furnish him the over-all design criteria and common facilities. However, for some time to come, special problems of the type listed will continue to be solved concurrently with the development of the individual subsystem where the solutions are most urgently needed.
