RADIO SUBSCRIBER NETWORK EMPLOYING AN AIRBORNE TRANSPONDER.
Abstract
This report explores in greater detail the Random Access Discrete Address (RADA) subscriber net concept set forth in ICS-63-TR-199. A second approach, the Multiple Frequency Discrete Address (MFDA) technique, is also considered for this application. A RADA network employing a single address for transmission and reception permits the use of a simple operational procedure, provides a ready conferencing capability and requires the smallest address matrix. In more sophisticated systems employing feedback loops for error correction or system signalling and control, however, a two-address system is required. This increased flexibility can be provided in a two-address system with little increase in equipment or operational complexity. Use of the two-address system also permits choice of either manual or automatic means for determining a busy line or a busy subscriber condition.
