Rational radio reliability rendition

Reliability engineering has generally concerned itself with system failures caused by catastrophic failures of components. Given a stable system and known environment, existing technlques may give accurate predictions of the reliability of electronic systems. When mobile communication systems are analyzed, however, the available propagation conditions presented to equipment operated under extremely variable environmental conditions may cause reliability predictions to be quite inaccurate. The factors affecting actual reliability are discussed; means are examined for designing mobile communication equipment to achieve optimum results in each of these areas. Finally, a specific equipment design built around these techniques is discussed and life testing under simulated environmental conditions is examined.
