A new simplified model has been developed for making reliability evaluations of radio base stations and enclosed equipment. Components are grouped into families since individual component types are difficult to study in the field due to a low failure rate. A failure rate interval is assigned to each component family based on operational field data from Ericsson telephone equipment. Critical families can be pointed out as a base for reliability improvement programmes.
