Proof-of-performance testing

Proving that a system performs as specified, proof-of-performance testing, presents a series of problems. Two different approaches to providing for proof-of-performance (POP) testing are discussed. It is shown that the required system gain can be reduced based on the conditions placed on the POP. The principal problem in the mobile communication systems is the occurrence of large areas with little or no signals in the desired covered area. One method of testing would be to allow one test at a single point. If the test fails, tests would be made at the corners of a box around the point, etc. In this manner, the size of the hole in the coverage area could be determined, and the necessary action taken
