Outage probability computation and cellular coverage for mobile radio

Abstract
This paper presents two new methods for computing the outage probability of a cellular land mobile radio system with narrowband modulation and digital transmission of speech. They are well suited to compare different system solutions, since they take into account the main characteristics influencing the transmission performance, i.e., modulation method, power control, antenna radiation patterns, space diversity, adjacent- and co-channel interference arising from the frequency reuse, propagation impairments due to log-normal shadowing fading and to fast Rayleigh fading. The paper reports some computations of the long-term median value of the useful to interfering signal ratio vs the position of the useful mobile unit in the service area. It gives the frequency reuse configurations acceptable according to the presented outage probability methods relevant to different mobile radio systems and compares the pertaining telephone traffic efficiencies.
