Abstract
Abstract A method of automatically determining the reliability of any LOS radio link given certain parameters. Specifically, this method allows a communications network operator to specify and determine the path reliability (PR) for each backbone and extension link in a communications network for a given operating frequency, path length and climatic factor. For each link, the fade margin required (RFM) for a desired path reliability (PRD) is calculated. Then, the actual fade margin of the selected link is calculated using known radio parameters. Preferably, these known radio parameters are stored in a database to facilitate access to this information. Then, the corresponding value of the actual path reliability for the link is calculated using modifications of known statistical models which take into account climatic and geographic factors.

Claim 1
Independent Claim
187 words
An improved terrestrial, line of sight radio linked network having a predetermined number of terrestrial, line of sight radio transmitters and receivers, the terrestrial, line of sight radio transmitters and receivers having predetermined physical parameters and known multipath fade margin capabilities and being spaced over a predetermined distance and terrain, the improvement comprising: an automated system and software program which automatically calculates a required multipath fade margin given a climatic factor, radio wave path inclination, desired reliability and radio frequency for each terrestrial, line of sight radio link; means within the automated system and software program to compare the required multipath fade margin to the multipath fade margin capabilities; means to alter the predetermined physical parameters of the terrestrial, line of sight radio transmitters and receivers if the difference between the multipath fade margin capabilities and the required multipath fade margin is less than or equal to zero; and means to alter the predetermined distance between the terrestrial, line of sight radio transmitters and receivers if the difference between the multipath fade margin capabilities and the required multipath fade margin is less than or equal to zero.
