Abstract

While a number of features make fixed wireless access (FWA) technology a candidate for effective high bandwidth network infrastructure solutions, several factors, primarily heavy rainfall, can hamper the availability of a FWA link. To overcome this pitfall, a possible solution is using backup wired routes for most critical/vulnerable segments of the FWA network. In this paper we propose a parameterized configuration model for a switch operating with a primary (FWA) route and secondary (ISDN) backup route. We use data collected during an approx. 3 years experiment to study the impact of the parameter settings and determine optimal configuration in order to maximize the overall system availability.
