Interface tests coverage for multiple carriers as part of our solutions engineering and during our installation process in order to deliver the best service for each location. Should we identify a location with patchy coverage, as part of our installation we will test multiple carriers so we can provide the best coverage for that location.
We can design a solution that incorporates a second cellular carrier and use both carriers in an active-active connection configuration. We can add terrestrial broadband as backup should the primary carrier network not be available. The Wireless WAN router can be configured to use the best, or only active, carrier to route traffic whether it is LTE/5G or terrestrial broadband.
