  • Patent number: 10916843
    Abstract: Cellular tower sites generally include a remote radio head conductively connected to a base station. A system for protecting the site from an electromagnetic pulse (“EMP”) includes an antenna array; an EMP detection circuit in communication with the antenna array; and a disconnect switch in communication with the EMP detection circuit. The disconnect switch is conductively connected between the remote radio head and the base station; when opened, it physically interrupts the connection between the remote radio head and the base station. For instance, if a comparison, within the EMP detection circuit, between the pulse duration and/or frequency of an electromagnetic signal received by the antenna array to the frequency and/or pulse duration of an EMP E3 signal component determines a match, the EMP detection circuit can output an EMP detection signal to the disconnect switch, thereby disconnecting the remote radio head from the base station.

  • Patent number: 10499257
    Abstract: Traditional configuration of infrastructure equipment relates to the adjustment of horizontal tilt for antennas. Given the potential overlap of infrastructure equipment, varying tilt angles can result in either interference with nearby equipment (“over-tilt”) or reduced coverage areas within a specific infrastructure equipment (“under-tilt”). A tool for determining appropriate tilt angles for infrastructure antennas across a mobile network is provided. The tool automatically determines a range of tilt angles between a selected source antenna and adjacent antennas and optimizes based on a threshold intersecting point. Additionally, the tool can update calculated tilt angles based on network congestion information.
