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.

Abstract: A dynamic and expandable communication tower monitoring unit includes a set of programmable modules for returning information about the electrical, environmental, structural, and communications status of a cellular tower, its components and ancillary service and carrier equipment. The monitoring unit processes programmable analog, digital, thermistor, voltage and trending inputs. Key features include an accelerometer-based structural sensor (“twist and sway”), a grounding integrity system for multiple tenants, and a second secure-feedback module (“watchdog circuit”) that provides an extra layer of protection in case of the system-wide electrical and/or communications failure. An operating system provides a series of control screens that allow for remote and local control of input and output variables for each tower.

Abstract: A cellular fiber monitoring module (CFMM) for a remote cellular tower site is implemented by providing monitoring for fiber connections between mobile carrier's broadcast ground equipment and its corresponding antenna equipment located on the cellular tower. Each monitoring module includes a fiber optic monitor pass though module which integrates the necessary monitoring data for each base transceiver station (BTS) equipment including, fiber port pass/fail status, peak to peak level measurement, optical degradation, BTS fault status, etc. The CFMM can be used as a stand-alone device or integrated into an on-site monitoring system.
