Abstract: Systems and methods for monitoring passive components of a passive public safety distributed antenna system are provided, including a bi-directional amplifier, a public safety monitor coupled to and in communication with the bi-directional amplifier, and at least one smart node coupled to and in communication with the public safety monitor. The at least one smart node includes a processor configured to monitor signal characteristic information of at least one passive component of the system and transmit the signal characteristic information of the at least one passive component to the public safety monitor. The public safety monitor generates system performance information based on a signal at the bi-directional amplifier and the transmitted signal characteristic information of the at least one passive component from the at least one smart node.

Abstract: Disclosed are devices, systems, apparatuses, methods, products, and other implementations of GNSS repeater systems and methods for improving phase and frequency alignment of RF signals transported through fiber optic communication channels. Acquired RF signals are processed at a remote outdoor unit, where they are digitized, formatted into a CPRI frame, and timestamped. The timestamped CPRI frame is then transported over a fiber optic communication channel to an indoor head end unit. The indoor head end unit extracts timestamp and digitized RF signal from the CPRI frame. The timestamp is then used to synchronize a base transceiver station (BTS) and a precision time protocol (PTP) grand master with the remote outdoor unit.
