Cambium cnPulse Sync Generator
TDD Synchronization is critical for deploying dense scalable wireless networks, whether in a PTP or PMP topology. One typical source for synchronization is the GPS satellite signal which carries a precise one pulse per second (1PPS) clock. Using this clock, PMP and PTP networks can synchronize the start and stop time of all transmissions. By synchronizing the transmit and receive signals, each AP or Access Point isn’t transmitting while its neighbor is receiving, thereby reducing self-interference, increasing spectral efficiency and enabling much more dense network deployments.
cnPulse is the latest GPS synchronization generation device designed specifically for Cambium Networks PMP and PTP radios. The cnPulse module is IP67 (weather proof and supports a wide temperature range for rugged environments. The GPS receiver is highly reliable and supports both GPS and GNSS signals. cnPulse gets it power from the ODU AUX port in mode 1 or from the CAT-5 drop cable in mode 2 so no external power supply is required. There are no configuration or software settings required.
cnPulse can be deployed in two alternative ways as shown in the table below. Note that a single cnPulse can provide synchronization to two AP’s by leveraging mode 1 on the first ODU and mode 2 on the second ODU.
