The Riva Edge 100 operates as a field area network (FAN) access point using IEEE 802.15.4g and Wi-SUN FAN 1.0, standards designed for scalable, interoperable smart metering infrastructure. Its Linux-based compute platform runs locally hosted applications for grid analytics, demand response event dispatching, and outage detection without cloud round-trip latency. Dual WAN connectivity — cellular LTE-M and broadband Ethernet — ensures uptime when one backhaul path fails. The device supports over-the-air firmware updates for itself and its entire endpoint population, reducing truck-roll costs over the meter lifecycle. Full cybersecurity stack includes certificate-based mutual authentication, payload encryption, and IDS anomaly alerts.
