Cisco Radio Modem: LoRaWAN Wireless Gateway

The Cisco Radio Modem is a high-performance LoRaWAN wireless gateway engineered for demanding IoT deployments across industrial facilities, smart cities, and enterprise environments. Built on Cisco’s trusted networking foundation, this gateway delivers secure, scalable connectivity for thousands of devices, combining enterprise-grade reliability with the flexibility required by modern IoT applications. It supports LoRaWAN Class A, B, and C device types, enabling a wide range of use cases—from low-latency control loops to energy-efficient sensor networks. With Adaptive Data Rates (ADR), spreading factor optimization, and channel diversity, the modem maximizes network efficiency while extending device battery life and ensuring robust coverage in complex RF environments. Integrated GPS time synchronization further aligns network timing, enhances geolocation capabilities, and supports precise event sequencing across distributed assets. For organizations seeking accurate device localization, the hardware-assisted geolocation features—TDOA (Time Difference of Arrival) and RSSI-based trilateration—deliver actionable insights without adding software complexity. Available in two dome-ready models, this gateway is designed to fit a variety of installation scenarios while delivering Cisco-grade security, manageability, and performance.

How to install Cisco Radio Modem

• Plan your network topology and determine optimal gateway locations to maximize coverage while minimizing RF interference. Confirm regulatory compliance for your region and prepare a suitable power supply and grounding scheme.
• Mount the modem in the chosen dome or enclosure and connect the required backhaul (Ethernet or other supported uplink) as specified by your model. Attach the GPS antenna if geolocation accuracy is a priority and ensure clear line-of-sight where applicable.
• Power on the device and access the management interface via the provided IP address or console. Complete initial configuration by selecting your LoRaWAN network server, setting device classes, enabling ADR, and configuring time synchronization parameters if GPS is available.
• Register the gateway with your LoRaWAN network server and define security credentials, network keys, and device addresses. Configure geolocation features, including TDOA or RSSI-based trilateration parameters if you plan to use location services.
• Perform a validation and health check: verify uplink and downlink performance, confirm gateway visibility to network servers, and test geolocation accuracy by locating a known reference device. Review logs for any anomalies and apply firmware updates as needed for optimal security and performance.
