The Ericsson Cradlepoint W1855 is the outdoor version of the W1850 — a 5G wideband adapter engineered for external deployment on rooftops, building facades, and remote sites where weatherproofing and temperature tolerance are requirements, not options. IP67 rated and built for -20C to 60C operating conditions, the W1855 handles rain, snow, dust, and temperature swings without degradation. It delivers peak 5G downlink throughput of 3.4 Gbps with 4x4 MIMO, placing the antenna and modem in the strongest outdoor signal position while routing connectivity inside via Ethernet. Four external SMA antenna ports allow additional antenna optimization. Dual SIM with automatic failover keeps the connection stable across carrier outages. Integrates with Ericsson NetCloud Manager and pairs with Cradlepoint SD-WAN routers for a complete managed WAN architecture. Available on GSA Schedule.
