The Cradlepoint TAA-170900-017 packages the Ericsson Cradlepoint W1850-5GC for captive modem use in the Americas. Many branch routers sit in closets or basements where cellular reception is weak. With this accessory, the modem can be placed where the signal is strongest while a Cradlepoint router stays the controller. In NetCloud, the W1850 appears as a modem WAN interface with the same Wireless WAN functions as an embedded modem, including Smart WAN Selection, WAN Verify and failover/failback. Deployment, management and licensing go through the router. The part is listed in the accessory tables of the E300, E3000, IBR1700 and R1900 data sheets. The 5GC version uses a 5G FR1 NSA/SA 3GPP Release 16 modem with LTE Advanced Pro Category 19 fallback, dual 4FF SIM slots and 4x4 MIMO. Peak rates reach up to 3.4 Gbps downlink and 550 Mbps uplink in NSA, and up to 2.4 Gbps and 450 Mbps in SA. Dual Connectivity keeps 5G and LTE active at the same time. The low- and mid-band 5G coverage includes n48 CBRS for private networks. Throughput is rated at 2.0 Gbps in captive modem mode. Cradlepoint lists AT&T, T-Mobile and Verizon network operator certifications, along with FirstNet Trusted, T-Mobile Connecting Heroes and Verizon Frontline. The W1850 has a compact 6.5 x 6.5 x 1.5 in housing. It provides two 2.5 GbE LAN/WAN ports, a USB 2.0 port and an RJ-45 console for out-of-band management. Power comes from the included 100–240 VAC supply or from 802.3at PoE+. Four external 600 MHz–6 GHz paddle antennas attach through SMA connectors, and a mobile installation wizard helps find the best placement. The Cradlepoint W1850 datasheet is available as a reference document.
