Cradlepoint CBA750B Router Only (Refurbished)


This Cradlepoint CBA750B Router is ready for any Cradlepoint LP, and LP-ARC, modem. Officially known as the ARC CBA750B, it can also use many 4G LTE modems by Sierra Wireless via its 2x USB interfaces.  The Cradlepoint ARC CBA750B makes it very simple to manage multiple cellular modems as well as multiple SIM cards for each modem for fail-back and fail-over cellular connectivity. This is the predecessor model to the CBA850.

The Cradlepoint CBA750B integrated mobile broadband series adapters enable easy-to-install wireless WAN connectivity in fixed-business locations. For distributed enterprises like branch offices, retail stores, restaurants, and small businesses, the CBA750B provides 3G/4G wireless network connectivity to keep your business up and running

Engineered for day-in, day-out 24/7 Internet connectivity, the integrated business series products extend the benefits of WiPipe technology across the router and the modem, ensuring reliable connections when you need them. In router mode the CBA750B has access to most of Cradlepoint’s powerful suite of routing capabilities. Power-over-Ethernet enables flexible mounting location, and external high-gain antennas ensure optimal performance in areas of low signal strength.
