    Coverage to Meet Your Product’s Needs

    The Notecard Cell+WiFi offers a comprehensive suite of coverage options, including a new “midband” LTE Cat 1 bis Notecard alongside our existing LTE Cat 1, LTE Cat M, and NB-IoT options. Each option is offered in North American and Global coverage models, enabling you to customize your coverage to your deployment further.

    To add to this dramatically increased coverage, we’ve included a dual-embedded SIM option that can expand coverage to additional countries and more coverage in those countries while giving you improved reliability and carrier support.

    Unfamiliar with Cat 1 bis?

    LTE Cat 1 bis functions seamlessly within established LTE networks and distinguishes itself by operating efficiently with a single antenna, contrasting with the two antennas required to support LTE Cat 1. This innovation reduces unit cost while making them more compact and more accessible to design.
