Why Operators Choose the NB Series

Global Multiband Cellular Connectivity

Supports LTE Cat M1 and NB-IoT multiband to ease deployments across regions and reduce dependence on additional local infrastructure.

Designed for Challenging Environments

Signal penetration helps maintain reliable connectivity in demanding locations such as basements and high-rise buildings.

End-to-End Security

Integrates NXP DESFire EV3, AES-256, and mutual TLS to the cloud, with cloud infrastructure options including AWS, Azure, and on-premises deployment.

Less Field Maintenance

Ultralow 14 μA consumption and a typical 18-month battery life help reduce maintenance interventions.

OTA Updates and Remote Management

OTA updates keep the firmware current without frequent site visits, simplifying management of distributed installations.

Lower Operating Cost

Robust hardware, cellular connectivity, and remote management help reduce total operating cost as the number of doors grows.
