Expanding Coverage with Dual-Mode Cellular and NTN Modules

Cellular coverage is likely the most extensive among all other wide-area network (WAN) wireless technologies. However, it still has significant limitations in rural areas (e.g., countrysides, forests or deserts). In addition, it cannot reach offshore sites and the non-coastal expanse of oceans.

A wireless communication module that bridges coverage gaps in remote areas would realize device manufacturers’ and service providers’ dreams. Their aim for ubiquitous coverage is to be able to connect regardless of where assets are installed or where they roam.

The Promise of Dual-Mode Cellular and NTN Modules

Dual-mode cellular and non-terrestrial network (NTN) modules look to deliver this coverage. They promise to connect to terrestrial cellular networks wherever available. They will fall back to satellite connectivity when outside cellular coverage. These modules will ensure continuous, seamless connectivity for IoT devices throughout their life cycle.

The 3GPP Release 17 NTN standard defines a communication protocol that can run on the same modem hardware to exchange data with the cellular network. This protocol leverages the same transmission power level. Therefore, module and device manufacturers don’t need to add specialized, costly radio frequency components to existing cellular products for satellite connectivity.

Moreover, device manufacturers can retrofit current products using a traditional cellular module. They can easily replace it with a dual-mode cellular and NTN module compatible with their hardware and software. As a bonus, manufacturers will benefit from IoT satellite data service and terrestrial wireless connectivity.

Telit Cinterion’s Unified Form Factor Family Approach to IoT Modules

Telit Cinterion is a leading IoT solution enabler. We streamline device upgrades with the latest module technologies. In addition, we reduce redesign efforts for original equipment manufacturers (OEMs). Our unified form factor family approach makes this possible.

This approach enables us to offer modules that are pin-to-pin compatible with the previous generation. These next-generation modules are as interoperable as possible with software interfaces between modules and higher-level applications.

Interchangeable single- and dual-mode cellular and NTN modules empower device manufacturers with greater flexibility. They can mount module variants on different product batches based on specific needs. This ability eliminates the complexity and costs of engineering and managing multiple hardware project designs.
