Totum leverages its DMSS technology to connect end point devices around the world. Totum manages everything from the modem inside the DMSS SOC (System-on-Chip) to the constellation of Low Earth Orbit satellites, and back down to our series of ground stations around the world.

Our infrastructure enables our solution provider partners to design devices using our SOC, and then utilizing our connectivity over the Totum DMSS Network to connect those devices globally. A visual of the DMSS Network is provided below.

Many satellite IoT solutions require endpoints to be placed within meters of network-connected gateways with bulky antennas pointed at the sky. In contrast, the DMSS Network is Low Power Sensor-to-Satellite (LP-S2S) connectivity where communication is direct from the endpoint to the satellite constellation anywhere on earth in real-time and with no gateways required.

The DMSS network provides global coverage (including indoor), lowest cost, longest battery life, location not reliant upon GPS/GNSS, and an overall simplicity unmatched by any Low Power Wide Area (LPWA) connectivity.

Continue reading to see why Solution Providers are choosing Totum’s DMSS Network for their LPWA connectivity needs.


DMSS3990 integrated System-on-Chip enables a cost-effective solution including an integrated on-chip ARM Cortex M0+ application processor.

Unlike private network solutions such as LoRa, no network infrastructure required.

DMSS connectivity subscription priced to win over any other competing LPWA connectivity.


The DMSS Network provides seamless global connectivity. Unlike NB-IoT, there are no roaming agreements to manage or the possibility that NB-IoT is not available in a region your devices may land.


The DMSS3990 System-on-Chip (SOC) employs state of the art silicon technology to minimize power consumption.

Unlike NB-IoT which burns battery by not supporting graceful handover for mobile endpoints, the DMSS seamless handover is optimized for power consumption of mobile endpoints.


The DMSS Network can track location independent of GPS/GNSS. The result is not just lower cost and power by eliminating the need for a GPS/GNSS receiver, but more importantly the unique ability for site-level accuracy even with endpoints indoors.


One network, global coverage. No roaming agreements. No need for multiple bands. Predictable power budget. Low touch certification process.


The DMSS is purpose-built only for the LPWA endpoints it serves and will not be compromised based on the needs of higher value endpoints such as cellular handsets.

Handset driven network settings (such as PSM & eDRX timers) contribute to an unpredictable battery life for NB-IoT devices.

Rural areas rely on 2G/3G network infrastructure which will support handsets, but represent coverage gaps for NB-IoT devices.
