Nordic Semiconductor has set a new standard in the low-power cellular IoT and Wi-Fi-based asset tracking markets with its nRF9151 System-in-Package (SiP) module and nRF7000 Wi-Fi 6 companion IC.

Nordic announced on the 2nd that its low-power cellular and Wi-Fi solutions have been adopted by IoT solution company Sentinum's latest asset tracker, the Juno Cellular Tracker.

This product features cellular IoT and Wi-Fi-based hybrid positioning technology that provides precise information on asset location, handling history, and status, both indoors and outdoors.

The Juno cellular tracker features Nordic's nRF9151 System-in-Package (SiP) module and nRF7000 Wi-Fi 6 companion IC.

The nRF9151 is a low-power solution that integrates a cellular modem supporting both LTE-M and NB-IoT, a GNSS, and an application processor on a single chip, making it ideal for small, battery-powered IoT devices.

Here, stable device management and location data processing are possible by utilizing the Memfault-based nRF cloud.

The Juno tracker has a built-in 3-axis MEMS accelerometer to detect movement, tilt, opening, and tampering., supports activity-based tracking and event logging without the need for separate additional sensors.

The 'TH' model features high-precision temperature and humidity sensors, enabling real-time monitoring of asset status in various environments such as logistics, industry, and healthcare.

The method of location confirmation is also noteworthy.

In indoor or urban environments, SSID-based Wi-Fi scanning provides accuracy of a few meters, while outdoors, GNSS is selectively utilized to minimize power consumption.

In environments where Wi-Fi or satellite signals are difficult to obtain, the device automatically switches to cellular network-based location estimation, enabling uninterrupted tracking.

Sentinum claims to have maximized power efficiency to enable years of use without battery replacement, based on once-daily uplink and GNSS position acquisition.

This is thanks to the nRF9151's low-power architecture and integrated MCU/modem design.

Juno Tracker integrates with Sentinum's Orbix platform, making data visualization and integration with external systems easy.
