u-blox extends reach of secure LTE-M, NB-IoT module with 400MHz support

Improves coverage within buildings for business and mission-critical applications

Thalwil, Switzerland – April 13, 2021 – u-blox (SIX:UBXN), a leading global provider of positioning and wireless communication technologies and services, has extended its industry leading SARA-R5 LTE-M and NB-IoT communications family with the introduction of a module that supports the 400-450 MHz LTE spectrum bands available in Europe, Asia, and Latin America.

The u-blox SARA-R540S can communicate on LTE bands 31, 72, 73, 87, and 88. These lower-frequency bands have good propagation characteristics, helping customers in the smart meter, public safety, smart grid, and smart cities markets meet strict indoor and outdoor coverage requirements that might otherwise be difficult to reach over standard cellular connectivity options.

The u-blox SARA-R540S is being introduced, in part, to service a growing trend to install dedicated communications infrastructure for IoT ecosystems ensuring high levels of availability and resilience. For example, the shift to smart energy grids will demand close coordination of distributed renewable power plants and millions of demand-management controllers installed at customer premises. Therefore, it needs a robust communications infrastructure to enable it.

The SARA-R540S is based on the u-blox UBX-R5 cellular chipset and takes advantage of many of the features already engineered into the u-blox SARA-R5 family. This vertical ownership of the module’s hardware and software means that u-blox can guarantee long-term device availability and provide lifetime support for the entire platform for decades to come – an important factor in many IoT deployments.

Other hardware features include a high RF power output to further enhance the reach of the SARA-R540S in places, such as within buildings, where ensuring coverage can be challenging. The module supports Power Class 3 transmission over standard LTE bands and Power Class 2, at an enhanced 26 dBm maximum output power, in the 450 MHz spectrum. The SARA-R540S also supports the 3GPP bands 87 and 88 in the 410 MHz spectrum, as well as dynamic antenna tuning to help designers achieve maximum efficiency and coverage.

The module has been tuned for energy efficiency, which is important for remote and battery-powered products, such as water meters and gas meters. The SARA-R540S draws less than 1 μA of current in power-saving mode and has a ‘last-gasp’ function to send a last message before it finally loses its power supply, for example, during a power outage or in case of a tampering event.

The SARA-R540S module also has the necessary hardware and software onboard to support u-blox’s IoT Security-as-a-Service strategy. This makes it ideal for devices that transmit critical and confidential information in, for example, industrial or infrastructure applications such as metering. The module has a built-in hardware root of trust, which provides the foundation for secure authentication of the device in the field. It also implements a lightweight pre-shared key management system designed specifically for low-power wide-area (LPWA) applications to guarantee state-of-the-art security.
