Nordic Semiconductor, a global leader in low-power wireless technology, is expanding its influence in the indoor location services market based on its latest SoC, the nRF54L15.

With Chinese IoT specialist Minew adopting this chip in its new Bluetooth location relay beacon MBM04, Nordic's next-generation wireless platform is being credited with driving the advancement of indoor positioning technology across various industries.

Nordic has long built an IoT ecosystem centered on ultra-low power wireless technology, and the nRF54 series is a representative product family that combines high performance, low power, and multi-protocol support.

This application of the Minu MBM04 once again demonstrated that the nRF54L15 meets key requirements for complex indoor environments, such as high-volume data processing, long battery life, and support for high-density RF environments.

The nRF54L15 supports various protocols including Mesh, Thread, Matter, and Zigbee, centered on Bluetooth LE, and provides stable communication quality even in large indoor spaces through a maximum transmit output of +8dBm and an ultra-low power design.

In particular, deep sleep power consumption of 0.7μA is considered a factor that drastically reduces maintenance costs for battery-based beacon equipment.

In addition, the high-performance processing structure demonstrates significant strengths in relay beacon environments where tens to hundreds of surrounding tag data must be processed in real time.

This is also the decisive reason why it met the 'mass data processing capability and long-term scalability' required by Minu.

Minu's MBM04 is based on the nRF54L15 and can be selectively configured to play three roles: anchor, relay, and beacon.

Anchor mode provides a reference point for the indoor location system and performs tag scanning and data relay. Relay mode extends coverage by transmitting surrounding tag data to the network. Beacon mode enhances detection performance by emitting its own signal.

This structure reduces unnecessary infrastructure expansion while achieving positional accuracy of 3 to 5 meters indoors and precision of 1 to 3 meters in optimal environments.

Maintaining stable performance even in high-density RF environments is a direct reflection of the strengths of the Nordic wireless architecture.

During the development of the MBM04, Minu established high-performance processing, ultra-low power consumption, support for next-generation Bluetooth technology, and long-term scalability as key criteria. The nRF54L15 met all these conditions, and its structure, which can support high-precision distance measurement technologies such as future Bluetooth channel sounding, was particularly highly evaluated.

Fick Liu, Strategic Development Partner at Minu, said, “Nordic’s wireless technology has a clear competitive edge in terms of stability, energy efficiency, and the development ecosystem,” adding that “it also aligns well with our long-term product strategy.”

Nordic and Minu have maintained a long-standing cooperative relationship, and the MBM04 has established itself as a prime example of the technological synergy between the two companies. The nRF54L15-based MBM04 is expected to be utilized in various industrial sectors, including smart logistics, medical facilities, and smart buildings, and Nordic is projected to further expand its influence in the indoor location services market through this.
