Ultra-low power wireless connectivity specialist Nordic Semiconductor took its first step in the direct-to-device (D2D) sector with the launch of a development kit and modem software for non-terrestrial networks (NTN).

The nRF9151 SMA development kit uses semi-precision coaxial RF connectors in place of internal antennas, a configuration the company stated enables engineers to make direct connections with high-performance external aerials or laboratory equipment.

Nordic Semiconductor explained the arrangement can be used for cellular IoT and DECT NR+ in addition to NTN.

It expects typical uses to be in remote areas with weak mobile signals, smart buildings with dense node counts and industrial settings.

The D2D modem firmware adds NB-IoT NTN capabilities compatible with 3GPP Rel-17 standards, along with LTE-M and GNSS for hybrid set-ups.

Kristian Saether, senior product director for long-range, said the nRF9151 provides engineers and RF experts “the granular control needed to validate their most ambitious designs”, contributing to efforts to “push the boundaries of wireless” and satellite connectivity.

Nordic Semiconductor stated the development kit includes high-performance antennas from Taoglas and Kyocera; IoT SIMs; and trial data covering terrestrial and satellite connectivity from Deutsche Telekom, Onomondo and Monogoto.
