Subject: nRF9151 – EU coverage of mfw 2.0.2 and antenna gain (Schréder Sense One)
Dear Nordic
I'm working on CE and RCM certification for Schréder's SENSE ONE smart-city sensor, which uses the nRF9151 SiP for LTE-M / NB-IoT and GPS. DECT NR+ is not used. have a few questions before we brief our test lab.
1. Modem firmware coverage in the EU
The DEKRA EU-type examination certificate 82630RNB.001 lists hardware nRF9151 LACA A1 with modem firmware mfw_nrf91x1_0.4.0. The JAS-ANZ certificate CBA251159.01 and the Telstra approval cover mfw_nrf91x1_2.0.2. We plan to ship 2.0.2. Can you confirm that 2.0.2 is covered by your EU technical file and Declaration of Conformity? If it is, could you send any supporting update or addendum?
2. Updated EU Declaration of Conformity
Your EU DoC dated 11 March 2026 cites EN 301 489-52 V1.2.1, while the DEKRA certificate cites V1.3.1. Since older versions lose presumption of conformity from 15 November 2026, is an updated DoC citing V1.3.1 available?
3. Antenna gain
Our LTE antenna is the TE Linx ANT-LTE-SP610-T. Its peak gain is 5.1 dBi at 700–960 MHz and 5.3 dBi at 1710–2200 MHz on the reference ground plane. Neither the DEKRA nor the JAS-ANZ certificate states a maximum antenna gain. Can you confirm that this antenna is within the conditions of the EU and Australian module approvals, and tell us any gain limits we should design to?
4. Integration guide
We found a nRF9160 Hardware Integration Guide v1.1. Could you send the nRF9151 equivalent, including any guidance on host-level RED testing (radiated spurious emissions and receiver blocking) and GPS antenna integration? Our GPS antenna is the Taoglas GGBLA.125.A.
Thanks for your help.
Kind regards,
Fergus Dixon
