Hello, I have a few questions about the nRF9151 DECT NR+ modem. I see that from the docs that the max TX power is 19dBm, so it's a Class III device as defined in section 6.2.1 of TS 103 636-2. Is this a hardware limitation, or a a software one due to regulatory compliance or something? The docs mention that data rate is up 3.4Mbps. However, the closest value I found in TS 103 636-2 was Table A.4.2-3, which uses the operating bandwidth of 6.912MHz. The docs says the max operating bandwidth of the chip itself is 1.728MHz. Does that mean the docs talk about the capabilities of the DECT NR+ PHY and not the chip in terms of bitrate? Thank you.

Hello,

I have a few questions about the nRF9151 DECT NR+ modem.

I see that from the docs that the max TX power is 19dBm, so it's a Class III device as defined in section 6.2.1 of TS 103 636-2. Is this a hardware limitation, or a a software one due to regulatory compliance or something?
