Hello Victor,

Thanks for the reply. I have checked your example frequency band.

The 2360-2390 range is for Medical Device Radiocommunications (MedRadio) Band (MBAN) Services. The hospitals do not have to obtain a license to operate an MBAN. The usage of MBANs device is permitted by FCC under a “license by rule” system of registration and frequency coordination. It means an individual license is not required to operate a MedRadio device but to obey by the FCC’s technical rules. Only authorized service provides is allowed to use this band.

You can check FCC’s website -Medical Device Radiocommunications Service (MedRadio) | Federal Communications Commission (fcc.gov)

Bluetooth LE, ANT and 802.15.4 (thread and zigbee) operates in the 2.4 GHz ISM band at 2400-2483.5 MHz. So, I can say any of our communication protocols do not operate this band (2360-2390).

Do i need some special license to transmit at for example 2380MHz?

the ISM band is from 2400 to 2500MHz and in that band I can transmit up to 10mW/100mW without license.
of course you do not control frequency allocation but since you added 2360->2400MHz to your product you must have anticipated some sort of usage ot that band.

Hello Victor,

It depends on what customers intend to do since radio spectrum allocation is not controlled by us. If the plan is to use Bluetooth or Advance Network technology (ANT) or some other IEEE standard then all Nordic’s nRF52 and nRF53 devices operate in this range.

"And in which regions are transmissions allowed in this range?" - could you please a bit elaborate in this part of query?
