Set of questions regarding nrf52840

We would like to ask for help with filling CoMaL (ang. minimial Content of Manual and Label), as there are many questions regarding our radio.

We are using nrf528400 only 1M mode and we are both scannig and advertising in non-adaptive mode. We have one Patch PCB antenna 2440AT62A0085: 2.4GHz Mini Patch Antenna, Circular Polarization.

  • Type of wide band modulation f.e. FHSS modulation, DSSS, OFDM;
    • ?
  • If FHSS modulation – numer of hopping frequencies and the dwell time per channel. For adaptive FHSS equipment – the average dwell time, maximum numer of hopping frequencies, minimum numer of hopping frequencies;
  • If it is adaptive equipment with adaptive mode or non-adaptive equipment or both,
    • non adaptive
  • If adaptive equipment – whether LBT based DAA or non-LBT based DAA is used, and the maximum Channel Occupancy Time implemented by the equipment; for LBT based adaptive equipment using wide band modulations other than FHSS, whether the equipment is Frame Based Equipment  or Load Based Equipment;
  • for non-adaptive equipment, the maximum duty cycle used by the equipment. For equipment with a dynamic behaviour with regard to RF Output Power and Duty Cycle, such behaviour shall be described. (e.g. the different combinations of duty cycle and corresponding power levels shall be declared);
  • the different transmit operating modes in which the equipment can operate;
  • the number of transmit chains;
  • if more than one transmit chain is active, whether the power is distributed equally or not
  • the number of receive chains;
  • whether or not antenna beamforming is implemented, and if so the maximum beamforming gain (Y) or the total antenna gain (G + Y) for this transmit operating mode;
    • only G max 3.5dB
  • the operating frequency range(s) of the equipment;
    • 2402 – 2480MHz
  • the Nominal Channel Bandwidth(s). For non-adaptive Frequency Hopping equipment, this is the nominal channel bandwidth when operating on a single hopping frequency;
  • the intended combination(s) of the radio equipment power settings and one or more antenna assemblies, their corresponding maximum gain(s) (G) and the resulting e.i.r.p. levels taking also into account the beamforming gain (Y) if applicable For equipment where in receive mode, the antenna assembly gain and/or beamforming gain is different from the transmit mode, the antenna assemblies, their corresponding maximum gain(s) (G) and the beamforming gain (Y) that apply in the receive mode;
  • the equipment type (e.g. Bluetooth, IEEE 802.11[i.3], IEEE 802.15.4 [i.4], proprietary, etc.);
  • whether or not the equipment supports a geo-location capability.
