IEEE 802.15.4 operating frequencies

[Hiihtaja]

Hi !

in https://infocenter.nordicsemi.com/pdf/nRF52840_PS_v1.7.pdf specified operation frequencies

"

The IEEE 802.15.4 standard defines 16 channels [11 - 26] of 5 MHz each in the 2450 MHz frequency band. The FREQUENCY register of the radio module must be programmed according to table below for correct operation on the center frequency defined for each channel.

"

What mean "must be" in this context ? I have own radio and expect to use any frequency with IEEE 802.15.4  radio.

Or this type of radio must use those frequency from list ? IEEE type of modulation might not work so well on other frequencies like 2402Mhz for example.

Hi Eugene,

IEEE 802.15.4 is not just about the radio frequency range, you need to operate on defined channels. Every channel has its own band.

Hi Charlie !

I understand whole standart definition, but I hope nRF chip itself dosn't have any problem if I would like utilize frequency 2402Mhz for test IEEE radio. So those steps are coming from standart definitions only, not from HW.
