10 Radio parameters

The default radio parameters are determined by the values of

RADIO_DefaultRfProfile

RADIO_DefaultRfChannel

and

RADIO_DefaultRfTXPower

in the user settings. These non-

volatile parameters can be modiﬁed using

CMD_SET_REQ

. To modify their volatile counterparts

the commands

CMD_SET_PAPOWER_REQ

and

CMD_SET_CHANNEL_REQ

can be used.

The parameters must be chosen with prudence not only to ensure optimal

functionality, but also in compliance to the appropriate regulatory requirements

such as the FCC in the United States of America.

The module is pre-certiﬁed by mounting it on its EV-board. However, conformance of the

end-device to this certiﬁcation depends on the radiated power. Among other factors, the

radiated power depends on the selected antenna, the wiring to the antenna and the quality

of the power supply. Thus, it is highly recommended that the end-device manufacturer verify

the radiated power on the end application. The frequency channels of the module can be

selected from a 500 kHz grid.

10.1 Channel assignment

A means that the channel is allowed corresponding to the appropriate operational frequency

band requirements.

- means, that the channel is not allowed and is blocked by the ﬁrmware.

* means, that the channel in general is allowed, we recommend to use every second channel

as the 6dB bandwidth is 500 kHz to fulﬁll FCC $ 15.247 (a)(2).
