2.3.3.2 Usage up to 25mW: maximum number of channels
The rest of the 863-870MHz band is segmented into sub-bands of 25mW, each with their regulatory requirements. The ARF868 modem makes
the best use of all the possibilities of this band to enable a maximum number of applications. The characteristics are given in the table below:

(see chapter § 5.3)
Modification through COMMAND ATS200
(see chapter §5.3)
Power up to 14dBm (500mW)
For each frequency is assigned a channel
number «C» with the formula :
Frequency = 863.0125 + ((C-13)*0.0125)
with C= 13 to 571.
C values available depend on the data rate.
