ARF868 Radio Modems- Guide utilisateur / User guide version V2.2.3
2.3.3 Standard mode
The table below shows the main RF characteristics of ARF868 modems. We can separate 2 types of use:
• High powers up to 500mW
• Powers < or equal to 25mW.
2.3.3.1 Use at 500mW: maximum range
The table below enables users to configure their ARF868 modems to obtain the longest possible range at 500mW in the 869.4 to 869.6MHz
band.
