Transmission Power Levels¶
Channel 15 is not available as a transmitting device in FCC- or IC-regulated areas. You can use an RF220 Series to monitor radio traffic on channel 15 if the traffic is generated by devices other than an RF220 Series, but the RF220 Series will be unable to participate in message forwarding or mesh routing.
Channel 14 has a reduced maximum transmission power at txPwr >= 6.
Transmission power levels (in dB) in the RF220 Series modules are based on the txPwr setting and the channel. The following levels (±3dB) were read from a typical RF220 Series using a Rhode & Schwarz NRP-Z11 Power Sensor:
