Preliminary
1) If the end-product using the Module is designed to have an antenna port that is accessible to the
end-user then a unique antenna connector (as permissible by FCC) must be used (e.g. RP (Reverse
Polarity)-SMA socket).
2) If an RF coaxial cable is used between the module RF output and the enclosure, then a unique
antenna connector must be used in the enclosure wall for interface with antenna.
1.2 WLR089U0/WLR089UC Usage Instructions under Modular Approval
For USA/Canada, the module has been certified for the modulation modes listed below. The user
must ensure that the module will only work on the 902-928 MHz frequency band and with one of the
modulation modes listed below, when used in USA and Canada.
• Operating Channels:
• 500kHz BW:
• 903MHz ~ 927.5MHz
o 8 Uplink Channels, Channel Spacing 1.6MHz
o 8 Downlink Channels, Channel Spacing 0.6MHz
• 125kHz BW:
o 902.3MHz ~ 927.5MHz
▪ 64 Channels, Channel Spacing 200kHz
o 902.3MHz ~ 927.3 MHz
▪ 26 Channels, Channel Spacing 1MHz
• Modulation: LoRa®
• Spreading Factor:
• 500kHz BW: 7~12
• 125kHz BW: 7~10
The host product manufacturer must ensure that the RF behavior adheres to the certification (e.g.
FCC, ISED) requirements when the module is installed in the final host product.
The availability of some specific channels and/or operational frequency bands are country dependent
and should be programmed at the Host product factory to match the intended destination. Regulatory
bodies prohibit exposing the settings to the end user. This requirement needs to be taken care of via
Host implementation.
The Host product manufacturer must ensure that the RF behavior adheres to the certification (e.g. FCC,
ISED) requirements when the module is installed in the final Host product.
