Note :
in South Korea, the channels defined for the “923” version must be shifted by 100KHz
to meet Korean regulations i.e. 917.1MHz to 923.3MHz with 200KHz steps.
1.5.4.7
Output Power
The conducted output power can be adjusted from 0dBm to +30dBm.
This offers a wide range of adjustment to cover all specific countries EIRP requirements.
Antenna gain has to be considered to adjust the conducted output power to not overrule the
max allowed EIRP.

Conducted output power range
0dBm to +30dBm
Ripple in the band
+/- 2dB
Variation over temperature range (-20°C to +55°C)
+/- 2dB
For Wirnet iBTS FDx, depending on the number of simultaneous Tx, the power of each
carrier must be adjusted to not overrule the max +30dBm total power.
The Wirnet iBTS FDx is able to transmit 4 RF signals simultaneously at each RF antenna port.
1.5.4.8
Out of band emissions
Due to the very low noise transmitter, the LoRa LOC module is able to achieve excellent out
of band emissions levels in the LTE, UMTS and GSM uplink or downlink bands.
The performances are summarized in the following table:
