About the radio frequency parameters and distance of WL33.

[WWang.15]

Dear ST experts.

We are a module manufacturer. We have designed a module based on WL33. We have been using ST's dk board for verification. However, when we tested the distance, the original dk board was about 200 meters. With a 20dbm and -12X sensitivity, we have high expectations for this chip. Do you have ST distance test reports and parameters?
2. If our deviation is <2.5Khz, does it mean that we need to replace the TCXO?

Hello

In order to understand better the cause of this behaviour I need to have more details on the RF parameters  used (TX power, data rate, frequency deviation and channel filter).

Consider that the max power our kit can deliver is 16 dBm. To reach 20 dBm is necessary a BOM change.

Are you using one kit as transmitter and a second kit as receiver.
