S2C PRO DigiMesh RSPMA - same distance/noise and RSSI different

0 votes
Hello,

Here is the situation :

- All nodes [XB1] [XB2] [XB3] are S2C PRO DigiMesh with RSPMA + 2.4 Ghz antenna
- [XB1] and [XB2] are both 4 meters away from [XB3] (line of sight, no obstacles)
- [XB1] is right next to [XB2] (10 cm meter)
- all antennas are well screwed + all nodes have the same TW Power Level (PL)

Here is the problem :

- RSSI between [XB1] and [XB3] are not the same (-12dBm less) than RSSI between [XB2] and [XB3].

- I was expected to get "same" RSSI for both links

Beacuse both are exactly at the same distance from [XB3], and both share same noise/environment !

Does anyone have an explaination about this (strange) behavior ?

Many thanks,

Best regards,
