Hello everyone
I’m testing 2 different frequency bands (433 MHz and 868 MHz) in LoRa in order to compare if one could be better than other in indoors environments, in theory 433 MHz has more penetration depth as it is a shorter wavelength.
At the moment I only have some heltec boards ESP32 LoRa v1 for the 433 MHz band, as I want the test to be as fair as possible I compare in a P2P connection with some heltec boards v2 in the 868 MHz band. All 4 nodes with omni antennas, all about 2 dBm gain (each pair of antenna specific for the corresponding band)
Now here comes the problem, I use the official libraries example code for Arduino (the LoRaReceiver and LoRaSender) and established a P2P connection for each band, always with SF12 and the sender at different tx power values. Everything works as expected for the v1 board, as soon as I increase the the tx power the RSSI improved. But for the v2 board with a tx power of 17 dBm start to lose packets and with 20 dBm only got a few (2 or 3).
The separation between nodes was a couple of rooms away, the signal for 433 and 868 was quite good no less than -103 or -102 (and only a few packets) no losses in 433 and the same in 868 at 14 dBm, so I think that there is something strange in the v2 board when increase the tx power, for 20 dBm apparently not working at all, even with the nodes side by side. In a nutshell is it possible that there is something in the heltec ESP32 LoRa v2 board that affects the reception at 17 or 20 dBm that not happen with the v1 board?
At this point I only get a fair comparative in both bands at 14 dBm of tx, I attach the test results for both bands.
Thanks in advance.
