Not quite Line of Sight Test (869 Mhz LoRa)

What started off as a Line of Sight (LoS) range test for our LoRa transmitters, soon became not quite LoS as we ran out of room.

So we decided to keep on going…

Through bushes – LoRa signal getting through without a problem. ๐Ÿ™‚

Under the A13 – still working ๐Ÿ™‚

Top of Marsh Way bridge, approximate distance to receiver 600m (not LoS) – still working ๐Ÿ™‚

Bottom of Marsh Way bridge, approximate distance to receiver 750m (not quite LoS) – still working ๐Ÿ™‚

We kept on going until we reached Walden Avenue, now over 1km away from the receiver – and our LoRa transmitter still works! ๐Ÿ™‚

The LoRa transmitter’s RF signal was getting through this built up residential area plus a hill to get back to the receiver at our office. Going further down this road is when we started experiencing signal loss.

Wow, that is some amazing performance from a battery powered transmitter on 869 Mhz.
