5 GHz Wi-Fi DX record @ 745 km

Post by Konrad »

On August 12, 2020 I set my new Wi-Fi DX record during a very strong tropospheric ducting propagation. I logged a 5 GHz Wi-Fi network from Northern Denmark at Dylewska Mountain (Dylewska Góra), Poland at a distance of 745 km. Unfortunately my stationary mast with antenna for Wi-Fi DXing has been damaged three months ago, so the DX-pedition was the only option.

I believe this is also a world distance record of Wi-Fi signal reception.

I can't get my 5 GHz network in my shack without the use of a signal booster.

This 745 km record is not an indoor Wi-Fi network. Internet service providers use outdoor equipment installed on tall buildings, masts or chimneys. Look at some Mikrotik or Ubiquiti wireless devices.

As long as there is no obstruction to the horizon, the signal can propagate very well via tropo on GHz bands. I have seen much stronger signal levels via tropospheric ducting than in accordance to the free space loss calculations. It can act like a waveguide.

Out of over 20000 networks which I have logged at my QTH via tropospheric propgation, only ~30 of them were (presumably) indoor devices. This is something like 0.1%. I believe that my current record of an indoor 5 GHz network catch is 210 km, see the Indoor consumer Wi-Fi routers section: https://fmdx.pl/the-best-of-wi-fi-dx/

During last summer I built new 20m mast with a 105 cm dual-polarization dish antenna. Using this setup in September 2020 I received a network from Ukraine at a distance of 481 km. It is really super effective: https://fmdx.pl/ubiquiti-rocketdish-5g34/

There are also daily logs, just switch between them in the menu on the left.
There's not much going on during wintertime on GHz bands though.
