USB WiFi stick antenna 2.4ghz


43.33 Km LOS with USB WiFi stick

Is it possible?
Hard to say, so before attending the real location some calculation with the help of the software is essential. Curiosity was the main reason, and if there is just a marginal possibility it's worth to give a try. All experiments and measurements are done randomly without notices to any parties to scan the real situation on the field.


As you can find out from the software calculation, radio link between two identical WiFi stations is possible with the standard equipment. In this case standard means cheap, easy available WiFi equipment with following characteristics:

TX power : 0,02 W
RX sensitivity : 5uV (-93 dBm)
Antenna gain : 15dBi
Line loss : 1dB
