#ESPrtk- ESP32 RTK Long Range - 500m , 1km , 2km - distance testing radio WIFI 2.4Ghz .

More information : https://esprtk.com/blog-esprtk-wifi-long-range/
Today we have a test on the communication distance between 2 ESP32 modules running ESPrtk firmware.
The focus of this test is the distance ( long range), not the accuracy of the RTK receiver.
(The video has 2 parts: Prepare the hardware and check the distance outdoors.
Skip to 5:00 start the journey right away.)
The communication distance between the two ESPrtk modules was amazing, we started with 500m, 800m then 1km, 1.6km and even 2km. At these distances ESPrtk can receive signals if there is a line of sight from Rover to Base.
At a distance of 1.6km, the received signal strength level is 5 (the highest is 9 for 1m distance).
The packets received on both Base and Rover are 100% accurate, they are encrypted with AES256 before being sent with 3 CRC integrity checks (1 in PHY layer, 1 in MAC layer and 1 in frame layer of ESPrtk). Only ESPrtk Rover devices can decode ESPrtk Base's packages, this is to ensure the data is transmitted correctly and reliably on the receiver side.

We believe that ESPrtk can communicate at a distance of 3km, unfortunately our test area does not have a good line of sight to go further.
Maybe we will come back with another video to check at a distance of 3km .
If you intend to test your ESPrtk and make videos about it, try to go beyond our 2km distance.
