External Antennas And ESP32 Long-Range Mode


Everybody talks about LoRa to bridge long distances. Today we will have a look into how we can extend the range of a normal ESP32. You will also learn how to do that and stay legal. And maybe we even can reduce the power consumption of the chip if we do not need the extended range. And what we learn, we can also be used for our ordinary Wi-Fi network.
In this and the next video, we will:
- Understand the basics of antennas for wireless transmission. If you are not interested in that, you find a link to the more hands-on part of the video in the description.
- Introduce the new Long-Range mode for the ESP32 invented by Espressif
- See how we can attach external antennas to ESP32 modules
- Find an easy way to compare Wi-Fi antennas
- Compare the performance of some typical antennas. Commercially available and home-made
- Reduce the TX power of the ESP32 to stay legal and check its effect on overall power consumption
