How WiFi and Cell Phones Work | Wireless Communication Explained
https://www.youtube.com/watch?v=kxLcwIMYmr0


This 2-day workshop aims to give an overview of a selection of wireless communication technologies good for sending sensor data between small devices and computers, and provides concrete examples for a subset of the selection. For example how to send data from an Arduino with WiFi or Bluetooth capability to a computer or how to send data between two such Arduinos or also between computers. We will work with protocols such as TCP, OSC, MIDI and MQTT.
