TH 28.4.2022, 11-14:00 (3h) + FR 29.4.2022, 10-15:00 (4h)


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.

Wireless Technology

Radio waves!

Wi-Fi (2.4/2.5 GHz) - faster, 10xbluetooth distance, more energy

Bluetooth, BLE (Bluetooth Low Energy) (2.4/2.5 GHz) - slower, shorter distance, less energy (good when you need to make something very small)

Zigbee (Mesh Protocol) (2.4/2.5 GHz) - low-power, low data rate, and close proximity

Antenna Cellular (3G/4G/5G) - very high operational costs and power requirements

RFID vs. NFC - RFID can be scanned up to 100m, NFC is limited to small distances

Wireless ranges
