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. | 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.

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
7-layer OSI model
Open Systems Interconnection Model https://www.imperva.com/learn/wp-content/uploads/sites/13/2020/02/OSI-7-layers.jpg.webp
