((( This workshop is only open to S&&O students ))) 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. More infos >>

Wireless Technologies

Wi-Fi - faster, 10xbluetooth distance, more energy Bluetooth, BLE (Bluetooth Low Energy) - slower, shorter distance, less energy (good when you need to make something very small) Zigbee (Mesh Protocol) - 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 How WiFi and Cell Phones Work | Wireless Communication Explained

Bluetooth vs WiFi - What's the difference?
