This document discusses communication methods for smart things and their requirements. It lists requirements like low energy, mobility, proximity detection, and security. Potential communication mediums are then presented, including Bluetooth, BLE, WiFi, Zigbee, LPWAN networks, mobile networks, NFC/RFID, ultrasound, and voice. Examples of smart devices and the communication methods they use are provided, such as Philips Hue lights using Zigbee, iBeacons using BLE, WiFi scales, smartwatches using BLE/WiFi/BT, and Alexa using WiFi. Bluetooth iAP is described as allowing only accessory and user connection through BLE, with iOS app connection, energy efficiency,
