Latest IoT Wireless Technology Development
•22
• Bluetooth v4.2 (making Bluetooth Smart Devices truly IoT)
- IPv6 support: devices become true Internet end points
- Higher throughput due to longer payload
- More secure and more power efficient
• Wi-Fi Aware (Wi-Fi alliance’s answer to IoT)
- Uses the same Wi-Fi physical layer
- Provides continuous device-to-device discovery
- Allows bidirectional sharing of small pieces of information, e.g. location
data, sensor readings
• ZigBee 3.0 (unifying various ZigBee environments)
- To be finalized by the end of 2015
- Pulls various applications and profiles under the same umbrella
- No longer needs a bridge device between different sets of ZigBee
devices
