Bluetooth Technology Alliance announced in Wednesday the Bluetooth 4.2 standard: Faster data transfer, more privacy features, IPV6 network support. What are the specific changes and what are the areas that can play a role?

Bluetooth Technology Alliance's newly released Bluetooth 4.2 standard opens the door to the internet of things, especially for low-power smart devices.

The development of Bluetooth technology for many years is now very popular, not only become the standard of mobile devices such as smartphones and tablets, but also become the choice of most wireless headsets, wireless mice, handles and other devices. Compared with working in a similar band of WiFi wireless network technology, the advantages of Bluetooth is small, power-saving, very suitable for small size, running low power, communication distance is not long equipment. Before the Bluetooth standard version up to 4.1, and the more popular is 4.0.

with the further development of smart devices and the rise of the concept of Internet of things, the industry has put forward higher requirements for short-range wireless communication technology. In this context, Bluetooth 4.2 was born.

The biggest improvement of Bluetooth 4.2 is to support 6LowPAN, which is the low power wireless personal area network technology based on IPV6 protocol. This technology allows multiple Bluetooth devices to access the Internet or local area network via a single terminal. In the smart home system, the traditional home electrical equipment may be connected to the local area network for easy interaction and control, but most of the equipment is not suitable for high-bandwidth, high-power WiFi access mode. Smart sockets, smart switches, smart lamps, air conditioners, cleaning/humidification equipment, kitchen appliances, etc. are more suitable for use with Bluetooth transmission.

Previous standards for each device must be connected to the smartphone or PC to be controlled, which greatly limits the use of Bluetooth scenarios. Bluetooth 4.2 allows the same room to have only one or two Bluetooth to the local network access side (such as Bluetooth 4.2-enabled wireless APs), you can allow all the Bluetooth 4.2 devices in the room to access the home network without the need for mobile phone or PC participation. In this way, most of the smart home appliances can abandon the more complex WiFi connection, switch to light and small power consumption low Bluetooth transmission. On the other hand, since the WiFi network began to migrate to the 5GHZ band, the 2.4GHZ band of Bluetooth can avoid interference with WiFi. A large number of devices switched to Bluetooth will also reduce the router on the WiFi side of the parallel transmission pressure, improve the performance of the entire home LAN.
