Today we have three partially overlapping wireless technology for data transfer - Wi-Fi, Bluetooth and ZigBee. Each of them, which is typical, is constantly trying to get into someone else's territory. So, constantly improving the specification of each of the above technologies reduce the consumption of transceivers and expand coverage. In practice this leads to the fact that we have more than one stop solution, and a combination capable of operating in several ranges directly supporting all possible standards.
An example of the above can serve as information on plans for the development of a standard Bluetooth. Specification Update Bluetooth, which is expected in November 2013, and in 2014 and 2015, will focus on the low-power modes and multiple connections. In fact, it is almost a complete invasion of Bluetooth under the responsibility of ZigBee standard, which was created for sensors and sensors with wireless connectivity.
In the future, Bluetooth LE will focus on a wider range of sensors : to monitor the health of the human body, as well as for industrial, automotive, and other needs. To connect to the Internet billions of sensors and devices standard Bluetooth LE will support the protocol IPv6. Data rate increase from the current 1 Mbit / s to 2 Mbit / s parity consumption or even the possibility to reduce consumption. This will provide an increase in the coverage area.
Among other improvements will accelerate the reconnection, which will save battery power, increase the level of data protection from interception, aid in the orientation in areas multicast data (broadcast) .
