Bluetooth 4.0 specification is accepted. We are waiting for new achievements

High-speed data transfer protocols are now "baked" like hotcakes. Wireless modules of standard 3.0 did not have time to settle in various devices, as the Bluetooth Special Interest Group (SIG) adopted the Bluetooth Core Specification Version 4.0 . Interestingly, in the fourth quarter of this year, manufacturers promise to release mobile and not so devices with integrated Bluetooth 4.0 module. Detailed specifications Bluetooth Core Specification Version 4.0. let's put a lot of bucks under the cut.

So, devices with a new communication module will be able to exchange data at speeds up to 24 Mbps. Agree, this is much more than the most common now (at least in the CIS countries) Bluetooth 2.1 + EDR with its 3 Mbit / s.

The feature of Bluetooth 4.0 is not only high data transfer speed, which should be enough for most modern devices, but also low power consumption of the communication module. The fact is that the developers have applied a new energy-saving technology that allows you to embed Bluetooth 4.0, even in low-power devices with low power.

Such devices can be used in almost all areas, including medicine, entertainment, sports and others.

Note that in Bluetooth 4.0. increased data transfer security - now everything that is transmitted is encrypted using the AES-128 protocol. Another advantage is a significant expansion of the range of the communication module - up to one hundred and more meters.

The developers claim that the standard “tablet”, a 3-volt battery type CR 2025, Bluetooth 4.0 communication module can work for several years . It would be interesting to check this statement in practice, right? I am glad that the wait is quite a bit.

The press release also reported that all members of the Bluetooth SIG working group will be able to “touch” devices with Bluetooth 4.0 at the next, 37th SIG meeting, which should take place this time in Barcelona, ​​Spain, from 4 to 8 October. Developers will provide devices for testing with both previous Bluetooth specifications and Bluetooth 4.0.

Immediately after this, manufacturers will be able to actively implement new types of communication modules in their own devices.

In general, let's summarize. The main advantages of Bluetooth 4.0 are:

- low energy consumption;
- high data transfer rate, up to 24 Mbps;
- increased range, over 100 meters;

Well, Bluetooth 4.0, we are waiting for you.

Here is the official press release specification.
