The New Bluetooth Standard Launched -- Bluetooth 5

The New Bluetooth Standard Launched -- Bluetooth 5

The new Bluetooth standard launched on June 17, 2016, and its standard number is not version 4.3 like as version 4.2, but called Bluetooth 5, rather than Bluetooth 5.0! According to past practice from version 2.0 to 3.0 to 4.0, the new standard the first digital changes are significant, Bluetooth 5, this name is indeed a lot simpler.

The New Bluetooth Standard Launched -- Bluetooth 5



In fact, Bluetooth development is a regular, the core is around the "faster, farther, and more power saving" to update its standard. According to the current information, all updates are the evolution of BLE technology, the classic Bluetooth BR and EDR wasn’t changed, the new standard Bluetooth 5 will be released in the second half of 2016 to early 2017.

Currently, Bluetooth SIG referred to Bluetooth 5 has the following important information:

(1) Bluetooth 5 standard‘s transmission distance is four times transmission distance than current one. Conventional Bluetooth technology use about 10 meters away, 4 times is 40 meters or so, you can cover most of the houses and individual stores, wireless technology, it can do more things that the greater scope of coverage, it is estimated if to be expanded to larger range, a BLE small base station will be required.

(2) Bluetooth 5 standard’s transfer rate will be 2 times than the current one, its transfer rate is faster. According to the current BLE rate is about 1M, 2 times is 2M. The higher the rate, the faster the connection is, the more things you can do, and the more powerful the functionality.

(3) Bluetooth 5 standard’s broadcast channel capacity expansion of 8 times, this is a little convoluted. In accordance with the current BLE work, there are three fixed frequency is used to broadcast, broadcast channel is fixed, the role is to broadcast some of the information to the public space equipment applications, so that other devices can search for what is this thing, whether to Connect it like that. Broadcast channel capacity of 8 times larger, it means that more things can be broadcast, do not connect to search out more and more clear information, called connection-free broadcast.

(4) Bluetooth 5 standard’s more powerful Internet of Things. Farther and higher rate, means that more and more things can be accessed the network through Bluetooth, house or store, warehouse can be connected as a whole network, to create smart home store warehouse.

(5) Bluetooth 5 standard’s indoor navigation and positioning functions. Now, more and more human activities are in large indoor space, such as subways, railway stations, airports, shopping malls, warehouses, factories. Indoor GPS cannot be used and so on, so Bluetooth 5 want to send point information through beacon (ordinary Bluetooth is a point to point connection, beacon can point to multipoint broadcast information that can be connected or not be connected), then there is a benefit, Is an urgent need to find a toilet faster and more accurate, for example.

The new Bluetooth standard come out, and now the version of Bluetooth is still under the application of the number of standards, 2.0, 2.1, 3.0, 4.0, 4.1, 4.2, 5. The official standard is called Bluetooth 5, not called Bluetooth 5.0.


For more information, please read to bite the standard specification but it has about 2000 pages, we just give you a brief only above. 

It will open up a road for equipment manufacturers to get significant improvements in smartphones, wearable smart devices and intelligent home appliances and other applications.
