New version of Bluetooth 5.0 - works 4 times faster and 2 times further
The other day, Bluetooth Sig reported that their wireless data transfer format will be updated next year. Bluetooth 5.0 (or simply version 5) will work 4 times faster and transfer data 2 times further. I must say that this is the first serious update of the Blue tooth over the past six years.
Of course, these are not all the innovations that beat the Bluetooth developer. It is currently known that due to the function advertising Packet The packages of the transmitted information will also grow several times.
For the first time, Bluetooth technology was started in 1994, when a wireless data transfer was used to replace some cables. It was developed by the company Ericsson. The famous Swedish manufacturer of telecommunication equipment called the new data transfer standard at a distance in honor of the legendary Scandinavian king Harald I Sinezubogo.
Bluetooth logo consists of two runes "Hagalaz" And "Berkana". They symbolize growth, development and unification.
- With the help of Bluetooth, it became possible to quickly transfer files from the computer to peripheral devices. The first such devices were gaming jastics, headset, headphones, etc. Later, when such a system was introduced into mobile devices, it became possible to exchange files between phones and synchronize them for various actions. A few years ago, it was thanks to Bluetooth that it was possible to exchange ringtones, music and photos from mobile phones from each other
- Radio waves are used to transfer data on this technology ISM band with a frequency of 2.4-2.48 GHz. Since during the operation of Bluetooth the frequency restructuring occurs in a wave -like, several operating devices using this data transmission standard at a distance practically do not cause failures and interference when working each other
- Bluetooth 1.0 It was implemented four years after the first use of the “blue tooth”. She had several drawbacks, among which the most significant was the insufficient compatibility between devices from various developers
- Part of the problems were solved when developing a version Bluetooth 1.1. The main innovation, this format of the data of data is a signal power indexing. That a little solved the compatibility problem. But, the main breakthrough this kind was performed when developing a version 1.2
- In 2004, it was developed Bluetooth 2.0. Feature of this version increase in speed Enhanced Data Rate (Edr). Thanks to the introduction of this technology, it was possible to achieve speed - 2.1 Mbps. At the same time, the basic speed increased to 1.1. Mbit/second
- Three years later, in 2007, a version was released Bluetooth 2.1. With its help, a “blue tooth” can be requested by the characteristics of the device. In addition, the developer managed to reduce the energy consumption of the battery during operation
- IN Bluetooth 3.0 was implemented hS technology, which allowed to increase data transfer speed to 24 Mbit/second. At the same time, the algorithms of this technology could choose the speed of data transfer depending on the volume of files. This was done to save battery
- In June 2010, Bluetooth Sig approved the specification Bluetooth 4.0. To carry out high-speed data transfer, this version uses Wi-Fi. At the same time, for miniature devices and in order to save battery, data transmission protocols implemented in previous Bluetooth certificates were decided to leave
- The latest version of the Blue tooth at the moment was Bluetooth 4.2. It was released in December 2014. During its development, the main emphasis was on an increase in data transfer speed and to increase the confidentiality of information
- Today announced Bluetooth 5.0. According to Mark Powell, Executive Director of Bluetooth Sig, in the fifth version of this technology for data transfer, the radius of action is 2 times, and the speed is 4 times. Great possibilities of broadcast packages are also announced. What exactly will be improved yet. In the Bluetooth 2 version, such packages have the size of 47 bytes
- Wide -large packages are data sent not to a particular device, but to those who can accept them. Based on such packages, work "Lights"who, without installing the connection with other devices, transmit data on their location. With their help, you can replace the GPS system inside a certain area or building. For example, display information on the exhibiting exhibition, when approaching it
- Digital technologies industry experts believe that Bluetooth 5.0 may become the basis "Internet of things". Modules 4.2 used today have a limited range. In addition, in the fifth version of the “blue tooth”, the developers even better implemented the charge of charge. The modules of the future Bluetooth 5 standard can work even in devices that "eat" from the solar battery
- It is already known that the first IT companion to begin to produce devices supporting Bluetooth 5.0 Microsoft. Most likely these will be the elements of a “smart home” and wearable gadgets. Also, the new version of this technology was interested in advertising people employed in the field of sale of goods and services. The increased range of the Bluetooth 5.0 will allow you to use this standard to send advertising messages to gadgets that fell into the "field" of the translator
