Bluetooth 4 will soon bring a lot of new individual sports and health care products
Bluetooth low energy technology formerly known as Nokia Wibree development technology, mobile wireless communication technology itself is a very low power designed specifically for mobile devices. Bluetooth technology alliance, after being accepted and standardized renamed Bluetooth Low Energy (Bluetooth low energy). The characteristics of the technology lies in the peak period, low average value and the standby energy consumption; wireless standard, low cost, and can ensure the equipment compatibility and interoperability; and the smaller mobile phone and PC related accessories, lower cost.
SIG chief marketing officer of Suke Jawanda
With the Bluetooth special interest group (SIG) announced officially adopted low power technology as the representative of the advantages of Bluetooth specification version 4, SIG certification program is open to all Bluetooth 4 specification product. SIG chief marketing officer Suke Jawanda says, Bluetooth version 4 is the introduction of the development of Bluetooth technology "has the history of milepost meaning" event, it will be the traditional Bluetooth, Bluetooth low energy and high technology of Bluetooth three specification and can be made one, according to its function to simultaneously or separately in different equipment.
According to the core specification SIG issued a white paper, Bluetooth 4 low power mode with double and single mode two application. Dual mode applications, Bluetooth low energy function is integrated in the classic Bluetooth controller existing, or in the current Bluetooth Technology (2.1EDR/3.0HS) to increase the low power stack chip, the overall architecture basically unchanged, so the cost increase is limited. Single mode applications for highly integrated, compact device, with lightweight link layer, standby mode operation, simple device to support the ultra low power recovery, reliable data transmission from point to point, secure encrypted connections; and the link layer is applied to the network connecting the sensor, and to ensure that the wireless transmission, can through Bluetooth low power transmission.
Suke Jawanda believes that, in the next few quarters, will see a lot of a Bluetooth 4 sports and fitness equipment (such as a watch, a heart rate monitor, pedometer), hygiene and health care equipment (weight, blood pressure, blood glucose meter), consumer electronics products (remote control 3D glasses, advanced, intelligent home furnishing (equipment) thermostat, security system), various types of equipment available. Coupled with the personal computer, mobile phone, tablet computer has been able to connect with the sensor, which can be safely from the heart rate monitor, blood glucose, blood pressure gauge, thermometer and other equipment to collect information and transformed into data, allowing users to use.
For example, there are about 200000000 8 ten million patients with diabetes today all over the world, as long as through the blood glucose meter with Bluetooth technology, they can put their blood glucose readings to a mobile phone, tablet computer or personal computer storage system, and through the process in the equipment for data analysis, and then the data into charts thus, record and analyze their weekly, monthly and yearly blood glucose readings. This will be the existing medical users, manufacturers of medical equipment and application developers opened new experiences and huge business opportunities. In June this year, SIG announced version 4 of Bluetooth health thermometer and a heart rate monitor configuration file, the next few months, such as multiple files blood pressure profiles, short-range sensing configuration file will be issued.
The company currently in progress in Bluetooth 4.
MediaTek (MediaTek) practice is the latest wireless connection four in one single chip MT6620. Allegedly, MT6620 supports standard advanced wireless connection rich, including 2.4/5 GHz, Wi-Fi Direct and dual frequency 802.11n Wi-Fi Wi-Fi HotSpot, Bluetooth, GPS/Galilei/SBAS/QZSS and 4.0+HS dual-mode operation has been patented AlwaysLocate technology, and FM radio transceiver. Technology certification, MT6620 Wi-Fi has passed 802.11n certification, including WPS2.0 and WAPI; and the Bluetooth controller and BlueAngle host software have been certified by 4.0+HS.
TI China wireless terminal business marketing and technical manager Bing Jie
TI (TI) Chinese wireless terminal business marketing and technical manager Bing Jie said, Bluetooth 4 release will greatly expand its applications, games, sports equipment, automatic control, medical monitoring, white goods, and even the Internet of things will become the potential target market. Taking TI CC2567 as an example, its not only support between ultra low power ANT+ devices are directly used for short distance communication, mobile devices but also support PC, smart phones and tablet computer and so on Bluetooth technology. As the industry's first dual mode devices, circuit board area required for CC2567 than the two single mode solution (a ANT+, a Bluetooth) design 80% less, and by having a built-in compatibility of shared antenna to realize synchronous work, compared with single mode to solve the ANT+ scheme, the wireless transmission cover range can be extended 1 times. In addition, the CC2564/WL1271/1281 also supports the BT4.0 specification, and passed the SIG certification.
As an important game player in the market, Qualcomm Atheros interviewed here said, market data about Bluetooth low energy shows that, the main market of this technology will be the health / medicine, intelligent home furnishing automation and personal use of the environment, such as the PC safety and interaction with intelligent mobile phone and PC. Of course, these applications on the hardware requirements include very low power consumption, low power Bluetooth to realize this point; another is "gateway" equipment and powerful software solutions, such as notebook computer, tablet computer and smart mobile phone.
