Bluetooth Alliance 2015 focuses on smart home market

The Bluetooth Technology Alliance recently announced that Smart home has become the fastest growing area of Bluetooth. In recent years, Bluetooth in the Intelligent home field of the composite growth rate of more than 232%. The Bluetooth Technology Alliance also ranked smart home market as the main direction of the 2015.

ABI Research data show that 2014 Bluetooth shipments reached 3 billion, is expected in 2018, Bluetooth shipments will be more than 4.9 billion, more than 96% of mobile phones will become compatible with a variety of Bluetooth devices.

In the field of intelligent home, Bluetooth technology is also facing the competition from technology such as WiFi and ZigBee. However, Bluetooth Technology Alliance CMO Chovente previously on the "pretend to be a geek" (Micro-letter: geeker_ding), Bluetooth, WiFi, the two technologies are complementary to each other. WiFi has a larger power consumption and is suitable for mass data transmission. WiFi is a good choice if the device can use an external power supply. Low power Bluetooth technology is a good choice for devices that use batteries and when data transfer requirements are low. It is understood that after using the Low-power bluetooth ble technology, many smart devices use only one button battery to support their continuous work for 1-2 years.

In the field of IoT, the real opponent of Bluetooth should be the wireless technology of ZigBee, etc. using 802.15.4 protocol. Recently, Millet's green Rice introduced the family smart suit to use the ZigBee technology. According to "Pretend to be geek" understand, compared with the previous Bluetooth technology, ZigBee safety factor is high, easier to network, the realization of multiple intelligent devices interoperability. The ZigBee 3.0 standard, released at the end of last year, has increased interoperability among smart devices.

Bluetooth Technology Alliance is trying to change the original Bluetooth networking difficulties and other disadvantages. The latest Bluetooth 4.2 standard has been improved in terms of security and networking. It is said that Bluetooth 4.2 adds IPV6 support, and smart devices that use the new Bluetooth module can be directly connected to the Internet. While reducing power consumption, the 4.2 version of Bluetooth provides a government-level information security guarantee. The new privacy rights feature allows control weights back to consumers, and hackers have trouble tracking devices online via Bluetooth.

Due to the technical specifications of the limitations, Bluetooth in smart home applications are also facing the signal easily blocked by the wall and other issues. The Bluetooth Technology Alliance has set up an intelligent mesh research team, said Corrid, senior director of the Bluetooth Technology Alliance brand and developer Market, who pretends to be geeks. Since last October, several companies have made Bluetooth connections and networking through mesh technology. After the network of Bluetooth devices, the problem of weak Bluetooth signal will be improved obviously. It is understood that mesh technology by the Bluetooth chip manufacturers CSR launched in early 2014. With this technology, the Bluetooth network within the home can connect more than 65,000 devices. CSR officials have said that the introduction of mesh technology is used to intercept ZigBee. This technology has now been donated by CSR to the Bluetooth Technology Alliance, the Bluetooth Technology Alliance and associated companies to create a standard version of mesh technology for worldwide promotion. Qualcomm has invested 2.5 billion of dollars in October 2014 to buy a CSR firm to bolster its leadership position in the IoT chip sector.
