From mobile phones to wearable devices, from smart homes to the Internet of Things, we have witnessed the renewal of technology expansion, and witnessed a new round of industry competition and shuffling market driven by technology and innovation. Ups and downs. In the new year, Bluetooth 4.2 will bring more imagination to our lives!
Technology upgrade Bluetooth 4.2 takes you to fly
Bluetooth wireless technology is a universal wireless standard that provides easy and secure connectivity to more and more devices and is one of the main technologies in the connected world. The Bluetooth core system includes a radio frequency transceiver, a baseband, and a protocol stack. The system provides services that enable connectivity and multiple data exchanges between different devices. Products can choose different configurations among the many functions of the core specifications, so that the products have different characteristics. Bluetooth 4.2 is an important update to the Bluetooth core specification, bringing exciting new features and benefits to Bluetooth Smart. This will bring more significant advantages to developers and vendors while providing a better user experience for consumers. Bluetooth 4.2 makes BluetoothSmart smarter and faster, making it the ideal wireless technology for the Internet of Things (IoT).
The Bluetooth 4.2 core specification includes the following main advantages:
1. Implement the Internet of Things: Support flexible Internet connection options (IPv6/6LoWPAN or Bluetooth Smart Gateway)
The biggest improvement of the new standard is also to support 6LoWPAN, Bluetooth 4.2 devices can access the Internet directly through IPv6 and 6LoWPAN. This technology allows multiple Bluetooth devices to access the Internet or a local area network through a terminal. In this way, most smart homes can abandon relatively complex WiFi connections and switch to Bluetooth transmission, making the connection between personal sensors and homes more convenient and faster.
2. Make Bluetooth Smart smarter: industry-leading privacy, energy efficiency and industry-standard security
Under this standard, if there is no user's permission, the Bluetooth signal will not be able to connect and track the user equipment, which greatly protects the user's privacy. You can use it safely on your wearable device without worrying about being tracked.
3. Make Bluetooth Smart faster: throughput speed and packet capacity increase.
The Bluetooth 4.2 standard increases data transfer speed by 2.5 times, mainly due to the fact that the capacity of Bluetooth Smart packets is 10 times higher than before, while reducing the transmission error rate, because the larger data transfer volume is improving the performance. At the same time, the battery loss is also reduced. Simply put, the device can work more easily and the battery standby time will be longer. For a brief introduction to Blutooth and Blutooth Smart, Bluetooth Smart is actually Bluetooth 4.0, and the Bluetooth Technology Alliance has diluted the X.0 concept, emphasizing Bluetooth Smart, because "X.0 is for Geek, Bluetooth" The SIG hopes that ordinary consumers can understand."
Smart home field Bluetooth and wifi
Smart home has quietly entered our lives. Mobile terminals such as mobile phones and tablets have become the remote controllers in their hands, and they are able to control the smart home at home at any time, and the wireless technology is connected to all of them. Among all the wireless communication technologies, Bluetooth and WiFi are the most well-known in the world, and they are also considered to be a pair of friends.
Bluetooth is more convenient, less energy-intensive, and more accessible than WiFi. In the smart home field, devices that use Bluetooth technology can achieve "conversation" between devices and devices without a network. This solves the problem. If there is no WiFi in the network, the smart home devices will continue to work.
In fact, WiFi and Bluetooth can be said to be complementary. At present, wireless transmission technology has grown rapidly, among which Bluetooth is the fastest growing wireless transmission technology.

What is the potential of the Bluetooth 4.2 market?
In recent years, the Bluetooth market has experienced explosive growth. According to ABI statistics, the annual shipment of Bluetooth in 2014 is 3 billion, and will increase to 5 billion by 2018. According to the latest report from market research organization IHS Technology, the smart home market will show a compound annual growth rate of 56% in the next three years, and the product shipments in the market will reach 190 million units by 2018, while Bluetooth Smart will become nearly 3 years. The fastest growing wireless connectivity technology in the smart home sector. The data from Strategy AnalyTIcs also shows that there will be 224 million households, or 12% of the world's households, that will install at least one type of smart home system.
The Bluetooth Technology Alliance expects that more than 96% of mobile phones will be powered by Bluetooth Smart technology by 2018. At the same time, the Bluetooth Technology Alliance also expects Bluetooth Smart technology applications to further drive a variety of applications such as IoT and smart wear. It is expected that there will be a clear growth trend in smart home applications from 2013 to 2018. The Bluetooth 4.2 standard has been launched for more than a month, and the Bluetooth technology alliance was also revealed on the 20th of this month. The 4.2 specification chip will be officially mass-produced in the second half of this year. It is expected that Bluetooth 4.2 will be widely promoted and used in 2015, and the terminal products adopting the Bluetooth 4.2 standard will be rolled out in the second half of the year.
Industry voice
Version 4.2 brings new Bluetooth applications
The recently released version 4.2 extends Bluetooth applications from personal sensors to smart homes to the possibilities of the Internet of Things. At the recent Bluetooth Technology Alliance conference, applications such as wearables and smart homes are even more refreshing. XTOMP Smart Guitar Effects, designed by Hangzhou Start Line Technology, creates new sound effects with a growing library of over 300 algorithms and can be downloaded and updated via Bluetooth. XTOMP's free iOS/Android user software was developed in conjunction with EUMLAB, the world's leading mobile music application software team, which communicates with devices via Bluetooth.
Bluetooth 4.2 is an important element of the smart home low-power ecosystem
Smart homes that use Bluetooth may become a low-power ecosystem. When the smart phone controls the smart home, the iPhone has installed an application that can control the Bluetooth-enabled home device, and the new device does not need to install a new application, so that the new device can be put into use immediately. This is an advantage of Bluetooth. The popularity of Bluetooth 4.2 has also enhanced the security of Bluetooth, which means that smart homes with strong security can also be realized.
