The advancement of information technology has pushed human society towards a more efficient and intelligent direction. Just like the creation of various mythological stories, the greatness of mankind is also due to its unparalleled creativity. Humans know what they want, and know exactly how to achieve it, from the agricultural civilization to the industrial civilization, and now the Internet era, science and technology has become the most fundamental productivity, but also make the world more exciting.
With Wifi, Zigbee, GSM and other wireless technologies in full swing today, Bluetooth is still the dominant wireless communication technology. From the very beginning of 1.0 to the current Bluetooth version 5, Bluetooth technology in the wireless market still maintains high growth. In particular, the universal development of mobile Internet has effectively expanded the application prospects of Bluetooth, and Bluetooth technology has become the standard for all kinds of mobile smart terminals. Why Bluetooth technology can become the mainstay of wireless technology? Bluetooth technology compared with other mainstream wireless technology advantages? In this paper, we talk about the application and development of Bluetooth technology in mobile Internet from the aspects of transmission speed, power consumption and security.
I.? The historical evolution of Bluetooth technology
Bluetooth transmission as a general-purpose communication technology, the most important function is to replace the transmission of data cables for portable devices and their applications, such as cell phones and cell phones, cell phones and other Bluetooth devices to connect and transmit. From version 1.0 to 5, Bluetooth has given more and more electronic devices an easy, safe and low-cost connection solution.
II.? The advantages of Bluetooth technology in mobile Internet applications through five generations of development, and break through the power consumption problems that hinder the widespread use of Bluetooth technology, transmission speed and power consumption can reach 150kbye, 40mA and 10kbye, 30uA respectively. which BLE technology maximizes the standby time, fast connection and low peak transmit/receive power consumption for the expansion of the Bluetooth market as well as mobile Internet convenience applications is significant. Of course, Wifi, Zigbee, private protocol, Bluetooth, GSM, CDMA, WCDMA, TD-SCDMA? are also the current mainstream wireless communication technologies, however, in the Internet applications, GSM, CDMA, WCDMA, TD-SCDMA? belongs to the standard of cell phone communication, so the following is mainly Bluetooth technology with Wifi, Zigbee and private protocol communication in mobile Internet applications to compare the advantages and disadvantages of Bluetooth technology. Bluetooth transmission as a universal communication technology, the most important function is to replace the transmission of data cables for portable devices and their applications, such as cell phone to cell phone, cell phone and other Bluetooth devices connection and transmission. Bluetooth empowers more and more electronic devices with easy, safe and low-cost connectivity solutions.
1.? Bluetooth and Wifi: Wifi is currently the most competitive wireless communication technology, many aspects and Bluetooth is very similar to the development of Bluetooth technology is the most threatening wireless technology. Compared with Bluetooth technology, Wifi communication distance and transmission rate are more advantageous, the disadvantage is high power consumption, high cost, radiation. The mobility of mobile Internet applications requires intelligent terminal equipment to have good endurance, so Wifi is not suitable for wearable and other low-power transmission devices, in the short term can not replace Bluetooth technology. In addition, the communication distance of Wifi is far, and the security of data transmission is easy to receive hacker attacks.
2.? Bluetooth and Zigbee: Zigbee is a technology proposal between wireless tagging technology and Bluetooth, with close range, low complexity, low cost, low power consumption, fast response time, its power consumption performance is better than Bluetooth, and security is between Wifi and Bluetooth. However, the working rate is low (20 ~ 250kbps), only to meet the needs of low-rate transmission data applications, belongs to the niche communication technology, the worst thing is that cell phones do not support, in the smartphone-based mobile Internet applications, Zigbee can be said to be basically uncompetitive.
3.? Bluetooth and private protocols: private protocols for wireless applications the most important advantage of the program is the cost is cheap, but the application surface is relatively narrow, generally used for mine safety, home and school communication and other specific applications. Comprehensive view, although Bluetooth technology and Wifi,?ZigBee, private protocols and other wireless transmission technology compared to the existence of certain shortcomings, but also faces a variety of wireless technology competition, but because of Bluetooth technology, communication speed, power consumption and security have reached the appropriate balance, so that the Bluetooth technology in the mobile Internet applications still have sufficient competitiveness.
III. Development and Prospects of Bluetooth Technology
Currently, the most important application of Bluetooth technology is in the field of consumer electronics, with the popularization of Bluetooth and the rise of the mobile Internet, so that the Bluetooth technology applications from cell phones, tablet PCs and other portable devices to the Internet of Things, health care, and other new areas of expansion, and many of the Bluetooth applications based on mobile platforms for the wireless market as a whole to bring new business opportunities.
Based on the launch of Bluetooth 5, also allows many indoor location service providers to harvest a surprise, before the search for interest in the electronic has said that the Bluetooth 5 this technological innovation for the indoor positioning industry injected a more powerful impetus, which is not only the positioning accuracy of the enhancement, but also so that the Bluetooth indoor positioning technology can be in a more complex environment, stable operation, for the realization of a richer range of application scenarios to provide the technical Support. Seek interest as a leading domestic indoor location solutions provider, has been for industry, medical, nursing homes, smart buildings, factories, exhibitions, museums / exhibition halls, kindergartens, prisons, fire and other areas to provide a number of safe and efficient operation, and now combined with the Bluetooth 5 technology, whether to achieve more intelligent scenes, let's wait and see!
