Compared with the previous Bluetooth technology, Bluetooth 5 has the advantages of four times the transmission range, twice the transmission speed, and eight times the amount of broadcast message load, and also solves the interference problem with other wireless technologies. Helps coexist with other communications technologies in the Internet of Things (IoT) market.
However, according to Chen Junzhi, sales manager at Nordic, most of the devices currently connected are still based on mobile phones. However, the features of Bluetooth 5 mentioned above are not necessary for mobile phones; like Bluetooth 5 can support long-distance transmission, but the same Wi-Fi and LTE can also be used as long-distance transmission technologies. In the absence of obvious application requirements, the mobile phone maker does not necessarily choose Bluetooth 5. Bluetooth 4.2 can also meet the needs of consumers for short-distance transmission. Therefore, the mobile phone industry has not yet A large number of imports is one of the main reasons why Bluetooth 5 has not been rapidly popularized.
So, what is the current business model of Bluetooth 5? Chen Junzhi pointed out that most applications of Bluetooth 5 nowadays are used to connect equipment and equipment (point-to-point), such as for data transmission between electronic fences. When two electronic fences are used When the distance between the settings is long and you need to communicate with each other to transfer data, you can use Bluetooth 5 as the transmission method.
However, such applications still cannot rapidly promote the popularity of Bluetooth 5. Therefore, Chen Junzhi believes that the introduction of mobile phone manufacturers is still the key to the popularity of Bluetooth 5. Because most consumers or applications are still accustomed to using mobile phones. , And then connect to other terminal equipment; So, if Bluetooth 5 is to be popularized in the future, it may have to wait for the application demand to increase, prompting the mobile phone industry to use Bluetooth 5 before the penetration rate will gradually increase. High-speed transmission may be an opportunity because Samsung Galaxy S8/Galaxy Note 8 and Apple's iPhone 8/iPhone X are all used as the starting point for the introduction of Bluetooth 5 to meet consumer demand for high-speed transmission.
