From the era of functional computers to the current era of smartphones, various powerful new technologies have emerged endlessly. Although some old technologies have become less important due to their emergence, this is not the case for Bluetooth technology. In a sense, Bluetooth is the technology that truly opens up wireless connectivity for mobile devices. However, due to the impact of new technologies such as Wi Fi, the importance of Bluetooth has become less and less important. However, the rise of intelligent wearable devices has made Bluetooth a feature that has regained its importance. Today, Tianbi will talk to you about Bluetooth in recent years.
Firstly, the author intends to talk about the evolution of Bluetooth from a conventional technical version perspective. When the Bluetooth technology standard was established and released in 1999, its technical version was V1.1, which was led by industry leaders such as Ericsson, IBM, Nokia, Toshiba, and Intel. V1.2 is a slightly improved version of the previous generation, which can be seen from the naming of the versions. The transmission speed of these two versions of Bluetooth technology is about 748-810kb/s, But V1.2 has added anti-interference frequency hopping function, which is more outstanding in terms of stability. Unfortunately, due to limited usage and excessive power consumption, these two generations of Bluetooth did not have widespread adoption.
With the evolution of technology, Bluetooth developed to V2.0 version in 2004. This version of Bluetooth technology has significantly improved transmission speed, reaching a transmission rate of 1.8Mbps to 3Mbps. However, it is distressing that the power consumption performance of Bluetooth at this stage is still not satisfactory. However, the accompanying Bluetooth V2.1 version has to some extent reduced power consumption and simplified the pairing process, It also improves a certain level of security. At this moment, Bluetooth has emerged in large numbers on mobile digital devices, and people are gradually realizing the convenience Bluetooth brings us.
Through naming, we can see that although the Bluetooth V2.1 version has made significant improvements, it is still a minor upgrade and has not undergone any qualitative changes. With the official release of the Bluetooth V3.0 specification, Bluetooth has officially entered the high-speed era. Under the Bluetooth V3.0 version, the data transfer rate has reached around 24Mbps (requiring both devices to be Bluetooth V3.0 or above), which is a qualitative change achieved through the 802.11 WIFI protocol. It is worth mentioning that although the Bluetooth V3.0 version has increased its speed by as much as 8 times, it effectively controls power consumption and operating mode due to Bluetooth's ability to control power consumption and operating mode when there is no large data exchange。
