Analysis of the new generation of Bluetooth 5.0 wireless transmission technology

1. Analysis of Bluetooth 5.0

As a new generation of wireless transmission technology, compared with the previous Bluetooth 4.2LE technology, the most significant change of Bluetooth 5.0 is that the transmission speed has been greatly improved. The upper limit of the new version of Bluetooth transmission speed is 24Mbps, far exceeding the previous Bluetooth transmission speed. It is twice as much as the previous 4.2LE version. Of course, it is unlikely that you will reach this extreme speed in real life, but you can still experience a significant speed increase. Bluetooth 5.0 technology doubles the speed. Calculated according to the existing indicators, it is expected to reach a transmission distance of 300 meters and a speed limit of 24Mbps. This speed undoubtedly makes the function expansion of Bluetooth 5.0 even more powerful, bringing more applications to Bluetooth devices.

1.2 Has a lower power consumption level

As we all know, Bluetooth is an essential function of smart portable terminal products. As more and more applications such as smart phone devices and mobile payment need to turn on Bluetooth to enjoy convenient functions and gradually integrate into people's lives, the power consumption of Bluetooth has become a smart A big killer of mobile phone standby time. For this reason, Bluetooth 5.0 greatly reduces the power consumption of Bluetooth, so that people no longer have to worry about the short standby time when using Bluetooth.

As the main connection method for smart wearable devices and smart homes, Bluetooth 5.0 brings lower power consumption and more stable performance, which will effectively solve the battery life problem of smart devices in the future and display more abundant functional applications.

1.3 brings a longer effective distance

Another important improvement of Bluetooth 5.0 is that its effective distance is 4 times that of the previous version. Therefore, when you stand 300 meters away from the Bluetooth speaker with your mobile phone, it will continue to play your favorite songs. That is to say, in theory, the effective working distance between Bluetooth transmitting and receiving devices can reach 300 meters. Of course, the actual effective distance also depends on the electronic equipment you use.

1.4 New navigation beacon function

In addition, the significance of Bluetooth 5.0 is not only faster and farther, it will also bring improvements to the development of location services. Bluetooth 5.0 technology adds more navigation functions to this, so this technology can be used as an indoor navigation beacon or similar positioning device, and combined with Wi-Fi can achieve indoor positioning with an accuracy of less than 1 meter. For example, if you get lost in a busy downtown building, you can use Bluetooth technology to find your destination even in a sprawling commercial center.

1.5 Expand the functions of the Internet of Things

At present, the Internet of Things is still hot, bringing a lot of vision to our smart home. Therefore, Bluetooth 5.0 technology has carried out many low-level optimizations especially for the application of the Internet of Things, and strives to provide services for smart homes with lower power consumption and higher performance. The previous Bluetooth v4.2 already had some IoT-focused features, and Bluetooth 5.0 puts these features at the center. Of course, its longer range will definitely improve smart home integration, and the stronger transmission capacity means that the new standard will allow IoT devices to communicate more easily. The new Bluetooth 5.0 will redefine the way Bluetooth devices transmit information, allowing them to transform from the mode of application-matching devices to the realm of connectionless transmission of the Internet of Things. Bring more convenience.

1.6 brings a more convenient connection method

The new Bluetooth 5.0 can add more data transmission functions, and hardware manufacturers can create more complex connection systems through Bluetooth 5.0, such as Beacon or location services. Therefore, the advertising data sent by the Bluetooth device can send a small amount of information to the target device, even without pairing. This means that Bluetooth 5.0 technology will completely change the current connection method and simplify the pairing process of devices. Also, some previous Bluetooth version updates only required a software upgrade, but Bluetooth 5.0 will likely require an upgrade to a new chip. However, old hardware is still compatible with Bluetooth 5.0, but it cannot enjoy the new performance.

2. Bluetooth 5.0 brings new changes

Technically, the new Bluetooth 5.0 standard has a comprehensive improvement over the Bluetooth 4.2 standard, and both communication speed, communication distance and communication capacity have been greatly improved. At present, the competition for communication standards of the Internet of Things is becoming increasingly fierce, and Bluetooth Low Energy (BLE) technology has become one of the leading communication standards in the field of Internet of Things. However, compared with other standards, Bluetooth does not have an absolute advantage. However, the launch of Bluetooth 5.0 this time can bring some new features through low-power Bluetooth BLE, which will undoubtedly make up a lot of technical capital for this standard battle in time. With the help of these new features, Bluetooth 5.0 is expected to assist low-power consumption. Consuming Bluetooth BLE, making it the ultimate wireless communication standard for the Internet of Things.

Especially when the communication speed of the new Bluetooth 5.0 is doubled, which means that its power consumption is also halved, and lower power consumption brings many benefits, especially in many Internet of Things applications, the communication speed The requirements are not high, because most IoT applications do not need to transmit streaming media, and wearable products are a typical representative of such applications. Take a sports bracelet as an example. Health data mainly includes information such as pulse rate, steps, and exercise methods. However, battery life is a key factor for the success of a bracelet. If the communication speed is doubled, the real communication time can be reduced to half at most, so this is equivalent to reducing the power consumption to nearly half of the original. Half the power consumption means double the battery life, which is a great benefit for wearable products. As we all know, Bluetooth is already the most widely used technical standard in the wearable field. Bluetooth technology has achieved great success in the consumer Internet of Things due to its low power consumption and fast transmission speed, but engineers still have many choices when looking at the entire Internet of Things market. The ever-evolving market dominates the world. So now many products have to support multiple connection standards to adapt to more application environments.

Bluetooth 5.0 doubles the communication speed and doubles the speed of BLE. For most current BLE applications, the Bluetooth 4.2 standard is sufficient, so the increase in speed will not immediately improve the user experience. However, from another perspective, power consumption has become one of the most troublesome issues for current wearable products. In addition, the increased speed will allow software or firmware updates to take less time. Although software update is not a common function, since the amount of data that needs to be downloaded during software update is large, the increase in communication speed can also effectively reduce the power consumption during software update. The four times the communication distance of Bluetooth 5.0 means that Bluetooth will snatch Wi-Fi's share in the smart home market. In addition, Bluetooth 5.0 further increases the communication distance, which is great news for other applications of BLE, because whether it is a Bluetooth mouse or a wearable, users no longer have to worry about being dropped due to the distance. , which is especially important for Bluetooth headsets.

3. Peek into the development prospects of the new Bluetooth 5.0 standard

The establishment of the new Bluetooth 5.0 standard will undoubtedly bring great changes to users and manufacturers.

First of all, for consumers, the establishment of the new Bluetooth 5.0 standard will undoubtedly bring greater convenience. As we all know, the current Bluetooth 4.2 standard is not enough to maintain the connection of all Bluetooth devices in a family. When the number of devices increases, a series of common wireless network problems such as connection drop, incompatibility, and slow transmission speed will be exposed. You must know that if everything is as advertised, the new 5.0 standard will completely change this situation. Thanks to the changes in the new Bluetooth 5.0 technology, the upgraded Bluetooth signal will show a stronger ability to resist WiFi and LTE signal interference, and can avoid congested radio waves within a certain range, so that various digital devices in the family can maintain smooth signals. Users who pursue minimalism upgrade all related peripherals to the Bluetooth version. At that time, our faster and more convenient Bluetooth connection is no longer a dream, and it is no longer out of reach.

In fact, in practical applications, for some high-demand Bluetooth connections, such as Bluetooth smart watches, the current standard has reached its limit, and we are clearly aware that it is time to upgrade. Because most of the current smart watches rely on the Bluetooth connection with the mobile phone, the connection method of Bluetooth 4.2 wireless technology has obviously restricted the function expansion of smart watches, and has become an important technical bottleneck restricting the continued development of smart watches. The official establishment of the new Bluetooth 5.0 standard will undoubtedly benefit a lot for major smart watch manufacturers. It can bring more and richer smart watch function applications from the higher-speed wireless connection of Bluetooth 5.0, and support Bluetooth 5.0. Connection will also become a major selling point of the new generation of smart watches, which will be favored and sought after by users. To put it further, in fact, the establishment of the new Bluetooth 5.0 standard has opened the door to our smart home application "Internet of Things". For the Internet of Things, the birth of Bluetooth 5.0 is indeed at the right time. Some statistical agencies predict that by 2021, there will be 48 billion Internet-connected devices in the world, about one-third of which will be equipped with Bluetooth. It can be expected that the wireless connection market around the world will grow even faster at that time. By 2021, the annual shipment of IC equipment is expected to reach 10 billion units. The release of Bluetooth 5.0 is expected to create new opportunities in various vertical fields of the Internet of Things, because it can significantly reduce the complexity and cost of the system, and give equipment suppliers more room for flexibility, that is, through the new features and new technologies of Bluetooth 5.0 Develop various emerging application methods and scenarios to enrich our IoT smart life.

Finally, it is worth noting that the various functional advantages brought by the current Bluetooth 5.0 technology require "two-way" compatibility to be realized. In other words, in addition to your smartphone supporting Bluetooth 5.0, the connected Bluetooth device also needs to support 5.0 standard to achieve the best results. As far as the current development stage is concerned, although there are not many hardware devices supporting the Bluetooth 5.0 standard, with the continuous extension and development of smart homes, Bluetooth 5.0 devices will definitely become a future trend. In particular, the advancement and evolution of the Internet of Things technology will inevitably promote the accelerated popularization of Bluetooth 5.0, and Bluetooth 5.0 will also bring innovative functional applications to the Internet of Things. The two complement each other and bring out the best in each other.
