Features of bluetooth technology tws earbuds airpods

Bluetooth technology was created to replace the cables used by mobile devices with radio waves. It tries to complete the functions of ordinary cables with the same cost and safety, so that mobile users can get rid of the constraints of cables, which determines that Bluetooth technology has the following technical characteristics. www.bjbjaudio.com   <a style="opacity:0.0;color:#ffffff">tws earbuds airpods</a>

1. Low cost
In order to replace ordinary cables, it must have a price similar to that of ordinary cables, so that it can be accepted by ordinary consumers and make this technology popular. The ultimate goal of Bluetooth is to be integrated in a CMOS chip priced at $5. At present, the price of bluetooth chips has dropped
If it does not come down, there are both economic and technological factors. From a technical point of view, the Bluetooth chip integrates wireless, baseband and link management functions, and the link management function can actually be implemented by hardware or software. If the link management function is implemented by software, then the chip Be simplified and the price will be reasonable. www.bjbjaudio.com       <a style="opacity:0.0;color:#ffffff">tws earbuds airpods</a>          <a style="opacity:0.0;color:#ffffff">tws earbuds airpods</a>

2. Low power consumption and small size
The original purpose of Bluetooth technology is to interconnect small mobile devices and their peripherals. Its market targets are mobile notebook computers, mobile phones, small PDAs and their peripherals. Therefore, Bluetooth chips must have low power consumption and small size. features for easy integration into small portable devices. The output power of Bluetooth products is very small (only 1mW), only one millionth of the power used by microwave ovens, and a small part of mobile phones. www.bjbjaudio.com            <a style="opacity:0.0;color:#ffffff">tws earbuds airpods</a>

3 Near Field Communication
The communication distance of Bluetooth technology is 10m. If necessary, an amplifier can be selected to extend it to 100m. This is enough to place peripherals anywhere in the office without worrying about cable lengths. www.bjbjaudio.com    <a style="opacity:0.0;color:#ffffff">tws earbuds airpods</a>              <a style="opacity:0.0;color:#ffffff">tws earbuds airpods</a>

4. Security
Like other wireless signals, Bluetooth signals are easily intercepted, so the Bluetooth protocol provides authentication and encryption to ensure link-level security. The Bluetooth system authentication and encryption services are provided by the physical layer, using stream cipher encryption technology, which is suitable for hardware implementation, and the key is managed by high-level software. If the user has a higher level of confidentiality requirements, more advanced and more effective transport layer and application layer security mechanisms can be used. Authentication can effectively prevent spoofing and unwanted access, while encryption protects link privacy. In addition, the secrecy of frequency hopping technology and the limited transmission range of Bluetooth also make eavesdropping difficult. www.bjbjaudio.com            <a style="opacity:0.0;color:#ffffff">tws earbuds airpods</a>                    <a style="opacity:0.0;color:#ffffff">tws earbuds airpods</a>

However, while providing link-level authentication and encryption, it also hinders user-friendly access to some public application models, such as service discovery and virtual exchange of commercial cards. Therefore, in order to meet these different security requirements, the Bluetooth protocol defines three security modes. Mode 1 does not provide security, Mode 2 provides service-level security, and Mode 3 provides link-level security. www.bjbjaudio.com            <a style="opacity:0.0;color:#ffffff">tws earbuds airpods</a>           <a style="opacity:0.0;color:#ffffff">tws earbuds airpods</a>
