Bluetooth Technology and Wireless Local Area Network   type c tws earbuds

The IEEE802.11 standard is mainly used for wireless data storage access services of users and user terminals in office local area networks and campus networks, with a maximum rate of 2Mb/s. In order to meet people's requirements for transmission distance and transmission rate, the IEEE group has introduced IEEE802.11a and IEEE802.11b
two standards. The main technical difference between the three lies in the MAC sublayer and the physical layer. www.bjbjaudio.com  <a style="opacity:0.0;color:#ffffff">type c tws earbuds</a>

In form, Bluetooth is very similar to a wireless local area network (WLAN) using IEEE802.11, and they have in common:
(1) Work on the 2.4GHz frequency band;
(2) Support mobile networking, users can flexibly move the location of the computing device and maintain a continuous network connection;
(3) There is no need to use physical lines, and the installation is very simple;    <a style="opacity:0.0;color:#ffffff">type c tws earbuds</a>

(4) Because the high-frequency radio waves used by the wireless network can penetrate walls or glass windows, network equipment can be placed arbitrarily within the effective range;
(5) Multi-layer security protection measures can fully ensure user privacy:
(6) When changing the network structure or layout, it is not necessary to reset the network. www.bjbjaudio.com    <a style="opacity:0.0;color:#ffffff">type c tws earbuds</a>

But there is a difference between them. Mainly in the following points:
(1) First of all, the coverage of Bluetooth is small and the performance is relatively low. It is connected to other devices through the application of communication protocols: the transmission rate of the IEEE802.11b standard of the wireless local area network is up to 11Mb/s and the range is 50m, which can cover the entire floor and the entire office, it is connected through an underlying transport protocol.
(2) Secondly, compared with 80211, the Bluetooth communication module has low power consumption, low cost, and simple operation during communication. Another Bluetooth-equipped device located within a radius of 10m is searched for by the Bluetooth-equipped device, and the two parties can communicate after authentication. 1 Bluetooth-equipped device can communicate with 7 Bluetooth devices simultaneously. Unlike wireless LAN, the other party can be a variety of devices such as mobile phones and digital cameras. Bluetooth technology also provides a common interface for existing digital networks and peripherals to form a group of personal ad hoc connected devices away from fixed networks. www.bjbjaudio.com    <a style="opacity:0.0;color:#ffffff">type c tws earbuds</a>

Bluetooth devices use the ISM band for real-time data and voice transmission, which means that in the office, home and on the go, there is no need to lay special cables and connectors, and a Bluetooth remote control device can form a point-to-multipoint connection, that is, a "Micro-grid", any Bluetooth device in the network can communicate with the device without complicated software support. www.bjbjaudio.com          <a style="opacity:0.0;color:#ffffff">type c tws earbuds</a>

Bluetooth technology has a complete set of protocols that can be applied to more occasions. Bluetooth frequency hopping is faster, larger and more stable, while also featuring lower power consumption and more flexibility. However, 802.11 only specifies the physical layer and MAC layer of the Open System Interconnection Reference Model (OSI/RM), which provides more
The high transfer rate of WLAN only supports data communication. www.bjbjaudio.com          <a style="opacity:0.0;color:#ffffff">type c tws earbuds</a>
