Bluetooth technology is stronger than "it" but "it" is much stronger than radio coverage

WI-FI is a technology that can connect terminals such as personal computers and handheld devices (such as tablet computers and mobile phones) to each other wirelessly. In fact, it is a high-frequency radio signal. Wireless fidelity is a brand of wireless network communications technology and is held by the WI-FI Alliance to improve interoperability between wireless network products based on the IEEE 802.11 standard. Some people call LANs that use the IEEE 802.11 series protocols "wireless fidelity," and even equate wireless fidelity with the wireless Internet (WI-FI is an important part of WLAN).

WI-FI is also a wireless communication protocol. Its official name is IEEE 802.11b. Like Bluetooth, WI-FI is also a short-range wireless communication technology. The WI-FI rate can reach up to llMbit/s. Although the data security is worse than that of the Bluetooth technology, it is slightly better in terms of the coverage of the radio waves. It can be up to 100m, not to mention home or office, or smaller. The entire building can also be used.

Wireless Internet access can be simply understood as wireless Internet access. Almost all smartphones, tablet computers, and notebook computers support wireless fidelity Internet access. It is the most widely used wireless network transmission technology today. Wireless Internet access is actually the conversion of wired network signals into wireless signals. Wireless routers are used to support related technologies such as computers, mobile phones, and tablet computers.

Although the wireless communication quality transmitted by wireless fidelity technology is not very good, the data security performance is worse than that of Bluetooth, and the transmission quality needs to be improved. However, the transmission speed is very fast and can reach 54 Mbit/s, which is in line with the needs of personal and social information. The main advantage of wireless fidelity is that it does not require cabling and can be unrestricted by cabling conditions. Therefore, it is ideally suited to the needs of mobile office users. Since the transmitted signal power is less than 100mW and is lower than the mobile phone's transmit power, wireless fidelity access to the Internet is relatively It is also relatively safe and healthy.
