What Is the Wireless Industry?

Wireless English: wireless. Generally speaking, "wireless" refers to radio or radio waves, the category of communication fields. For example: wireless network (such as "wireless bridge, wireless AP"), TV Broadcasting Co., Ltd. (also known as "wireless TV station")

wireless

English: wireless

Generally, "wireless" means

Full name is Wireless Fidelity.

The so-called wireless network includes both global voice and data networks that allow users to establish long-range wireless connections, as well as infrared and radio frequency technologies optimized for short-range wireless connections. They are very similar to the purpose of wired networks, and the biggest difference lies in the transmission medium. The difference is that using radio technology to replace the network cable can back up each other with the wired network.

In 2004, the IEEE's "i" research group developed a unified wireless security standard, some of which have been implemented by many wireless equipment and software vendors to alleviate known 802.11 security issues. Formerly known as the 802.11i standard, this standard is now widely known as WPA2, which stands for Wi-Fi Protected Access Version 2. WAP2 replaces WPA, which is a hybrid of the old, insecure WEP standard that is backward compatible with existing wireless infrastructure. WPA uses RC4 encryption, which is weaker than AES encryption used in WPA2. WAP2 is currently the best solution for wireless networks, and it is expected to continue to do so for the foreseeable future. Most WPA2-enabled wireless access points have a feature called Wi-Fi Protected Setup (WPS), which has a security flaw that allows an attacker to obtain a WPA2 password, allowing him or her to connect to the network without authorization. This feature should be turned off as much as possible to avoid attacks. ^[1]
