What does a private wireless LAN address mean?

The private wireless LAN address refers to a unique private network address that iPhone uses on each wireless LAN it joins, called media access. Control (MAC) address. If a network cannot use a private address (for example, to provide parental controls or identify an iPhone as authorized to join), you can stop using a private address for the network.

Wireless LAN

Before the invention of wireless LAN WLAN, people wanted to communicate and communicate through the network For communication, we must first use physical cables-copper strands to form an electronic operation path. In order to improve efficiency and speed, optical fiber was later invented. When the network developed to a certain scale, people discovered that it was very difficult to set up, disassemble, and re-layout and reconstruct this wired network on the original basis, and the cost and price were also very high. Therefore, the WLAN networking method It came into being.

WLAN started in 1997. In June of that year, the first wireless LAN standard IEEE802.11 was officially promulgated and implemented, providing a unified standard for wireless LAN technology, but the transmission rate at that time was only 1~2 Mbit/s. Subsequently, the IEEE committee began to formulate new WLAN standards, named IEEE802.11a and IEEE802.11b respectively. The IEEE802.llb standard was first officially promulgated in September 1999, with a rate of 11 Mbit/s. The improved IEEE802.11a standard was officially promulgated at the end of 2001. Its transmission rate can reach 54 Mbit/s, which is almost 5 times that of the IEEE802.llb standard. Despite this, the application of WLAN has not really started because the entire WLAN application environment is not mature.

Wireless LAN (English: Wireless LAN, abbreviated as WLAN) is a local area network that does not use any wires or transmission cables to connect. It uses radio waves as the medium for data transmission, and the transmission distance is generally only a few dozen meters. The backbone network of a wireless LAN usually uses wired cables, and wireless LAN users access the wireless LAN through one or more wireless adapters. Wireless LAN is now widely used in business districts, universities, airports, and other public areas.

The most common standard for wireless LAN is the 802.11 series of standards defined by IEEE.
