Invented in the 1990s and successfully applied for the wireless network technology patent in the United States at 1996.
When IEEE formally defined the standard of 802. 1 1 in 1999, IEEE selected and determined that the wireless network technology invented by CSIRO was the best in the world, so the wireless network technology standard of CSIRO became the core technology standard of Wi-Fi in 20 10.

Combined architecture:
Generally speaking, the basic equipment for building a wireless network is the wireless network card and AP, so it can share the network resources with the existing wired architecture in a wireless way, and the construction cost and complexity are much lower than the traditional wired network.
AP is the abbreviation of access point, which is generally translated as "wireless access point" or "bridge". It mainly acts as a bridge between wireless workstation and wired LAN in MAC of media access control layer. With AP, wireless workstations can connect to the network quickly and conveniently, just like hubs in general wired networks.
If it's just a point-to-point network of several computers, you don't need an AP, just equip each computer with a wireless network card.
