WiFi network architecture
Generally, the basic equipment for setting up a wireless network is a wireless network card and an AP, so that network resources can be shared in a wireless mode with the existing wired architecture, and the cost and complexity of the installation are much lower than that of the traditional wired network.
If it’s just a peer-to-peer network of several computers, you don’t need an AP, just each computer is equipped with a wireless network card. AP is the abbreviation of Access Point, which is generally translated as a wireless access point. It mainly acts as a bridge between wireless workstations and wired local area networks in the media access control layer MAC.
With AP, just like the Hub of a general wired network, wireless workstations can be connected to the network quickly and easily. Especially for the use of broadband, wireless fidelity has more advantages.
After the wired broadband network (ADSL, residential LAN, etc.) arrives at the home, connect to an AP, and then install a wireless network card in the computer. It is enough for an ordinary family to have one AP, even after the user’s neighborhood is authorized, there is no need to increase the port, and the Internet can be shared.
How WiFi works
The 802.11 standard that WiFi follows is the radio communication technology used by the military in the past, and it is still an important communication technology for the US military’s communication equipment to counter electronic interference.
Because the SS (Spread Spectrum) technology used in WiFi has very good anti-interference capabilities, and when anti-tracking and anti-eavesdropping are required, it has excellent effects at the same time, there is no need to worry that WiFi technology cannot provide a stable network service.
Simply summarize the communication principle in one sentence, using a 2.4G frequency band to realize point-to-point wireless communication between the base station and the terminal, and the link layer adopts the Ethernet protocol as the core to realize the addressing and verification of information transmission.
It can realize multi-device wireless networking with a communication distance ranging from tens of meters to two or three hundred meters.
WiFi is a supplement to the existing communication system and can be regarded as a supplement to 3G.
The wireless access technology mainly includes IEEE 802.11, 802.15, 802.16, and 802.20 standards, which refer to WLAN, wireless personal area network WPAN;
Bluetooth and USB, Wireless metropolitan area network WMAN;
WIMAX and broadband mobile access WBMA, etc.
Generally speaking, WPAN provides ultra-short range wireless high data transmission rate connection; WMAN provides metropolitan area coverage and high data transmission rate; WBMA provides wide coverage, high mobility, and high data transmission rate; WiFi can provide hotspot coverage and low mobility Performance and high data transfer rate.
Now technologies such as OFDM, MIMO (Multiple Input Multiple Output), smart antennas, and software radio have begun to be applied to wireless LANs to improve WiFi performance.
For example, 802.11n plans to combine MIMO and OFDM to double the data rate. In addition, improvements in antennas and transmission technologies have greatly increased the transmission distance of wireless local area networks, which can reach several kilometers.
