The history of Wi-Fi
- The name Wi-Fi comes from
The term Wi-Fi is commonly mistaken for Wireless Fidelity, and even the Wi-Fi Alliance itself often uses the term “Wireless Fidelity” in press releases and documents, and Wi-Fi appears in an ITAA paper.
- Wi-Fi technology principle
Wireless network in the category of wireless LAN refers to “wireless compatibility certification”, which is essentially a commercial certification, but also a wireless networking technology, previously connected to computers through network cables, while Wi-Fi is connected to the network through radio waves.
Common is a wireless router, then the effective range of radio coverage of this wireless router can be connected to the Internet by Wi-Fi connection, if the wireless router is connected to an ADSL line or other Internet lines, it is also called a hotspot.
- Wi-Fi main functions
Wireless network Internet can be simply understood as wireless Internet access, almost all smart phones, tablets and laptops support Wi-Fi Internet access, is the most widely used wireless network transmission technology today.Wi-Fi 8 Wikipedia
In fact, it converts wired network signals into wireless signals, as introduced at the beginning, using wireless routers for related computers, mobile phones, tablets, etc. that support its technology.
If the mobile phone has a Wi-Fi function, when there is a Wi-Fi wireless signal, it can surf the Internet without going through the mobile Unicom network, saving the data fee.
Wireless network wireless Internet is more commonly used in large cities, although the wireless communication quality transmitted by Wi-Fi technology is not very good, the data security performance is worse than Bluetooth, and the transmission quality also needs to be improved, but the transmission speed is very fast, can reach 54Mbps, in line with the needs of personal and social informatization.
In July 2003, IEEE developed the third-generation Wi-Fi standard: 802.11g.
Smart WiFi 6 sub-female router
802.11g inherits the 2.4GHz band of 802.11b and the maximum 54Mbps transmission rate of 802.11a.
At the same time, it also uses CCK technology backward compatible with 802.11b products. From this point on, the IEEE will take backward compatibility into account when formulating each new generation of protocols.
802.11b/a/g/n/ac modes correspond to the rate
1. Second-generation WiFi: 802.11b, the highest speed is 11Mbps.
2. Third-generation WiFi: 802.11a/g, the highest rate is 54Mbps.
3. Fourth-generation WiFi: 802.11n, HT40 single stream maximum speed 150Mbps, HT40 4×4 MIMO maximum speed 600Mbps.
4. Generation 5 WiFi: 802.11ac (80M) single stream maximum rate 433.3Mbps; 8×8 MIMO (160M) maximum speed 6.928Gbps.
When did the wifi come out?
In 1991. Wi-Fi is a wireless network technology defined by IEEE, invented by CSIRO in the 90s and successfully patented in the United States in 1996.
Wi-Fi (Wireless Fidelity), also known as “mobile hotspot”, is a wireless LAN technology created in the IEEE 802.11 standard, based on the close relationship between the two systems, some people regard Wi-Fi as a synonym of the IEEE 802.11 standard.

Wi-Fi is owned by the Wi-Fi Alliance (founded in 1999 and officially renamed the Wi-Fi Alliance in October 2002) to improve interoperability between wireless network products based on the IEEE 802.11 standard.
IEEE 802.11 devices are installed in many products on the market, such as printers, laptops, and other peripherals that can provide wireless Internet access.
In 1996, Lucent, a major manufacturer of network communication equipment in the United States, took the lead in initiating the establishment of the Wireless Ethernet Compatibility Alliance (WECA), and began to create a wireless network protocol (WLAN), which was not smooth at first, and the momentum fell far behind Blue-tooth.
In 1999, WECA changed its name to the Wi-Fi Alliance, once again architected a set of certification standards, and proposed a series of specifications for wireless network technology in the industry – 802.11, including 802.11.b, 802.11.a, 802.11.
|Parameter||Wi-Fi 6||Wi-Fi 6E||Wi-Fi 7||Wi-Fi 8 (Expected)|
|Frequency Bands||2.4/5 GHz||2.4/5/6 GHz||2.4/5/6 GHz||2.4/5/6 GHz, mmWave|
|Maximum Data Rate (Theoretical)||9.6 Gbps||9.6 Gbps (2×2 MIMO)||30 Gbps (4×4 MIMO)||100 Gbps|
|Spatial reuse||OFDMA||OFDMA||MU-MIMO + OFDMA||Multi-link MU-MIMO + OFDMA|
|Target wake time (TWT)||Supported||Supported||Enhanced TWT||Enhanced TWT|
Compared with the WiFi 5 standard we use today, the wireless transmission rate of the WiFi 6 standard can reach 9.6Gbps, and high-bandwidth applications such as VR/AR, 4K and even 8K video can be easily handled.
At the same time, WiFi 6 uses OFDMA technology that is homologous with 5G, combined with 1024-QAM high-order modulation, and can support 160MHz bandwidth, nearly 3 times faster than WiFi 5.
Intelligent crossover technology can support more devices concurrently and increase the capacity of access devices by 4 times.
Multiple concurrent access devices can reduce queuing, interfere with coloring, and actively avoid it, reducing latency by 2/3.
Supports wake-on-demand function during terminal device standby, reducing terminal power consumption by 30%.
What is the difference between WiFi 8 and WiFi 6?
At present, WiFi 8 has not been successfully developed.
WiFi6 and 5G speeds are similar, with 5G speeds of 10Gbps per second and WIFI6 speeds of 9.6Gbps per second. But if based on a real scenario, the speed depends on your mobile terminal, surrounding environment, router and other factors.
Due to the problem of signal interference, indoor 5G may not be as good as wifi6 compared to the signal. So use 5G outdoors, and use WIFI6 when you go back indoors.
Wi-Fi 8 Wikipedia：Does China have WiFi8 technology?
Currently, WiFi 8 technology is not available, Wi-Fi 8 technology is not available worldwide, and no word has been released about the standards for Wi-Fi 8 technology.
WiFi technology applications
WiFi technology is widely used, such as the following:
- Application of WiFi technology in the field of cameras
WiFi camera is easier to understand, that is, the built-in WiFi function of the camera, can achieve wireless transmission, printing, etc.
WiFi8 router – Full Gigabit Mesh
WiFi SD card camera itself does not have WiFi transmission function, but supports SD card with WiFi transmission function, the camera’s operating system has built-in or supports the installation of such memory card drivers, and has the corresponding operation option, Kodak EasyShare-One.
If there is no camera with a driver and corresponding interface, even if such a card is inserted, it is useless.
WiFi SD card is actually a memory card that has the appearance of an SD card, but has a built-in WIFI wireless card, which can be used on mobile devices that do not have WIFI function but support the SD card.
