I believe many of my friends will often hear that "WIFI is supported" is frequently asked when purchasing mobile phones and laptops ". In fact, WIFI is a wireless networking technology. In the past, it was connected to a computer through a network cable, but now it is achieved through wireless signals. The most common device should be a wireless router. Within the effective range of the wireless router signal coverage, we can use WIFI connection to enjoy the internet. Then how is WIFI set up?
Generally, when setting up a wireless network, users will use a wireless network card and an AP, so that they can use a wireless mode to work with the existing wired architecture to share network resources, however, the cost and difficulty of setup are much lower than those of traditional wired networks. If the network environment is an equivalent network of several computers, you do not need to use an AP. You only need to assign a wireless Nic to each computer.
Although the distance between Wireless WIFI is not long, when the network is fully set up, the actual working distance using the 802.11b standard can reach more than 100 meters, it can also solve data error correction and error codes during high-speed mobile, while switching and security authentication between Wi-Fi devices and devices, devices and base stations are well solved. Currently, the wireless standard has gone from the 802.11g to the 802.11n standard. All products use the 802.11n standard because it can provide users with faster and more reliable wireless connections. Compared with the 802.11g standard, the speed of 802.11n is seven times faster than that of Ethernet. In addition, it has a larger coverage. The 802.11n standard can bring the bandwidth to its limit and enable wireless multimedia distribution technology for HD videos, audios, and data streams. It also provides concurrent dual-frequency operations to provide more channel capacity for your broadband multimedia applications.
At present, the trend of products on the market to 802.11n is becoming more and more obvious, and the launched products are quite attractive in terms of performance or price. The rapid development of 802.11n has led many vendors to see business opportunities. More and more vendors have added 802.11n technology to HDTV, set-top boxes, and media adapters, which has greatly promoted the entire WIFI application.
