Application and Analysis of Gigabit Wireless Network Cards

Now we will analyze the market and highlights of Gigabit WiFi:

First, from the frequency band, ordinary 2.4G wifi transmission rate is only 150mbps and 300mbps, and the bandwidth is limited, and the interface is only usb2.0, but for wireless transmission, especially some low-end network products, or enough Used, after all, cheaper prices.

With the advent of the 5G era, wifi has become an integral part of people's lives. Walking on the road, on the bus, and on the subway, most of the people who are everywhere are busy playing mobile phones. Wifi has been gradually changing from the original 2G, 3G and 4G now towards 5G.

The wireless network card has also been upgraded from 802.11b/g/n to 802.11a/b/g/n, 802.11ac. When it comes to 11ac, it has to be said that the change is very fast. The original 11AC is 433MBPS, which is what we said. At 600mbps, 1200MBPS is already in use, and the speed and market demand for new technologies are growing at a rapid rate.

What are the characteristics of Gigabit Ethernet?

1) The first bandwidth is close to twice the 2.4G

2) Band dual-band 5.8G compatible with 2.4G, and the agreement is to upgrade 11ac; common network card is only 11b/h/n

3) The transmission rate can reach 300 mbps in the 2.4G band; the Gigabit wifi in the 5.8G band is 867 mbps; and the Gigabit can use 11AC, but the 2.4G does not.

4) Interface is different, 2.4G is USB2.0, Gigabit wifi as 5.8G 11AC series transmission interface is to upgrade USB3.0 interface

However, it can not explain 2.4G is not good, 2.4G in the transmission of data, the distance is still possible; but when watching high-definition video speed is not so optimistic, after all, bandwidth is limited; 5.8G is a relatively wide bandwidth, to solve Watch high-definition video troubles, if you take 1200mbps to beat analogy, in the same case, the speed will be more than 4 times faster than an ordinary network card; also compatible with 2.4G.
