WIFI upgrade router will enter a new era



The world's first 802.11ad wireless router

At the 2016 International Consumer Electronics Show, the world’s first 802.11ad wireless router was unveiled. Its biggest feature is its ability to provide 7Gbps wireless transmission rates and spike all wireless routers on the market today.

What is the 802.11ad standard?

The 802.11ad standard, also known as WiGig, is a member of the wireless transmission protocol family. Compared to 802.11n (which operates in the 2.4 GHz and 5 GHz bands) and 802.11ac (which operates in the 5 GHz band), it works in the 60 GHz band. With ultra high wireless transmission rate.

How does the new standard router work?

Routers that meet this standard, supporting both 802.11ad, 802.11ac, and 802.11n standards, are truly tri-band wireless routers. For close-range applications, working in the 60GHz band can provide up to 4.6Gbps of wireless transmission rate, which allows users to transmit a 4K ultra-clear film in just a few minutes, only a few seconds to transmit thousands of photos; and for long-distance applications The router is transformed into an 802.11ac/n wireless router, which provides a wireless transmission rate of 1733 Mbps in the 5 GHz band and 600 Mbps in the 2.4 GHz band. The addition of three frequency bands allows the theory of up to 7 Gbps to be achieved. Transmission rate.

Will the new standard "unified rivers and lakes"?

the answer is negative. As we all know, the higher the frequency, the weaker the ability to penetrate the wall. The ability of the 802.11ac signal to pass through the wall in the 5GHz band is already very poor, and there is a clear difference from the 2.4GHz 802.11n. The 802.11ad wall penetration capability at 60 GHz is bound to be weaker (the experiment has also proved that the 60 GHz carrier diffracting ability is very poor, the signal is very attenuated in the air), and it can even be considered that it has no wall penetration ability and is only suitable for one room. Used internally.

However, the features of 802.11ad have other uses than high-speed Internet access. Although 802.11ad's high-frequency signals are not very good at passing through the wall, the extremely high bandwidth and low latency make 802.11ad suitable for streaming ("streaming" is an instant video playback technology that can be viewed while downloading. Saves waiting time for high bit rate 4K video, so some smart TVs, HD boxes, smart NAS (network storage) may be the first to support 802.11ad, and 4K video wireless streaming.

The 802.11ad protocol is not the end of the wireless standard. As an enhanced version of 802.11ac, the 802.11ax standard that uses MU-MIMO, operates in the 5GHz band, and has a wireless transmission rate of up to 10Gbps has already begun to emerge.
