Do you master the correct posture of the 100mbps broadband?

Broadband is getting wider and wider. This is not a small editor who has officially accelerated to 200Mbps today. It is a coincidence that yesterday someone asked Xiaobian to push the router. The reason is very simple - the broadband at home has been upgraded. However, many small partners do not understand why 100Mbps broadband is still related to the router?

Blast Broadband Fast Track has fallen behind

First posted a broadband speed map, some people asked me a few days ago what this is measured, here also a unified statement, Baidu search "speedtest" first it wants. In addition, this test site also has a mobile phone APP, which can be found on iOS and Android.

It can be seen that broadband has exceeded 100Mbps. This is a very important node - because 100Mbps broadband will cause many routers to no longer be applicable, 100Mbps bandwidth switches and routers must be upgraded to gigabit level. This is why?

Let's talk about the speed problem. The actual transmission speed of 100mbps routers and switches is about 12.5MB/s. This speed is even worse than USB2.0. The speed of USB 2.0 is half duplex 480Mbps, so read and write plus a total of 60MB/s. One-way actual read and write is also within 30MB/s. If you have a movie on another computer on the LAN, share it and copy it to your hard drive, compared to the USB 2.0 mobile hard drive. In contrast, the theoretical transmission speed of 1000 Mbps is almost 125 MB/s (actually 100 MB/s or less), far exceeding USB 2.0. Although there is still a gap between the theoretical transmission speed of USB 3.0 and 500 MB/s, at least it will not be. It is too slow to stand.

Moreover, because there is a certain loss during transmission, the actual bandwidth often fails to achieve the nominal value performance. Imagine home broadband is 100Mbps, routing, switches are also 100Mbps, no matter how you speed can not reach the theoretical level of 100Mbps (small series test up to 80Mbps ~ 90Mbps level) - but for a Gigabit routing, Immediately you can see 100Mbps full speed test results.

Obviously, when you step into the bandwidth of Gigabit, Gigabit routing must be upgraded. In other words, Gigabit broadband with Gigabit LAN, so as to play the full performance of broadband network.

What do you need for 100M bandwidth?

To achieve a true 100Mb/GbE LAN, we must meet two requirements. The first is the network cable. The best choice for the network cable is the Super Category 5 cable.

It is easy to distinguish whether it is an ultra-five cable, and the skin is marked with the word “CAT5e”. Some flat network cables are also ultra-five, and in order to reduce their volume, they are not shielded, but even so, their anti-jamming capability is completely free of problems for home use. After all, the ultra-five unshielded network cable has less signal attenuation when compared to Category 5 cable transmissions, and the anti-jamming capability is also relatively strong. The family Gigabit LAN environment can be used without any problems.

Followed by the router, the router will also be divided into two parts. Speaking of the wired part first, it is better to use Gigabit routing. However, it should be noted that some routers are Gigabit over WAN ports, 100M over LAN ports, and then equipped with Gigabit Wi-Fi (11AC). This is a weird product. The significance of this type of product is to let you abandon the wired LAN, just rely on Gigabit WAN port to connect 100Mbps broadband, and then use 11AC high-speed wireless connection. The question of what is hot is coming. In that case, what is the significance of designing a few hundred megabytes? Some of these nondescript products also advertise that they are true Gigabits. There is nothing to say.

Finally there is the issue of Wi-Fi. Xiao Bian believes that the first is 11N 5G is not available, although much better than 11n 2.4G signal (not too much interference), but the limit speed is not worth mentioning (known as 300Mbps, and even 450Mbps, the actual transmission capacity is limited). The only choice is the 11G of 5G, which starts at 433Mbps, and the common equipment has 866Mbps. Whether it is anti-interference, response time, or absolute actual transmission speed, it can replace cable to some extent.

To sum up, if you want to achieve 100Mbps broadband, the best choice is 100Mbps broadband + Category 5 network cable + full Gigabit (WAN, LAN) network port, and with 11AC wireless routing, so that can really make 100Mbps bandwidth play a role. Well, Xiao Bian had finished the Children's Day. You have a comment in the comments section.
