When using gigabit broadband, many netizens find that the network speed is always not as fast as expected. Some netizens even used their mobile phones to test the internet speed, and found that the internet speed could not reach the so-called 1000M, only 433M m. Some users even said that they only had1000 m. What's the matter? Is this another routine for operators? Actually, it's not.
It is normal to have errors in the network speed test, but if there is such a big deviation that the speed is less than half, it is not a simple error, and it is very likely that our test method is wrong. First of all, we need to know the most basic network knowledge and what necessary conditions are needed to achieve gigabit network speed.
1, the network cable must meet the standard of super Category 5 or Category 6 cable.
The network cable itself has an upper transmission speed limit, which is basically a blind spot for many non-professionals. When decorating, the network cable embedded by the decoration company for each family actually plays a decisive role in the network speed of the whole family in the future. If the embedded network cable can't reach the standard of super class 5 or 6, then the network speed of home mesh can't reach the standard of Gigabit anyway. The lines connecting mesh networks and routers must also meet this standard.
2. Router is the most important thing.
Router is the core hub of home network environment, and ip address allocation and information exchange and transmission of each device are inseparable from router. Routers are very important to network speed, and there are many related factors that need users' attention.
The first is that the router itself must meet the Gigabit standard. The transmission speed of the router's intranet must reach more than gigabit, otherwise the fastest network speed will be limited after entering the router. Generally, new routers exceed this standard. Secondly, the signal selection of the router. Generally, routers adopt dual-band mode, which can support both 2.4G and 5G frequencies. If you want to reach the limit network speed, you must choose a signal with 5G frequency.
However, it is worth mentioning that with most router technologies at present, even if the signal with 5G frequency is connected, the network speed of 1000M cannot be reached. At present, the antenna of mobile phone is 2T2R (two receiving antennas and two transmitting antennas), that is, 2x2 "dual antenna" MIMO technology. When the mobile phone communicates with the router, it will transmit data with the four antennas of the router at the same time. Even so, the upper limit of transmission speed is only 866M, which is 433M (receiving speed is 433M, sending speed is 433M, adding up to a ***866M) tested by our mobile phone. If you receive a signal with a frequency of 2.4G, the speed will even drop to1100mm .. This is a problem of wireless signal technology. Theoretically, the upper limit of 1733M can only be reached if the mobile phone supports 4T4R and the number of router antennas reaches more than 8, and the router really supports 4x4 MIMO technology. However, there are not many routers on the market at present, and ordinary users buy less.
Considering the limitation of wireless network technology, it will affect the network speed test, so in order to really test the network speed, it must be carried out through wired network. As long as you use a computer with a Gigabit network port and connect a router that meets the Gigabit standard with more than 5 or 6 types of network cables, you can measure the real network speed. Under normal circumstances, it can reach the network speed of1000 m. Therefore, the network speed we measured is not accurate, perhaps it is really a misunderstanding of operators.
