My friend A is a little depressed these two days, because some unpleasant happened with the female ticket when choosing the router.
The thing is this. The old router at my friend's A's home has been used for several years. The WiFi is slow and stuck. I just upgraded my home with 200M fiber. I just wanted to change the router for my home. You buy a router post, and when you are ready to place an order, "hand cheap" WeChat asked him a female ticket ...
Anyway, if a woman's ticket doesn't fit, she just got up with him. The biggest difference is:
In the end, my friend A held up the Yali and chose a favorite router according to his own preferences ... However, a few days later, my friend A didn't expect that it would be a thousand choices in the case of a football strategy. The router of Wi-Fi actually suffered from WiFi disconnection and instability, and there were friends visiting. The number of connected people was more than one, and the qualifying minutes were reduced to pig teammates.
My friend A was wondering. They all bought it according to the Raiders. Why did they step on the thunder?
In this regard, Teng Xiaomei just wants to say that he is too young too simple, online product recommendation guide can not be trusted, you need to learn to understand the little secrets behind the product parameters, antenna gain, transmit power, dual-band WiFi , Learn to understand these 3 key parameters, you can buy a route without stepping on thunder!
1. Antenna gain
Common gains on the market are 3dBi, 5dBi, and 6dBi. The antenna gain is linearly propagated by rays. Generally speaking, the larger the value, the greater the gain, and the farther the propagation. If the home is a single-storey house, the higher the gain, the more signal coverage will be. wide. However, the total strength of the signal is constant. The greater the gain, the narrower the vertical plane that can be covered. Therefore, if it is a duplex building or a villa, do not pursue high gain.
2. Transmit power
Due to the turbulence of routers on the market, various manufacturers are producing more router antennas than others, leading some consumers to mistakenly believe that "the more antennas, the better the signal." In fact, whether the WiFi signal is strong has nothing to do with the number of antennas, it is related to its own antenna gain, transmit power, chip, WiFi enhancement module and placement.
Regarding the transmit power, the greater the transmit power, the stronger the WiFi penetration and the wider the coverage, but this will not tell you generally because:
1. The transmission power of the router is generally stronger than that of mobile phones and computers. The signal is transmitted, but the mobile phone does not return, and it is still useless.
2. The Ministry of Industry and Information Technology stipulates that the transmission power of the wireless router cannot exceed 100mW (20dbm)
3. If the power is too large, the signal noise will be amplified, and the quality of WiFi cannot be guaranteed. It will also cause interference to Bluetooth and other devices.
So within the established transmit power value, even if you add 100 antennas to the router, the WiFi signal strength will not increase. Therefore, you don't have to be too entangled with the transmission power, you can buy products that pass the quality inspection.
Three, dual-band WiFi
In the past few years, routers were generally single-frequency routers, that is, only 2.4GHz WiFi was transmitted, but 2.4G WiFi interference was serious, resulting in slower transmission speed. Later, 5GHz WiFi with stronger anti-interference ability and faster transmission took advantage of the trend. Health. Moreover, most mobile phones and computers now support 5GHz WiFi. If you want to change the router at home, you must buy a dual-band router, which will bring you a "flying" general network experience.
Under normal circumstances, our mobile phones / computers can find two WiFis of dual-band routers, but because 5G WiFi penetration capacity is weaker than 2.4G WiFi, sometimes 5G WiFi may "disappear" in rooms or toilets, this time You need to manually switch to 2.4G WiFi, manual switching is still troublesome, so when you buy a router, you can choose a router that supports 2.4G and 5G WiFi dual-band integration, and it will automatically switch WiFi according to the specific environment of the device, allowing you to work 24/7 Enjoy high-speed internet.
Finally, what should I do if I encounter serious disagreements with the female ticket purchaser for routers like A?
This is simple, choose a router with strong signal coverage and good looks!
For example, the following Tenda Villa routing nova:
The appearance of this router can definitely meet the aesthetics of 99% of girls, but more importantly, Tenda Nova's WiFi coverage is powerful, and it refuses to hang up and meet all your needs.
The biggest feature of Tenda Villa Routing Nova is the use of the latest networking technology-Mesh, automatic power-on networking, all nodes are connected to each other through 5G WiFi to form a distributed grid network, each node can receive and send signals , Effectively expand the coverage of WiFi, even across floors will not cause network speed attenuation.
Tenda Villa Routing Nova uses dual-band technology to integrate 2.4G and 5G WiFi together, share a WiFi name, and automatically determine the strength of the two signals, which one is connected quickly, and millisecond-level switching, eliminating the need to manually switch WiFi The trouble of frequency band.
Not only does it achieve WiFi dual frequency integration, automatic frequency band switching, Tenda Villa Routing Nova also supports 802.11v / r seamless roaming protocol and MU-MIMO technology, which can greatly increase the bandwidth while ensuring the smooth switching of devices between different signal nodes Interest rate and increase the number of flights, no matter how many guests come from home, they will say goodbye to Caton.
