Friend Xiao A was a little depressed these two days, because there was some unpleasantness with the female ticket when choosing the router.
This is the case. The old route of the friend Xiao A’s home has been used for several years. The WiFi is slow and the card has just been upgraded to 200M fiber. I want to change the router for the home, so I went online to find various teachings. You buy a router post, when you are ready to place an order, "handcuffs" WeChat asked about his female ticket...
Anyway, a woman’s vote is not like a woman’s ticket, so the biggest difference lies in:
Finally, a friend Xiao A withstood the pear, and picked a favorite router according to his own preferences... However, after a few days, the friend A was never thought of, in the case of doing enough Raiders, thousands of choices. The router actually showed a situation where WiFi was dropped and unstable, and there were friends who came to visit. The number of people connected was more than one, and it was a pig teammate in minutes.
The friend A is puzzled, obviously bought according to the Raiders, how can I still step on the thunder?
In this regard, Teng Xiaomei just want to say, he is still too young too simple, online product recommendation Raiders can not be trusted, buy a router you also need to learn to understand the small secret behind the product parameters, antenna gain, transmit power, dual-band WiFi , learn to understand these 3 key parameters, package you buy a route does not step on thunder!
First, the antenna gain
The common gains on the market are 3dBi, 5dBi, and 6dBi. The antenna gain is linearly propagated. Generally, the larger the value, the larger the gain and the farther the propagation. If the home is a single-story house, the gain will be higher. wide. However, the total intensity of the signal is constant. The larger the gain, the narrower the vertical surface that can be covered. Therefore, if it is a duplex building or a villa, do not pursue high gain.
Second, the transmission power
Due to the current mix of routers on the market, manufacturers are more than any router antennas produced, causing some consumers to mistakenly believe that "the more antennas, the better the signal." In fact, whether the WiFi signal is strong or not 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 position.
Regarding the transmit power, the higher the transmit power, the stronger the WiFi wall penetration and the wider the coverage, but this will not tell you because:
1. The transmit power of the router is generally stronger than that of the mobile phone and the computer. The signal is transmitted, but the mobile phone does not transmit, but it is still useless.
2. The Ministry of Industry and Information Technology stipulates that the transmission power of the wireless router shall not exceed 100mW (20dbm)
3. If the power is too large, the signal noise will be amplified, and the WiFi quality cannot guarantee that it will cause interference to devices such as Bluetooth.
Therefore, within the given transmit power value, even if you add 100 antennas to the router, the WiFi signal strength will not increase. Therefore, for the transmission power, you don't have to worry too much. You can buy a qualified product.
Third, dual-band WiFi
In the past few years, routers are still single-frequency routers, that is, only 2.4GHz WiFi is transmitted, but 2.4G WiFi interference is serious, resulting in slower transmission speed, and later 5GHz WiFi with stronger anti-interference ability and faster transmission speed. 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 phone/computer can search for two WiFi of dual-band routers, but because 5G WiFi is weaker than 2.4G WiFi, sometimes 5G WiFi in the room or toilet may “disappearâ€, this time Need to manually switch to 2.4G WiFi, manual switching is still more troublesome, so you can choose to support 2.4G and 5G WiFi dual-band router when purchasing a router, it will automatically switch WiFi according to the specific environment of the device, let you around the clock Enjoy high speed internet.
Finally, what should I do if I encounter serious disagreements when I am dealing with a female ticket like a small A?
This is simple, choose a router with strong signal coverage, and a good looking router is not enough!
For example, the following Tengda villa route nova:
The appearance of this router can definitely meet the aesthetics of 99% girls, but more importantly, Tenda nova's WiFi coverage is powerful, and it refuses to drop the line to meet all your needs.
The biggest feature of Tengda Villa routing nova is the use of the latest networking technology - Mesh, power-on automatic networking, all nodes are connected to each other through 5G WiFi, forming a distributed mesh network, each node can receive and send signals at the same time Effectively expand the coverage of WiFi, even if it is across the floor, it will not cause the network speed to decay.
Tengda Villa routing nova adopts dual-band integration technology, which integrates 2.4G and 5G WiFi, shares a WiFi name, automatically judges the strength of two signals, which one is connected, and the millisecond level switches, eliminating the need to manually switch WiFi. The trouble of the frequency band.
Not only has WiFi dual-band integration, frequency band automatic switching, Tenda Villa routing nova also supports 802.11v/r seamless roaming protocol and MU-MIMO technology, which can greatly improve bandwidth while ensuring smooth switching between different signal nodes. Interest rates have increased with the amount of capacity, and the number of guests coming from home is not afraid. From then on, we will say goodbye to the network.
