We usually use bridges to amplify signals in places where wireless networks cannot reach them.
But no matter how good the bridge is, it aims to maximize the increase and minimize the loss. Unfortunately, as long as it is extended one more layer, it will still consume too much power.
The simplest verification is to test the network speed of your mobile phone. The native mobile phone connection through the Sim card may be 100MB. When opening a wireless base station for others to use, they may have 60~80MB left when testing the connection, or it may be lower.
Native wireless Wi-Fi is already subject to loss, not to mention the addition of an additional set of APs through bridging, so the loss is doubled.
Many bridges are used to achieve reception from all corners, but the end has been transmitted through multiple bridges. Although the received signal is full, the connection speed has been reduced to an extremely low level, most likely even 1MB. No, then what is the purpose of bridging?
In recent years, power line network bridges have been developed, which are paired with Group AB devices and connected through a single power grid loop through the socket. It is no longer a traditional wireless amplifier.
But after the actual test, because Taiwan’s power distribution is a lot of mess, especially the early plumbers who had many wild ideas, the internal wiring can only be said to be works of art, so it is really not recommended to buy this kind of power bridge for network connection. road increase.
However, Google Wi-Fi is very interesting. Although it is also used for WiFi amplification, it is no longer a tree-like layer-by-layer connection method, but a mesh-like mutual support for multiple connections, and it also has an additional internal computing method. , used to reinforce devices that need to receive wireless Wi-Fi in order to achieve the fastest connection with the lowest loss.
In the traditional Wi-Fi connection mode, the first device provides the signal, and the second device forwards the network signal so that the back-end device can connect to the Internet. It is continued in a tree-like manner, with different network segments in the middle. , different wireless network names are called "Tree Network".
Tree-like networks can handle the management of a large number of devices very well, but if a node fails, the entire network connection will be interrupted, and there will be problems such as signal network speed degradation.
In a Mesh Wi-Fi network, each node can be directly connected to other nodes to form a "Mesh Network."
It is a network architecture where every device is connected to each other, allowing the intranet to be fully integrated. The system determines how to connect the back-end devices, and the connection efficiency will be better. The mesh network has a high degree of flexibility and reliability, even if If some of the nodes fail, other nodes can still continue to connect, which can provide better Wi-Fi coverage and better network connection stability.
If the average home is not very big, general wireless Wi-Fi will be enough if it is within 15 square meters. However, if the number of square meters is too large and there are different floors, it is really recommended to use a mesh network for the network. The increase is used.
Google is selling out old models these days. If you are interested, I highly recommend you to get one and play around.
My personal test found that there is almost no loss. I use the all-you-can-eat 4G network of ordinary mobile phones and connect through the Google Nest Wifi Router. Even if I am on the fourth floor and the internal line reception is weak, I can still run 100MB faster. It can be seen that This machine is very good.
If you usually only use fiber optic 100MB, switching directly to an all-you-can-eat mobile network should also save you a lot of money.

Therefore, using TP-Link to plug in a Sim card and enjoy all-you-can-eat Internet, you can already reach every corner of your home and enjoy high-speed Internet access.
For now, I can give up Chunghwa Telecom temporarily and pay monthly for 100MB optical fiber. When the satellite network becomes popular one day, if it were not for the company's security, the general fixed network should be completely replaced!
