While buying wireless routers most of the people are easily confused with appearance,Manufacturers have already grasped the misunderstanding of end users and are producing wireless devices with more antennas than one, fancier design so that customers would be confused.We will describe three common mistakes when choosing a wireless router.
Nowadays, there are more and more antennas for wireless routers on the market, and the price is that the more antennas, the more expensive. However, the more antennas, the stronger the WIFI signal will be? In fact, it is not necessarily.
First of all
Because of the manufacturer, some manufacturers think that people only judge the quality of the wireless signal based on the number of antennas. Therefore, it is useless to make some empty antennas. It looks like there are many antennas in appearance. Not so much.
The multi-antenna router is based on MIMO technology (multiple input and multiple output), and multiple antennas are available after the 802.11n protocol. The previous 802.11a, b, and g are not supported, so the previous routers are all single antennas.
After the emergence of MIMO, you can send data through multiple antennas at the same time, which is equivalent to a data packet that can be divided into multiple parts and sent out, and then received through the mobile phone, which will increase the data transmission rate. However, if your mobile phone is still the same as before If the old mobile phone does not support this technology, the signal will be worse.
In theory, if your mobile phone supports MIMO multiple input multiple output, and there are no obstacles, then the signal transmission rate must be stronger.
The more antennas through the wall, the better the function. Based on the first point mentioned above, the multi-antenna is only based on MIMO, which increases the transmission rate, and the general wireless routers are based on 2.4GHz, but there are some The wall penetration king has indeed improved the wall penetration performance, but it is not achieved through multiple antennas, but by increasing the frequency.
Now 5G WIFI has increased its frequency to 5GHz, so its wall penetration function has been greatly improved. The previous 2.4GHz wireless routers generally have no signal if they wear two walls (the two walls here cannot have glass or doors), and the 5GHz wireless routers are no problem if they wear two walls.
It’s just that the signal is much worse, but it’s hard to receive the signal if there are more than three walls. You must pay attention to this point. If there are more walls, it is recommended that you connect multiple wireless routers in series or bridge, if you have a computer. It is also good to install a portable WIFI, you only need to insert the portable WIFI into the USB interface, and then install the driver software to connect to the WIFI. Buying a wall-through router is expensive and may not reach the signal you want.
The built-in antenna of the wireless router is actually similar to the external signal, but the antenna is placed inside the device, which is safer and less susceptible to damage, and saves space. More and more manufacturers have begun to produce wireless routers with built-in antennas. Therefore, In some cases, a wireless router with a built-in antenna is better than an external one.
