It’s important for us to get a better WIFI signal whenever we use the WIFI routers?
A proper way to place antennas of the routers will affect our WiFi signal.
WiFi router with multiple antennas. How should these antennas, be pointed, to have better WiFi signal?
Wherever there is wireless technology, there is basically an antenna. Its purpose is to send and receive radio waves. The antenna is a “converter” – transforming guided waves traveling on a transmission line into electromagnetic waves traveling in free space, or vice versa
Based on our knowledge of physics, we know that when two parallel wires, with alternating currents, form electromagnetic wave radiation.
When the two wires are very close together, the radiation is very weak (the direction of the wire currents is opposite, and the induced electromotive force generated almost cancels out).
When the two wires are open, the radiation is enhanced (the wire currents are in the same direction and the induced electromotive force generated is in the same direction)
Determining antennas type of the router.
Different models of routers may have different types of antennas, such as built-in antennas, external antennas, or adjustable antennas. Before placing your router antenna, it is important to first understand the type of your router antenna for proper placement and adjustment.
For this antenna, how does its WiFi signal propagate outward?
The direction of signal propagation is perpendicular to the antenna. That is to say, the direction in which the top of the antenna is pointing is, on the contrary, the weakest signal.
Similarly, for routers, it is also recommended that the antenna be placed vertically if you want to get better results.
How to place the Antenna ?
There is also some common sense about the placement of the antennas to get a better WiFi signal that needs our attention:
- 1, the antennas of the router is directional, and the direction parallel to the antenna has the strongest signal.
2, between the antennas, do not get too close, otherwise there will be mutual interference.
3, the router antenna is not the more the better. Different antennas have different purposes, such as 2.4 GHz or 5 GHz signal. There is a limit to the MI MO (Multiple Antenna Send and Receive) supported by the cell phone, generally 2*2 or 4*4, not that you have 100 antennas in your router, a cell phone can communicate with it. Now a lot of router antennas, in fact, may be just to increase the number of bandwidths.
4, multi-antenna router, router antenna turned in different directions in order to make the signal range as large as possible, router antenna: it is recommended to be placed at an angle.
5, the number of router antennas and signal strength is not directly related. From the most basic router power point of view, due to the receipt of human radiation limitations, the Ministry of Industry and Information Technology on the router and other devices have a clear limit on the value of the radiated power.
6, because the router is basically omni directional radiation, antenna gain is relatively small, so the radiated power shall not exceed 100 milliwatts.
7, the signal is good or bad also depends on the size of the router motherboard amplifier chip. From the signal source, the router chip is responsible for sending, the higher the transmit power, the stronger the signal is naturally, the greater the coverage area!
8, regularly check and adjust the antenna
Hope these adjustments can help you improve the coverage and WIFI signal strength of your wireless network and enjoy a more stable and high-speed Internet connection.
