What do I need to pay attention to when upgrading the WiFi signal of a duplex room?

Today, Wi-Fi has become an indispensable tool in people's lives. However, for some netizens who have a duplex room, wi-Fi connection failures often occur in some rooms, which undoubtedly causes great troubles for their connection experience. Next, let's take a look at how to maximize the energy efficiency of the purchased wireless router in the duplex room type environment to achieve better Wi-Fi signal performance.

Note 1: the location of the Wireless Router

A duplex apartment is usually composed of two upper and lower floors and multiple rooms. In view of the relentless wall and floor slabs, do not expect wireless routers to be placed anywhere, all of them can achieve the best Wi-Fi signal coverage and transmission speed. Therefore, in this environment, pay more attention to the placement of wireless routers.

As Wi-Fi is transmitted through radio waves, as the transmission distance increases, Wi-Fi also degrades, when it encounters an obstacle, reflection, refraction, or diffraction may also occur, reducing its transmission range. Therefore, do not hide a wireless router in the corner of the room, or bury it in the basement or in the shelve, instead, try to place the wireless router in the center of your wireless activity.

For the duplex room, try to place the wireless router in the center of the room

So how can we identify such a central location?

In fact, the simplest way is to observe through your line of sight, that is, where you can see the most room scenarios, then this location should be placed in the center of the wireless router.

Place the wireless router at point B to obtain a larger Wi-Fi coverage area.

For example, if you place a wireless router on a, the black part in the figure is the area where the Wi-Fi signal is not covered. In order to maximize the Wi-Fi coverage, instead, the wireless router should be placed at point B.

NOTE 2: Antenna placement Angle

Another factor that affects Wi-Fi signal coverage performance may be ignored by some netizens, which is the placement angle of the router antenna.

Today, most wireless routers on the market are equipped with an omnidirectional antenna, which is generally a standard dipolar antenna. This kind of natural signal waves often present three-dimensional "ring" coverage. Therefore, when the antenna is straight, the signal coverage in the horizontal direction is wider, while the signal coverage distance and intensity are not very good at the top and bottom of the antenna.

Simulation of Wi-Fi signal propagation when an omnidirectional antenna is set up

Take a 4-antenna wireless router as an example. When the two antennas on the back are 45 degrees out, and the two antennas on the side are placed upright, wireless signal coverage. At this time, there will be blind coverage areas on the floor under the vro, And the Wi-Fi signal will not be very good.

What is the coverage of wireless signals when two antennas are placed upright at a 45-degree angle outside the back?

Figure A: Wi-Fi signal coverage after placing the antenna according to the above conditions

If two antennas on the side are placed horizontally, the wireless signal of the router will be overwritten as shown in Figure B, we can avoid wireless blind spots in the lower floor of Figure A as much as possible. Therefore, we recommend that you use them in the duplex room.

If two antennas on the side are placed horizontally, the wireless signal coverage downstairs can be taken into account (this antenna placement method is recommended)

Similarly, for users who have an external wireless network card for a PC or laptop, in addition to adjusting the antenna of the router, pay attention to adjusting the orientation of the external wireless network card, it will also effectively improve the Wi-Fi signal sending and receiving effect.
