Hello, everyone!
Today, I will continue to write about WiFi. In this article, I will explain WiFi devices and antennas placement.
WiFi network coverage is very important. It depends on the location of the WiFi device - ONU or router.
When we talk about the coverage of an apartment, whose area is less than 130 m2, ONU or router can be in the middle of the apartment (usually in the hallway) or in the room where most time is spent (e. g. living room). If the device is placed in the middle of the apartment, there will be approximately equal coverage in all rooms (depending on the furniture, doors, walls, etc.). If the device is placed in the room where most of the time is spent, we get a well-covered area. Both variants have advantages and disadvantages. We can see these situations in figure 1.

If we need to cover 2 levels/apartments in the house, the best solution is to use an additional device. A router (repeater) is connected to the ONU or another router (repeater) is connected to the router. There is another solution to this situation, but it is not the best solution. It is the routing of one or more antennas of a WiFi device. Figure 2. shows us antennas placement.

The following rules should be followed when installing the WiFi device:
The device must not be on the floor or in the corner of the room, but should be at a height of 1 m from the floor.
The device should be at a minimum distance of 30 cm from the wall.
The device must not be on any device (STB, ONU, DVD player, etc.) or near any interference devices (router, microwave oven, cordless phone, etc.) – due to heating and interference.
The device must not be in a closed box – especially not in a metal box, etc.
