Even if you happen to have the best WiFi router in the world, it is useless if you don’t know exactly how to optimize it. Incorrectly positioned WiFi antennas and routers pave the way for weak WiFi signals and a restricted WiFi range.
The odds of experiencing flawless Internet connectivity are there only when you have the relevant settings in a place like a WiFi router location adjusted correctly.
WiFi transmissions are qualified electromagnetic waves, similar to your cell phone or radio. Unlike AM waves, which are hundreds of meters long, WiFi signals are only a few millimeters long, with a maximum distance of 150 feet from a source.
3 Classifications Based on Radiation Pattern
- Omni Directional Antenna
- Directional Antenna
- Semi-Directional Antenna
Omnidirectional WiFi Antennas transmit electromagnetic waves in all four cardinal directions equally. The semi-directional type of antenna emits radio waves in a specific configuration, whereas direction type antennas transmit energy entirely in a single direction. Most of the time, you will find them in wireless routers and adapters.
With respect to their placement, this type of antenna can be classified into 2 types.
- Indoor Type
- Outdoor Type
It is typical for indoor types to come in small and compact sizes. They are used in conjunction with laptops, low-energy USB-type WiFi adapters, WiFi routers, and mobile phones. Antennas for WiFi connectivity of this type, with a very low gain (usually 2dBi-9dBi), are meant for indoor use.
Outdoor types are designed for transmission and reception over long distances. They are normally placed on rooftops and are capable of transmitting and receiving radio waves over incredibly great distances. They come with a very high gain and many found on the market today are waterproof since they are intended for use outdoors.
Antenna Positioning and Placement
The position of the WiFi router’s antenna is vital to the WiFi signal speed and range. There are numerous types of WiFi routers available on the market today. Some come with a single antenna, while others have two, and some others even have eight.
Therefore, where should you place your WiFi router’s antenna to achieve a quicker WiFi network that will give you, say, good, satisfying coverage?
If your WiFi router comes with 2 WiFi antennas, you need to point one of the antennas horizontally, then let the other be in a vertical position. This will allow us to utilize both horizontal and vertical space in our homes. Another key benefit of angling WiFi antennas in this direction is that they are polarized. It is observed that the maximum signal is received when both types of equipment, receiving devices and transmitters, are identically polarized.
Polarization varies based on the WiFi antenna. The placement of your antenna will vary depending on the device; some will be horizontal, while others will be vertical. By directing WiFi antennae perpendicularly, we can maintain the same polarization in both devices regardless of where you have them.
The majority of WiFi routers have two WiFi antennae, and in an ideal world, you would position one vertically and the other horizontally. When the internal antennae of client devices like mobile phones or laptop computers are parallel to the router’s antenna, the transmission and reception of WiFi signals will be faster.
Thus, by maintaining one vertical antenna and one horizontal antenna, there is a greater possibility of connecting the client antenna with at least one of the router antennas and achieving a parallel match.
