Directional vs. Omni Directional WIFI Antennas

Almost everyone now relies on their internet speed to go through their daily tasks. If you use Wi-Fi, then you most likely wish you can optimize it to provide you with the best internet speed. 

Antennas are one important aspect of Wi-Fi and can be the difference between whether you have a good speed or not. There are two types of Wi-Fi antennas namely directional and omnidirectional antennas. 

In this article, we will discuss both wifi omnidirectional antennas and directional ones to help you better understand them. So, you can use them to make your connection work even better. 

Routers and Antennas

There are several types of routers and they all have antennas. Without an antenna, your router most likely won’t work properly. You may think yours doesn’t have one because you can’t see it. However, this isn’t true. The antenna may be external or internal. If you can’t see it, then yours is internal. 

Sometimes, if your router isn’t working optimally, you may consider changing the antenna. This is why you need to know the options available to you so you can select the ideal one for your situation. 

Directional Antennas

As you can guess by the name, antennas like these focus on a particular direction. Hence, both the receiver and sender have to be placed such that they both send and receive signals from one direction.  

They can be likened to a flashlight. With them, the signal is focused directly towards a particular location. The signal can then be targeted more intensely. 

This means because the antenna’s focus is direct and concentrated in 1 direction; the power of the signal being received can be increased even though the distance is far. While the distance can be vast between the receiver and sender, the coverage angle is limited. 

They are ideal for connections like point-to-point where 2 antennas are applied. One transmits the hotspot while the second connects to the transmitted hotspot. Both of them have to be pointed directly at themselves so that the connection would be almost perfect. This would make the bandwidth a lot higher.

One benefit of this type of antenna is that because it focuses on one direction, a lot of people don’t have access. This makes it more secure. 

Uses

Mainly, they are used to make the connection to far distance possible. This makes them a great option for the outdoors. However, they can be used inside buildings, especially to focus on specific places like connecting 1 floor to the other. 

They are preferable to omnidirectional ones in certain situations including: 

  • Point-to-point connection 
  • When security is important 
  • Connecting/broadcasting a hotspot over a long distance 
  • Connecting/broadcasting a hotspot when the location is known

Omnidirectional Antennas

Omnidirectional antennas are more commonly used and are most likely what you have in your home and your router. Unlike directional that focus on just one direction, an omnidirectional antenna distributes signal equally in all directions. 

While directional antennas signal is cone-shaped, the shape of an omnidirectional one is spherical. The perfect analogy for them is light bulbs. 

Let’s say you have a router with this type of antenna in your home, every angle and corner of the house will receive signal from the router. When you are connected to them, you can go round in circles, walk upstairs, or go down to the basement, and you’d keep receiving signal. 

This makes it an ideal option when you are on the move in a vehicle like a camper, Semi-cab, or RV. Also, they are ideal in situations when you aren’t sure of where the signal is being originated. This is because they can receive signal from all directions. Hence, they most likely will get the signal from whatever direction it is being broadcasted from. 

Finally, they are the ideal choice when the hotspot is being broadcasted from a central point to every part of the area e.g. in the home, fairgrounds, and park. 

Uses

They are mainly used to broadcast signal regardless of the direction of the device as far as it is within coverage. Hence, they are used in mesh systems, wireless repeaters, Wi-Fi networks, and other devices that can be connected to a router. Generally, they are used domestically.  

So, if you aren’t experiencing great network speed in your home until you are in a particular direction, then you are likely working with a directional antenna. If possible, you can change to an omnidirectional one to enjoy better internet speed from all angles of your home.

Conclusion

Antennas are crucial for your Wi-Fi to work properly. The antenna your router has may either be directional or omnidirectional. Directional ones provide a wide range of coverage but a limited direction. You may step outside your home and still receive signal as far as your device is in the right direction. But omnidirectional ones provide coverage from all directions but because of this, it doesn’t cover much distance. The one you go for should be based on your preference and needs.
