What WiFi Antennas To Look for When You Need To

Improve Your Home’s Wireless Connectivity

wireless technologySome people find networking devices, such as routers, unappealing in certain areas of their homes. Because they are quite expensive, most homeowners ensconce them behind furniture or inside cabinet drawers. Sometimes they are placed instead in an inconspicuous corner of the house where they’re out of the way, but still out of sight. 

Unfortunately, the aforementioned places can’t be considered an optimal location for a router. Positioning your router in any of such places runs the risk of coming across an interference or something that would be getting in the way of the wireless signal.

Relocating the router or moving this particular networking device to the central location in your home is a must. It is the first step toward optimizing your home network.

If networking issues continue to persist, or if there is no possible way you can relocate your router, there are other options that can be taken into consideration. One of which is looking into different types of antennas. 

If you have a wireless gateway, a router-modem, or another device without a detachable antenna, you can connect it to a wireless router using an ethernet cable.

Increase the WiFi Antennas Signal Strength in an Office Building.

In terms of size and area, office buildings and similar workspaces are significantly larger than residential homes. Very often, these structures have more obstacles in them that get in the way of the WiFi signal, keeping it from covering the entire building.

Much like what you’d do in your home, you need to station your office router optimally, and if it comes with detachable antennas, you can have them replaced instead to improve performance and coverage. 

Printers, laptops, computers, and smartphones are all commonplace in an office. In such scenarios, the best type of antenna to use is an omnidirectional kind.

It is possible to increase the wireless signal in expansive spaces, but you need to make use of the ceiling dome antennas. Besides, you can have them in residential spaces or homes, but homeowners most of the time are not familiar with it, therefore they tend to be less common. 

Enhance Outdoor WiFi Signal

Wifi antennas signal can get blocked or can deteriorate due to big, solid objects like doors, walls, and furniture. The reason behind that is because they either absorb or deflect the WiFi signal itself. 

If you wish to extend the transmission, consider using an omnidirectional antenna outdoors. You can either link the router to the WiFi extender with the help of a POE cable. 

Alternatively, you can connect directly the extender to an outdoor access point, such as a range extender for WiFi with a POE connector.

For outdoor use, a low-gain antenna will provide you with the best coverage you can ever ask for. The design of WiFi signals is more circular, resulting in signals that are spread closer to the ground.

In the case of an antenna that comes with a high gain, it could boost the signal strength too far away, leading to a stronger signal outside your property but weaker at your location.

If what you want is to extend the reach of your wireless signal, say, for example, to a field, we suggest that you consider a directional antenna. Make sure it’s pointing in that direction.

 

How Do We Fix Interference in WiFi Antenna?

A WiFi antennas transmits signals over the airwaves. And by now most of us know that wireless connection, in comparison to being hard-wired, is most prone to interference. 

If interference occurs, two possible scenarios are waiting to happen —  your connection will be disrupted, or you’d be completely disconnected. This is the reason why a wireless connection is unstable and not secure. Good thing that there is a workaround in this kind of connectivity issue. 

Interference in a wireless network can be brought about by a gamut of reasons. It can come from your own or your neighbor’s. Or it can be induced by nearby pieces of equipment such as microwave machines and radar systems.

Non-WiFi wireless devices can cause interference, too. Indeed, many possibilities can be taken into account. 

This is the reason why tracking down the root cause of interference or fixing the same can be quite a task. However, knowing where you should start may be the first big step you need to take.   

Identifying Interference Issues Using WiFi Survey

One way to verify that your network has some kind of network issue is by conducting site surveying work. There are many ways to do that. All of which, though, would necessitate you to walk through the coverage areas of the network. 

While walking yourself around the coverage areas, you can do a spot check by making use of wireless adapters and the right apps for the job. 

Alternatively, you can check out some professional surveying programs for this purpose. Such applications will help you analyze the data you were able to gather. 

In the end, surveying programs will create substantial noise and signal heat maps, as well as SNR, overlaid on the coverage area floor plans.   

Interference Caused by Your Own Access Point 

There are occasions that the issue is within the network itself. This, by far, is considered a major interference problem with WiFi networks. A wireless network that is not properly configured runs the risks of the AP signs getting in the way of each other.  

What you’d want to have is 15% to 20% coverage to overlap between AP cells. Should it be less than that or there is completely no overlapping at all between the AP cells, it increases the odds of your network having bad signal spots. 

On the other hand, if either band has too much overlapping between its AP cells, it will induce co-channel interruptions along with a handful of other concerns.   

Migrating Other Clients to the 5 GHz Band

In general, a 2.4 GHz band would be best described as having more congestion issues and interference. This brings us to think that the 5 GHz band can assist clients to move away from interference issues, thus further enhancing the network’s overall performance. 

Aside from seeing to it that clients and APs can provide support to both bands, take into account also the possibility of using a band-steering functionality which the APs can provide.  

This functionality will have dual-band devices to make connections to nearby 5 GHz bands of the APs as opposed to leaving things up to the client itself or the user. 

Some APs allow you to enable or disable band steering. Others would allow the configuration of signal thresholds so that dual-band devices are not forced into having to use 5 GHz.  

Increasing a WiFi antenna’s transmission rate would substantially put to a minimum the level of interference that may occur. The working idea behind this is that the faster you send and receive the communication, the less interference will likely take place.
