Wireless networks operate on five distinct frequency ranges: 2.4 GHz, 3.6 GHz, 4.9 GHz, 5 GHz, and 5.9 GHz. Each frequency range is divided into several channels to minimize interference and network congestion. In this regard, WiFi channels are like road lanes. Just like multilane roadways can carry greater volumes of traffic than two-lane roads, so do WiFi channels allow more users to enjoy maximum download and upload speeds at the same time.
In most countries, the 2.4 GHz frequency range, which is the most commonly used short-distance frequency range, is divided into 13 channels with 5 MHz of channel separation. In North America, the 2.4 GHz frequency range is divided only into 11 channels, but the WiFi channel width is the same as in the rest of the world.
Some WiFi channel analyzer and WiFi channel scanner apps, however, are far more reliable than others
Because each channel on the 2.4 GHz spectrum is 20 MHz wide and the channel separation is only 5 MHz, only three channels don’t overlap with any other channels: 1, 6, and 11. This is important because WiFi channel overlap is a common cause of interference and performance degradation.
Most WiFi channel analyzer and SSID scanner apps can detect which channel a WiFi network operates on and plot all nearby networks on a graph to make it obvious which channels are used the least. Some WiFi channel analyzer and WiFi channel scanner apps, however, are far more reliable than others, and some also come with unique features that make WiFi network optimization much easier.
A WiFi network introduces a variety of issues that can negatively impact your ability to connect and stay connected. These factors can also lead to network speed and security concerns that you will not face with a wired connection. Here are some of the configuration and installation concerns that you may experience when you employ a WiFi network.
What Exactly is a WiFi Channel?
WiFi routers can use two different frequency bands to produce their signal: 2.4GHz or 5GHz. Some routers are dual-band and can deliver their signal using whichever frequency you choose to employ. Each frequency contains a number of smaller frequency bands used for signal transmission. These smaller bands are referred to as WiFi channels.
There are differences in how the two frequencies perform when providing their signal to connected devices, according to lifewire.com. These differences may impact which type of router is best for your particular situation. Let’s take a quick look at what makes each frequency distinctive.
2.4 GHz frequency
Slower data transmission speed.
Larger network coverage area due to extended range.
More susceptible to interference from other household devices that use the same frequency.
The number of available channels is 11.
5GHz frequency
Greater data transmission speed.
Reduced network coverage area due to a shorter range and an inability to penetrate solid objects.
Less interference as not many other devices use the 5GHz frequency band. Sibelius 7 sounds mac download.
The number of available channels is 45.
Why do Certain Channels Incur More Interference?
The reason that certain WiFi channels may offer better performance for your connected devices is related to the interference that a particular channel may be experiencing. Interference in the work of WiFi channels comes in two flavors.
Co-channel interference – This type of interference, also known as crowding, occurs when a number of devices are competing for bandwidth on the same channel. This can cause slower than expected data transmission and dropped connections.
Adjacent-channel interference – When devices from overlapping channels are attempting to talk over each other, adjacent-channel interference can occur. The bandwidth and number of channels associated with 2.4GHz routers make these devices susceptible to this type of interference.
Why You Should Use a WiFi Channel Scanner
If you are experiencing slow data transmission speeds or dropped connections, a likely cause is interference that is impacting the channel that your router is using. Through the use of a WiFi channel scanner app, you can monitor the channels that you and neighboring routers are using and perhaps change channels. Netflix filme download auf mac.
Many users never change their router channel, leaving it at the manufacturer’s default setting. This may not be the best channel for optimal performance of your WiFi network. Logging into your router lets you change the channel that it will use to transmit its signal. Changing it randomly may solve your issues, but you are far more likely to succeed with the information gleaned from scanning the channels.

In areas where there are a number of routers with overlapping ranges, moving to an unused channel can dramatically improve the reliability and speed of your WiFi network. Apartment dwellers are particularly prone to having their networks impacted by other routers. Let’s find out how to use a WiFi scanner app to locate the best channel for you to use.
Using KisMAC to Scan Your WiFi Channels
KisMAC is an open-source, freeware WiFi channel scanning tool that can help you tune your router and find the appropriate channel for your network. It is designed for the Mac and is designed for use by experienced network security professionals. The tool has powerful capabilities beyond that of channel scanning, and its use is prohibited in some European countries.
You may need to use an additional network card as KisMAC does not support some of the cards installed on newer Macs. Once you have KisMAC up and running, initiate a scan of all nearby WiFi networks. Detailed information regarding each network will be displayed in the application’s window, including the channel that the router is using. You can use this information to make an informed decision about which channel you should configure your router to use.
