In 2.4 GHz, the width varies from 20 to 30 MHz and the center frequency is separated by 5 MHz. In the US, for example, channels 12, 13 and 14 in the 2.4 GHz band cannot be used.Įach channel has a width and a separation. The number of channels available on each frequency band differ because of different country regulations. A channel is the specific frequency range used by two communicating stations to pass information between them. To understand better the concept of interference, we need to talk about channels. This would be considered background noise and it can degrade the signal quality as well. Imagine also that there’s a loud song playing.

It’s like when you’re in a room full of people and you’re listening to a conversation where everybody is talking at the same time.
In wireless communications, the signals of multiple transmitters can overlap and interfere with each other, resulting in poor signal quality. Interference is in fact, the most common cause for performance and stability problems in wireless networks, so let’s talk about it next. You can also determine which frequency and channel other networks nearby are using and determine if it is necessary to change or adjust your configuration to mitigate possible interference. WiFi Explorer can help you verify that your network is operating in 2.4 GHz, 5 GHz or dual-mode, particularly if you’re using the same name (SSID) for both wireless networks. Also, consider the requirements of your wireless network and decide whether you need a wider coverage or higher throughput. If you are troubleshooting or setting up a new wireless network, make sure you know which band is supported by the different wireless devices to ensure they can connect to the network using the frequency of your choice. streaming your favorite shows in Netflix) and the distance between devices is shorter. On the other hand, 5 GHz is a good alternative when there’s a need for higher throughput (e.g. It is also the only choice if you need to connect older devices. walls) in between the access point and the client device. Older models, however, as well as older wireless clients such as iPhone 4 and 4S only run in 2.4 GHz.īecause 2.4 GHz has a wider range (the lower the frequency, the wider the range), it is suitable for deployments where there are too many obstacles (e.g.

Most modern devices and wireless network adapters, including the built-in Wi-Fi card in modern Mac computers, can operate in dual-mode, in other words, can operate using the two bands simultaneously. Most of the devices we use daily can operate in one of two different bands: 2.4 GHz or 5 GHz. The band is the set of frequencies used by the radio device to communicate wirelessly.

If necessary, please refer to your device’s User Manual for instructions on how to change the configuration of your wireless network. Keep in mind that if any configuration changes are required, you must have them done in the access point or router itself. In this post, I’ll try to summarize the most important aspects that need to be considered when optimizing a wireless network and how you can use WiFi Explorer to diagnose connectivity or stability issues. However, there are many factors that influence the performance of wireless networks and getting the most out of them is not an easy task. Wireless networks are everywhere and we use them everyday.
