Our article explains how the right channel can drastically improve your online experience and recommends the WiFi channel scanner for iOS so you can get started right away.

What Is the Best Wireless Channel to Use?

Determining the best wireless channel to use isn’t too challenging, but it does require a basic understanding of how WiFi networks operate. Most consumer routers traditionally operate on two main bands: 2.4 GHz and 5 GHz. The 2.4 GHz band is older and more congested, but it has a wider range. On the other hand, the 5 GHz band is less crowded and can deliver faster speeds, but its signal doesn't travel as far.

In North America, the 2.4 GHz band extends from 2,401 MHz to 2,483 MHz, and it's divided into 11 channels, each spaced 5 MHz apart from one another. Because each channel is 20 MHz wide, adjacent channels overlap, which can lead to signal interference.

As a result, it's typically recommended to use channels 1, 6, and 11, as these are the only non-overlapping channels in the band. The 5 GHz band is divided into 24 non-overlapping channels, each with a bandwidth of 20 MHz, giving you more options for avoiding interference.

In 2020, the Wi-Fi spectrum was expanded to include the 6 GHz band, also known as WiFi 6E. This band offers an additional 1,200 MHz of spectrum and 59 non-overlapping 20 MHz channels, drastically reducing the chances of interference and congestion.

The newest advancement in WiFi technology is IEEE 802.11be, known as WiFi 7, operates in the 2.4, 5, and 6 GHz frequency bands, offering Extremely High Throughput (EHT) and catering to both indoor and outdoor WLAN operations.

But which wireless channel is the best one? The answer is simple: the one that’s used the last, and that’s something any iPhone WiFi channel scanner can tell you. Once you know what the least used channel is, the only thing remaining is to learn how to change your WiFi channel.

Why Would I Need to Use a Wi-Fi Channel Scanner for iOS?

A WiFi channel scanner for iOS lets you analyze the performance of the network to which your device is currently connected. For example, you can use it to gather detailed information about its configuration, measure vital metrics such as download and upload speeds and latency, create a coverage map of your network, and more.

Armed with this knowledge, you can engage in effective WiFi channel planning. This process involves selecting a channel that minimizes interference and maximizes performance based on your specific environment and usage patterns.

How to Scan for Wi-Fi Channels on iPhone or iPad

Due to restrictions imposed by Apple, third-party applications cannot collect comprehensive information about all available WiFi networks without the use of an additional hardware device. One exception to this rule is Apple’s own AirPort Utility, which does not require any external hardware to perform network scans.

Here’s how to use the AirPort Utility for scanning WiFi channels on your iPhone or iPad:

  1. Download the AirPort Utility from the App Store.
  1. Open the Settings app and scroll down until you see the AirPort Utility.
  1. Click the AirPort Utility option and turn on the WiFi scanner.
  1. Launch the AirPort Utility app and tap the WiFi Scan button.
  1. Tap the Scan button and wait for the AirPort Utility app to gather information about nearby networks.
  1. Tap the Stop button once you’ve collected enough data and analyze the results.

If the AirPort Utility doesn’t offer what you’re looking for in an iPhone WiFi channel scanner, then you should explore other ways how to find best WiFi channel. For example, NetSpot is widely considered to be the best WiFi channel scanner for Android, Mac WiFi channel scanner, and WiFi channel scanner Windows, and these versions of the popular iOS app are capable of displaying information about all available WiFi networks.

Top 5 Best WiFi Channel Scanners for iOS

The App Store is home to many WiFi apps for iPhone and iPad, but they all share one important limitation: they can’t analyze live WiFi data of any other network besides the one you’re currently connected to — at least not without an additional hardware device connected to your iPhone or iPad.
