What frequency is iPhone hotspot?

The iPhone’s personal hotspot feature allows you to share your iPhone’s cellular data connection with other devices like laptops, tablets, and other phones. This can be extremely useful when you need internet access but don’t have access to Wi-Fi.

What frequency is iPhone hotspot?

The frequency band that the iPhone uses for its personal hotspot can impact connectivity and internet speeds. Knowing what frequency band your iPhone uses can help troubleshoot connectivity issues.

In this comprehensive guide, we’ll cover everything you need to know about what frequency band the iPhone hotspot uses and how it impacts performance.

Overview of iPhone Hotspot Frequencies

The iPhone can broadcast its personal hotspot on either the 2.4GHz or 5GHz frequency bands.

2.4GHz Frequency Band

  • The 2.4GHz band is the older and more widely adopted frequency band.
  • It has a longer range than 5GHz, allowing devices to connect from farther away.
  • However, 2.4GHz is also more prone to interference from other devices like microwaves, cordless phones, Bluetooth devices, and more. This can negatively impact internet speeds and connectivity.
  • The 2.4GHz frequency is compatible with almost all WiFi devices like laptops, tablets, and other phones.

5GHz Frequency Band

  • The 5GHz band is newer and less congested than 2.4GHz.
  • It has a shorter range but can provide faster top internet speeds and less interference.
  • However, the shorter range means devices need to be closer to connect. Walls and floors will degrade the signal faster.
  • Some older WiFi devices may not be compatible with 5GHz.

iPhone Hotspot Frequency Configuration

The iPhone allows you to configure which frequency band to use for the personal hotspot in the device settings. Here are the steps:

  1. Open the Settings app on your iPhone.
  2. Tap on “Personal Hotspot”.
  3. Tap on the toggle next to “2.4GHz Band” to enable or disable the 2.4GHz frequency band.
  4. Tap on the toggle next to “5GHz Band” to enable or disable the 5GHz frequency band.
  5. Tap “Done” to save the settings.

With both frequency bands enabled, your iPhone will automatically choose the best frequency based on factors like signal strength, interference levels, and device compatibility.

I recommend leaving both enabled to allow your iPhone to intelligently choose between 2.4GHz and 5GHz based on the current conditions.

However, if you are having connectivity issues, you can try disabling 2.4GHz and forcing 5GHz only. Or if your devices are not compatible with 5GHz, you can disable it and force 2.4GHz only.

Optimal Frequency Bands

So which frequency band is best for the iPhone hotspot? Here are some general guidelines:

Use 5GHz for faster speeds

If all your devices are compatible, use the 5GHz band when available for the fastest hotspot speeds. The less congested 5GHz spectrum means your cellular data speeds will not be bottlenecked by WiFi.

However, keep in mind the shorter range of 5GHz when moving farther from your iPhone.

Use 2.4GHz for broader compatibility

If you need to support older laptops, tablets, or phones that are only compatible with 2.4GHz, use the 2.4GHz band to ensure connectivity.

While 2.4GHz may offer slower speeds than 5GHz, it will provide the broadest device compatibility. The longer range also helps maintain connectivity as you move away from the iPhone.

Let iPhone decide automatically

For the best of both worlds, allow your iPhone to choose between 2.4GHz and 5GHz automatically based on current conditions.

This allows it to select 5GHz when available for peak speeds, but fall back to 2.4GHz when a device is incompatible or the signal is weak.

Troubleshoot with band selection

If you are running into personal hotspot issues, manually selecting 2.4GHz vs 5GHz frequency bands can help troubleshoot.

For example, if 5GHz is providing spotty connectivity, try switching to 2.4GHz only and see if that resolves the issue. Or if speeds are slow on 2.4GHz, try forcing 5GHz only.

Band selection gives you more control to workaround any configuration or device compatibility issues.

Frequency Bands for iPhone Models

Here is a breakdown of which frequency bands are supported by different iPhone models:

  • iPhone 5: 2.4GHz only
  • iPhone 5c: 2.4GHz only
  • iPhone 5s: 2.4GHz only
  • iPhone 6/6 Plus: 2.4GHz and 5GHz
  • iPhone 6s/6s Plus: 2.4GHz and 5GHz
  • iPhone SE (1st generation): 2.4GHz and 5GHz
  • iPhone 7/7 Plus: 2.4GHz and 5GHz
  • iPhone 8/8 Plus: 2.4GHz and 5GHz
  • iPhone X: 2.4GHz and 5GHz
  • iPhone XR/XS/XS Max: 2.4GHz and 5GHz

As you can see, 5GHz support started with the iPhone 6 generation. So if you have an older iPhone model, it will be limited to 2.4GHz only.

The latest iPhone models support both 2.4GHz and 5GHz for maximum compatibility and performance.

Optimizing Your Hotspot Connection

Here are some general tips to get the best performance from your iPhone’s personal hotspot:

  • Minimize obstacles between devices: Keep your connected devices in line of sight to the iPhone to maintain the strongest signal on either 2.4GHz or 5GHz. Walls and floors degrade wireless signals.
  • Move closer to iPhone: Getting closer to your iPhone can help boost signal strength, particularly if using 5GHz band which has a shorter range. Even a few feet closer can make a difference.
  • Avoid interference sources: Other wireless signals and devices like Bluetooth, microwaves, baby monitors, cordless phones, etc. can interfere with 2.4GHz WiFi. Try to distance or power down potential interference sources.
  • Disable bandwidth-intensive functions: Temporarily turning off things like iCloud backup, iOS updates, app updates, and streaming can allocate more bandwidth to your personal hotspot devices.
  • Upgrade to latest iOS: Apple improves hotspot performance and compatibility across iOS versions. Always run the latest iOS update.
  • Configure compatible settings: Use WiFi and Bluetooth 5.0 for best compatibility with iPhone hotspot capabilities. Enable WiFi Multiband in networks settings.
  • Reset network settings: If your iPhone shows connectivity issues, try resetting all network settings back to default. This will clear any problematic cached data.
