What’s the difference between 2.4GHz and 5GHz wireless bands?

As Wi-Fi relies on radio waves, different bandwidths have different advantages. The Vodafone Broadband router contains clever technology which automatically switches to the channel with the least interference. You can check this in your Vodafone Broadband app.

The 2.4GHz bandwidth

  • Provides coverage over larger distances
  • Great for larger properties with thick walls where you want to access Wi-Fi throughout your home
  • Great for emails, surfing the web or chatting online
  • It’s also liable to congestion with the 13 different channels, so it may be slower than 5GHz, but you can switch channels to improve speed

The 5GHz bandwidth

  • Provides coverage over shorter distances but it’s faster as a result
  • Connection is slower the further away your device is from the router, or if your house has thick walls
  • Great for streaming, gaming or larger file transfers
  • Some older devices may struggle to connect to 5GHz
