2.4 GHz vs. 5.8 GHz WiFi connection

Hannah Jordan -

Have you wondered what the difference is between 2.4 GHz and 5 GHz wireless?  In our post today, we will be discussing the differences between the two, when to use them and why it is important.

If you have ever heard someone refer to a device as dual band wireless, the term indicates that a device has the capability of broadcasting both the 2.4 GHz and the 5.8 GHz frequency.

Here are a few facts about each frequency:

2.4 GHz

  • Majority of devices use 2.4 GHz
  • Has greatest distance
  • Can be crowded because of so many users (may affect speed)
  • May get interference from other devices running on the same band (i.e. microwaves, cordless phones etc.)

5 GHz

  • Limited use, but better speed
  • Many devices do not have 5 GHz available
  • Only way to achieve optimum Wifi performance
  • Less range, may need more access points
  • Can cause connection issues if all devices are not running on 5 GHz
  • Preferred for gaming and file streaming because of speed

Here are a few more facts regarding dual band:

802.11g = the device will only operate on 2.4 GHz

802.11n = the device will always operate on 2.4 GHz and some on 5 GHz

802.11ac = the device will only operate on 5 GHz

For MAC users out there, Apple offers dual band wireless on the majority of their products. When purchasing a product, make sure to check the specs on their comparison charts.  They will list the capability of each device.

It is ultimately up to each user which frequency they decide to use.  You have to look at the pros and cons of each connection, see what is available to you and what will give you the optimum performance and range.
