2.4GHz vs. 5.0GHz Frequencies – What You Need To Know

On April 15th the Korcett Account Management sent out their 23rd newsletter. This issue was devoted to the two radio wave frequencies that wireless internet devices run on – 2.4GHz and 5.0GHz. K.A.M. has decided that this information is to valuable not to share in a blog so property managers and residents alike can learn more about this wireless issue and how best to use their wireless network in their complexes and homes.

2.4GHz vs. 5.0GHz Frequencies

Our world is literally surrounded by radio waves. We are saturated by radio waves from Internet routers, bluetooth devices, baby monitors, microwaves… they come from Internet towers, TV stations, and even outer space.

Wireless devices run on one of two frequencies – 2.4 GHz and 5.0 GHz. The biggest differences between the two are the range, bandwidth, and amount of Interference. The 2.4GHz frequency has a higher range than the 5.0GHz frequency, but the 5.0GHz frequency lets more bandwidth pass. It makes sense that baby monitors run 2.4GHz because they need a long range to work properly. Laptops work better when more bandwidth can pass at a faster rate on the 5.0GHz frequency.

How This Effects Your Residents

Lately the 2.4GHz frequency has been over saturated with high numbers of wireless devices. Both frequencies run on channels, and 2.4GHz has only 3 non-overlapping channels (1,6, and 11). However, 5.0GHz has 23 non-overlapping channels to provide to these wireless devices.

Imagine you are a student in your apartment. You are sitting on your couch with your laptop open to do your online quiz and you are connected to the 2.4GHz frequency. Just in your apartment (let’s pretend you live by yourself), here is everything else on that frequency…

Cell phone.

Cordless phone.

Door intercom.

Two wireless Xbox controllers.


Phone bluetooth.

Tv remote.

Cable remote.

Dvd remote.

Those two Wii remotes that you don’t use anymore but are still under your couch.




Remember, just because you aren’t using a device at that moment doesn’t mean it’s not on the frequency and “talking” through radio waves. Also, these are just the devices in your apartment. Multiply those devices by all your neighbors around you when you live in an apartment building. Now, imagine you have a new laptop that runs on the 5.0GHz frequency and you can cut that list of interfering devices by 90%. It’s no wonder the WiFi will work faster when it isn’t competing with all those other factors.
