How Are 2.4Ghz And 5Ghz Different?

Gigahertz or Ghz is a frequency unit to measure alternating current and electromagnetic wave frequencies. 1 Mhz is equal to 1,000,000 Hz, and 1 Ghz is equal to 1000 Mhz. This was a little bit of physics. Now let’s understand these bands in simple words. 

You might be wondering what Ghz is in a laptop. The clock speed in Ghz measures how quickly the CPU can retrieve and interpret instructions.

This way, your computer knows to complete different tasks faster. You can sometimes benefit from a CPU benchmark to assess how poorly or how well your PC is performing.

2.4 vs 5

We are coming to the two bands, 2.4Ghz, and 5 GHz. Now we know about Ghz, we can quickly figure out these two bands. As the number suggests, 2.4 GHz will provide you with a slow speed, and 5 GHz will give you a faster rate.

However, it doesn’t only depend on speed but also the range it comes with.

The range tells you how much area it can cover to use the wifi. So to clear out things up, 2.4 GHz comes with a broader scope, but data transmission would be slow. And 5Ghz has a narrow range, but data transmission would be fast.

You already know how to check if my Laptop supports 5Ghz wifi. And with that, you would know what band you have been using till now on your computer.

You can see the clear difference in speed while downloading and uploading files or streaming online. If your Laptop chooses 2.4 GHz automatically, you can easily switch to the 5 GHz connection.

Also, keeping your device close to the router will give you a good speed while using the 5 GHz band.
