The Basics

What is the difference between 2.4Ghz and 5Ghz wireless?

When researching Wi-Fi, you might come across two important numbers: 2.4 and 5.

Wi-Fi service comes in two frequencies, 2.4 GHz and 5 GHz. Both of these frequencies have their positives and negatives and choosing which is right for your home and business will require some research.

Basically, the 2.4 GHz band can transmit data over a wider coverage area but at slower speeds. The 5 GHz band transmits data at faster speeds but over a more limited range.

Why is this? Higher frequencies can’t move through solid objects such as walls. Therefore, a 5 GHz wireless connection will not boast as much range as a 2.4 GHz frequency. However, if you need the fastest possible Wi-Fi connection — important if you download and upload large files on a frequent basis — the 5 GHz frequency will provide the boost you need.

A 5 GHz frequency is also less likely to suffer a slowdown because of interference from other devices. That’s because devices such as microwave ovens and garage door openers use the 2.4 GHz frequency. If you’re trying to download or upload files on a 2.4 GHz Wi-Fi connection and other devices are trying to use the same frequency, your Wi-Fi might slow significantly. Fewer devices rely on the 5 GHz frequency, so Wi-Fi connections using it are less likely to suffer slowdowns because of overcrowding.
