When you choose wireless router, mesh router, WiFi access point, 4G router, 5G CPE, we will ask what's the wireless frequency you want?

2.4GHz, or 5GHz or 6GHz? Single band, dual band or tri-band?

To understand the above questions before you choose a wireless router, mesh router, WiFi access point, let's clarify the different between 2.4GHz, 5GHz and 6GHz in wireless frequencies.

The primary differences between wireless frequencies are the range (coverage) and bandwidth (speed) that the bands provide.

· The 2.4 GHz band provides the most coverage but transmits data at slower speeds.

· The 5 GHz band, some times called 5.8GHz band, provides less coverage but transmits data at faster speeds.

· The 6 GHz band, introduced with the new WiFi 6E standard, provides the least coverage but transmits data at the fastest speeds of the three frequencies.

Wireless range decreases with higher frequencies because higher frequencies cannot penetrate solid objects, such as walls and floors. However, higher frequencies allow data to be transmitted faster than lower frequencies, so higher frequencies like 5 GHz and 6 GHz allow you to upload and download files faster than 2.4 GHz.

Your WiFi connection on a particular frequency band can also be affected by interference from other devices. Many WiFi-enabled technologies and other household devices use the 2.4 GHz band, including microwaves and garage door openers. When multiple devices attempt to use the same radio space, overcrowding occurs.

The 5 GHz band tends to have less overcrowding than the 2.4 GHz band because fewer devices use it and because it has 23 channels for devices to use, while the 2.4 GHz band has only 11 channels. The number of channels that are available to you depends on the wireless regulations in your region. If you’re experiencing a lot of interference from other devices, consider using the 5 GHz band.

The 6 GHz band is newly certified and is exclusive to devices that support WiFi 6E. This means that on 6 GHz, the WiFi network doesn’t need to slow down to accommodate legacy devices. The 6 GHz band also supports almost twice as many channels as 5 GHz. Fewer devices, more spectrum, and more bandwidth means less interference and network congestion.
