WiFi frequencys uses different bands to provide different levels of ranges and speed to the wireless device connecting to a WiFi network. There are three primary WiFi bands: 2.4 GHz, 5 GHz, and 6 GHz. Each of these bands has specific characteristic that determine the way that each band travels through walls and other obstacles, as well as how that band may experience interference from other devices use that band.
The 2.4 GHz band uses longer waves, allowing the 2.4 GHz band to travel through walls more effective than the higher frequency bands. Additionally, because the 2.4 GHz band has a longer range, it can reach smart home devices that are located further from the router. However, many device use the 2.4 GHz band, causing interference.
Which WiFi Band to Use: 2.4 GHz, 5 GHz or 6 GHz
Devices like microwaves, Bluetooth devices, and baby monitors all use the 2.4 GHz band, making it less reliable. The 5 GHz band offer higher speeds than the 2.4 GHz band but has a shorter range. It can carry more data and people use it for stream content from various platforms.
However, 5 GHz signals do not travel as effective through walls as the 2.4 GHz band. If a device is too far from the router, the signal will weaken. 5 GHz bands are best for devices close to the router, while the 2.4 GHz band are used for devices located further from the router.
The 6 GHz band, used with WiFi 6E technology, offers even more higher speeds and less interference than the 5 GHz band. There are more available channel within the 6 GHz band, which reduces the instances of networks competing for the same amount of data, reducing signal congestion. Additionally, the 6 GHz band is ideal for tasks that require low latency, such as video call.
However, the 6 GHz band has a very short range. Therefore, you will need to ensure that your devices using the 6 GHz band remains close to your router to maintain a stable connection. Interference is another problem with WiFi bands.
Interference occur when many devices in the same area use the same WiFi frequency. To avoid interference, you must choose the correct band for your devices. For devices such as smart lights and smart locks, you should use the 2.4 GHz band as these devices do not require high speed but require a long range.
For devices such as televisions and gaming consoles, you should use the 5 GHz band as these devices require higher speeds to perform there functions effective. Distance is another major factor to consider when using WiFi bands. As the distance between your device and your router increase, the signal strength of your WiFi bands decreases.
The decrease in signal strength is more noticeable on the 5 GHz and 6 GHz bands than the 2.4 GHz band. If you have a large home, you may want to invest in a mesh WiFi system that will extend the range of your WiFi bands to cover the entire home. Finally, the last factor to consider when choosing your WiFi hardware is the number of devices in your home and the layout of your home.
If you have a small home with a few devices, a dual band router will serve you well. However, if you have many device, you may want to consider purchasing a tri-band router. Additionally, if you would like your WiFi to accommodate future technologies in your home, purchasing WiFi 6E router hardware will allow your devices to utilize the 6 GHz band.
However, you must make sure that the device in your home support the 6 GHz band.
