5 GHz vs. 2.4 GHz: which is the better frequency band?

Frequency bands are commonly used in data transmission between devices. Data transmission from one device to another is based on waves operating at 2.4 GHz and 5 GHz frequencies, respectively.

Since the 2.4 GHz and 5 GHz frequency bands are widely used, all wireless devices use them. Wi Fi routers that transmit data in the 2.4 GHz and 5 GHz frequency bands are known as dual-band Wi Fi routers, which are models compared to those that are limited to using only the 2.4 GHz band.

Today, wireless routers mainly use the 2.4 GHz and 5 GHz frequency bands. You may have encountered these bands when configuring or adjusting the operating frequency of your router.

While all of these frequency bands can be used for signal transmission, choosing between them can be challenging due to their differences. Ultimately, personal preference plays a role in determining the optimal frequency range.

Having the option for customers to choose the frequency according to their circumstances is excellent because it is clear that each frequency band has a purpose.

2.4 GHz frequency band

The 2.4 GHz frequency range is widely used in consumer electronics, such as Bluetooth devices, wireless cameras, microwave ovens and other common household items. Although data transfer speeds may be slightly slower in the 2.4 GHz band, its main advantage is that it allows information to be transmitted over distances despite operating at 2.4 gigahertz.

If you prefer a larger coverage area. No matter the data transfer rates, opt for a lower frequency. On the other hand, if your priority is faster data transfer. You don’t need a wide range, choose a higher frequency.

Consequently, the 2.4 GHz frequency range is ideal for long distance connections; however, this comes with the disadvantage of transmission speeds. In addition, because wireless and electrical devices use the same 2.4 GHz band, your WiFi network may occasionally experience signal interference that can slow down or even completely disrupt its operation.

The 2.4 GHz band consists of 11 channels, three of which overlap each other. As a result, three overlapping channels are available, within the reduced spectrum of the 2.4 GHz frequency range.

5 GHz frequency band

Devices do not typically use the 5 GHz frequency band. It is not the default option. As mentioned above, transferring data at this frequency increases the transfer rate. Consequently, the 5 GHz band allows data transfers compared to the 2.4 GHz band, but has a shorter range and has difficulties in penetrating solid objects.

As a result, while you may enjoy speeds at one end of the spectrum, your coverage will be reduced at the other end. The advantage of using the 5 GHz frequency is that there will be no interference from devices, as it offers 25 non-overlapping channels. Therefore, Internet speeds in the 5 GHz range will be significantly faster than those in the 2.4 GHz band. However, due to its nature, this range has limitations in terms of coverage and may encounter obstacles when penetrating solid objects.

Which band is better?

To answer your question, it is important to consider the details of your situation. If your WiFi router is nearby, it is recommended to use the 5 GHz frequency band, as it offers interference, faster data transfer speed and no range limitations.

On the other hand, if your WiFi network is remote, opting for the 5 GHz frequency band would not be efficient, as it can lead to weak signals and frequent disconnections. In some cases it is recommended to use the 2.4 GHz frequency band for long distance communications. This band has a range of 5 GHz and its lower frequency allows signals to pass through solid objects more easily.
