5G vs 2.4G Router Speed Test

5GHz vs 2.4GHz: What is the best WiFi frequency? The answer would depend on your network needs. When designing a WLAN, you might wonder about the best WiFi frequency for your network deployments. This article will help you understand when it is best to use the 2.4 GHz or 5 GHz band frequency to provide a well-performing wireless experience.

5GHz vs 2.4GHz – A Brief Description of the WiFi Frequency

A frequency band is how wireless data is transmitted between devices. These bands are radio waves that transfer the data, and they can be either 2.4 GHz or 5 GHz. The primary differences between the 2.4 and 5GHz bands are the range (coverage) and the bandwidth (speed) that these bands provide. For instance, the 2.4GHz band offers coverage at a longer range, but it transmits data at slower speeds. Instead, the 5GHz band gives less coverage but sends data at faster speeds.

5GHz vs 2.4GHz – How to choose the right WiFi frequency for your business?

Coverage area vs. data rate

The 2.4GHz frequency band covers a larger area and provides a more extended range than the 5GHz band, but with lower data rates. Instead, the 5GHz band provides a smaller coverage area than the 2.4 GHz band but with a higher data rate.

Speed

The GHz range that a wireless device uses does not necessarily determine the maximum speed of the WiFi. The environment in which the network will be set up is what really should be considered.

For instance, the 2.4GHz band usually supports up to 450 Mbps or 600 Mbps, depending on the device type. However, as so many devices use the 2.4GHz band, the resulting congestion can cause discontinued connections and slower speeds.

Instead, the 5GHz band can bear up to 1300 Mbps. It tends to be less overcrowded than the 2.4GHz band because fewer devices use it and because it has more channels for devices to use than the 2.4GHz. The maximum speed would depend on the wireless standard the access point supports, i.e., 802.11b, 802.11g, 802.11n, or 802.11ac.

When comparing the 2.4GHz band with the 5GHz band, the latter provides lower coverage. Thus, when the frequency increases, its ability to penetrate solid objects (like walls) decreases. This is the reason why the 5GHz band was used mostly in outdoor deployments at the beginning. But at the same time, the higher the frequency, the faster the data is transmitted. Therefore, the 5GHz band carries more data and sends it faster. Then, if your priority is to provide excellent WiFi speed performance, your choice should lean towards the 5GHz band, instead.

Interference

The other thing to check for is potential interference with the WiFi network’s frequency range. Interference can slow down a network significantly and reduce its scope as well. For instance, in the 2.4GHz band, the two most obvious sources of wireless network interference are wireless telephones and microwave ovens. Instead, in the 5GHz band, cordless phones, radars, digital satellites, and perimeter sensors are the most common sources of interference.

When multiple devices operate at the same frequency, there is usually interference that can affect the signal’s characteristics at the receiving point and reduce the connection speed. Your WiFi connection on a particular frequency band can also be faster or slower because of other devices’ interference.

The waves used by the 2.4GHz band are better suited for longer ranges and transmission through walls and solid objects. Therefore, 2.4GHz is more convenient if you need to provide a better scope on your devices or have many walls or other objects where you need coverage.

On the other hand, the 5GHz band’s shorter waves make it less capable of going through walls and solid objects. This happens because of electromagnetic waves’ peculiar characteristics: at higher frequencies (5GHz), waves attenuate more strongly. Hence, the signal is easily influenced by multiple obstacles like walls, floors, ceilings, doors, and others. Overall, the

5GHz WiFi frequency experiences fewer interferences from other devices than WiFi connections using 2.4GHz. Therefore, if your WiFi network is located where there is a lot of interference from other devices and appliances, it will slow down your connection. Therefore, we would suggest steering your devices to the 5GHz WiFi frequency. But, if you want to deliver more signal coverage, then use the 2.4 GHz frequency instead.

As a side note, when using the 5GHz frequency band, the client device (smartphone, tablet, laptop, or USB adapter) must support this frequency.

Congestion

When multiple devices attempt to use the same radio space, overcrowding happens. A negative connotation of the 2.4GHz band is its significant congestion, driven by the high use of this band not only for WiFi but also for other devices like garage door openers, microwave ovens, cordless phones, and Bluetooth devices.

On the other hand, the 5GHz band is not so overcrowded, and it has more free radio air and channels, i.e., 23 working channels vs. 11 in the 2.4GHz band. Consider that channel availability depends on the country in which the deployment is located, which results in higher stability and connection speed.

Cost

Finally, you should be aware that the cost of access points supporting 5GHz is higher than supporting 2.4GHz. This is because 5GHz is newer in the market. Furthermore, many 5GHz devices also support 2.4GHz radios.

A solution for the 2.4GHz and 5GHz WiFi frequencies

 

As previously said, nowadays, most modern access points support single, dual, or even triple bands. Our Tanaza Powered Devices are dual-band, which means that the access point can broadcast both 2.4 GHz and 5 GHz frequencies at the same time, essentially providing you with two WiFi networks and the best of both signals.

The Tanaza Powered Devices with dual-band can be:

• Selectable dual-band. A selectable dual-band device offers a 2.4 GHz and 5 GHz WiFi network, but you can only use one at a time. With Tanaza, you can "tell" the access point which band it should use.
• Simultaneous dual-band A simultaneous dual-band device broadcasts separate 2.4 GHz and 5 GHz frequencies at the same time, giving you two frequencies that you can choose from when doing the network setup. With Tanaza, you can also assign the same SSID to both bands, so the access point only sees a single network, even though both bands are operating. The advantage of having both bands running simultaneously usually outweighs the cost difference.

Lastly, the tri-band access points broadcast three networks simultaneously—two 5 GHz signals and one 2.4 GHz signal. The reason for this is to avoid network congestion. If you have multiple devices that use a 5 GHz connection heavily, you might benefit from spending a bit more on a tri-band device.
