Know The Difference Between 2.4 GHz and 5 GHz Wi-Fi?


As explained in this review – the Wi-Fi system we use in our homes or offices operates with two different ‘bandwidth’ namely 2.4 GHz and 5 GHz. The essential difference between these two bands is the speed. In reality, the lower 2.4 GHz supports the devices that operate between 450Mbps and 600 Mbps, while the 5 GHz supports up to 1300 Mbps.

Bandwidth Basics
Before discussing the difference between 2.4 GHz and 5 GHz let us know some basics about bandwidth. Technically the term bandwidth indicates to the bit-rate transfer of information and a bandwidth test reveals the rate and speed at which information may be exchanged or transferred. It is measured in Hertz which is otherwise known as cycles per second.

One can download the freely available software programs to conduct the test and get the speed of the Internet connection. It is more helpful to understand the rate of increased traffic and at different times of the day, especially for companies that have specific working hours. When it comes to a wireless router, there are some standards such as 802.11b, 802.11ac.

The 2.4 GHz
In general, the 2.4 GHz band is known to be well crowded as it supports several applications like cordless phones, baby monitors, garage door openers and many more. These longer waves are primarily for a longer range of transmissions which can even penetrate walls and other solid objects. However, since this band has a wider application, it can create congestion thereby lower the signal strengths and the speed connections.

The 5 GHz
On the other hand, the 5GHz is said to be less congested and can offer a stable connection. However, this higher band with shorter wavelength cannot penetrate the walls and hence reduce the effective range than the 2.4 GHz. In such cases, one can use the range extenders or any other Wifi mesh system though it might need additional investment.

Dual Band Routers
With the advanced technologies, experts have invented dual-band routers so that it can handle both 2.4 GHz as well as the 5 GHz in the same unit. These devices come in two categories namely selectable dual-band and simultaneous dual band. In the former type, one has to select either 2.4 GHz or 5 GHz, and in the latter, one can use both the bands at a time. A tri-band router can also be used wherein there are two 5GHz systems are functional along with a single 2.4 GHz. People who use regular streaming can make use of these tri-band routers.

When it comes to the selection of Wifi and Ethernet wired connection, the latter has many advantages over the former. With the wired connection many issues like slower speed, lower signal strength can be avoided. Also, one has to ensure the device used is compatible for both 2.4 GHz as well as 5GHz which is vital before choosing a high-speed router.
