About 5 GHz Wi-Fi

In today's digital age, we highly rely on wireless internet connections for all fields of life. This wireless transmission of the internet is possible due to the Wi-Fi technology. When we dive deeper into the technicalities of Wi-Fi technology, there are different bands, like 2.4 GHz and 5 GHz, that have coverage, speed, and range difference. 5 GHZ Wi-Fi is relatively new in the market and in this article, we will explore all you need to know about it.

What is 5 GHz Wi-Fi?

5GHz Wi-Fi is a standard Wi-Fi networking technology that provides a 5ghgahertz frequency band. If we compare 5 GHz Wi-Fi with the traditional 2.4 GHz, there will be more non-overlapping channels available. So, 5 GHZ Wi-Fi reduces interference from other networks and wireless devices. Another benefit is that it provides faster data transfer rates. While the speed of 5 GHz Wi-Fi depends on the router available and its settings, in the best case 5GHz can support up to 1300Mbps speed.

An important thing about Wi-Fi is its range and when we consider the 5 GHZ Wi-Fi the range gets shorter due to high frequency. This range gets even shorter when it gets obstructed by obstacles like walls. The range also depends on the router and its technology. In the best case when there are no obstacles like walls, 5 GHz Wi-Fi may provide a range of 410ft.

With such qualities 5 GHz Wi-Fi with less range and high speed makes a good choice for bandwidth-intensive activities. It is great for streaming content, playing high-definition videos, playing online games, transferring large files, etc.

Pros and Cons of 5 GHz Wi-Fi

5 GHz Wi-Fi has its benefits and demerits and here is a quick overview of both aspects:

Pros

  • Less open to interface
  • High rate of data transfer
  • Less traffic usually

Cons

  • Bad at penetrating solid objects like walls
  • Covers a small area (other than 802.11ac)

Best Channel for 5 GHz Wi-Fi

Optimal performance channel

Choosing the right channel for your 5 GHz Wi-Fi is important to improve its performance. Since 5 GHz has more channels than 2.4 GHz Wi-Fi, you may select the right one to reduce congestion and interference. The best channels for 5 GHz Wi-Fi include:

  • 36
  • 40
  • 44
  • 48

These channels are less likely to be used by other devices so you may get optimal performance.

Alternative channel

If you are in an area where the lower channels are crowded, then you may pick some alternative channels which include:

  • 149
  • 153
  • 157
  • 161

These are even less likely to be used by other devices.

Channel Width

5GHz Wi-Fi supports a wide range of channel widths including:

  • 20 MHz
  • 40 MHz
  • 80 MHz
  • 160 MHz

This way, users can enjoy faster speeds and higher throughput by selecting the wider channel width. 80 MHz is usually a popular choice among people for optimal performance and the best experience.

5 GHz vs 2.4 GHz Wi-Fi: What's the Difference?

2.4 and 5 GHz Wi-Fi bands come with some crucial differences between them that can impact the usage experience and applications like the following:

Frequency

2.4 GHz comes with a lower frequency range than 5 GHz, but it is also more prone to interference from other wireless devices having Bluetooth or microwave signals. 5GHz has a higher frequency range, making it immune to interferences, but it comes at the cost of less range.

Range

2.4 GHz Wi-Fi signals provide better range even when there are obstacles in the way. Meanwhile, 5 GHz already has less range and whenever there is an obstacle like a wall, the range further decreases.

Speed

5 GHz is better at offering high speeds for quick data transfers as compared to 2.4 GHz's lower data transfer speeds.

Channel overlap

2.4 GHz Wi-Fi comes with 3 non-overlapping channels while 5 GHz comes with 23 non-overlapping channels. Hence, the risk of interference in the wireless signals is much less with 5 GHz signals.
Here is a quick comparison table between the two.

Feature 2.4 GHz 5 GHZ
Frequency Lower Higher
Range Longer Shorter
Speed Slower Faster
Channel Overlap More with 3 non-overlapping channels Less with 23 non-overlapping channels
Interference More prone Less Prone

When to use 2.4 GHz and 5 GHz Wi-Fi?

2.4 GHz Wi-Fi signals are better for use cases where speed does not matter a lot, but you need to cover a wider range. Web browsing, social media activities, and office tasks make good use of 2.4 GHz Wi-Fi since range is more important than speed here.

5 GHz is a better choice for use cases where you don't need to cover a long distance and you need significant performance and speed figures. It is a better choice for online gaming, video streaming, etc.
