2.4GHz vs 5 GHz, What’s a Difference, Which is Better? Which Should I Use?

Using frequencies, your wireless router transmits the Internet to WiFi connected devices such as cellphones, digital computers, tablets, and other gadgets. Most current wireless routers have two separate bands of channels, i.e., 2.4 vs. 5 GHz.

But picking one between these is tricky, especially if you’re not a geek and want to plug everything in and go online.

Today, I will tell you the significant differences between 2.4 GHz and 5 GHz WiFi. And most importantly, helping you choose the one which fits your needs the most.

What is the ideal WiFi frequency: 5GHz or 2.4GHz?

While designing a WLAN, you might wonder what the ideal WiFi frequency is for your computer network installations. This article will explain when it’s preferable to use the 2.4 GHz or 5 GHz band frequency to get the best wireless performance.

A frequency band is used to send and receive wireless data between devices. These bands are data-transmitting radio waves with 2.4 GHz or 5 GHz frequencies.

The range (coverage) and bandwidth (speed) provided by each 2.4 and 5GHz band are different. The 2.4GHz band, for example, has a more extensive range of coverage but sends data at a slower rate. The 5GHz band, on the other hand, has less coverage but transfers data at a higher rate.

What are 2.4 and 5GHz WiFi Routers?

Since the creation of WiFi, there has been a slew of new wifi standards aimed at improving both wifi speed and coverage. For instance, the Wifi standard 802.11n (also named wifi 4) was announced in 2009, and it was the first to support both the 2.4 GHz and 5 GHz wifi frequency bands. So,

2.4GHz Band

A 2.4 GHz frequency wireless band router allows the Internet to be used across more considerable distances. It lacks in speed what it makes up for in distance.

Streaming videos and downloading large files takes much longer on the 2.4 GHz wireless band. Because such devices are far distant from their routers.

5GHz Band

Usually, a 5 GHz wireless band is employed when speed is more crucial than distance. Your web pages will be streamed very high speed using the 5 GHz frequency. This is the most common frequency for personal and office use.

Professionals need their data to load quickly and large files to download rapidly to get their work done. People download big files and stream their favourite shows at home.

Note: Nowadays, most routers have switched from single to dual-band mode, allowing them to use wireless signals over either of the two WiFi frequency bands.

2.4GHz vs 5GHz routers, which one to Choose? (Considering 8 Points)

Now I compare both the 2.4 and 5 GHz bands in the following factors and ascertain the differences precisely. And thereafter a chart of summary between 2.4 vs 5 GHz.

Range

2.4ghz vs 5ghz, which has more range and coverage of network

In terms of WiFi range, 2.4 GHz outperforms 5 GHz because lower frequencies are sent in the 2.4 GHz band, enabling to penetrate solid objects, allowing the signal to go further throughout your home.

Thus, 2.4GHz WiFi has a broader range than 5GHz WiFi, making it perfect for areas where the signal has to reach a wider area, such as large retail stores, pubs with many floors, and hotels with a pool area. Those using the 5GHz frequency, on the other hand, typically cover about one-third of these distances.

Speed

The 5 GHz band compensates for its lesser range by providing significantly better WiFi speed rates than the 2.4 GHz band. In comparison, the 2.4 GHz band will enable up to 600 Mbps, while the 5 GHz frequency will support gigabits up to 1300 Mbps.

The faster data is delivered, the higher the frequency – generally referred to as bandwidth. While 5GHz WiFi may not have the same coverage as 2.4GHz WiFi, it can carry more data and transmit it at a faster rate over a shorter distance.

Solid Object Penetration (Walls, Shelves, Floors)

Higher frequencies bands cannot penetrate solid objects like walls and floors, however lesser frequencies such as 2.4GHz bands tend to be more reliable to provide network crossing solid objects and walls.

Therefore, higher frequencies, such as 5 GHz, allow data to be sent quicker than lesser frequencies, allowing you to upload and download files faster than 2.4 GHz but at the same time, less penetrate to solid objects

Since the 2.4GHz band uses longer waves, making it is more suited for transmission over longer distances or through solid structures like walls. If you connect devices for a low-bandwidth activity like browsing the Internet benefits, you should choose the 2.4GHz frequency instead of the 5 GHz frequency.

Another reason to continue with 2.4 GHz for WiFi networks in vast places with many barriers, such as office floors, is more reliable. There’s a considerable likelihood that 5 GHz signals will drop out if multiple walls exist between a router and a device. As a result, 5 GHz should only be used in single rooms, small households, or fewer objects placed.

Streaming, Gaming, or Videoconferencing

2.4ghz vs 5ghz for gaming, streaming or video conferencing

5GHz is best for high-bandwidth devices or activities such as gaming, videoconferencing, and HDTV streaming. Thus, without a doubt, a 5GHz band surpasses 2.4 GHz in performance for such purposes. But it doesn’t mean that the 2.4 GHz is insufficient; in fact, 2.4GHz works adequately good.

Ideal Users

In places like shops, restaurants, hotels, and coffee shops, even at home, the 2.4 GHz frequency is used, while the 5 GHz band is used mostly for personal and office use or where speed matters the most than range.

Types of Devices used

Almost all household gadgets, including microwaves, ovens, refrigerators, wireless mice, keyboards, digital, laptops, Chromebooks, operate on the 2.4 GHz frequency spectrum. It is also compatible with several older devices. Contrarily the 5 GHz frequency band was introduced later than the 2.4 GHz frequency band; it can only be used with more recent and latest compatible devices.

Number of Connections

A single router can support up to 32 wireless devices on the 2.4 GHz frequency band and another 32 devices on the 5 GHz frequency band, for a total of 64 wireless devices.

Cost

2.4GHz WiFi packages are much less expensive than 5GHz WiFi packages, which are newer on the market and give faster speeds. Today, you have the option of dual-band routers (which come inbuilt of both 2.4Ghz and 5Ghz) that nowadays are used by many people fulfilling both the needs.

Pros and Cons of 2.4 GHz and 5 GHz

Pros of 2.4ghz Cons of 2.4ghz
It is less expensive to numerous gadgets available that utilize this frequency. As a result, this frequency has become the industry standard, and any Wi-Fi-capable device can connect to it.Its bandwidth is less than that of the 5 GHz network.
Its range is significantly greater than that of a 5 GHz wireless network. Radio waves can penetrate solid surfaces (such as walls and floors) far more effectively than 5 GHz radio waves.Wireless routers and devices like cordless phones and microwaves use the same 2.4 GHz radio waves. If you have such gadgets at home, they can interfere with the router’s radio waves, resulting in a reduction in network capacity. Because more devices support this frequency, it is more congested, potentially causing bandwidth concerns.
