Difference Between 2.4GHz and 5GHz Wireless

What's the Difference - 2.4 GHZ VS 5 GHZ?

Wireless devices and technology for industrial applications have been a key factor in the success of the Industrial Internet of Things (IIoT). The rapidly deployable wifi connection technology, including 5GHz WiFi range, has given companies the ability to extend networking communications in areas where traditional wiring may be too expensive or not possible due to solid objects in the way. This has allowed for the introduction of new types of technology. This combination has led to increased productivity and expanded services in a safer, more efficient manner. However, there are some also wondering what does 2.4 GHz mean? Continue reading to understand 5G vs 2.4G Wifi speed and how network congestion can interfere with bandwidth and radio waves.

 

Primary Wi-Fi Signals

The IEEE 802.11 wireless communication standards we use today for industrial wireless routers have three different frequencies or bandwidths - 2.4GHz, 5Ghz, and in the near future 6Ghz WiFi frequencies. It is a good idea to have a basic understanding of how these frequencies operate on a wireless router to ensure you get the most out of your enterprise or operational wireless network, including 5GHz channel selection. When comparing 2G vs 5G, it's important to note that a 5GHz access point can reduce network congestion and improve performance, particularly in environments with a lot of wireless internet activity. Additionally, understanding how fast 5G WiFi is and the differences between an access point 5GHz and a wireless access point 5GHz with 802.11 b/g/n 5GHz capabilities can help optimize your network. Using the same frequency for multiple devices can cause interference, so managing the 2.4 radio and 5 GHz channels effectively is crucial for maintaining a robust wireless network.

 

Wireless Basics

All wireless communications operate using channels to transmit and receive data for seamless connectivity. These channels have a specified width (measured in megahertz) which determine the speed data can be sent and received. Sometimes the fewer devices connected to certain channels can mean faster speeds. Keep in mind, the width of these channels can be aggregated to increase speed and throughput of the data. However, by aggregating channel width you will reduce the channels available for use.

 

Wireless bandwidth is partly dependent on channel width and frequency. As a rule of thumb, the higher the frequency, the wider the channel, the faster your bandwidth speeds will be.

 

Characteristics of a Wireless Wave

2.4GHz, 5GHz, and 6GHz are wireless frequencies based on electromagnetic spectrum wavelengths. Each wavelength has its own characteristics for each frequency. The 5GHz wavelength is shorter, making it ideal for high-speed applications in open areas where obstructions are limited, thus providing an extended 5GHz WiFi range.

 

Difference Between 2.4GHz and 5GHz WIFI

Let's discuss the difference between 2.4 G vs 5G WIFI because many question ‘what is 2.4G Wifi’? The 2.4GHz wireless spectrum consists of 14 channels, however, not all channels are available for use. Different countries have different regulation bodies that control which channels can be used. In North America, the FCC regulation permits the use of only channels 1 - 11, while channels 12 - 14 are not permitted.

 

The 11 available channels are 20MHz wide with a 5MHz of spacing between them. The 5MHz spacing causes channel overlapping which leads to poor connectivity and undesirable results. For these reasons, in North America, it is considered a best practice method to only use channels 1,6,and 11 - the three non-overlapping channels. You can arrogate 2 x 20Mhz channels into 1 x 40Mhz channel for increased throughput, but this option restricts channel availability and is not recommended.

 

2.4Ghz supports IEEE 802.11b /g /n networking protocols. Each of these protocols use 20MHz channels, with the exception of 802.11n which can be used for both 20 and 40MHz channels.

 

The 5GHz wifi channels spectrum uses 24 non-overlapping channels divided in four different sections UNII-1, UNII-2, UNII-2 extended, UNII-3, and ISM. Each section has its own recommended uses and restrictions. Each channel is also 20Mhz wide with 20MHz of space separating the channels.

 

The best WiFi settings for 2.4Ghz and 5Ghz WiFi access points will depend on the amount of interference in your area. To find the best channel for your network, you can use a WiFi analyzer tool to check which channels are less congested in your area.

 

Want to know what frequency is 5G Wifi? In general, 36, 40, 44, and 48 are the best 5G channels WiFi because they are least likely to overlap with other channels. However, if these channels are already congested in your area, you can try using channels 149, 153, 157, and 161 as they are also less likely to overlap with other channels.

 

5 GHz wifi uses a variety of channel widths allowing 20MHz, 40MHz, 80MHz, and 160MHz, unlike 2.4GHz which allows for only two channels’ widths (20Mhz and 40Mhz). The 5 GHz wifi channels also supports the IEEE 802.11a /n /ac networking protocols. The higher frequency combined with ultrawide channel width plus the latest 802.11ac standard makes 5GHz wifi channels best for high-speed wireless networking.

 

However, there is a downside to the 5GHz spectrum. The higher frequency also means it is less susceptible to obstacles and has a shorter distance span between the transmitter and receiver.

 

BEST WIFI SETTINGS 5GHZ AND 2.4GHZ

The best WiFi settings for 5GHz and 2.4GHz will depend on several factors, including the type of wireless router you have and its devices connected. Here are some general guidelines to help you optimize your 2.4GHz and 5GHz WiFi network:

 

Choose the right channel: Select a channel that is less congested and has fewer competing signals. This will help improve your WiFi performance.

 

Choose the right bandwidth: If your dual band router supports it, select the 80 MHz bandwidth for better performance. However, if you have a lot of devices connected to your network, it may be better to use the 40 MHz bandwidth to reduce congestion.

 

Use WPA3 encryption: WPA3 is the latest WiFi encryption standard and provides better security than WPA2. If your dual band router supports WPA3, use it for improved security.

 

Position your router properly: Place your dual band router in a central location, away from walls, metal objects, and other devices that can interfere with the WiFi signal. This will help ensure that your devices can receive the best possible signal.

 

Is 2.4GHz or 5GHz Wireless Better?

Are you contemplating WiFi 2.4G vs 5G? You’ll be happy to know that applications that require higher bandwidth speeds should take advantage of the 5GHz wireless spectrum. 2.4GHz falls short of the speeds that 5GHz channel wifi offers. However, if you require connectivity between two points at longer distances and speed is not an issue, or if you have legacy equipment that requires wireless connectivity or have large obstacles in between your transmitter and receiver then 2.4GHz would be your best choice.
