Difference between 2.4 GHz and 5 GHz WiFi network
If you want or have purchased a wireless router, be sure to read the 2.4 GHz or 5 GHz network specifications on the sales box. In fact, what does that mean? If you want to know, you might want to say that a 5GHz modem has a faster connection speed. If you know the difference between a 2.4 GHz network connection and a 5 GHz network connection, which one is faster?
Table of differences between 2.4 GHz and 5 GHz WiFi networks
To make things easier, it’s a good idea to look at the differences in the table below. Once you have read it, you will understand immediately!
Differences between Wi-Fi networks
Wider signal range coverage; best for penetrating solid objects
Faster connection; no interference up to 2.4 GHz; In general, few use this frequency.
Not too tight; many distractions; normally more devices use this frequency
Small signal area coverage; not so good at penetrating solid objects
Maximum connection speed supported
Up to 150Mbps
Up to 1Gbps
Maximum router signal coverage
about 125 meters
Less than 125 meters
Well, in the table above you can already see the difference between 2.4GHz and 5GHz networks. Below, we explain the differences in detail.
1. Comparison of 2.4 GHz and 5 GHz WLAN: network frequency range
One of the differences between the 2.4 GHz and 5 GHz frequencies is the distance between them. Networks on the 2.4 GHz frequency can achieve longer connection distances than networks on a 5 GHz frequency. This is due to the fundamental properties of waves, which are attenuated faster at higher frequencies. So if you want to use the network connection for longer distances between devices, you can choose the 2.4 GHz frequency instead of 5 GHz.
2. Comparison of 2.4 GHz WLAN and 5.0 GHz WLAN: data transmission speed (bandwidth)
How does this affect the WiFi network? If your network bandwidth is higher, it means you can upload and download data faster. Also, you can enjoy streaming video faster and smoother.
Using a network with a higher frequency allows faster data transfer, so in this case, using a network with a 5 GHz frequency will provide a much faster data connection than the 2 GHz frequency. .4GHz
From the table above we can also see that 2.4GHz frequency only supports data speeds up to 150Mbps. Meanwhile, 5.0GHz supports data speeds up to 1Gbps.
One thing you need to keep in mind is that the data speed your WiFi router can transmit always depends on the ISP you use. For example, if you are using an ISP with 170 Mbps Internet, you will still get speeds of up to 150 Mbps on the 2.4 GHz frequency. If you use the 5.0 GHz frequency, you will get Internet speeds of up to 170 Mbit/s (remember that the support limit for the 5.0 GHz frequency is 1 Gbit/s).
So even if you use the 5.0 GHz frequency, you won’t necessarily get 1 Gbps speeds. It still depends on the ISP.
3. Comparison of 2.4 GHz and 5.0 GHz Wi-Fi: Interference with wireless network devices
What are you talking about? Using devices with WiFi connectivity will result in different wave interference. Most devices use the 2.4 GHz network frequency, such as microwave ovens and cordless phones. More and more devices using the same frequency can increase interference with other devices. This may cause the speed of the wireless network used to decrease.
Therefore, it is better to use 5GHz frequency network to avoid being affected by 2.4GHz frequency interference. In short, 5GHz network is more exclusive than 2.4GHz network.
4. Comparison of 2.4 GHz and 5.0 GHz Wi-Fi: device compatibility with network frequency
Can all devices be connected to different frequencies? Unfortunately no, as mentioned the 5 GHz frequency can be considered more exclusive than 2.4 GHz devices.
If you are using a laptop to be able to connect to a WiFi network with 5GHz frequency, your laptop may not support the same network frequency, so WiFi cannot be used. On the other hand, devices with a 5 GHz frequency can still connect to a 2.4 GHz network frequency.
So choose 2.4GHz or 5.0GHz WiFi frequency?
It all depends on the needs and also on the device support. Currently, many WiFi routers support two frequencies at the same time, namely 2.4 GHz and 5.0 GHz. This means that the router can transmit the Internet on two frequencies at the same time.
The average mobile phones, laptops and tablets in circulation must support WLAN with a frequency of 2.4 GHz. Of course, if your device only supports one frequency, you should only surf on that frequency.
There are also devices that support both frequencies. Now when that happens, choose which frequency you want to use. If you want to use the Internet via WiFi in a position far away from the router, just choose 2.4GHz as it has better signal strength. Therefore, the Internet speed is not as fast as 5.0 GHz.
If you are using a device near a router and need high speed, just use the 5.0 GHz frequency.
Now you know the difference, right?
