When it comes to WiFi, you may have come across terms like 2.4GHz and 5GHz, which refer to different frequencies that WiFi networks operate on. These frequencies represent two different WiFi standards, each with its own set of advantages and limitations. In this article, we will explore what 2.4GHz and 5GHz WiFi are and delve into the differences between these two WiFi standards.
The 2.4GHz and 5GHz WiFi bands are network devices that make WiFi signal reception faster and easier, bringing many benefits to users. Join Thptlaihoa.edu.vn to find out what 2.4GHz and 5GHz WiFi is and some of the differences between the two WiFi standards!
What is 2.4GHz WiFi standard?
Standard WiFi 2.4GHz , also known as 2.4GHz band, is known as a WiFi channel that provides signal transmission frequency range up to 2.4GHz . Currently, some technologies use WiFi standard 2.4GHz such as Bluetooth wave, microwave wave, TV signal.
Sometimes, devices with the same 2.4GHz standard band will interfere with each other, resulting in data transmission speeds not reaching 2.4GHz . The 2.4GHz WiFi band supports the highest speed of 450Mbps or 600Mbps , depending on the router you use.
What is 5GHz WiFi?
5GHz standard WiFi, also known as 5GHz standard band, is a WiFi channel that broadcasts with frequency bands with signals up to 5GHz. In particular, when using the 5GHz standard band, it is less common to see the same frequency as 2.4GHz WiFi.
However, the signal transmission distance is not fast and more easily obstructed than standard 2.4GHz WiFi. The connection speed of 5GHz WiFi standard is up to 1300Mbps in ideal environment.
Compare 2.4GHz and 5GHz WiFi
Speed/Bandwidth
If we compare the speed and bandwidth of 2.4GHz and 5GHz WiFi on the scale, we can see that in ideal conditions, the network speed of 5GHz WiFi can be up to 1300Mbps, which is quite impressive speed compared to WiFi. 2.4GHz with speeds from 450 – 600Mbps.
Thereby, 5GHz WiFi has faster file download speed, faster opening web pages, especially you can play online games without having to worry about the network.
Connection range
According to the principle of radio wave propagation, the higher the frequency, the higher the signal loss over the distance. Due to 5GHz WiFi bandwidth works with high band. Therefore, 5GHz WiFi operates in high frequency band, so the connection range is not as wide as 2.4GHz WiFi.
Interference ability
These two streams of bandwidth are not penetrated by other devices. For 2.4GHz WiFi, devices such as: Bluetooth speakers, Bluetooth headsets, … use electromagnetic waves that can interfere with the device, causing the network speed to be reduced.
WiFi 5GHz has the feature of not being affected by wireless devices, so it helps WiFi to work more stable.
Possibility of congestion
The 5GHz WiFi series operates with a wider band than the 2.4GHz WiFi, so users are more secure when congested when there are many devices accessing the network at the same time. This means you will always have a stable network connection, ensuring smooth operations.
Price
2.4GHz WiFi is quite suitable for the needs of users, the price ranges from 200,000 – 1,500,000 VND. The price of 5GHz WiFi is diverse, ranging from 400,000 to 15,500,000 VND (Price updated in November 2022). With this price, users have more options with more outstanding features such as integrating both WiFi waves on the same set.
2.4GHz and 5GHz WiFi comparison table
Criteria | WiFi 2.4GHz | WiFi 5GHz |
Speed | 450-600Mbps | 1300Mbps |
Standard operating frequency | 802.11b | 802.11a |
Bandwidth | Lower than WiFi 5GHz | Higher than WiFi 2.4GHz |
Transmission range | Distant | Short |
Ability to penetrate solid objects | Good | Least |
Should choose WiFi 2.4GHz or 5GHz
You should choose to buy 2.4GHz WiFi when your work environment has many obstacles and you want WiFi to have wider coverage. Besides, 2.4GHz WiFi can fully meet the requirements of web browsing, basic social networking.
You should choose to buy 5GHz WiFi when used to play online games smoothly, with low latency, watch full movies online Full HD, high quality 4K, especially when you want to use the network to exchange heavy data. However, 5GHz WiFi has a rather narrow coverage, to improve this situation you need to broadcast 2 parallel frequencies of 2.4GHz and 5GHz.
So Thptlaihoa.edu.vn shared with you what 2.4GHz and 5GHz WiFi is and the difference between the two WiFi standards. If you have any questions, don’t hesitate to leave a comment below for a quick response!
In conclusion, 2.4GHz and 5GHz WiFi are two commonly used wireless networking standards. The key difference between these two standards lies in their respective frequencies, with 2.4GHz operating at a lower frequency and 5GHz operating at a higher frequency.
While 2.4GHz has been widely used for many years due to its longer range and ability to penetrate walls and obstacles more easily, it suffers from a higher chance of interference from other devices using the same frequency band. On the other hand, 5GHz offers faster data transfer speeds, lower interference, and better performance in areas with higher network congestion. However, it has a shorter range and is more susceptible to signal degradation when obstructed by walls or other barriers.
The choice between 2.4GHz and 5GHz WiFi depends on the specific requirements and limitations of each user. For those looking for wider coverage and compatibility with older devices, 2.4GHz may be the preferred choice. On the contrary, individuals seeking higher speeds and better performance in densely populated areas would benefit from utilizing the 5GHz frequency.
Ultimately, it is important to consider the specific needs and limitations of your WiFi usage to determine which standard is most suitable for your environment and devices. With the continued advancement of technology, WiFi standards may change and evolve, offering even greater capabilities and differentiating features in the future.
