Wireless WiFi networks work in our homes with a technology that many times we are unaware of and we don’t understand why we have two SSID names on our router. Nor do we know why one signal works with a higher navigation speed than another, one reaching further than the other.
This is due to the frequency with which the router devices broadcast the signal, which are 2.4 GHz and 5 GHz. Each of them have different benefits that can be used in particular situations, for example, the distance between the router and the device will be an issue to consider when choosing one.
So that you know how you can improve the navigation of WifiPay attention to this post because we will show you all the information you need about this technology. We will also explain the maximum speeds you can achieve with each frequency.
What is 2.4 GHz WiFi and what are its main features?
The frequency 2.4 GHz that a router uses is a path that has “13 + 1” channels (dedicated, the latter, for the central frequency) to send and receive the requested information between the connected devices and the router. Navigation speeds are usually in the order of 50 to 65 Mbps.
These channels can be shared by nearby networks. That is, it is characterized by having a longer signal range since it can reach up to 50 meters from the device that emits it. But this will depend on the materials surrounding the radio waves, since there are several that repel it, while others absorb them, generating interferences of a greater or lesser degree.
From the previous paragraphs we can get that, the bandwidth of this frequency is limited since many times they are saturated more frequently, due to the large amount of data that travels in narrower channels.
Being wireless, it is easier for intruders to intercept the signal waves, because anyone with a WiFi interface controller can access it. To avoid being attacked, current technology has developed different methods that allow strengthening wireless networks, such as WPA2 security protocols.
What is 5 GHz WiFi and what are its main features?
Unlike the 2.4 GHz frequency, the signal is emitted through 5 GHz by a router, it has a much higher bandwidth, since it has 25 channels to make information travel. Your speed up 865 Mbps allows you to navigate more comfortably.
In this way, with 5 GHz the navigation does not collapse and has a higher speed for the user much higher than the old frequency. This is because the interference is less, according to the design that this radio wavelength presents and at the same time is less used by users.
This technology is limited by the range of its signal. Since it can reach a maximum of 30 meters, depending on the router. It is ideal for equipment that can be moved or requires a higher navigation speed. For example, a mobile phone, a laptop or the smart TV in the room, if it is near the router and you want to see streaming content in 4K. It is also easy to hack, as is the 2.4 GHz.
Advantages and disadvantages of using a 2.4GHz frequency in your Wi-Fi
One of the most important advantages of this 2.4 GHz frequency is that, being an older technology, is supported by all devices that have the ability to receive a wireless signal. This is because it uses the IEEE 802.11b, 802.11g and 802.11n standards.
We can also mention as a positive feature that, has a much greater network range, so the scope is wider in external spaces. But in return we can say that suffer greater interference. This is because, as there are a larger number of objects that can absorb radio frequency waves, the signal does not arrive in the best way.
By having few channels, these saturate faster. This is generated because the users are more than those of other frequencies, causing the speed to be lower for navigation. In addition, it reaches a speed of no more than 65 megabits per second. This technology is used for equipment that is remote from the router or is older than that of new equipment.
Advantages and disadvantages of using a 5GHz frequency on your WiFi
In order to use this frequency, it is necessary to have a special router that must have dual band, so those older routers are discarded. Although this in principle would be a disadvantage, in reality we can also take it as a plus. Because new equipment is needed, which is much more efficient, to access a frequency of 5 GHz.
It has 25 channels of bandwidth generating a higher speed in navigation. In this way, more users can enter at the same time to send and receive data to the router. This will not cause channels to crash as quickly, because there are not many people who use this signal. The speed it can reach is a little lower than 900 Mbps, so it is suitable for any fiber optic rate that exists in our country.
The interference suffered by equipment connected to this frequency is minor, due to the limited scope of this technology.
2.4GHz Wi-Fi vs 5GHz Wi-Fi, which is better and how are they different?
To define the best frequency, it is necessary to establish some priorities. Since if you are looking for a higher speed in navigation, you need to be connected to a frequency of 5 GHz. Which is ideal for online games or streaming content the highest image quality.
Instead, if what is prioritized is the location of the signal receiving device, it will be important to verify the 2.4 GHz frequency range. This is due to the much longer signal waves that allow for greater coverage. But you must take into account in these cases that the interference will be greater.
By having a greater range, it allows several nearby users to enter the same channels, so these are saturated causing the speed of a 2.4 GHz frequency is up to 65 Mbps. In return, you can enjoy up to 865 Mbps with its 25 channels if you connect to a 5 GHz network.
Another issue you should consider is analyzing the age of your devices. To choose the newest frequency you will need more modern equipment. This will generate a slightly higher investment expense and if you choose the 2.4 GHz technology. This is due to the standards used by the 2.4 GHz frequency (802.11b, 802.11g and 802.11n), while the 5 GHz 802.11a , 802.11n and 802.11ac.
To conclude, we can say that if you receive a 5 GHz signal, do not hesitate and connect at this frequency. This is because you will have a higher speed and will have the least amount of interference possible.
So what is the best WiFi with maximum speed that I should choose according to my needs?
According to the needs you have you will need to choose a Wifi depending on where your device is located relative to the router. That is to say, if you are nearby, you will always have to choose a frequency of 5 GHz. While if you are far from the router you will not have a signal of this last frequency, so you will have to connect to 2.4 GHz.
