What devices should I connect on the 2.4 GHz wifi and which in 5GHz

Therefore, to end the network cable connections to those gigabit ethernet ports of our Dual Band router we recommend connecting the following equipment:

1. Los PCs de sobremesa que estén cerca.
2. Un portátil que esté casi siempre en el mismo sitio y tenga cerca el router.
3. Una Smart TV, consolas de juegos y otro tipo de dispositivos multimedia. En bastantes casos, sobre todo cuando está en el centro de la casa y se sitúan al lado del router, es muy recomendable conectar estos equipos vía cable. En ese caso olvidaos del WiFi, ya que el cable de red os va a dar un mejor rendimiento.

Network analysis of 2.4GHz, regulations, advantages and disadvantages

If we want to know which devices it is better to connect to the Wi -Fi 2.4 GHz and which in 5GHz we have to start to meet them.Now we are going to treat the 2 network.4 GHz, through its nomenclature, we will know what speed they can reach.Then we will go to its advantages and disadvantages.

Now is the turn of talking about the 802 standard.11 which is a family of wireless standards created by the Institute of Electrical and Electronic Engineers.In the case of the band of 2.4 GHz, current router work with the 802 standards.11b / g / n / ax.

The oldest is 802 Standard.11b, which was approved in 1999.The maximum speed is 11 Mbps transmission.In real life this maximum speed is reduced approximately 5.9 Mbps on TCP and to 7.1 Mbps on UDP.Next, in June 2003 the 802 standard was approved.11g.In this case we could consider it as its natural evolution.With this mode you can get a maximum theoretical speed of 54 Mbps.On the other hand, the real real transfer average that was obtained was approximately 22.0 Mbps.

The 802 standard.11N was approved in September 2009.In this case, the maximum theoretical speed that can reach depends on the number of Wi-Fi antennas, both internal and external, in real life there are equipment with a total of four Wi-Fi antennas, which are capable of providing a speed of up to up to 1.000Mbps thanks to the modulation of amplitude in quadrature 1024qam.A fact that we must comment is that you can work in the 2.4 GHz band and the 5 GHz simultaneously.This standard is currently called Wi-Fi 4.

Finally, we currently have the 802 standard.11ax, which was approved recently and are already beginning to see routers, wifi access points, wireless network cards and other devices such as smartphones or tablets that support it.I use the same band of 2.4GHz, but improves your performance to provide up to 1.148MBPS When we use four antennas in Mu-Mimo 4T4R configuration.

As for the 2.4 GHz wifi band we can comment that it operates from the 2.412 MHz (Channel 1) to 2.472 MHz (Channel 13).Therefore, we would have a new channel every 5 MHz of separation.In addition, the channel width is 20MHz or 40MHz, so with a pair of Wi-Fi networks we would be occupying almost the entire spectrum available.

As you can see, the inconvenience of having few channels will cause us to have many interference with nearby networks.If you make a simple check with your smartphone of the networks available in a large city, obtain a result of more than 20 would not be strange.

These interference that we suffer with nearby Wi -Fi networks cause 2.4 GHz networks to obtain a connection rate much lower than 5 GHz.In general we could have an average maximum speed of about 60 or 80 Mbps.However, thanks to the fact that the frequency used is lower, we get its greatest advantage and that is none other than its signal further.

Another very important feature of the 2 band.4GHz When we are using the WiFi 6 standard, we have the OFDMA technologies that allows usof connected wireless customers.We also have Mu-Mimo technology, which will allow us.OFDMA AND MU-MIMO complement each other to optimize the Wi-Fi network in 2.4GHz to connect more Wi -Fi customers and to transfer data much faster than the previous standards.In addition, in this frequency band we will also have technologies such as beamforming, a technology that allows us.Of course, we cannot forget one of the benefits of Wi -Fi 6 with the BSS Color, a technology that will allow usminimal possible interference.

In short, 2 networks.4 GHz have less connection speed, but in return, the coverage of their signal comes further than those of the 5 GHz networks.

Analysis of 5 GHz networks, regulations, advantages and disadvantages

The first standard used by the 5GHz band was 802.11A, with a maximum speed of 54mbps, exactly the same as the 802 standard.11g for the 2 band.4GHz.The next standard to use this frequency band was 802.11N, with the same speed and characteristics as the 2 band.4GHz, but it was a before and after since the first simultaneous double band routers began to appear.

In the 5 GHz band we have to talk about the 802 regulations.11AC that was approved in 2014.It is currently the most used in this band.Another way to name it is like wifi 5, wifi gigabit or like wifi 5g.Transfer rates of up to 433 Mbps per data flow can be obtained if we use a 256qam quadrature amplitude modulation.As theoretically maximum speed we could reach 1 rates.3 Gbps using 3 antennas, or 1.7GBPS If we use 4 antennas.In addition, if we use a 1024qam quadrature amplitude modulation, the speed will be 25% higher, around 540MBPS per data flow.

Finally, the 802 standard.11ax that is prepared to operate in the bands of 2.4 GHz and 5 GHz.It is popularly known as wifi 6, I mention it so you can know what the future of our Wi -Fi networks will be.As for the 5 GHz networks there are 21 channels of 20 MHz, having more we will have less possibilities that a network coincides in the same channel, although in this case we have widths of 80mhz or 160mhz channel, so neither does it eitherWe have so many channels available, but clearly many more than in the 2 band.4GHz.The difference between using 80mHz channel width VS 160MHz channel width in the 5GHz band is clear, using twice as much channel width we can gain around an additional real speed, for example, our speed record usingA INTEL AX200 WIFI card is 1125MBPS using 160MHz channel width, and about 800MBPS using 80mHz wide channel.In the case of a Xiaomi Mi 11 ultra smartphone, we have proven that with 160MHz channel width we can get up to 900MBPS real, for the real 850Mbps that we will get if we use 80MHz wide channel.Where we will most notice the double channel width is in nearby-medium places, it is where we can see more between using 80 or 160mHz channel width.

Therefore, we can affirm that the great advantage of 5 GHz networks is that we get a connection speed far higher than those of 2.4 GHz.If we use a modern smartphone that supports 5 GHz networks we can obtain speeds greater than 500 Mbps and even superior if we use a laptop.Instead, 5 GHz networks because of the frequency they use, have an inconvenience and is none other than the distance and obstacles such as the walls.This also has its positive point (having less coverage), since the Wi-Fi networks of the neighbors will be attenuated a lot and will not interfere with ours.

The Wi -Fi Alliance has already standardized the new 6GHz band, which is the perfect complement to the 5GHz band since it will allow us to connect a large number of devices without interference, having even more channels to connect equipment.Thanks to this decision, very soon we will see routers with Wi-Fi 6 using this wi-fi frequency band, the new standard is called WiFi 6E, and it has exactly the same characteristics as Wi-Fi 6 but we can connect to a new frequency bandWi -Fi in 6GHz to have more free channels.

Criteria for choosing which wifi network connect ourselves

Now that we know the virtues and inconveniences of the 2 2 Wi -Fi networks.GHz and 5 GHz we will learn what kind of network each one is doing better.The best thing we can do is study the device and decide based on:

1. La distancia que está del router.
2. El ancho de banda que necesita.

As a general rule we could say that devices that need a lot of bandwidth, and are close to the router, use the 5 GHz band.On the other hand, if they need little connection speed or they are far away, it is best to use the 2 network.4 GHz.

In addition, obstacles must be taken into account.In the case of the band of 2.4 GHz, is less sensitive to walls and other obstacles that may be.On the other hand, the 5 GHz can be affected by walls, walls or anything that makes the signal do not pass correctly.It is another factor that we must control and thus, according to the circumstance, choose one or the other.

Also whenever you have the router next door, try to use an Ethernet network cable since we will always get a faster speed and a more stable connection, especially if we are going to transfer a lot of information.

The next thing we are going to do is put examples with a series of equipment that we usually have in our homes.

PCs and laptops

Both PCs and laptops usually require an important connection rate.They may need to carry out tasks as demanding as:

Ideally, whenever the router is close, it is the network cable, as I mentioned earlier.However, this is not always possible and in this case it is best to use the 5 GHz network unless these devices are very far from the router, and they have to connect yes or yes to the 2 band of 2.4GHz.

But to watch streaming videos at maximum speed, download or upload files to the cloud and use the maximum bandwidth, the 5 GHz band will always be better.Once again, we will have to control the distance with the router and possible obstacles that can interfere.

Smart TV and Android TV

These devices also require important bandwidth for proper operation.Many of the TV conventional channels have their app so you can see in deferred the program or series that you could not see at the time.In addition to that, we have to add payment platforms such as Netflix, Amazon, HBO or Disney+.

Our first option would always be the Ethernet network cable, but sometimes we do not have the router next to the TV to make it possible, so in this case, our recommendation would be the 5G Wi-Fi, especially if we have the router inthe same room or in one of the adjoining.Ideal especially if you reproduce content in 4k.

The 2 network could also be used.4 GHz provided that streaming does not exceed Full HD resolution, or if it is quite far from our Wi -Fi equipment.

Smartphones and tablets

The first thing to point out that not all smartphones and tablets are compatible with 5 GHz networks.However, with the 2 network.4 GHz everyone can work.The easiest way to check it on Android is to go to settings, wi-fi and look at it.There you should appear the two ssid or names of your wi-fi network.If only one appears, that means that it is only compatible with the 2.4 GHz, or that in your router you have a SSID for the two frequency bands with Band Steering, so you will have to connect and see the Wi-Fi state to see which frequency band you have connected.

The advisable if you are close to the router, is the use of the 5 GHz, especially if you are going to watch videos on YouTube or make video calls.However, for use in farther stays, the use of the 2 network would be more recommended.4 GHz, especially because mobiles have very small antennas and allow very little signal reception.

IP cameras per wi-fi, smart plugs and other devices

In this case it is best to use the 2 network.4GHz.An important reason is that devices such as smart plug.Another point would be that, even if they are far from the router, they can work correctly.

In the case of smart plugs, the bandwidth you need is a few kbps to receive or send the activation or deactivation signal, in addition, their firmwares are very little size so updating it would not be a problem either.

With this series of examples, it is clear that you must connect your devices to the corresponding network and depending on your needs and requirements.Thus, depending on the connection speed and the distance you are from the router you will choose the 2 network of 2.4 GHz or 5 GHz, and you can even connect it via cable.
