Introduction to current dual-band routers

A electric current simultaneous dual-ring router is capable of working with 3 types of devices that we can connect through:

  1. A
    network cable
    continued to ane of your Gigabit ethernet ports or Multigigabit ports. Generally it has 4, which we could connect by using network network cables with connecting RJ-45. In addition, in order to accept advantage of the full bandwidth of the connection, it is recommended that the cable exist category 6 and up.
  2. Use the
    2.iv GHz Wi-Fi network
    , currently all devices that can be connected by WiFi can use information technology, since it is the frequency ring that has e’er been used in Wi-Fi wireless networks, so we will non accept whatsoever compatibility problem.
  3. Connecting to the
    5 GHz Wi-Fi network
    , here the issue is more than complex since there are quite a few devices that cannot connect to this frequency band. The trend is that most of those manufactured in 2020 are compatible with this blazon of network, but this does not always happen, it depends on the internal wireless carte used by the equipment, usually low-terminate devices (smartphones and tablets), they do not incorporate this functionality.

As for the network cable, information technology is undoubtedly the all-time method to obtain the highest speed that our connectedness offers, and in a more stable way. This ways that, generally, nosotros volition not accept big fluctuations in speed. In improver, we are going to get a better ping, or what is the same, a amend response time from when the packet leaves our computer until it reaches its destination, however, the most important thing is the jitter (ping fluctuation), and information technology is that we volition not have “lagazos”.

Therefore, to finish with the network cable connections to those Gigabit Ethernet ports of our dual band router, we recommend connecting the post-obit equipment:

  1. Desktop PCs nearby.
  2. A laptop that is almost always in the aforementioned place and has the router nearby.
  3. A Smart TV, game consoles and other types of multimedia devices. In many cases, especially when y’all are in the center of the house and are located next to the router, it is highly recommended to connect these devices via cable. In that case forget about WiFi, since the network cable will give you better performance.

Analysis of two.4GHz networks, regulations, advantages and disadvantages

If we desire to know which devices it is amend to connect to WiFi 2.4 GHz and which ones in 5GHz we have to start past knowing them. Now we are going to deal with the ii.iv GHz network, through its nomenclature, we will know what speed they can achieve. Then we volition turn to its advantages and disadvantages.

Now it’south time to talk about the 802.11 standard, which is a family of wireless standards created by the Institute of Electrical and Electronics Engineers. In the case of the 2.4 GHz band, current routers work with 802.11b / g / n / ax standards.

The oldest is the
standard, which was canonical in 1999. The maximum transmission speed is 11 Mbps. In real life, this maximum speed is reduced by approximately 5.nine Mbps over TCP and 7.1 Mbps over UDP. Then, in June 2003, the
standard was approved. In this case we could consider it as its natural evolution. With this mode, a theoretical maximum speed of 54 Mbps tin can be achieved. On the other hand, the real average of the existent transfer speed obtained was approximately 22.0 Mbps.

standard was approved in September 2009. In this case, the theoretical maximum speed that tin can exist reached depends on the number of Wi-Fi antennas, both internal and external, in real life at most there are computers with a total of four antennas WiFi, which are capable of providing speeds of upwards to ane,000Mbps thank you to 1024QAM quadrature amplitude modulation. A fact that nosotros must comment is that it can work in the 2.4 GHz band and in the 5 GHz band simultaneously. This standard is currently referred to every bit Wi-Fi 4.

Finally, we currently take the
802.11ax standard
, which was recently approved and we are starting to run across routers, WiFi access points, wireless network cards and other devices such as smartphones or tablets that support it. It makes apply of the same 2.4GHz band, only improves its performance to provide upwards to one,148Mbps when nosotros employ four antennas in MU-MIMO 4T4R configuration.

Regarding the 2.4 GHz WiFi band, we can comment that it operates from ii,412 MHz (channel 1) to two,472 MHz (channel 13). Therefore, we would accept a new aqueduct every 5 MHz apart. In addition, the aqueduct width is 20MHz or 40MHz, and then with a couple of Wi-Fi networks we would exist occupying most all the available spectrum.

Equally you can encounter, the inconvenience of having few channels volition cause us to accept a lot of interference with nearby networks. If you lot brand a simple check with your smartphone of the networks available in a large metropolis, obtaining a result of more than than twenty would non be strange at all.

These interferences that we suffer with nearby Wi-Fi networks cause
2.4 GHz networks to
obtain a
connection speed
much lower than 5 GHz
. In full general we could have an boilerplate maximum speed of betwixt 60 or fourscore Mbps. Even so, thank you to the fact that the frequency used is lower, we obtain its
greatest advantage
and that it is none other than that its signal
goes further

In summary, ii.4 GHz networks take less connexion speed, but in exchange, their signal coverage goes farther than those of 5 GHz networks.

Analysis of 5 GHz networks, regulations, advantages and disadvantages

The first standard to employ the 5GHz band was 802.11a, with a speed of 54Mbps maximum, exactly the aforementioned as the 802.11g standard for the 2.4GHz band. The next standard in using this frequency band was 802.11n, with the aforementioned speed and characteristics as the 2.4GHz band, merely it was a before and later on since the offset simultaneous dual-ring routers began to appear.

In the 5 GHz ring we have to talk about the
regulation that was approved in 2014. It is currently the well-nigh widely used in this ring. Another mode to name it is every bit WiFi 5, WiFi Gigabit or as WiFi 5G. Transfer rates of up to 433 Mbps tin can be obtained per data stream using 256QAM quadrature aamplitude modulation. As a maximum speed we could theoretically reach rates of 1.3 Gbps using 3 antennas, or 1.7Gbps if we utilize 4 antennas. Also, if nosotros use a 1024QAM quadrature amplitude modulation, the speed will exist 25% higher, effectually 540Mbps per data flow.

Finally, the
standard that is prepared to operate in the ii.4 GHz and 5 GHz bands. Popularly known as WiFi 6, I mention information technology then that yous know what the hereafter of our WiFi networks will be. As for 5 GHz networks, there are 21 channels of 20 MHz, as we accept more than, there volition be less possibilities for a network to coincide on the same channel, although in this case we have channel widths of 80MHz or 160MHz, and then neither is that nosotros have then many channels available, but conspicuously many more than than in the two.4GHz band.

Therefore, we can affirm that the smashing advantage that 5 GHz networks requite united states of america is that we obtain a connection speed much higher than 2.4 GHz. If nosotros apply a modernistic smartphone that supports 5 GHz networks, nosotros can obtain speeds college than 500 Mbps and even higher if we use a laptop.

On the other mitt,
5 GHz networks
considering of the frequency they use, accept a drawback and it is none other that
supports distance and obstacles such as walls worse
. This besides has its positive signal (having less coverage), since the neighbors’ Wi-Fi networks will be profoundly adulterate and will not interfere with ours.

The WiFi Alliance has already standardized the new 6GHz band, which is the perfect complement to the 5GHz ring since information technology volition permit us to connect a large number of devices without interference, past having even more than channels to connect equipment. Thanks to this decision, we will soon see routers with Wi-Fi six using this Wi-Fi frequency band.

Criteria for choosing which WiFi network to connect to

At present that we know the strengths and weaknesses of the 2 GHz and 5 GHz WiFi networks, nosotros are going to learn which type of network works best for each one. The best nosotros tin practise is written report the device and determine based on:

  1. The distance from the router.
  2. The bandwidth yous need.

a general rule
nosotros could say that
need a lot of bandwidth
, and are
close to the router, utilise the 5 GHz band
. On the other hand,
if y’all demand a depression connection speed or are far abroad,
it is best to use the
2.four GHz network

whenever you have the router adjacent to you
, attempt to use an
ethernet network cable
since we will ever get higher speed and a more stable connection, particularly if we are going to transfer a large corporeality of information.

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

PCs and laptops

Both PCs and laptops frequently require a high connection speed. They may demand to carry out tasks as demanding as:

  • View multimedia content in 4K streaming, such every bit on YouTube, Netflix or Disney + amid others.
  • Videoconferences.
  • Play online in multiplayer games.
  • Receive updates from the operating system.

Ideally, if they have a site and the router is shut by, it is the network cable, equally I mentioned earlier. However, this is not ever possible and in this case it is best to use the 5 GHz network unless those devices are very far from the router, and they have to exist connected to the 2.4GHz ring.

Smart Idiot box and Android Tv

These devices as well require pregnant bandwidth for their proper operation. Many of the conventional TV channels take their app and so yous can watch the program or series that you couldn’t watch at the fourth dimension. In addition to that, nosotros have to add together payment platforms such as Netflix, Amazon, HBO or Disney +.

Our beginning choice would e’er be the Ethernet network cable, just sometimes we do non have the router next to the Boob tube to make information technology possible, so in this case, our recommendation would be 5G Wi-Fi, specially if we have the router in the same room or in one of the bordering ones. Platonic peculiarly if you lot play 4K content.

The ii.4 GHz network could besides be used equally long equally the streaming does not exceed the Full Hard disk resolution, or if it is quite far from our WiFi equipment.

Smartphones and tablets

The showtime thing to notation is that not all smartphones and tablets are compatible with 5 GHz networks. Withal, with the 2.4 GHz network they can all work. The easiest fashion to bank check it on Android is to get to Settings, Wi-Fi and expect at it. In that location the two SSIDs or names of your Wi-Fi network should appear. If only ane appears, that means that it is only compatible with the 2.4 GHz one, or that in your router you lot have an SSID for the two frequency bands with ring steering, then you will take to connect and run across the Wi-Fi status to see which frequency band you’ve connected to.


The advisable thing if yous are close to the router, is the employ of the 5 GHz, especially if you are going to scout videos on YouTube or make video calls. However, for utilise in more remote rooms, it would be more advisable to use the ii.4 GHz network, especially since the mobiles have very small antennas and allow very little indicate reception.

Wi-Fi IP cameras, smart plugs and other devices

In this case, it is best to apply the 2.4GHz network. An important reason is that devices such as smart plugs crave a low connection speed to work well, the aforementioned goes for IP cameras because they have very piddling bitrate to function properly. Another favor point would be that, fifty-fifty if they are far from the router, they can piece of 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 improver, its firmwares are very modest so updating it would non exist a problem either.

With this serial of examples, it is clear that you must connect your devices to the corresponding network and depending on your needs and requirements. So depending on the connectedness speed and the distance yous are from the router you will choose the 2.4 GHz or 5 GHz network, and you tin even connect it via cable.
