There is no doubt that the next iPhone will support the 5G networks, and according to all the information and reports that have some degree of reliability on the Internet, the iPhone phones will operate the fifth generation networks using the 5G modem from Qualcomm, but you may not know that the fifth generation networks in reality differ In terms of performance from one type to another, and from one provider to another, and today we will talk to you about the fifth generation networks in the next iPhone, along with explaining the difference between the types of 5G networks such as mmWave and Sub-6GHz in terms of speed and technology.

What is the difference between mmWave and Sub-6GHz

Fifth generation networks, as its name shows, is the fifth generation of cellular wireless networks, and it is the successor to the fourth generation 4G LTE networks currently spread in most countries of the world and our Arab countries, and simply there are two main types of fifth generation networks, which are mmWave and Sub-6GHz, The first type is the fastest and strongest, and the second is the least developed but is currently the most widespread.

Smartphones - and similar devices - transmit voice and information during calls and connect to the Internet via electromagnetic radio waves, and each of the aforementioned networks depends on different frequencies, while the two technologies differ mainly in the speed of transmitting that data along with other differences.

The mmWave technology depends on and refers to the frequencies between 24 GHz and 40 GHz, and as the number shows, they are very high frequencies and the height here reflects the speed and pioneering performance, while the Sub-6GHz technology refers to the medium to low frequencies, and as its name shows, the frequencies of this technology Below 6 GHz, it ranges from just 1 GHz for the low frequencies all the way down to 3.4 and 6 GHz for the medium frequencies.

As long as mmWave technology is excellent in this way, why is it not adopted?

Right, that's an excellent question from you! (Or from me), mmWave networks are very fast, insanely fast, but their flaw is very serious, which is that Short termThis simply means that you have to be in only one square of the mmWave communication tower in order to capture the network well, and this means that for this technology to be applied in a city, this needs thousands of towers, which is a very large cost, taking into account the obstacles Which obstructs the passage of waves on the one hand, and harms health on the other hand, which no one cares about!

The limited extent of mmWave networks' connectivity has made their use the preserve of scientific and research organizations (and certainly the military) along with some luxurious places around the world as well as crowded places as well, and if you are asking why, the answer is simply that 4G LTE networks slow down terribly in the event of Heavy congestion, in contrast to mmWave networks which handle a large number of users at the same time.

Below we share with you illustrations of the use of fifth generation networks and its comparison with fourth generation networks, as well as the time that users spend in using those networks, and it shows us the State of Kuwait side by side with the Kingdom of Saudi Arabia.

Isn't it great for Saudi Arabia to be on top of the world in the speed of the XNUMXG network and supports mmWave networks, something we really are proud of


What is the relationship of the above with the iPhone that supports fifth generation networks?

To put it simply, we and so far do not know the technologies that the next iPhone will support with certainty, and what we have previously shared are rumors of greater reliability, but most likely the situation will be as follows:

IPhone 12 and iPhone 12 Max - the two weaker versions - will only support Sub-6GHz networks
IPhone 12 Pro and iPhone 12 Pro Max - which are the most powerful - will support mmWave networks, and if they are not available, they will connect to Sub-6GHz networks normally.


How fast are all the aforementioned networks?

The difference between mmWave and Sub-6GHz in terms of speed is really huge, the faster and more powerful mmWave networks will offer speeds of up to 5Gb / s, which is amazing speed, but according to Some experiences The speed depends entirely on how close you are to the communication tower on the one hand, and the number of obstacles that separate you from the tower.

The Sub-6GHZ network currently deployed is centered between mmWave and traditional 4G, and offers speeds of up to 200Mb / s - which is much lower than the previous one - while the 4G LTE networks we are currently using offer speeds of up to 35Mb / s.

What do you think? Are XNUMXG networks available in your country yet? It is reported that the availability of mmWave networks is still very limited, and it is unlikely that it will reach most countries soon.
