4G, LTE, LTE-A; these are only part of the commonly used words and phrases that are used in the technology field and, if you do not understand them correctly, they are meaningless and even meaningless.
The difference between 4G and LTE is one of the simplest and most commonplace issues, but many people do not know their answer, and manufacturing companies and mobile operators are using them abundantly to confuse their users. For a better understanding of the difference between these two networks, it may not be a bad thing to go back a little backwards, and have a look at the early generations of mobile networks.
When third-generation networks were provided to users, as can be imagined, instead of 2G or second-generation networks, 2G was actually a network protocol that provided the most basic prerequisites for today’s advanced smartphones.Most 2G networks could only handle voice calls, send and receive text messages, and transfer small amounts of data through protocols such as MMS.
With the introduction of 3G standard, users have been given more extensive data formats, including HTML, video and music pages; in other words, with the launch of these networks, users could have content other than the photo Also, send them to their audience. However, data transfer speeds were still very low, and therefore web pages and various data were transmitted through these communications. Of course, from the 2G standard, mobile communications were faster than ever before, however, they were not comparable to those of home broadband communications.
The United Nations International Telecommunication Union’s radio unit is the United Nations’ official body that regulates and makes decisions on all forms of communication technology, and passed the specifications of the 4G standard by the same organization in March 2008.
According to the decision of the organization, the maximum download speed with 4G should be 100 Mbps for use while on the move, that is, when you are riding a car or moving on a train to a destination, the maximum download speed with the 4G network is equal to the amount that we said .
But in cases where you do not have a move and you’re staying at a point (that is, you have a low mobility) and you use the mobile, this should be about 1 gigabits per second. Now, maybe this question is about why your 4G communication speed is far from the declared value.
When these standards were introduced, the speeds we mentioned were not operational in the real world, and it was impossible to achieve them; the reason is that these speeds were in fact a sort of target for technology developers, a point in the future with a significant leap It showed the technology of its time. But the systems supporting these networks reached the announced speeds, not only because of the widespread use of new communication methods in products, but because previous fixed 3G networks reached a point of progress. Which could be categorized in Group 4G.
The word LTE is taken from long term evolution or long-term evolution, and can not be considered as a new technology, like the 4G, and the path to reach its high speeds. In fact, LTE is the latest version of the 4G, which should provide download speeds of up to 100 Mbps. When the International Telecommunication Union announced the minimum speed for 4G communications, the figures were a little unattainable, and the enormous amount of capital injected by the manufacturing companies to realize it did not have a significant effect on its realization. In response, however, this legislature concluded that if the speeds provided in the new networks were a remarkable improvement compared to the third generation, then LTE instead of 4G would be used.
It did not take long for telecommunications companies to use the term 4G LTE (meaning long-term evolution of the fourth generation network) to refer to their services; a kind of marketing technique that allowed them to claim a new generation of mobile communication to their users. Without the need to comply with the speeds announced by the International Telecommunication Union. This technique can be likened to the American tricks that they claimed were landing on the surface just because they were close to the moon and their spacecraft were better than the previous generation.However, the use of this phrase by companies can not be considered a deception because, despite the speed of inconsistencies (depending on the location and type of network), 3G detection from 4G can easily be done.
But the complexity of these terms becomes even greater when you know that there is another standard called LTE-A. This term is taken from Long Term Evolution Advanced, meaning LTE Enhanced, and brings users closer to the promised speed for 4G. This standard also brings faster and more stable speeds than LTE, while it also comes in compatible with gadgets that support the previous standard and can work with aggregation of channels; that means instead of connecting to the strongest signal In the vicinity of you, the data is downloaded at the same time from several sources.
So the real question is: Can the difference between 4G and LTE networks be detected? Will downloading a page load or downloading an app on your mobile will be very different if supported by LTE technology? Probably not good unless you live in cities. While the difference between slower 3G networks and 4G or LTE networks is significant, the upload and download speeds of many 4G and 4G networks are virtually identical. But with the introduction of LTE-A and the launch of supporting networks, the difference was gradually felt, and now LTE-A is the fastest wireless network in the world.
Establishing 4G communication requires two factors:
- A network that supports specified speeds for data transfer
- A device that can connect to that network and download information at high speed.
Just because the mobile has 4G LTE connectivity, it means that you can use the same speed as the user of that phone.Just as buying a car with a maximum speed of 200 km / h can not mean that you have the necessary permissions to move with this speed.
Across the globe, mobile operators also sold phones that had the capabilities to deliver these speeds before mobile operators gave LTE speed to their users, Limited in some parts of the world.
What is the next step?
The world’s leading mobile operators are currently testing the fifth-generation mobile broadband connection called the 5G, but there’s still plenty of work to be done. In addition, so far, the standards for the agreed agreement have not been finalized and, as a result, we can not expect to see these networks before 2020, although a Qatari company just announced that it had succeeded And Samsung has also announced the success of the network on the baseball field .Considering the progress of the 4G networks in the world, it can be concluded that the multi-dimensional uptake of these networks is far away.
