Glossary of 5G terms that you should know to understand this technology

Every new expertise is best than the earlier one. The 5G connectivity, it is an instance. It guarantees extra pace in sending knowledge. Extra units related on the similar time. Low latency with out saturating the road at peak occasions. And, as if that weren’t sufficient, will probably be an important enhance to applied sciences such because the Web of Issues. However for get to know 5G intimately it’s a must to turn into accustomed to sure 5G phrases that you will have heard earlier than. Therefore the significance of this glossary.

Under we acquire a few of the most distinguished expressions and phrases in relation to the cellular connectivity of fifth generation, the so-called 5G. Figuring out them will enable you higher perceive how this expertise works and the way it permits smartphones and different units keep related to the web like by no means earlier than.

5G Terms - Glossary

1G, 2G, 3G, 4G, 5G

We begin this glossary with 5G phrases exactly with 5G, which suggests fifth Technology, fifth era. Meaning we’ve come throughout 4 generations alongside the way in which. To 5G cellular connectivity 4G expertise precedes it. Each presently coexist till 5G is totally deployed. It is extra. Wherein areas we nonetheless have to show to an excellent older era, 3G.

Whereas the three most up-to-date generations, 3G, 4G Y 5G, are cellular applied sciences that provide digital broadband knowledge transmission, the primary two generations, 1G Y 2G, provided, respectively, analog voice providers and 2G, digital voice providers and low pace knowledge transport. With 2G, for instance, got here the SMS textual content messages.

As a curiosity, 1G was launched within the 80s. 2G arrives in 1990 with speeds of 40 kbps. The 3G it was commercially launched in 2001 and reaches speeds of 144 kbps. The 4G it was launched for the primary time in 2009. Technically, 4G reaches speeds of between 100 Mbps and 1 Gbps, though the speeds presently provided revolve round these 100 Mbps. 5G it was first launched in 2016 and remains to be within the implementation section. Its theoretical pace is 20 Gbps. Nevertheless, for the time being the pace reached in Spain is about 200 Mbps.


Past the unique 5G glossary phrases, 3GPP is an acronym that, translated, means Third Technology Affiliation Challenge. It’s a collaboration of telecommunications associations. Its preliminary goal was to ensure the specs of 3G expertise. Its headquarters are in France, on the places of work of the ETSI (European Telecommunications Requirements Institute).

Over time he additionally launched the system GSM (in Spanish, international cellular telecommunications system). In relation to this technique there are two applied sciences recognized to those that have used 3G telephones: GPRS Y EDGE.

As a curiosity, this affiliation of associations consists of the next organizations: ARIB, ATIS, CCSA, ETSI, TSDSI, TTA y TTC.


We already know what 5G is. The second half, NR, means New Radio. 5G NR expertise is the worldwide commonplace for the radio interface of 5G networks. Behind it’s 3GPP and its deployment started in 2019.

What does this imply? What known as 5G NR corresponds to the radio frequency half that makes communication between the cellular machine and the energetic base station attainable. Once you transfer along with your 5G cellphone, this change energetic base station.

To know us, 5G NR It’s a part of the applied sciences that, encompassed, we name 5G. Its position is to make the 5G cellular community carry out properly, be versatile, scalable and environment friendly.

One other of the extra unknown 5G phrases on this glossary. DSS is the acronym for Dynamic Spectrum Sharing. In Castilian it might come to be Dynamic Forged of the Spectrum. This expertise, sponsored by the 3GPP group that we talked about earlier than, has to do with the deployment of 5G expertise.

What DSS does is permit telecommunications operators to make use of the radio spectrum utilized by LTE to provide entry to 5G connectivity. So the transition from 4G to 5G is easier.

For its half, LTE is the acronym for Lengthy Time period Evolution, in Castilian Lengthy-Time period Evolution. That is wi-fi broadband expertise. Or to grasp us, it’s on the way in which between 3G and 4G. Therefore it is usually often called 3.95G or instantly 4G LTE.


On this glossary we additionally embody the acronym eMBB stands for Enhanced Cellular Broadband, in Spanish Enhanced Cellular Broadband. It is likely one of the three pillars during which 5G connectivity stands out. The opposite two are URLLC Y MIoT.

And to grasp one another. The acronym eMBB teams collectively the purposes and enterprise fashions that require very excessive knowledge switch charges and higher service protection. In observe it covers crowded locations reminiscent of places of work or purchasing facilities.

Radioelectric spectrum

The spectrum or radioelectric spectrum couldn’t be lacking on this glossary. It encompasses lots of the 5G glossary phrases that seem on this article. The radio spectrum is one thing that we discover in nature. We do not see it however there it’s. To categorise it, we use frequency bands. To know the significance of the radioelectric spectrum: it’s the transport route utilized by applied sciences reminiscent of tv, radio, GPS, Bluetooth or WiFi that permits you to hook up with the Web with out cables.

Every expertise employs a particular portion of the radioelectric spectrum. If not, they’d overlap and there could be interference. Therefore the significance of frequency bands.

To measure the radioelectric spectrum we use hertz. Radionavigation, for instance, makes use of the band from Three to 30 KHZ. FM radio strikes between 30 and 300 MHz. And cellular telephony, relying on the era, strikes between Three MHz and 30 GHz.

That is how cellular connectivity is distributed over the radio spectrum:

  • 1G: 900 MHz
  • 2G: 900 MHz and 1.eight GHz
  • 3G: 900 MHz and a pair of.1 GHz
  • 4G: 800 MHz, 1’eight GHz, 2’1 GHz y 2’6 GHz
  • 5G: 700 MHz, 3’5 GHz y 26 GHz

5G Terms - Glossary


Latency is a “phrase” that has been talked about for years, past the glossary of 5G phrases. It’s one thing that impacts every kind of web connections. Exactly, the distinction between wired and wi-fi connections has to do with latency.

So as to not prolong ourselves, latency is the time it takes for a packet to be transmitted inside a community. If the information packets despatched and obtained are on time, all the things is ok. A low latency is important for duties that require bandwidth. That is the case of video calls, on-line online game video games, stay broadcast of audiovisual content material …


Earlier I discussed MIoT on this glossary. I mentioned it was one of many three pillars that make up the makes use of of 5G expertise. The primary pillar was eMBB and we’ve already defined it.

For its half, MIoT stands for Large Web of Issues. In Spanish, large IoT. 4G LTE expertise began the trail to the Web of Issues. That’s, join a large number of units to one another to facilitate the course of automation in skilled sectors of any subject.

However 5G expertise guarantees far more. For starters, it helps extra units related without delay in much less area. Particular, 1,000,000 units per sq. kilometer.


The acronym mMTC means, in Spanish, large machine-type communications. It consists of providing a simultaneous connection to billions of units with out saturating the community. All this utilizing a decreased quantity of knowledge.

In observe this makes attainable the existence of sensible buildings and cities during which hundreds of thousands of sensors and units they type an ecosystem related in actual time.


We end this glossary with one other of the 5G star phrases is URLLC is the acronym for Extremely-Excessive Reliability & Low Latency. This pillar of 5G expertise has to do with vital providers that require extraordinarily low latency. A few of the providers are already fairly widespread. Others are actually starting to enter their respective fields.

We discuss autonomous autos, communication between autos, transport infrastructures, business 4.0, vital infrastructures o strategic, and many others.
