IMT-2020

IMT-2020 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand IMT-2020 rather than just read about it. In short: International Mobile Telecommunications-2020 (IMT-2020 Standard) are the requirements issued by the ITU Radiocommunication Sector (ITU-R) of the International Telecommunication Union (ITU) in 2015 for 5G networks, devices and services. On February 1, 2021, the standard was published as Recommendation ITU-R M.2150-0 titled Detailed specifications of the radio interfaces of IMT-2020, but most of it was finalized years…

Key takeaways

IMT-2020 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect IMT-2020 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of IMT-2020 from memory before moving on to harder problems.

Reference excerpt

International Mobile Telecommunications-2020 (IMT-2020 Standard) are the requirements issued by the ITU Radiocommunication Sector (ITU-R) of the International Telecommunication Union (ITU) in 2015 for 5G networks, devices and services. On February 1, 2021, the standard was published as Recommendation ITU-R M.2150-0 titled Detailed specifications of the radio interfaces of IMT-2020, but most of it was finalized years earlier. For example the requirements for radio access technologies listed below were adopted in November 2017. Following the publication of the requirements the developers of radio access technologies such as 3GPP and ETSI are expected to develop 5G technologies meeting these requirements. 3GPP is developing radio access technologies 5G NR, LTE-M and NB-IoT that together are expected to meet all requirements, while ETSI is developing DECT-2020 NR and Nufront is developing EUHT (Enhanced Ultra High Throughput).

Requirements The following parameters are the requirements for IMT-2020 5G candidate radio access technologies. Note that these requirements are not intended to restrict the full range of capabilities or performance that candidate for IMT-2020 might achieve, nor are they intended to describe how the technologies might perform in actual deployments.

Worked examples

Example 1 — a first encounter with IMT-2020

Start with the simplest possible case. Write down what IMT-2020 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to IMT-2020 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about IMT-2020 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of IMT-2020

In research: IMT-2020 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses IMT-2020 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: IMT-2020 is common in secondary-school and first-year university syllabi. It links to neighbouring topics ITU-R recommendations, Mobile telecommunications standards, so understanding it makes those chapters shorter.
In everyday life: Look for IMT-2020 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
