International Mobile Telecommunications IMT systems will be able to provide a significant improvement in performance and quality of current IMT services, such as Mobile Broadband MBBand also fulfil requirements of a wider range of telecommunication services including emerging services that had not traditionally employed IMT technologies. Such services or use cases raise stringent requirements on throughput, reliability, latency, mobility, number of concurrent connected devices, and energy efficiency among others.

A use case is defined as a description of the behaviour of individual users, groups or users or an application process. The original goal of IMT was to provide access to a wide range of telecommunication services supported by fixed and mobile telecommunication networks. However, the capabilities of IMT technologies have proven to be applicable to specific industries in wide-ranging closed environments. Some of these IMT applications have already been investigated e.

It is useful to cover in one Report all these applications of IMT in specific industry sectors, by referring to relevant Recommendations and Reports where they exist and addressing in the Report the remaining ones that have not yet been fully documented.

This Report provides information on the usage of IMT systems for emerging use cases or applications such as Intelligent Transport Systems ITSrailways or high speed train communications, industry automation, remote control, etc.

This Report does not preclude the development of new use cases or applications that exist or appear in future IMT technology development and deployment or other applications that can be provided by the satellite component of IMT or other systems. For instance, Rec. ITU-R M. ITU-R 66 is also relevant. This section should also include information on narrowband and broadband MTC. The Internet of Things IoT is quickly emerging as a very significant agent of transformation as it blends the physical and digital worlds; indeed, billions of connected devices are forecasted by the year For service providers this represents an opportunity for increased revenues and for vertical networked industries; this represents more efficient operations.

Since MTC cuts across all verticals general aspects, it can be covered in this section. Intelligent Transport Systems ITS applications are typically classified into three groups: safety, traffic control and infotainment. Safety applications aim at protecting the road users pedestriansthe driver and the vehicle itself.

Examples of such applications include cooperative active safety systems to warn drivers about dangerous situations and intervene through automatic braking or steering to avoid accidents, cooperative driving applications, such as platooning, to reduce accidents and increase road safety and traffic efficiency.

In addition, communications between vehicles and vulnerable road users pedestrians, cyclists through their mobile devices will be an important key element to improve traffic safety and to avoid accidents.Search for:. RSS Feed Shopping cart. Page Content. An ITU-R Handbook is a text which provides a statement of the current knowledge, the present position of studies, or of good operating or technical practice, in certain aspects of radiocommunications, which should be addressed to a radio engineer, system planner or operating official who plans, designs or uses radio services or systems, paying particular attention to the requirements of developing countries.

It should be self-contained, require no familiarity with other ITU Radiocommunication texts or procedures, but should not duplicate the scope and content of publications readily available outside the ITU. It is intended for the use by administrations of both developing and developed countries and by the Radiocommunication Bureau.
