2 Internet of Things (IoT, MTC, M2M) Apps Cloud Data Analytics Machine to Machine (M2M) Machine Type Communications (MTC) The Internet of Things (IoT) Devices Artificial Intelligence Big Data Sensors Source: For information purposes only

3 Internet of Things IoT is the infrastructure of the information society. It enables a wide range of devices to be sensed or controlled remotely and to exchange data through connection to the Internet network infrastructure.

4 Characteristics & Applications Low energy consumption Low cost per device High number of connected devices Other characteristics: Long range communications Ultra-low latency and high reliability Low data rate/small message size Example of Applications: Spectrum for IoT Unlicensed and Licensed bands Home automation, automotive, healthcare, industrial, environment, agriculture, smart cities, monitoring

5 Spectrum for IoT IoT is a concept encompassing various platforms, applications, and technologies that are, and will continue to be, implemented under a number of radiocommunication services The implementation of IoT currently does not require specific regulatory provisions in the Radio Regulations ITU-R is invited to conduct studies and develop ITU-R Recommendations, Reports and/or Handbooks Source: Resolution ITU-R Studies related to wireless systems and applications for the development of the Internet of Things

6 Spectrum for IoT The spectrum requirements and standards for IoT wireless access technologies and techniques are being addressed in ITU-R, including: harmonization of frequency ranges, technical and operating parameters used for the operation of short range devices standards for wide area sensor and actuator network systems spectrum to support the implementation of narrowband and broadband machine-type communication infrastructures support for massive machine-type communications within the framework of the standards and spectrum for IMT-Advanced (4G) and IMT-2020 (5G) use of fixed-satellite and mobile-satellite communications for IoT

7 Unlicensed Bands Licensed exempt status Broad Harmonization of technical and operating parameters Bands designated for ISM (Industrial, scientific and medical applications) and SRDs (Short Range Devices) Example of Frequency bands under consideration: 900 MHz, 2.4 GHz, 5.8 GHz Technical & operating parameters and spectrum use for SRDs (Rep.

ITU-R M.2224 WASN support machine-to-machine communications to a large number of sensors and/or actuators. Recommendation ITU-R M.2002 Objectives, characteristics and functional requirements of wide-area sensor and/or actuator network (WASN) systems. The key objective of WASN systems is to support machine-to-machine service applications irrespective of machine location.

The Report provides detailed information for system design policy, the wireless applications and examples of WASN systems for information sharing. Studies by ITU-R WP 5A

11 Licensed Bands Defined levels of QoS High reliability and interoperability Compatibility of consumer devices with cellular networks Uses existing ecosystem and infrastructure Example of Frequency bands under consideration: 700 MHz, 800MHz, 900 MHz, 1.8 GHz IMT bands

12 Licensed Bands Studies on the technical and operational aspects of radio networks and systems, as well as spectrum needed, including possible harmonized use of spectrum to support the implementation of narrowband and broadband machine-type communication infrastructures, in order to develop Recommendations, Reports and/or Handbooks, as appropriate, and to take appropriate actions within the ITU Radiocommunication Sector (ITU-R) scope of work WRC-19 agenda item 9.1 issue (Reference: Circular Letter CA/226) Sources: Resolution 958 (WRC-15) Urgent studies required in preparation for WRC-19 Annex item 3 Studies by ITU-R WP 5D

16 Satellite Systems Satellites cover a wide area with high capacity and can instantaneously connect any place within their footprint, allowing rapid connection of cities, villages, businesses and homes with a predictable quality of service. Less vulnerable to natural disasters than their terrestrial counterparts preferred delivery method for highly secure and mission-critical services. Both geostationary and non-geostationary satellite networks may help accelerate the development of IMT. Provide high speed backhaul connectivity to individual planes, trains and vessels and efficient backhauling of aggregated IoT traffic. E.g. IoT devices on containers (e.g. for tracking and tracing) connected to a transport vehicle such as a ship, train or truck. Studies by ITU-R WP 4B

17 Summary A variety of radio technologies will be used to implement the Internet of things in both unlicensed bands and licensed bands. The ITU-R Study Groups are developing technical and operational standards to facilitate the deployment of IoT on a global basis, including harmonized frequency spectrum and appropriate regulatory regimes. Associated aspects will also be addressed at the forthcoming WRC- 19 agenda items 1.11, 1.12, 1.13, 1.16 and 9.1 (issues & 9.1.8) Your participation in these activities is welcome!
