GEOG2147 Building Smart Cities with GIS Prof. Winnie Tang Mr. Kelvin Shum Adjunct Professor Adjunct Assistant Professor Department of Geography Lecture 3 Enabling Technologies for Smart City Leverage on Technologies For Better City Management ICT is the backbone of any society that wants to achieve “smart” status GEOG2147 | By Prof. Winnie Tang GIS 2 What is Internet of Things ( IoT ) ? IoT , Internet of Things Everything is connected Tying together the physical, digital and analytic worlds GEOG2147 | By Prof. Winnie Tang 3 Connectivity and the “ Any ” Dimension IoT allows people & things to be connected Anytime at Anyplace with Anything and Anyone using Any Network and Any Service: GEOG2147 | By Prof. Winnie Tang 4 A Comprehensive Definition from IERC - (European Research Cluster on the Internet of Things) The IERC is actively involved in ITU-T Study Group 13, which leads the work of the International Telecommunications Union (ITU) on standards for next generation networks (NGN) and future networks and has been part of the team which has formulated the following definition: “Internet of things (IoT): A global infrastructure for the information society, enabling advanced services by interconnecting (physical & virtual) things based on existing & evolving interoperable information & communication technologies. – NOTE 1 – Through the exploitation of identification, data capture, processing & communication capabilities, the IoT makes full use of things to offer services to all kinds of applications, whilst ensuring that security and privacy requirements are fulfilled. – NOTE 2 – From a broader perspective, the IoT can be perceived as a vision with technological and societal implications." The IERC definition states that IoT is "A dynamic global network infrastructure with self-configuring capabilities based on standard & interoperable communication protocols where physical & virtual “things” have identities, physical attributes, & virtual personalities & use intelligent interfaces, & are seamlessly integrated into the information network". (Source: http://www.internet-of-things-research.eu/about_iot.htm) GEOG2147 | By Prof. Winnie Tang 5 IoT Evolution Starts with only network & evolves into everything that can be connected with a network GEOG2147 | By Prof. Winnie Tang 6 Characteristics of IoT ❖ Dynamic Changes ❖ Heterogeneity ❖ Things-Related Services Characteristics of IoT ❖ Inter-Connectivity ❖ Enormous Scale GEOG2147 | By Prof. Winnie Tang 7 Architecture of IoT Information Application Integrated Application Layer Information Processing Management Layer Information Transmission Network Construction Layer Information Generation Sensor and Identification Layer GEOG2147 | By Prof. Winnie Tang 8 Sensor & Identification Layer Lowest Abstraction Layer With sensors we are creating digital nervous system.

It is a wide area wireless technology which enables ubiquitous connections. Anything can be connected to the network from anywhere, regardless of its distance. Part of the global 3GPP Release 13 standard published in June 2016 optimized for Low Power Wide Area (LPWA) applications. Advantages: – Low Power: Battery life up to 10 years – Low Cost: Cost-effective and affordable enough for mass-scale deployment – Enhanced Coverage: Covers heavily shadowed environments – Massive Deployment: Billions of connections (source: https://www.astri.org/tdprojects/narrowband-internet-of-things-nb-iot/) GEOG2147 | By Prof. Winnie Tang 18 LoRa LoRa = Long Range Radio Long range, low power consumption connection Provide secure data transmission The physical layer or the wireless modulation scheme utilized to create long distance communication link LoRaWAN: a protocol specification built on top of the LoRa technology developed by the LoRa Alliance. Use unlicensed radio spectrum in the Industrial, Scientific and Medical (ISM) bands to enable low power, wide area communication between remote sensors and gateways connected to the network.

There is no single definition, let’s take a look from Wikipedia: – Big data is a term for data sets that are so voluminous and complex that traditional data processing application software are inadequate to deal with them. Challenges include capture, storage, analysis, data curation, search, sharing, transfer, visualization, querying, updating and information privacy. – The term "big data" tends to refer to the use of predictive analytics, user behavior analytics, or certain other advanced data analytics methods that extract value from data, and seldom to a particular size of data set. – Analysis of data sets can find new correlations to "spot business trends, prevent diseases, combat crime and so on.
