The role of small cell technology in future Smart City applications

Abstract

Meeting citizens' requirements economically and efficiently is the most important objective of Smart Cities. As a matter of fact, they are considered a key concept both for future Internet and information and communications technology. It is expected that a wide range of services will be made available for residential users (e.g. intelligent transportation systems, e-government, e-banking, e-commerce and smart management of energy demand), public administration entities, public safety and civil protection agencies and so on with increased quality, lower costs and reduced environmental impact. In order to achieve these ambitious objectives, new technologies should be developed such as non-invasive sensing, highly parallel processing, smart grids and mobile broadband communications. This paper considers the communication aspects of Smart City applications, specifically, the role of the latest developments of Long-Term Evolution-Advanced standard, which forecast the increase of broadband coverage by means of small cells. We shall demonstrate that the novel concept of small cell fully meets the emerging communication and networking requirements of future Smart Cities. To this aim, a feasible network architecture for future Smart Cities, based on small cells, will be discussed in the framework of a future smarter and user-centric perspective of forthcoming 4G mobile technologies.

WOT Enabled Smart Cities integrated Big Data Analytics

“…Data analysts can use data from the big data warehouse to find trends and gain actionable insights. When analyzed (and in many casesvisualized in schemes, diagrams, infographics) big data show, for example, the performance of devices, help identify inefficiencies and work out the ways to improve WoT system (make it more reliable, more customer-oriented) [10].…”

A Fast and Reliable Broadcast Service for LTE-Advanced Exploiting Multihop Device-to-Device Transmissions

“…In fact, if each cell allocates SL resources autonomously, cell-border UEs will be subject to interference from UL transmissions in the neighboring cells, hence they may be unable to receive P2MP D2D transmissions. This problem is likely to affect more heavily dense networks [33], where cells are smaller.…”

Machine-to-machine (M2M) communications for smart cities

“…There are several new constituents emerging in the technology landscape of cities today [7][8][9][10][11][12][13][14][15][16][17]. Notably, cities start to roll out smart city "operating systems" or data platforms that rely on the input of data from sensors deployed in the field; data gathered from people via, for example, social media; or data taken from the Internet at large.…”
