Practical Aspects for the Integration of 5G Networks and IoT Applications in Smart Cities Environments

Summary of near-term 5G service-deployment activities (2019 view).

Country or Region	Near-term 5G Activities
South Korea	Korea Telecom rolled out a trial 5G network in support of the 2018 Winter Olympics in Seoul, South Korea covering events in several cities. It has also launched a VR/AR games platform supported from the cloud over 5G. SK Telecom has acquired spectrum in the 3.5 GHz and 28 GHz frequencies in preparation of deploying 5G.
China	China plans early implementations of 5G. The GSMA estimates that by 2025 China will represent 40 percent of global 5G connections. According to the GSMA, with 460 million projected users China is expected to become the world’s largest 5G market by 2025, higher than Europe’s 205 million and the United States’ 187 million combined. China’s three major mobile operators - China Mobile, China Unicom and China Telecom - are rolling out trial operations of 5G systems in several cities, and all three aim to fully commercialize the technology by 2020 [66].
India	5G trials are contemplated by late 2019 and early deployments may happen late in 2020.
Japan	NTT DoCoMo demonstrated an advanced security service based on 5G network technology for use in the 2020 Olympics.
United States	Migration from the 4G networks should be relatively simple. The FCC has been making several new bands available as noted elsewhere. Verizon has been aggressive in its advertisement campaigns about its introduction of 5G-related services.
Europe	T-Mobile is preparing for the rollout of 5G in 2020, starting in the Netherlands. Some fear that Europe risks falling behind other regions because of restrictive regulation and weak investments; less than half of the countries in Europe have actually allocated spectrum for 5G [67].
