ABSTRACT

Connected living ¡ the true vision of the Internet of Things (IoT) – offers improvement in the quality of life while presenting new business avenues. A combined effort by researchers, industries, manufacturers, service providers, and other stakeholders is required to address distinct IoT requirements. This convergence is expected to unleash a new dimension of opportunities that cannot be fully realized with conventional solutions. At the same time, 5G wireless promises a new connected ecosystem with potential technologies, like massive Multiple-Input and Multiple-Output (MIMO), Cloud Radio Access Network (C-RAN), Heterogeneous-CRAN (H-CRAN), mmWave, softwaredefined networking, information (content or data)-centric communication, Multi-RAT, and novel multiplexing. Since emerging 5G network is expected to revolutionize the way of communication, its design and standardization should consider IoT as one of the major guidelines. To this regard, we present technical details of emerging 5G networks inline with pressing IoT requirements, essential for the ultimate shaping of a connected living. We also delineate limitations of legacy networks to provide for peculiarities of IoT requirements.

5. CONCLUSIONS

As a part of 3GPP standardization, 5G wireless is undergoing major evolution. Cellular standards are now adding techniques to improve network capacity as well as quality. While the legacy network falls short of fulfilling IoT requirements, ongoing discussions around C-RAN, HetNets, Massive MIMO, mmWaves, and non-orthogonality strengthen the viability of an IoT era. 5G offers a paradigm shift in interoperability of devices, applications, and services, compared to the quick-fixes in legacy networks. In this article, we point out distinct IoT requirements and how 5G offers to address them. An organized research effort to overcome the challenges of IoT in 5G era would lay a strong foundation for a connected living.
