Question: 5G Network and IoT application in Smart city environment

Answer: A firm definition of 5G IoT has still to emerge, although a large number of use cases have been described by various industry entities. Both 3GPP NB-IoT and LTE-M technologies are seen at this juncture as integral to 5G services: these 4G technologies are expected to continue under full support in 5G networks for the immediate future. However, IoT/Smart City applications that require high bandwidth will need implementations of eMBB and mmWave frequencies.

Some controversy existed at press time about the development of 5G equipment, in the context of origin-of-manufacturing and the possible intrinsic risk related to cybersecurity. If these issues are not satisfactorily resolved, some delay in the broad early deployment of 5G may result. However, the expectation is that these issues will work themselves out over time.
