Will 5G become yet another wireless technology for industrial automation?

Abstract

Abstract-With the growing interest in adoption of wireless technologies in industrial automation and the continuous search for new revenue streams new players are entering the arena in order to make their business grow further. One of the emerging wireless technologies aiming to support industrial automation applications is 5G, targeting anything from extreme throughput (> 10 Gbit/s) to extreme low latency (≤ 1 ms) to ultra high reliability (≥ 99.999%). In this article we intend to discuss the potential and challenges of adopting 5G in real industrial environments and give a more balanced picture compared to previous articles mainly written by telecom researchers and vendors as a way to promote their technology. Specifically, this article will discuss and provide some real industrial requirements, describe the main technical features of 5G and try to assess what applications it will support that are not by already supported by existing technologies. In the end, the success of 5G will depend on appealing business models and scalability, i.e., whether or not the same equipment can be deployed worldwide without any changes and spectrum rules, and the migration paths beyond 5G for reasonable business risks.

Joint Scheduling of URLLC and eMBB Traffic in 5G Wireless Networks

“…Observe that the above optimization problem can be solved separately for each network state s ∈ S. The de-coupled problem for any state s is same as the optimization problem (9) in our online algorithm. With a slight abuse of notation, let φ (s),γ(s) be the optimal solution to the online problem when S(t) = s. Conditioned on S(t) = s, we have that: The main intuition behind the proof of optimality is that for large t, the trajectories of R(t) can be approximated by the solution to the following differential equation in x(t) with continuous time t: dx(t) dt = argmax:…”

Resource Allocation and HARQ Optimization for URLLC Traffic in 5G Wireless Networks

“…Many works focus on the industrial applications of URLLC traffic and exhibit simulation based studies for such systems, see [1]- [3]. Some authors, see e.g., [18], [19] focus exclusively on physical layer aspects like modulation and coding, fading and link budget analysis.…”

Networked Electric Drives in the Industry 4.0

“…Second, these systems can serve a diversity of applications, which allows enterprises to use one single networking technology on all layers. The advantages come of course with the drawbacks of complex and costly communication hardware and the additional cost of spectrum lease [25].…”
