Multi-Band Heterogeneous Wireless Network Architecture for Industrial Automation: A Techno-Economic Analysis

Abstract

To attain automation across different applications, industries are beginning to leverage advancements in wireless communication technologies. A "one-size-fits-all" solution cannot be applied since wireless technologies are selected according to application needs, quality of service requirements, and economic restrictions. To balance the trade-off between technical and economic requirements, a multi-band heterogeneous wireless network architecture is presented and discussed in this paper. Wireless local area network (WLAN) and distributed antenna system (DAS) with Long Term Evolution (LTE) are considered as the backbone for the multi-band heterogeneous network into which other wireless technologies can be integrated. The technical and economic feasibility of the network are evaluated through a techno-economic analysis (TEA). The economic feasibility of the proposed network is measured in terms of net present value while the technical feasibility is measured in terms of network throughput and latency. Finally, network performance for DAS with LTE and WLAN are verified using an NS3 simulator for machine-to-machine, real-time video, and high-definition video data transmissions. The TEA analysis showed that the number of DAS units required to achieve technical feasibility is less than WLAN units, but the overall cost of DAS units are higher compared to WLAN units, even without taking into consideration industrial, scientific, and medical band technologies.

Development of an End State Vision to Implement Digital Monitoring in Nuclear Plants

“…To enable the installation of wireless sensors on plant assets, a wireless architecture based on a distributed antenna system (DAS) to support multiple communication types was evaluated. Idaho National Laboratory studied a wireless network deployment strategy that would enable applications ranging from low-to high-power needs, low-to high-frequency ranges, and short-to long-range communica-tions, as seen in Figure 2 (Manjunatha & Agarwal, 2022).…”

“…A one-size-fits-all solution is not an option, considering the diverse range of wireless technologies, each with different quality of service, latency, and bandwidth requirements (Barker, 2017;Manjunatha & Agarwal, 2022). Therefore, a heterogeneous network may be highly desired.…”

Verification and validation of developed short-term forecasting models

“…This report is the latest in a series of documents detailing online monitoring, wireless communication networks, and the development of diagnostic and prognostic models using heterogenous data regarding critical balance of plant equipment in NPPs [2][3][4][5][6][7]. The previous documents in this series evaluated potential wireless technologies and communication networks inside NPPs, based on their performance and economics [2][3][4][5]; assessed vibration sensors with wireless capabilities [6]; developed formal methodologies for cleaning data and objectively comparing ML prognostic models [7]; and development of condition-based monitoring and preventative-maintenance optimization [8].…”
