Abstract
The manufacturing industry is connecting people and equipment with new digital technologies, enabling a more continuous stream of data to represent processes. With more things connected, the interest in a connectivity solution that can support communication with high reliability and availability will increase. The fifth generation of telecommunication, i.e., 5G has promising features to deliver this, but the factory environment introduces new challenges to ensure reliable radio coverage. This will require efficient ways to plan the Factory Radio Design prior to installation. 3D laser scanning is used at an ever-increasing rate for capturing the spatial geometry in a virtual representation to perform layout planning of factories. This paper presents how to combine 3D laser scanning and physical optics (PO) for planning the Factory Radio Design of a cellular Long-Term Evolution (LTE) network (5G) in a virtual environment. 3D laser scanning is applied to obtain the spatial data of the factory and the virtual representation serves as the environment where PO computation techniques can be performed. The simulation result is validated in this paper by comparison to measurements of the installed network and empirical propagation models. The results of the study show promising opportunities to simulate the radio coverage in a virtual representation of a factory environment.
Highlights
Anything that can benefit from having a connection is expected to have one in the future [1] and with an increasing amount of things being connected, they will have a greater impact on how mobile and wireless communication systems are used [2]
Reference Signal Received Power (RSRP) is the received power averaged in linear scale (W) over reference symbol resource elements (RE) within the measurement bandwidth and given in dBm
The RSRP provides information about signal strength solely, i.e., no interference or noise information is taken into account
Summary
Anything that can benefit from having a connection is expected to have one in the future [1] and with an increasing amount of things being connected, they will have a greater impact on how mobile and wireless communication systems are used [2]. Machine-to-machine (M2M) and machine-to-person communication will be delivered by the Internet of Things (IoT) technologies offering values in terms of improved efficiency, sustainability, and safety for both the industry and for the society at large [3]. IoT provides the possibility of connecting devices directly to the Internet and. With more devices and people connected, the mobile system will have to deal with demands for constant availability, high resilience, wide-coverage, low latency, and large bandwidth [1]. Great challenges of the future network will be to meet higher traffic volume for indoor and outdoor environments, traffic
