Industrial IoT has special communication requirements, including high reliability, low latency, flexibility, and security. These are instinctively provided by the 5G mobile technology, making it a successful candidate for supporting (IIoT) scenarios. The aim of this paper is to identify current research challenges solutions in relation 5G-enabled IoT, based on initial requirements promises both domains. methodology follows steps surveying state-of-the art, comparing results further...
Autonomous vehicles are at the forefront of interest due to expectations changing transportation for better. In order make better decisions on road, use information from various sources: their own sensors, messages arriving surrounding and objects, as well centralized entities—including Digital Twin. Certain require arrive with low latency some this (such video) requires broadband communication. Furthermore, can populate an area, so they represent mass communication endpoints that still need...
While mobile network operators have started announcing their 5G-capable implementations, practical details of capabilities are not widely supported through measurements. This paper describes a practically implemented 5G architecture – based on the Option 3x reference model and initial results its KPI (Key Performance Indicator) measurements.Beside being matched against expectations, compared to our actual hands-on 4G The analysis testbed result shows that as expected outperforms in all basic...
The family of cellular mobile telecommunications standards – including 5G is mostly defined by the 3GPP standardizing organization. While these are well known in unfamiliar with concepts and content documents. It essential to define designate how different from existing wired wireless technologies, what main business benefits, key potential areas according new technology achievements. In our work, we present some fundamental aspects potential, where motives lay regarding Industry 4.0...
A spectacular measurement campaign was carried out on a real-world motorway stretch of Hungary with the participation international industrial and academic partners. The resulted in vehicle based infrastructure sensor data that will be extremely useful for future automotive R&D activities due to available ground truth static dynamic content. aim twofold. On one hand, road geometry mapped high precision order build Ultra High Definition (UHD) map test road. other vehicles—equipped...
Industrial IoT (IIoT) has revolutionized production by making data available to stakeholders at many levels much faster, with greater granularity than ever before. When it comes smart production, the aim of analyzing collected is usually achieve efficiency in general, which includes increasing but decreasing waste and using less energy. Furthermore, boost communication provided IIoT requires special attention increased safety security. The growth machine learning (ML) capabilities last few...
To analyze next-generation mobile networks properly, there is a need to define key performance indicators (KPIs). Testing signaling only or just partial domains of the network have been replaced with end-to-end testing methodologies. With appearing machine-to-machine (M2M) applications, this question became even harder, since no direct user feedback. Quality experience cannot be measured accurately in M2M if operates correctly and without failures. There are dozens new—but...
The Industry 4.0 initiative has been showing the way for industrial production to optimize operations based on collecting, processing, and sharing data. There are new requirements floor: flexible but ultra-reliable, low latency wireless communications through interoperable systems can share Further challenges of data storage arise when diverse come into play at Manufacturing Operations Management Business Planning & Logistics levels. emerging complex cyber-physical need be engineered...
Industrial automation systems require communication technologies with high availability, security and low latency.

It identifies main challenges research gaps regarding offers initial thoughts how these can be addressed with complex theory. As I am in early stages my doctoral research,...
Industrial networks - both wired and wireless have been used by manufacturing plants factories for many years. These are not always considered as primary elements of industrial architecture, although they should be. With the advent Industry 4.0, there already innovation initiatives, industry recommendations, standards in topic network infrastructure but integration guidelines on 4.0 networking architectures incomplete. In absence a better methodology, usually over-designed, still rigid ready...
