As 5G networks are being deployed across the world, more and vertical industries discovering benefits of connectivity novel business innovation models that it has to offer. The Transport & Logistics (T&L) industry is expected be one key adopters technology, where enterprise market for T&L estimated reach $2.9 trillion (€2.7 trillion) by 2026 grow at a CAGR 47.5% [1]. However, adoption penetration 5G-based solutions in may hindered knowledge/expertise gap between industry, telecommunication...
Just before the commercial roll-out of European 5G networks, trials in realistic environments have been recently initiated all around Europe, as part Phase 3 projects 5GPPP H2020 program [1]. The goal is to showcase 5G's capabilities and convince stakeholders about its value-adding business potential. approach offer advanced connectivity real vertical industries how it enables them overcome existing 4G network limitation other long-standing issues. EVE project [2] offers cutting-edge...
The fifth-generation (5G) and beyond 5G (B5G) wireless networks introduced massive machine-type communications (mMTC) to cope with the growing demand of Internet Things (IoT) applications. However, heterogeneous characteristics IoT diverse quality service (QoS) requirements may lead severe interference that could degrade expected QoS cellular ecosystem. Therefore, this article studies impact caused by mMTC connections. We theoretically model intercell (ICI) minimization problem for existing...
In Information Centric Networks, each node on the Data delivery path has ability to cache data items that flow through it. However, takes decision whether a particular item or not independently from other nodes path. This approach might result in an inefficient usage of such in-network caching capacity and lead reduced network robustness performance. this paper, we propose BidCache, method allows situated traversed by Interest participate auction win right which will be returned for...
The 5G EVE project has developed a multi-site experimental architecture for European end-to-end experimentation platform. main objective of EVE's innovative is to facilitate the definition, execution and validation experiments designed by verticals, mainly focused on testing validating KPIs vertical services top an infrastructure. This paper explains describes workflow defining, executing analyzing results experiments.
The next generation of mobile networks, namely 5G, promises significant qualitative and quantitative advances for multiple vertical domains. However, most studies investigations assess these under the implicit assumption a single network service provider, with typical national coverage. In this article, we take close look at automotive sector highlight series challenges emerging in context its inherent (inter)national mobility corresponding importance cross-border and/or multioperator...
By delivering end-to-end latencies down to 5ms, data rates of up 20Gbps, and ultra-high reliability 99.999%, 5G is extending the capabilities numerous industry verticals, including Transport & Logistics (T&L). As T&L has a pivotal role in modern production distribution systems, it expected leverage technology significantly increase efficiency safety operations, through automating optimizing processes resource usage. However, be able truly benefit from 5G, design, development, as well...
The advent of Active Antenna Systems has provided new ways and features for increasing the capacity mobile networks in order to cope with ever traffic demand. One such feature is vertical sectorisation (VS) technique where a cell divided into an inner outer sector by using second downtilted beam from one antenna. two sectors use same spectrum resources but share electrical power available. limitation available per sector, raises question whether there gain VS, if so, how much under which...
Vertical Sectorisation (VS) is a feature that exploits the capabilities of Active Antenna Systems (AAS) to improve service performance and network capacity, by splitting single cell into an inner outer sector. The attained gains primarily depend on suitable timely (de)activation VS in response observed/estimated traffic distribution within cell, while further can be achieved properly adjusting parameters such as transmit power distribution. Considering realistic LTE (Long Term Evolution)...
While 5G Non-Stand Alone (NSA) networks are quickly being deployed across multiple nations, providing a first sense of the capabilities connectivity, adoption by various vertical industry sectors and its integration into their day-to-day operations is progressing slowly. This partially due to perceived complexity deploying services over fact that stakeholders do not have clear understanding potential offerings 5G. To address that, concept Network Applications (NetApps) picking up steam which...
As the first 5G networks are being deployed across world, new services enabled by superior performance of in terms throughput, latency and reliability emerging. Connected Automated Mobility (CAM) perhaps among most demanding applications that will have to support their deployment, potential for improvement has been well investigated over past few years. However, CAM operation multi-operator environments inevitable inter-PLMN handover caused inherent mobility not studied length. Moreover,...
Internet-of-Things (IoT) devices, wearables, sensor networks and lately vehicles produce continuous streams of data. Distributing every data item to all interested applications can quickly bring the underlying network its capacity limits. Moreover, are often only in "big picture" derived from aggregates this Hence, aggregation becomes a necessary step order optimize bandwidth utilization. The standard approach is based on centralized, application-specific method, with gateways collecting...
Active Antenna Systems (AAS) technology is one of several advanced features that enable a mobile network operator to cost-efficiently increase its capacity cope with the exponential data traffic growth and ever more demanding performance requirements.

Structural Health Monitoring (SHM) systems help to monitor critical infrastructures (bridges, tunnels, etc.) remotely and provide up-to-date information about their physical condition. In addition, it helps predict the structure's life required maintenance in a cost-efficient way. Typically, inspection data gives insight structural health. The global behavior, predominantly loading, is generally measured with vibration strain sensors. Acoustic emission sensors are more used for measuring...
The Connected and Automated Mobility (CAM) services enabled by 5G connectivity are expected to change the automotive industry offering safe, secure, efficient autonomous capabilities vehicles.
