A feature of 5G communications is high capacity conveyance of sensor information, paramount for big data applications. However the inconsistent roll-out of 5G features hinders the development of ultra-reliable low-latency communication (URLLC), massive machine-type communication (mMTC) and dynamic network slicing. This paper introduces a hardware-based 5G test-bed that emulates dynamic slicing and large-scale sensor data processing using AI-powered resource optimization. Taking advantage of current 5G infrastructure and surrogate sensor data generation, our system enables realistic big data analytics in industrial environments. An AI-based decision tree model dynamically assigns network slices, optimizing throughput costs. Our surrogate data provides good quality supplemental sensor data, preserving key statistical and spectral properties enhancing sensor-driven big data applications. Our experiments show improved data transfers, adaptive network slicing and scalable big data processing. This offers a cost-effective solution for small/medium-sized enterprises (SMEs) and research/development (R&D) teams. This work bridges the gap between theoretical 5G slicing and real-world deployment for 5G-based big data applications. It provides a repeatable framework for industrial IoT and smart manufacturing, preparing for full commercial availability of 5G features<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup><sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup>Ministry of Education Singapore, grant 2021MOE-IF-024.

The Gas Electron Multiplier (GEM) is a new age detector, which can handle the high flux of particles. The GEM foil, which is constructed using 50$\mu$m highly insulating foil (Kapton/Apical) coated with 5$\mu$m layers of copper, on both sides, with a network of specifically shaped holes is the major component of these detectors. The European Center for Nuclear Research (CERN) has been the sole supplier of the GEM foils until recently when a few other companies started manufacturing GEM foils under the transfer of technology (TOT) agrement from CERN. Techtra is one such company in Europe which gained a right to use CERN developed technology in order to produce commercially viable GEM foils. Micropack Pvt. Ltd. is another company in India which has successfully manufactured good quality GEM foils. Due to the microscopic structure of holes and dependence on the electric field inside, it becomes essential to study the defect and uniformity of holes along with the electrical property of foils under ambient conditions. In this work we are reporting the tests condition of Techtra GEM foils. We report on the development of a cost effective and efficient technique to study the GEM foils holes geometry, distribution, and defects. We also report on the electrical properties of these foils like leakage current, stability, and discharges. At the detector level, we describe the high voltage (HV) response, gain, uniformity, and stability. The GEMs have been proposed to have a wider applications, so we performed a feasibility study to utilize these for the imaging. We irrediated various objects of varying density with X-rays and reconstructed the images. The reconstructed image shows a good distinction between materials of different densities, which can be very useful in various applications like medical imaging or cargo imaging.
