PP2: Challenges and Opportunities of Implementing 6G Wireless Technologies in Real-World Scenarios


Malay Duggar, NI


6G research ideas are often based on theoretical models and assumptions that may not reflect the actual conditions and constraints of the real world.

By implementing 6G research ideas, we can also gain insights and feedback from the users and stakeholders, and identify the challenges and opportunities for improvement. It can also help demonstrate their potential impact and benefits for the society, and inspire further innovation and collaboration.

The research community is already exploring the possibilities of 6G, as 5G deployments are becoming more widespread and advanced. 6G will aim to achieve higher performance and enable new applications based on emerging technologies, as well as address the issues of sustainability and security. Some of the key technical areas that are being investigated for 6G are the integration of communications and sensing, the use of THz/sub-THz frequencies, the implementation of extreme MIMO, and the application of artificial intelligence/machine learning (AI/ML). These areas are complex and challenging, and require fast and efficient research and prototyping methods.

PP3: Accelerate R & D in 5G using NetSim


Pranav Viswanathan, NETSIM


Researchers lack the requisite tools for simulating end-to-end 5G networks. There are a few ‘Link-level’ simulators that enable users to model a single link between the UE and the gNB. These can’t be used for end-to-end modelling of the network, from the UE to the host-server. Furthermore, they do not allow for modelling of the entire TCP/IP protocol stack.

Open-source simulators are very complex, do not have a GUI, not easy to use, require the knowledge of various scripting & programming languages, and come with no support. Hardware testbeds that can be customized is prohibitively expensive.

NetSim solves these problems. It is an end-to-end, full stack, packet level simulator and features an easy-to-use GUI with simple drag and drop functionality. The output of the simulation is available as an appealing Results Dashboard with tables and graphs. The protocol source C codes are provided along with which can be modified by researchers to write their own algorithms/protocols. 

In this technical session, our focus is on the deployment and analysis of 5G networks using NetSim's simulation environment. The demonstration will encompass the following key areas:

  • 5G NR Network Architecture Configuration: Detailed walkthrough on setting up the 5G NR network within the NetSim User Interface (UI).
  • Protocol Stack Configuration: RRC, RLC, MAC, PHY, RF propagation
  • Output Performance Metrics: Presentation of graphical and tabular output metrics for performance analysis.
  • Diagnostic Logs:
    • PHY Radio measurements.
    • MAC Radio resource allocation
  • Trace Files:
    • Packet Trace: Analysis of packet-level data flow through the network.
    • Event Trace: Chronological sequence of simulation events for in-depth study.
  • Custom Code Integration in NetSim:
    • Guidelines for incorporating user-defined algorithms and protocols into NetSim's framework.
  • MATLAB Interfacing:
    • Procedures for coupling NetSim simulations with MATLAB for advanced computational tasks.

Simulation Parameters and Modelling Techniques:

  • MIMO and Beamforming: Implementation and impact on network performance.
  • Interference Modelling: Simulate and analyzing DL and UL interference in 5G networks.
  • Propagation Models: Rural Macro/Micro, Urban Micro/Macro, Line-of-Sight (LOS)/Non-Line-of-Sight (NLOS) scenarios
  • MAC Scheduling Algorithms: Analysis of different scheduling strategies and their influence on network performance.
  • Heterogeneous Network Modelling: Techniques for simulating multi-tier network architectures.
  • Handover Mechanism Modelling:
    • Parameter configuration: Offset, Time-to-Trigger (TTT).
    • Analysis of handover interruption times and their effects on user experience.

Each of these topics will be elucidated with relevant examples, highlighting NetSim's versatility in modelling complex 5G scenarios.

PP5: Channel modeling and measurements for 6G in the sub-THz and FR3 frequency range


Taro Eichler, Rohde & Schwarz


The frequency range of sub-terahertz and terahertz waves, which spans from 0.1 THz to 3 THz and falls between microwave and optical waves, holds significant potential for applications such as communication, imaging, spectroscopy, and sensing. With the ability to offer contiguous frequency bands and meet the demand for high data transfer rates of up to the terabit/sec range, this area of research is essential for 6G mobile communication. To fully utilize this potential, it is crucial to understand the propagation characteristics, and channel measurements are necessary for developing future communication standards. We will discuss the characteristics of channel modeling and propagation in this frequency range and present recent measurement campaign results in the D-band and H-band, including in industrial environments. Furthermore, we will discuss channel measurement results at 14 GHz in the so-called FR3 region, which has recently attracted interest as one of the potential bands for the initial 6G network roll-out.

PP6: Recent Progress In Optical Fiber Radiation Dosimetry


Hairul Azhar, Multimedia University, Malaysia


Ionizing radiation in the environment, medical, industrial, and high energy accelerator facilities have adverse effects on humans and installed electronics. Monitoring radiation levels across a facility and the environment requires an accurate radiation dosimetry which is distributed in nature. Likewise, accurate measurement of absorbed dose in radiotherapy and especially FLASH-RT is becoming crucial. Specialty optical fiber has demonstrated its potential as both passive and active radiation dosimetry in such scenarios. The coupled ability of specialty optical fiber as a sensor and as a waveguide opens a new dimension of distributed and point radiation sensing that is both in-situ, real-time and high-resolution based on radioluminescence (RL) and radiation induced attenuation (RIA). In this paper, we elucidate the recent progress in optical fiber radiation dosimetry focusing on time-resolved dosimetry leading to potential FLASH-RT dosimetry. Besides this, we report earlier work on industrial radiation measurement up to 70 kGy using optical fiber scintillators. Moving on to environmental monitoring, we report on recent work related to NORM and TENORM measurements using an extendable optical fiber probe radiation measurement system. Finally, we review suitable materials used in a specialty optical fiber for real-time and distributed radiation sensing based on Radiation Induced Attenuation (RIA). The concept of a real-time distributed optical fiber radiation dosimetry sensing system is introduced, focusing on the use of photobleaching in low-OH pure silica optical fiber and RIA based measurements using the optical time domain reflectometry (OTDR) technique
