The 5G opportunity is truly game changing. In the 5G era, advanced communication systems will deliver new entertainment experiences, serve as the backbone of intelligent autonomous mobility, revolutionise healthcare and propel manufacturing into a new era of smart connected factories and products. Engineering teams are key to unlocking this enormous potential. Ansys is a company that focuses on engineering simulation with the belief that it is a critical capability for building out the entire 5G ecosystem – from base stations to internet backbone and data centres. In an interview with tele.net, Shital kumar Joshi, technical director, electrical and electronics – India, Ansys, talks about the company’s key focus areas and the ever-evolving 5G ecosystem…
What are Ansys’ focus areas in helping develop and deploy 5G systems?
Ansys is supporting 5G leaders in their journey of deploying virtual product development, verification and validation approaches to achieve following critical factors:
- Scalability and user density
- Broadband user experience
- Reliability and security
- Edge capabilities
- Spectral efficiency
What are the best practices for developing reliable 5G solutions?
Communication systems are evolving as technology grows. There are three areas on which technologists are focusing to implement practices for developing reliable 5G systems. These are:
- Design development of chip package systems and signal integrity (SI)/ power integrity (PI) analysis of high bit rate systems: Technologies are evolving to provide high data rate transmission with the minimum number of design cycles. A robust SI/PI analysis provides flexibility in designing and analysing digital high-speed board designs and optimising them for the best possible parameters (data rate, bit error rate).
- Radio frequency (RF) systems, antennas, RF interference and electromagnetic interference analysis: Designing of multi-band/multi-antenna elements with beamforming and massive multiple input multiple output implementations in a compact and loaded platform, interference between antennas and circuitry, cable susceptibility to the environment and channel modelling are the challenges that have been identified in the RF design of 5G, for which a comprehensive simulation-based approach is being used by the industry.
- Multiphysics analysis of 5G systems: A comprehensive multiphysics study can help mitigate the risks of failure and contribute towards robust system design. In summary, integrated multi-scale multi-domain and multiphysics simulations are being deployed to ensure the reliable performance of 5G networks.
What are the reliability, power and other issues faced while developing these solutions?
Simulation allows the early analysis of chip power consumption, leading to unprecedented efficiency and first-pass design scenarios.
Apart from reliability and power issues, environmental effects, wind loading, solar loading, etc. are the challenges that are dealt with via Ansys capabilities such as EM-thermal-mechanical coupled simulation workflows, thermal stress, mechanical deformation simulations and integration of chip-level workflows with package/board/ system-level multiphysics workflows.
What are the implications of 5G for internet of things (IoT) and smart connected products?
5G deployment will take place in phases. Significant economic and social value can be generated by enabling use cases activated by 5G. Functional drivers such as ultra-low latency, intelligent machines, edge computing, high processing and power will enable use cases. A few critical ones are:
- 5G technology will enable healthcare systems to provide improved remote monitoring for patients.
- Enhanced agricultural productivity enabled by IoT-based real-time data gathering, analytics and decision-making.
- The important functions include vehicle-to-vehicle communication, where vehicles transmit signals to each other, and vehicle-to-infrastructure communication, where vehicles communicate with sensors present on roads, traffic lights and bridges.
- Smart factories will be filled with sensors that will monitor different aspects of production.
- Smarter government management and services under smart cities.
In sum, the development of these next-generation 5G communication systems is a complex proposition. The multiscale, multidomain and multiphysics approach with our open ecosystem continues to enable seamless integration of Ansys software in existing platforms for design, development and testing of 5G systems.
