Future Communication Technology for a Smart, Connected and Safe World

5G - the fifth generation cellular network standard - promises extremely fast communication, ultra-reliable low-latency links for real time communication and interaction, and support for huge numbers of connected devices in small areas. Beyond just providing faster internet access to more users, 5G will enable new technologies and new ways of doing business across industries, from enhanced smart manufacturing to safe autonomous driving and remote surgery.

Device manufacturers and network infrastructure providers have the challenging task of delivering the expected high performance in a short time, to cost, and without compromising compliance and safety standards. The technological challenges faced by companies investing in these areas are significant and many engineering problems remain unsolved. Ubiquitous communication links at sub-6 GHz and mm-wave frequency ranges will require the use of massive MIMO (multiple input multiple output) and antenna array technology both in wireless access points (e.g. small cell base stations) and user equipment like smartphones.

Adding support for 5G standards to already crowded compact devices places huge pressure on engineers to provide innovative high performance solutions that do not create electromagnetic compatibility or electromagnetic interference (EMC/EMI) issues like desense of other communication systems. Additional considerations, like designing for acceptable thermal performance of devices that are more densely packed, or allowing for the finer mechanical tolerances required of components operating at mm-wave frequencies, increase the need for well integrated multi-physics and multi-domain product design.

Accurate simulation, across physics and at all stages of the design process, from early concept exploration to virtual compliance testing, is essential. The extensive Dassault Systèmes SIMULIA portfolio of simulation technology, including mechanical, structural and stress analysis with Abaqus, electromagnetic simulation with CST Studio Suite, and other tools for thermal, fatigue and system simulation. Combined with the benefits of the 3DEXPERIENCE platform, they allow competitive products to be brought to market on time and on budget, despite the increased challenges posed by designing for 5G.
