With a tremendous increase in the number of connected devices and mobile data demand predicted over the next decade, the wireless communications industry is exploring new technologies to accommodate 5G wireless data systems, including MIMO (multiple-input, multiple-output) technology and millimeter wave frequency bands. One of the more complex environments for these technologies are urban small cells, where the prevalence of multipath and non-line-of-sight conditions leads to many challenges, particularly at higher frequencies.
Fixed Wireless Access (FWA) is one of the early planned use cases for 5G deployment, offering a new wireless alternative for providing broadband to homes and businesses. Because this requires very high bandwidth, many solutions for FWA consider use of new millimeter wave bands. This poses challenges for coverage, including increased path loss, weaker penetration through walls into the interiors of structures, and greater effects from shadowing of structures and trees on the outdoor propagation.
Antenna engineers favor advanced antenna systems capable of beam steering and multiple data stream transmission in order to meet 5G throughput requirements. Designing such a device is a difficult task because many factors are involved a device’s performance:
XFdtd and Wireless InSite ensure a comprehensive device design process, from simulating the initial antenna pattern to computing throughput performance in a multipath channel model. Together the products ensure a device will work well in its intended environment.
Precision is key when designing today’s complex mobile devices, and engineers can’t afford discrepancies between device efficiency and simulation results. Remcom users see less than a 0.5 dB difference in device efficiency when compared to simulation results. Importing the right CAD model achieves a higher level of accuracy with measurements that are exceptionally close to the real device, streamlining workflow and simplifying the design process.
5G is pushing the boundaries of wireless communications and wireless device design. Significant innovations are needed in order to accommodate increased requirements for Enhanced Mobile Broadband, Massive Machine-Type Communications, and Ultra-Reliable Low Latency Communications. To meet these challenges, the wireless industry is exploring new technologies, such as multiple-input, multiple-output (MIMO) and beamforming, higher frequency bands including millimeter waves, and a number of changes to how base stations and devices are deployed and used.
Remcom’s simulation products provide a complete solution, from system and antenna design through performance assessment in realistic, simulated environments, and planning for deployment in 5G networks. Our mission is to provide accurate solutions, optimized for performance to help our customers reliably predict how their systems will behave in the real world. Through active research and development, we have remained a leader in modeling and simulation technology for 5G and advanced wireless communications.
