Fig 11 KingCountyAirport Scenario STK Annotated

In our previous blog installments, we examined the ingredient for modeling the potential for interference between a 5G C-band base station and an aviation radar altimeter. Using candidate emissions models for the transmitter, wideband susceptibility models for a candidate radar altimeter receiver and antenna and propagation… Read More

Fig 1 Verizon Cov Map 5G UWB

The new 5G C-band service is now up and running in the U.S., and subscribers are finally starting to see some of the promise of 5G. The new C-band services are primarily in spectrum allocations between 3 and 4 GHz, providing the wider channel allocation bandwidths necessary to deliver significantly higher data throughput. At the… Read More

PCB

Automatic adaptive meshing in Ansys HFSS is a critical component of its finite element method (FEM) simulation process. Guided by Maxwell’s Equations, it efficiently refines a mesh to deliver a reliable solution, guaranteed. Engineers around the world count on this technology when designing cutting-edge electronic products.… Read More

Plane Landing

There has been a lot of attention in the news recently about AT&T and Verizon rolling out their first implementations of sub-6GHz 5G radio access networks (RAN). Notably, the FAA and airline industries have voiced serious concerns about potential safety issues for aircraft autopilot and landing systems. As a result of these… Read More


Can you Simulate me now? Ansys and Keysight Prototype in 5G

Can you Simulate me now? Ansys and Keysight Prototype in 5G
by Shawn Carpenter on 01-10-2022 at 10:00 am

5G Signal propagation

Ansys and Keysight wanted to see if they could answer the question, If we put virtual cellphones in different locations in a city, can we predict what kind of 5G signal we’re going to get in those locations? To find out, they created and tested a detailed virtual model of a city, including a variety of 5G antennae, receivers, and transmitters… Read More

I would contend there is no job quite like working as a support engineer for a simulation tool like Ansys HFSS. Such a role forces an engineer to understand technology in breadth and depth like no other because HFSS is applied to such a broad range of applications and products throughout the world. My own introduction to HFSS began … Read More
