It is an unavoidable fact that machine learning (ML) hardware architectures are evolving rapidly. Initially most visible in datacenters (many hyperscalars have built their own AI chips), the trend is now red-hot in inference engines for the edge, each spinning new ground-breaking methods. Markets demand these advances to … Read More

5G and Aircraft Safety: Simulation is Key to Ensuring Passenger Safety – Part 4
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
5G and Aircraft Safety: Simulation is Key to Ensuring Passenger Safety – Part 3
In our previous blog installment, we introduced the components of RF interference modeling, and established models for wideband peak emissions of a 5G C-band transmitter and the wideband receiver susceptibility for a radar altimeter receiver. Here, we consider the third component: the wireless channel, which considers the… Read More
5G and Aircraft Safety: Simulation is Key to Ensuring Passenger Safety – Part 2
In our first blog installment, we outlined the interference concerns surrounding the coexistence of the new C-band 5G telecom service spanning the band from 3.7 to 3.98 GHz with aviation radar altimeters. Radar altimeters are essential components for safety during landing and takeoff, as they offer precise measurements from… Read More
5G and Aircraft Safety: Simulation is Key to Ensuring Passenger Safety
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
5G Requires Rethinking Deployment Strategies
5G’s Departure from Its Predecessors
In each move from 1G to 4G people became accustomed to seeing the new generation as primarily offering increased bandwidth and efficiency. It would be a mistake to view the transition to 5G along these same lines. 5G takes Radio Area Networks (RANs) from a use model primarily for cell phone communications… Read More
The Clash Between 5G and Airline Safety
For 5G to really deliver on its promise of high bandwidth and good coverage, it needs to use an RF band known as C-Band (3.7 to 4.4 GHz). This band is ideal because its frequency is high enough to offer 100MHz wide channels and also low enough that signal attenuation, especially in urban areas, is minimal. In 2020 the FCC auctioned off… Read More
How France’s Largest Semiconductor Company Got Stolen in Plain Sight
Originally published on Fabricated Knowledge
Soitec is a semiconductor materials company known for its smart cut and Silicon on Insulator (SOI) technologies, which are critical in 5G, Silicon Photonics, and Silicon Carbide (EV) end-markets.
Yesterday, they announced that current CEO Paul Boudre will retire and be replaced… Read More
The 5G Rollout Safety Controversy
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
