To establish a truly connected planet we need ubiquitous coverage for massive IoT deployments. The only way to do this practically is to complement terrestrial networks with satellite connectivity. As a result, there is an accelerating race to space and the IoT is undergoing a shift in scale as it moves to global low-power connectivity via satellites.

In some ways, today, theatre engineers work in more demanding conditions than manufacturing engineers. Everything has to be right on the night in theatres, harmonic corruption is at stratospheric levels, there can be major changes at a moment’s notice, and people run through the ‘machinery’ without a thought for personal safety, among the many other challenges.

Capturing data from machines and analysing it to discover trends can give greater knowledge of production processes, better insights into maintenance status, improved product quality and reduced energy use, is allowing manufacturing companies to take a …

The shift from cloud to edge computing has changed the sensor node concept, from using a simple DSP near the sensor, to applying deep neural networks functionality at the sensor level. Hence, most recent trends in this field have targeted device energy …

There are four steps to successfully cleaning printed circuit boards (PCBs): wet, scrub, rinse and dry. Wet the board with a pure cleaning fluid; scrub it using a good quality scrubbing brush; rinse it with more clean fluid; then, dry it. Typically the …

Function generator circuits generate different waveforms – sinusoidal, triangular and rectangular. Such a circuit can generate just one type of signal or multiple waveforms. Here we will examine a popular function generator’s (Figure 1) behaviour and p …

BT has turned to atoms to deliver over 100x greater sensitivity in 5G receiver antennas compared to traditional receivers. The pioneering trial of a new hyper-sensitive quantum antenna is using excited atomic states to significantly boost the capabilit …

Researchers at Bangor University’s Digital Signal Processing (DSP) Centre have found a cost-effective way to improve the performance of networks which supply mobile services and broadband, but in a much kinder way to the planet. Because of the techniqu …
