Ka-band in satellite communications plays an increasing important role today. However, at higher frequencies, electromagnetic wave absorption increases. At Ka-band frequencies this can lead to service interruptions and performance degradation during rain fades. With high atmospheric losses, conventional fade margin approaches such as adaptive-waveform techniques or adaptive-power control techniques are not sufficient for compensation. For reliable and highly available operations, only site diversity configurations on the ground provide an adequate, fail safe solutions.

There is a wide range of SDRs, from basic to highly complex, that serve a multitude of purposes for a range of applications, that are still being uncovered. Read this article about the various factors for SDR performance and example applications.

Instead of the manpower and weapons that dominated the battlefield of the past, today’s powers vie for superiority in the electromagnetic spectrum. Deployment of this technology often requires a physical vehicle like a drone.

Read this review of the various test solutions offered today for mmWave semiconductor development and testing. Companies covered include Anritsu, Focus, FormFactor, Keysight, Maury, NI, R&S, Roos and Teradyne.

To ensure a fast and economic development of the new generation of IoT devices, module and chip makers have created a number of prototyping kits, developing platforms and reference designs that makes sure that any IoT engineer has everything ready to create an unlimited number of applications just bounded by imagination. From chipset, to sensors and embedded antennas, those IoT open hardware platforms have everything ready to create the newest IoT device in a jiffy.

Most Tier-1 and Tier-2 radar manufacturers such as Veoneer (Autoliv), Bosch, Continental, Delphi, Valeo, etc., are developing new automotive radars to overcome new challenges with autonomy. Most major players do not like to disclose what they are currently developing. Therefore, we can only discuss their existing sensors. On the contrary, startups usually do not hesitate to tell us much more about their products. This article highlights some of the major improvements we are likely to see in future radars covering the new startups.
