Future mobile and embedded systems will be smarter and more user-friendly. They will perceive the physical environment, understand human context, and interact with end-users in a human-like fashion. Daily objects will be capable of leveraging sensor data to perform complex estimation and recognition tasks, such as recognizing visual inputs, understanding voice commands, tracking objects, and interpreting human actions. This raises important research questions on how to endow low-end embedded and mobile devices with the appearance of intelligence despite their resource limitations.

Two distinct trends are apparent in the design and planning of satellite missions. Until the late 1990s, multibillion-dollar space programs centered on large satellites, such as Envisat [1], promised to provide a common platform to support a variety of co-located sensing equipment. A reduction in cost was expected, as several instruments shared a single bus and a single launch. These benefits did not materialize due to the rise of a plethora of engineering and scheduling problems: electromagnetic incompatibilities between diverse technologies; instruments inducing vibrations on the platform that affect other equipment; and deployment-ready instruments waiting for other equipment in earlier development stages. As a reaction to these issues, the second trend where programs based on single-instrument satellites of much smaller sizes and mass began to emerge, eventually leading to the deployment of space devices that nowadays we call small satellites [11].

As rocket launch cadences increase, access to space rises dramatically - setting the stage for the next space industry surge. New, smaller, and less expensive satellites - now "nanosatellites" - can be deployed en masse to form constellations of hundreds, thousands, or even tens of thousands of devices [27, 40, 41, 16, 17, 18, 43]. A constellation of nanosatellites equipped with sensors (e.g., visual or hyperspectral cameras, particle detectors, or magnetometers) and radios provides a first-time opportunity for orbital swarm sensing to synthesize data from the unique vantage point of low-Earth orbit (LEO).

Millimeter-wave (mmWave) technologies represent a cornerstone for emerging wireless network infrastructure, and for RF sensing systems in security, health, and automotive domains. However, the lack of an experimental platform has been impeding research in this field. In this article, we propose to fill the gap with M3 (M-Cube), the first mmWave massive MIMO software radio. M3 features a fully reconfigurable array of phased arrays, with up to 8 RF chains and 256 antenna elements. Despite the orders of magnitude larger antenna arrays, its cost is orders of magnitude lower, even when compared with state-of-the-art single RF chain mmWave software radios. Case studies have demonstrated the usefulness of M3 design for research in mmWave massive MIMO communication and sensing.

In this paper, we summarize the quantum mechanics that define quantum technologies (quantum states, superposition, entanglement, and decoherence), introduce modern quantum technologies and their broader applications (quantum computing, quantum communication, quantum cryptography, quantum internet, and quantum error correction), examine the state quantum technology standards, and discuss how quantum technologies relate to the mobile world. For decades, methods for quantum technologies have been theorized or proven mathematically. Real implementations of these methods exist in modern devices such as lasers and magnetic resonance imaging (MRI) scanners. However, the precise manipulation of quantum particles - the fundamentally probabilistic building blocks of our world - is still in its relative infancy, with technologies that depend on manipulation being usable but limited in either function or adoption.

There are more smartphones than people today and communication technologies powering these phones help us stay connected all over the world. Perhaps one of the most fundamental aspects for mobile communication is the ability to make phone calls on-the-go. We take this for granted today, but someone has built that technology for us. That someone is Marty Cooper, who invented the first handheld cellular phone - DynaTAC - back in 1973.

Millimeter-wave (mm-Wave) communications have become an integral part of WLAN standards and 5G mobile networks and, as application data rate requirements increase, more and more traffic will move to these very high frequency bands. Although there is an ample choice of powerful experimental platforms for sub-6 GHz research, building mm-Wave systems is much more difficult due to the very high hardware requirements. To address the lack of suitable experimentation platforms, we propose mm-FLEX, a flexible and modular open platform with real-time signal processing capabilities that supports a bandwidth of 2 GHz and is compatible with current mm-Wave standards. The platform is built around a fast FPGA processor and a 60 GHz phased antenna array at front-end that can be reconfigured at nanosecond timescales. Together with its ease of use, this turns the platform into a unique tool for research on beam training in highly mobile scenarios and full-bandwidth mm-Wave signal processing.

Amputation is always a devastating experience. In addition to the loss of function or sensation, the lowered body image leaves deeper emotional impacts on the victims and their loved ones. For various reasons, traumatic injuries and vascular diseases like diabetes [4] are common for particularly upper limb loss. According to the World Health Organization, there are more than 10 million people with hand amputations worldwide, 80% of whom are in developing countries. Unfortunately, only less than 3% have access to affordable prostheses [1-3]. Over the past few decades, there have been major advances in commercial prosthetic hands, enabling control over six degrees of freedom (flexion/extension in all five digits and thumb rotation).

Collaboration of batteryless devices is essential to their success in replacing traditional battery-based systems. Without significant energy storage, spatio-temporal fluctuations of ambient energy availability become critical for the correct functioning of these systems. We present Shepherd, a testbed for the batteryless Internet of Things (IoT) that can record and reproduce spatio-temporal characteristics of real energy environments to obtain insights into the challenges and opportunities of operating groups of batteryless sensor nodes.
