Aerial drones represent a new breed of mobile computing. Compared to mobile phones and connected cars that only opportunistically sense or communicate, aerial drones offer direct control over their movements. They can thus implement functionality that were previously beyond reach, such as collecting high-resolution imagery, exploring near-inaccessible areas, or inspecting remote areas to gather fine-grain environmental data.

Spectrum utilization has become increasingly fragmented and diverse, with millions of devices supporting multiple protocols and use cases. A smartphone today uses LTE, Bluetooth, and Wi-Fi simultaneously, spanning multiple GHz of spectrum. In such an environment, comprehensive knowledge of spectrum usage can help in ushering in better networked system design, unified control, and provide new ways of understanding cyber-physical interactions. A versatile spectrum sensor that can monitor all utilized bands quickly and at low cost is a crucial enabler for such applications. Such a sensor is difficult to realize due to the vast size of the terrestrial spectrum and the necessity to keep up with fleeting wireless communication signals in innumerable bands. Additionally, it needs to be inexpensive and suitable for mass deployment. We introduce a new paradigm, in which the spectrum sensor can "sweep" over a wide band of spectrum quickly and extract useful information, such as occupancy and protocol type. The system, dubbed SweepSense, is prototyped on inexpensive hardware and opens up opportunities for new applications that were previously intractable, even with expensive solutions.

A key challenge that has emerged in recent years is the ability to remotely monitor patients, particularly elderly individuals while they are at home. This is particularly important given demographic shifts; the WHO estimates that the global share of the population aged 65 years or over increased from 6 percent in 1990 to 9 percent in 2019, and is projected to increase to 16 percent in the next two decades [1]. While the increase in life expectancy is a tremendous achievement, it also presents a growing need to go beyond episodic measurement collected in clinical settings to continuous monitoring at home. Indeed, this issue has become particularly acute in recent times in light of the COVID-19 pandemic and the need to ensure timely treatment delivery while at the same time protecting elderly from exposure to the virus and alleviating burden on support staff.

Small-cell LTE and Wi-Fi networks are both currently deployed in the unlicensed 5 GHz bands globally, leading to the need for new coexistence regulations between two very different access technologies. 3GPP standardized LTE Licensed Assisted Access (LTE-LAA) addresses the above coexistence challenge with Wi-Fi through incorporation of similar sensing and back-off features. The success of LAA's fair and efficient coexistence with Wi-Fi can be considered a benchmark for collaborative cellular operation in unlicensed bands.

Edge computing is a trending notion introduced a decade ago as a new computing paradigm for interactive mobile applications. The initial vision of the edge was a multi-tenant resource that will be used opportunistically for low-latency mobile applications. Despite that vision, we see in practice a different set of applications, driven by large-scale enterprises that have emerged and are driving realworld edge deployments today. In these applications, the edge is the primary place of storage and computation and, if network conditions allow, the cloud is opportunistically used alongside. We show how these enterprise deployments are driving innovation in edge computing. Enterprise-driven scenarios have a different motivation for using the edge. Instead of latency, the primary factors are limited bandwidth and unreliability of the network link to the cloud. The enterprise deployment layout is also unique: on-premise, single-tenant edges with shared, redundant outbound links. These previously unexplored characteristics of enterprise-driven edge scenarios open up a number of unique and exciting future research challenges for our community.

A recent trend in the global mobile/IoT industry is the emergence of next-generation smart devices with various screens, thus mobile/IoT market leaders are highly focused on building a new multi-device computing ecosystem based on such new smart devices. Market leaders are not only simply varying their screen sizes, but also competitively launching new devices equipped with innovative screens like foldable and dual-screen phones. However, the current mobile computing ecosystem is restricted by the single device paradigm that allows a user to interact with only one screen tethered to a single device, limiting the potential that the emerging multi-device computing trend provides.

We have reached an important milestone in Automatic Speech Recognition (ASR) technology, with major industrial AI companies, such as Samsung, Google, Apple, and Amazon releasing high-quality ASR models that run completely on-device, e.g., on consumer smartphones. This is the consequence of giant strides in technological advancements: from making commercial grade ASR systems feasible; to large scale cloud deployments; to the present day state-of-the-art models that run on resource constrained devices.

Since their introduction to the consumer market in the 1970s, microwaves have seen widespread adoption and, today, they are the third most popular domestic food heating method (after baking and grilling). Indeed, the original patents for the microwave by Raytheon Inc. in the late 1940s envisioned a universal food cooking instrument for all kinds of food ranging from meat to fish [2]. While microwaves have revolutionized the kitchen since their inception, today's consumer microwaves are mainly used as a blunt heating instrument (e.g., reheating pizzas) rather than a precise cooking equipment (e.g. cooking steak). The potential of microwave cooking is limited by the fact that today's microwaves heat food blindly, resulting in a non-uniform and unpredictable heating distribution [3].

The knowledge of soil moisture and electrical conductivity (EC) is critical for a variety of agricultural applications. For example, precision irrigation, which refers to the variable application of water in different regions of the farm, depends on accurate soil moisture values at different depths. This technique helps reduce water use, and also reduces soil leaching and contamination of ground water by chemicals in fertilizers and other agricultural inputs. Soil EC is another key indicator of soil health. It has been shown to correlate very well with crop yield and plant nutrient availability, and the USDA recommends that farmers measure soil EC to determine soil treatment plans and management zones for Precision Agriculture [1].
