While millimeter-wave (mmWave) wireless has recently gained tremendous attention with the transition to 5G, developing a broadly accessible experimental infrastructure will allow the research community to make significant progress in this area. Hence, ...

The rural US includes 72% of the nation's land and 46 million people, and it serves as major sources of food and energy for the nation. Thus rural prosperity is essential to US wellbeing. As a foundation for next-generation rural economy and communities,...

Much like earlier "network softwarization" efforts, the Open RAN concept is poised to have a transformative impact on the manner in which radio access networks (RANs) are realized and operated. The inherent complexity of the RAN ecosystem and the fact ...

Wireless Unmanned Aerial Vehicles (UAVs) were introduced in the world of 4th generation networks (4G) as cellular users, and have attracted the interest of the wireless community ever since. In 5G, UAVs operate also as flying Base Stations providing ...

Extensive use of unmanned aerial vehicles (UAVs) is expected to raise privacy and security concerns among individuals and communities. In this context, detection and localization of UAVs will be critical for maintaining safe and secure airspace in the ...

Mobility management is the key feature of cellular networks. When integrating unmanned aerial vehicles (UAVs) into cellular networks, their cell association needs to be carefully managed for coexistence with other cellular users. UAVs move in three ...

Channel state information (CSI) is paramount to modern Wi-Fi communication systems, as it allows for proper equalization of frames at the receiver side and enables advanced signal processing techniques such as beamforming and MIMO. Given that the CSI ...

The well-known susceptibility of millimeter wave links to human blockage and client mobility has recently motivated researchers to propose approaches that leverage both 802.11ad radios (operating in the 60 GHz band) and legacy 802.11ac radios (operating ...

Cellular operators have begun deploying 5G New Radio (NR) in all available bands: low (< 1 GHz), mid (1-6 GHz), and high (> 24 GHz) to exploit the different capabilities of each. At the same time, traditional 4G Long Term Evolution (LTE) deployments are ...

Security vulnerabilities make the Internet of Things (IoT) systems open to online attacks that threaten both their operation and user privacy. Among the many protocols governing IoT operation, MQTT has seen wide adoption, but comes with rudimentary ...

This paper describes a wireless experimentation framework for studying dynamic spectrum access mechanisms and an experiment that showcases its capabilities. The framework was built on COSMOS, an advanced wireless testbed designed to support real-world ...

As evolving wireless network architectures become more diverse, complex, and interdependent, and equipment costs prohibit broad access to such networks, remotely accessible experimental testbeds are gaining interest in recent years in wireless ...
