Open Radio Access Network (O-RAN) brings a revolutionary approach to cellular RANs through its flexible and interoperable RAN architecture. It involves the separation of hardware and software components, allowing RAN vendors to subscribe to applications ...

With the ability to seamlessly integrate physical and virtual worlds to provide immersive experiences, Mobile Augmented Reality, is a promising technology for several futuristic applications such as on-the-job training and guidance in smart factories, ...

O-RAN, or Open-RAN, is a major revolution in mobile networks to promote an open system design for Radio Access Networks (RAN) subsystems [1]. Unlike traditional RAN with proprietary, single-vendor hardware, O-RAN separates RAN into multiple components, ...

Ultra-wideband (UWB) radios are gaining popularity following their inclusion in consumer devices such as Apple Watch and iPhone 15, as well as their inclusion in several innovative applications such as FIFA soccer balls, in cars to detect children and ...

5G networks have been broadly touted as a revolution in cellular performance. However, the practical realization of its capabilities remains challenging, particularly due to the interplay of multiple factors affecting performance. In this study, we ...

Cloud providers are embracing edge computing by developing multi-stakeholder clouds (MClouds), in which the infrastructure is shared among cloud providers, hosting site operators, and, sometimes, system integrators (Figure 1). The emergence of the MCloud ...

The next generation of cellular networks, driven by applications like large-scale autonomy, extended reality, and IoT-based control, demands high network performance in terms of throughput, latency, and jitter, along with quick network adaptability. ...

Video streaming is a dominant force in today's network landscape, representing 53% of total network traffic. This prominence makes it essential for Internet Service Providers (ISPs) to monitor the quality of experience (QoE) of video streaming for their ...

We demonstrate a device that plugs into the audio jack of a TV and broadcasts the audio over Wi-Fi. Nearby mobile devices can capture these Wi-Fi packets and extract the audio for playback on the user's earphones.

In our prior study [1], we have uncovered and characterize missed performance in operational cellular networks, namely, the performance gap between what user equipment (UE, say, mobile phones) actually gets and what it could have got at best, given the ...

Wireless community networks (WCNs) represent bottom-up network infrastructures facing the following challenges: (1) Managing diverse devices, (2) Establishing effective real-time incentives, (3) Addressing anomalies, attacks, and faults, and (4) Ensuring ...

Intracortical brain-computer interfaces (iBCIs) promise revolutionary clinical and research applications. State-of-the-art iBCIs rely on high-density (HD) microelectrode arrays (MEAs) to sense massive neuronal populations. However, HD MEAs are bandwidth-...

Jamming attacks pose a serious threat to the normal functioning of cellular networks, disrupting communication services and compromising emergency situations. This paper introduces BeamArmor, a practical real-time application to monitor and mitigate ...

5G and future 6G networks support diverse combinations of access technologies, architectures, and radio frequencies, with each combination termed as a "band" henceforth. Through comprehensive measurements in 12 cities across 5 countries, we ...

Simulating networks with mobile nodes requires implementing node movements according to mobility models and determining when which nodes can communicate. These computations grow with the number of nodes and may constitute a bottleneck when scaling up ...

In this work, we have conducted a measurement study with three US operators to reveal three types of problematic failure handling on secondary radio access which have not been reported before. Compared to primary radio access failures, secondary radio ...

Reconfigurable Intelligent Surfaces (RIS) is an emerging disruptive technology for next-generation wireless networks, which can achieve robust coverage in complex dynamic environments. However, current RIS designs are usually bulky and power-hungry, ...
