In this work, we present MetaShield, a multi-function configurable metasurface that is affixed to and surrounds an Access Point (AP). We design MetaShield with three core features: (i) it is composed of configurable meta-atoms with subwavelength-scale ...

Rural broadband is critical to industries and community services such as precision agriculture, renewable energy, and rural education. Yet 39% of rural US and over 4 billion people around the world still lack broadband access. Addressing the challenge ...

Baseband processing is one of the most time-consuming and computationally expensive tasks in radio access networks (RANs), which is typically realized in dedicated hardware. The concept of virtualizing the RAN functions by moving their computation to ...

Efficient spectrum management is crucial for the Citizen Broadband Radio Service (CBRS), promoting shared radio frequency spectrum use. The US Federal Communications Commission (FCC) designated the frequency range of 3550 MHz to 3700 MHz for three types ...

Because of the ever-growing amount of wireless consumers, spectrum-sharing techniques have been increasingly common in the wireless ecosystem, with the main goal of avoiding harmful interference to coexisting communication systems. This is even more ...

As communications service providers ponder ways to cater to the diverse traffic requirements of mobile applications that range from the classic telephony to modern augmented reality (AR)-related use cases, the traditional quality of service (QoS)-based ...

In the never-ending pursuit of bandwidth, mid-bands have been recently reconsidered as the primary spectrum for 5G NR and its evolution. Laying between the crowded lower frequency bands and the propagation-unfriendly higher bands (i.e., millimeter wave), ...

The Federal Communications Commission (FCC) has allocated the 6 GHz band (5.925 - 7.125 GHz) for unlicensed, shared use in the US. Incumbents in the band are protected via Low Power Indoor (LPI) rules that do not require the use of an Automatic Frequency ...

The availability of datasets has been instrumental to drive advances in several disciplines like computer vision, image processing, and natural language processing. However, in the context of mobile traffic, data is often not available because of diverse ...

The adoption of Next-Generation cellular networks is rapidly increasing, together with their achievable throughput and their latency demands. Optimizing existing transport protocols for such networks is challenging, as the wireless channel becomes ...

MArena is an open-access underwater wireless testing platform based on the deployment of software-defined underwater modems at a semi-permanent marina location. Each reprogrammable and reconfigurable software-defined underwater modem is connected to a ...

The D11 is Broadcom's proprietary IEEE 802.11 MAC implementation and an essential part of their WiFi chips. It is a microcontroller that orchestrates the Physical Layer and Radio Front-end implementation and is programmable through a custom microcode. We ...

We see a trend toward serving Internet of Things (IoT) devices using the IEEE 802.11 protocol to offer cost-effective solutions. A WiFi AP serving simultaneously both broadband and IoT applications suffers from performance degradation as the slow IoT ...

Recently, researchers have shown that the beamforming feedback angles (BFAs) used for Wi-Fi multiple-input multiple-output (MIMO) operations can be effectively leveraged as a proxy of the channel frequency response (CFR) for different purposes. Examples ...
