NYU WIRELESS researchers continue to push the understanding of wireless networks in an end-to-end perspective. Our faculty and students share expertise in fundamentals, ranging from radio channel propagation and antennas, circuits, networking, MAC and PHY layers, as well as expertise in fundamental areas of the network and application layer.

Many NYU WIRELESS Initiatives focus on these areas, including open source software such as NYUSIM (now in use by over 75, 000 engineers who need realistic radio wave channel models from mmWave and THz ranges), and ns3 (where end-to-end 4G and 5G networks may be simulated in an open source manner), circuit device fabrication of quantum circuits, as well as the elaborate COSMOS experimental prototyping platform that is operating in New York City.

COSMOS (cloud enhanced open and software-defined mobile wireless), is one of the first national testbeds awarded by the National Science Foundation (NSF) through the PAWR (Plaform for Advanced Wireless Access). We are building an operational experimental mmWave outdoor network in the upper west side, covering many blocks. This is a major hardware-intensive network, that uses software-defined networking, and is available to our NYU WIRELESS Industrial Affiliates and other researchers interested in testing and proving their concepts for 5G, 6G and beyond.

COSMOS is led by Rutgers WINLAB, Columbia University, and NYU WIRELESS, which is responsible for the millimeter wave network component.

NYU WIRELESS’ participation in COSMOS comes after five more than five years of pioneering work in the area of millimeter wave communication that led to 5G.

While NYU WIRELESS has pioneered research that has expanded the RF bandwidth and Carrier Frequency of mobile communications, while reducing communcations latency, the novel contribution that COSMOS brings is the addition of a third dimension of improvement to future wireless networks: computing. Bringing computing to the edge of the network, to the base stations themselves, and closer to the edge than traditional wireless, will lead to vast new capabilities in wireless networking applications. Whether it be mobile edge computing, autonomous driving, or cloud-based vision systems, the research teams in COSMOS platform will study these three dimensions and are providing a unique test bed to experiment with how these may interact with one another.

The COSMOS program is one of the most ambitious test beds in U.S. universities today. It’s going to be 20 blocks of wireless area in the northern Manhattan, Columbia University area. COSMOS will compose around about a hundred nodes. Many of those nodes will be equipped with the latest cellular and wireless LAN technology, including vast fiber optic connections to COSMOS cell sites.

The COSMOS platform will be open source and will allow both universities and industries to experiment with the advanced technologies of the future.

Growing interest in mmWave communications has generated significant interest in open-source platforms for experimentation and validation of these systems that can be used by both academic and industrial research groups. However, designing mmWave experimental platforms is extremely challenging. The enormous data rates and requirements for very low latencies require platforms with very high computational power and highly-optimized data flows. Also, since the mmWave systems are in development, considerable customizability and flexibility is required. The goal of this project is to develop open-source platforms that can help researchers bring mmWave concepts to reality.
