= MERIF 2023 Cosmos Testbed Tutorial =

The purpose of this session is to provide an introduction to the COSMOS testbed with a hands on tutorial about basic usage of the testbed and a demonstration of a typical millimeter wave experiment.

The [https://cosmos-lab.org/ COSMOS testbed] is an NSF [https://advancedwireless.org/ PAWR] site deployed in New York City with a technical focus on ultra-high-bandwidth and low-latency wireless communications with tightly coupled edge computing, and emphasis on millimeter-wave (mmWave) radio communications and dynamic optical switching. The purpose of the testbed is to enable realistic at-scale experimental evaluation of new radio technologies, protocols and network architectures. The COSMOS testbed already supports at-scale experimentation of novel advanced wireless broadband and communication technologies in both sub-6 GHz and mmWave frequency bands in West Harlem in NYC, which is representative of a densely populated urban environment. The testbed provides a variety of fully programmable software-defined radio nodes for flexible wireless experimentation, along with heterogenous compute resources deployed in the datacenter and at the edge. It also includes a novel 100Gbps fiber backhaul interconnected with a software-defined network (SDN) switching fabric for minimum latency and flexibility in setting up experimental network topologies.

The remote accessibility of COSMOS lowers the barrier for experimentation in the area of next-generation communications technology and thus improves education and research productivity. Our hope is that this tutorial will allow members of the research community to try out the testbed and see its potential for use in their future research and educational activities. 

Prior to May 23, please follow these instructions so that you are able to use the testbed during the tutorial: [wiki:MERIF2023/SignupInstructions Signup Instructions]
