COSMOS Testbed Overview

The COSMOS (Cloud enhanced Open Software defined MObile wireless testbed for city-Scale deployment) project is aimed at design, development and deployment of an advanced wireless city-scale testbed in order to support real-world experimentation on next-generation wireless technologies and applications.

Participants and Supporters

COSMOS is a joint project involving Rutgers, Columbia, and NYU along with New York City, City College of New York, Silicon Harlem, University of Arizona and IBM.

It is supported by the National Science Foundation (NSF) Platforms for Advanced Wireless Research (PAWR) program.


The COSMOS testbed is being deployed in West Harlem, New York City with technical focus on ultra-high-bandwidth and low-latency wireless communications with tightly coupled edge computing, and emphasis on the millimeter-wave (mmWave) radio communications and dynamic optical switching.

New Users should sign up using the User Registration Form, but please check to make sure you are signing up under the correct organization, as only the selected group's admin will see your request.

Organizations must list a primary contact, who will be responsible for approving individual memberships in that group. In addition, they are responsible for the conduct of their members. They can be registered at the Organization Registration Form


Since the testbed can radiate in a wide range of RF frequencies, and uses a considerable amount of power and other resources, we require that it be used for legitimate research purposes.

Efforts have been made to prevent accidental misuse or interference with other users or the public, however deliberate abusive or malicious actions will result in a ban from access.

Accidents, mistakes, misconfigurations and the like happen. Some actions, such as transmitting on a forbidden frequency, or accidental network denial of service, will result in a warning to you, and your group administrator.

This is a shared resource, please make every effort to be considerate to other users.

Getting Started

For first-time users please refer to the COSMOS work flow process page. There are a few steps involved so this is meant to be used as a guideline.

Time based reservation can be made at the Control Panel.

From that page, under "Manage my account" is a link to upload a ssh public-key. Configure your client to use the corresponding private key for access.

During your reservation, your SSH keys will be enabled at

The naming convention for devices and networks is described at naming
