{{{#!box information
'''Important Information for COSMOS Users'''

Due to construction work being done at the Columbia University location, the ability to transmit from the SDRs in ''s1-lg1.bed.cosmos-lab.org'' and ''s2-lg1.bed.cosmos-lab.org'' is disabled until November 2020. Receiving on these nodes and all other functionality are still permitted. However, due to protection installed over the antennas, receive signal strength will be heavily attenuated.

These transmit restrictions do not affect ''s3-lg1.bed.cosmos-lab.org'', ''md1.bed.cosmos-lab.org'', ''md2.bed.cosmos-lab.org'', or any nodes in ''sb1.cosmos-lab.org'' and ''sb2.cosmos-lab.org''.

The **COSMOS** (**C**loud enhanced **O**pen **S**oftware defined **MO**bile wireless testbed for city-**S**cale 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 Funding

COSMOS is a joint project involving [https://www.rutgers.edu Rutgers], [https://www.columbia.edu Columbia], and [https://www.nyu.edu  NYU] along with [https://www1.nyc.gov/assets/cto/#/ New York City], [https://www.ccny.cuny.edu City College of New York], [https://www.siliconharlem.com Silicon Harlem], [https://www.arizona.edu University of Arizona] and [https://www.research.ibm.com IBM].

It is funded by the [https://www.nsf.gov National Science Foundation (NSF)] [https://advancedwireless.org/ Platforms for Advanced Wireless Research (PAWR)] program.

=== Deployment

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.
