Sandbox 2 (sb2.cosmos-lab.org)

COSMOS sandbox 2, located at Columbia University in New York City, NY, is designed as a mini version representative of the current and future capabilities of the larger outdoor deployment in New York City. It is meant primarily to be a development and testing environment for researchers to become familiar with the software and hardware architectures available in COSMOS.

RF Frontend

Due to it's indoor deployment and its designated use being for development of future COSMOS capabilities, SB2 does not have the same RF frontend as the main testbed (ie. no amplification or filtering). Instead, only a set of RF switches is connected to most of the SDR's ports to give the experimenter the ability to connect to different future RF frontends or devices.

The configuration of the RF switches can be controlled via the rf_switch service's HTTP API. Use the following table as a reference for service parameters.
