¶ Sandbox 1 (sb1.cosmos-lab.org)
COSMOS sandbox 1, located at WINLAB's ORBIT facility in North Brunswick, NJ, 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.
Sandbox 1 resources:
- SDN Ethernet Switch
- Computing resources:
- High performance compute servers
- General purpose machines used for flashing/debugging of sandbox hardware
- Outdoor rooftop deployment:
- Pair of sub-6 GHz COSMOS nodes (one sector of a large COSMOS node and one medium node)
- Pair of InterDigital 60 GHz Edgelink nodes
- Indoor “benchtop” deployment:
- InterDigital 5G Performance (28 GHz) gNodeb and UE
- USRP X310, N310, and RFSoC based mmWave development setup that includes IBM 28 GHz PAAM, Interdigital MHU 28 GHz antenna array and 60 GHz development platform antennas that are mounted on an experimenter controlled movable platform.
- Mobile devices:
- USRP E312
- Intel NUC & USRP B205/B210 Based mobile nodes
Note:

The support servers in the two corners (srv1-in1, srv1-in2) and the server supporting mobile device development (srv1-in3) are not equipped with GPU or FPGA cards and are based on Intel Quad-Core I7 CPUs (as opposed to multi-core Xeon CPUs in core servers).

¶ RF Path Configurations for mmWave Development Platforms
The indoor mmWave development platforms are connected to the USRP's and SDR's as shown in the following example diagram:
To select a particular configuration, follow the instructions below for the specific setup you wish to use. It is possible to use multiple setups simultaneously as long as they do not conflict with respect to RF paths.
