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.

RF Path Configurations for mmWave Development Platforms

The indoor mmWave development platforms are connected to the USRP N310's and Xilinx RFSoC'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.

USRP N310 with Sivers 60 GHz Array

Run the following commands on the sb1.cosmos-lab.org console:

curl "am1.cosmos-lab.org:5054/rf_switch/set?name=rfsw1.sb1.cosmos-lab.org&switch=1,2,3,4&port=1"
curl "am1.cosmos-lab.org:5054/rf_switch/set?name=rfsw2.sb1.cosmos-lab.org&switch=1,2,3,4&port=1"

The resulting RF connections will be:

USRP N310 Sivers Array
RF0 TX TX-I
RF1 TX TX-Q
RF0 RX2 RX-I
RF1 RX2 RX-Q
Xilinx RFSoC ZCU111 with Sivers 60 GHz Array

Run the following commands on the sb1.cosmos-lab.org console:

curl "am1.cosmos-lab.org:5054/rf_switch/set?name=rfsw1.sb1.cosmos-lab.org&switch=1,2,3,4&port=2"
curl "am1.cosmos-lab.org:5054/rf_switch/set?name=rfsw2.sb1.cosmos-lab.org&switch=1,2,3,4&port=2"

The resulting RF connections will be:

Xilinx RFSoC Sivers Array
DAC229_T1_CH2 TX-I
