=== Sandbox 1 (sb1.cosmos-lab.org) ===

COSMOS sandbox 1, located at [https://www.winlab.rutgers.edu WINLAB's]  [https://www.orbit-lab.org 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.

{{{#!box note width=600px
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:

  [[Image(mmwave-rf-block-diagram.png, 500px)]]

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 X310 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 X310 =||= Sivers Array=||
 ||  TX_A  ||  TX-I  ||
 ||  TX_B  ||  TX-Q  ||
 ||  RX_A  ||  RX-I  ||
 ||  RX_B  ||  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  ||
 ||  DAC229_T1_CH3  ||  TX-Q  ||
 ||  ADC224_T0_CH0  ||  RX-I  ||
 ||  ADC224_T0_CH1  ||  RX-Q  ||
