USRP

NITlab developed a Software Defined Radio (SDR) testbed that consists of 18 Universal Software Radio Peripheral (USRP) devices attached to the NITOS wireless nodes. USRPs allow the researcher to program a number of physical layer features (e.g. modulation), thereby enabling dedicated PHY layer or cross-layer research.

Initially, you have to reserve a node which features a USRP device. Here is a detailed list with the types of USRPs, nodes and types of connection that they have:

Testbed Node	USRP Type	Connnection Type
node052	N210	ETHERNET
node055	B210	USB 3.0
node056	B210	USB 3.0
node059	B210	USB 3.0
node060	B210	USB 3.0
node064	N210	ETHERNET
node067	B210	USB 3.0
node068	B210	USB 3.0
node071	B210	USB 3.0
node072	B210	USB 3.0
node080	N210	ETHERNET

Then you can start developing your work/experiments based on the image baseline_usrp.ndz

omf load -i baseline_usrp.ndz -t node0XX

In order to check the status of the USRP, login to the node0XX. If the node features a USRP N210 then setup the eth1 interface:

ifconfig eth1 192.168.10.1/24 up

and then run the following command:

uhd_usrp_probe

If the node features a USRP B210 then run the following commands:

usrp_status -a off
usrp_status -a on
uhd_usrp_probe
