== mmWave Channel Sounding on SandBox1 (IN PROGRESS) == === Description === === Prerequisites === In order to access the test bed, create a reservation and have it approved by the reservation service. Access to the resources is granted after the reservation is confirmed. Please follow the process shown on [wiki:cosmos_workflow the COSMOS work flow page] to get started. === Resources required === 4 servers srv1-lg1 to srv4-lg1, 2 USRP X310s rfdev3-1, rfdev3-2 and both the Sivers platforms rfdev3-5, rfdev3-6 on COSMOS SB1. === Execution === ==== Prepare host nodes ==== * The image rfnoc_wigig.ndz has aforementioned RFNoC 802.11ad preamble processing blocks installed.
