    141 * Open transmit application TX_TEST.grc on transmit node(srv4-lg1). This application transmits 802.11ad frames over rfdev3-2(10.115.2.3), at 200MSPS, by reading samples from a pre-generated file.
    142 * Open receive application RADIORX_CIR.grc on receive node(srv3-lg1). This application receives and processes samples over rfdev3-1(10.115.2.2) as seen in the grc model below. Channel impulse response computed for every frame is written into a file on the host node.
