 === Description ===
- A pair of Sivers EVK06002, evaluation kits for Sivers IMA TRX BF/01, are deployed on COSMOS SandBox1. TRX BF/01 is a 16+16 IEEE802.11ad Beamforming Transceiver with a complete Radio front-end, and it covers 57-66GHz.
+A pair of Sivers EVK06002s, evaluation kits for Sivers IMA TRX BF/01, are deployed on COSMOS SandBox1. TRX BF/01 is a 16+16 IEEE802.11ad Beamforming Transceiver with a complete Radio front-end with 57-66 GHz mmWave frequency range.
 
-Current deployment of COSMOS SB1 consists of 4 servers, 2 USRP N310s, 2 USRP 2974s and mmWave equipment, as shown in the following figure.  Nodes, srv1-lg1 and srv2-lg1 are directly connected (over USB, for JTAG programming) to USRP X310s sdr2-md2 and sdr2-md3 respectively. srv1-lg1 and srv2-lg1 also control the Sivers evaluation kits over USB.
-Channel sounding is the process of evaluating the characteristics of a radio environment. Evaluating the power delay profile (PDP) of a radio channel helps in developing statistical models for channel simulation.
+Current mmWave setup in COSMOS SB1 looks as shown in the figure below.

-This tutorial demonstrates how  to transmit and receive a signal using  a pair of Sivers 60GHz evaluation kits on COSMOS SB1.
+Baseband data samples to Sivers front-ends are fed by USRP X310s with BasicTX and BasicRX daughtercards. BasicTX (https://www.ettus.com/all-products/basictx/) daughtercard is a simple wideband (250MHz) interface to the raw DAC signals from USRP. Similarly BasicRX provides a simple, wideband interface to USRP ADCs. The raw data can be generated/processed in the FPGA on USRP X310 and can be transferred to the host servers srv1-lg1, srv2-lg1 over 10G Ethernet link for further processing/storage.
+Control software for Sivers front-ends runs on srv3-lg1 and srv4-lg1. srv3-lg1 is directly connected to Sivers SN0240 and srv4-lg1 is connected to Sivers SN0243. These servers also have a direct USB connection to the X310s, for JTAG programming.
 
+This tutorial demonstrates how  to transmit and receive a signal in the 60GHz mmWave spectrum using these Sivers front-ends.
