= Xilinx ETS 2014 Demo: Massive MIMO Wi-Fi Channel Characterization =

The Rice Argos ([http://argos.rice.edu http://argos.rice.edu]) team partnered with [http://mangocomm.com Mango Communications] to present a Massive MIMO Wi-Fi Channel Characterization demo at the Xilinx Emerging Technology Symposium 2014. This demo combines the [http://argos.rice.edu/pubs/Shepard-MobiCom13-Demo.pdf Rice Argos v2 massive MIMO testbed] with the [wiki:802.11 Mango 802.11 Reference Design] to capture and analyze channel estimates between the array and Wi-Fi clients in real-time.

The demo uses the 96-antenna Argos v2 array. The array is built around 24 quad-antenna WARP nodes, each node consisting of a [wiki:HardwareUsersGuides/WARPv3 WARP v3 kit and [wiki:HardwareUsersGuides/FMC-RF-2X245 FMC-RF-2X245 module]. Each node in the array runs the 802.11 Reference Design in receive-only mode. The array elements receive every Wi-Fi packet, decode the packet to identify the transmitting client, then report the client identity and the corresponding per-subcarrier channel estimates to a host PC for processing.
