A Straightforward Way to "Broadcast" with Atheros-CSI-Tool

A Straightforward Way to "Broadcast" with Atheros-CSI-Tool

1. Start the Hostapd at the transmitter.

	  $ cd ~/Atheros/Atheros-CSI-Tool-UserSpaceAPP/hostapd-2.5/hostapd/
	  $ sudo ./start_hostapd.sh
	  
2. Connecting multiple receivers to the transmitter.
3. Modify MAC addresses of wireless NICs of the receivers to a common address.

	  $ sudo ifconfig ifName down
	  $ sudo ifconfig ifName hw ether newMac
	  $ sudo ifconfig ifName up
	  
4. Run send_data at the transmitter.

	  $ sudo ./send_data ifName newMac nPkt
	  
4. Run recv_csi at the receivers.

	  $ sudo ./recv_csi logFileName
	  
Now all receivers log CSIs of almost the same packets, just like broadcast!
