3. Parameter of the Command
March 2003
Parameter of the Command
MAC_add = transmitters MAC address
Band = a, b, g
Pktsize = size of data packets in octets
Num_cycles = number of cycles
Start_Ch = starting channel (1,..,11)
Num_Ch = number of channels to test
Mod = modulation to be used
Rate = time in ms between packets
Tx_Power_L = transmit power level

Display Statistics
Packet Success Rate per channel
RSSI; mean, max, min

How does it work?
Radio 1 requests Radio 2 to send him packets with the specified characteristics
Radio 1 is in receiving mode and collects statistics
Radio 2 is in transmit mode and sends packets
