     A: Nodes are synchronized with the NTP server at boot time. However, once the testing starts the nodes can only talk to the packet server service over the Ethernet and thus NTP synchronization can't be maintained. 
  1. Q:'''How is noise being added to the environment?''' '''What is meant by: "received SNR might range from 0dB SNR to 10dB"?''' [[BR]]
-    A: Real noise is being injected into the environment (i.e. affecting both ends of the link). The injected noise level will be adjusted so that SNR measured by the receiver varies from 0 dB to 10 dB when transmitter is transmitting at the maximum power (100 mW for SBX front-end) and will not be adaptive.
+    A: Real noise is being injected into the environment (i.e. affecting both ends of the link). The injected noise level will be adjusted so that SNR measured by the receiver will be somewhere between 0-10 dB when the transmitter is transmitting at the maximum power (100 mW for SBX front-end). Further, the noise level will be fixed for all time slots that include interference, i.e., N1 and N2 slots.
  1. Q: '''How is 2.5 MHz bandwidth measured?''' [[BR]]
     A: It is a 3 dB bandwidth (of 2.5 MHz max).
