    3535A major advantage of on-campus WiMAX (over using a regular cellular carrier) for experimentation, is that you can reconfigure the WiMAX BS. In this experiment, we'll try using WebRTC with and without link-layer retransmission (ARQ) and observe the effect of ARQ on latency, packet loss, and video rate.

     37To reconfigure a base station, you need to log on to the testbed console using SSH:
     38
     39{{{
     40ssh tutor01@witestlab.poly.edu
     41}}}
     42
     43From there, you can change base station settings using a simple HTTP command. For example, to turn on ARQ:
     44
     45{{{
     46wget -qO- "http://wimaxrf:5052/wimaxrf/bs/set?arq=1"
     47}}}
     48
     49
     50Most reconfigurations only take effect after a reboot:
     51
     52
     53{{{
     54wget -qO- "http://wimaxrf:5052/wimaxrf/bs/restart"
     55}}}
     56
     57You can see the full list of configurable options:
