  6. Packet Loss Dell Inspiron, WinLAB 2.6.35 kernel, Intel 6250 chip, Omni BS antenna

  7. WiMAX Mobile Stations • Beceem • Linux • Android/EVO

  8. Windows XP + Beceem Dongle • Nice, works out of the box • .profile encrypted • Fair sensitivity • Ran with cygwin • Shell scripts • Thrp tests

  9. Dell Inspiron + Linux Wireless • WinLAB kernel • BBN GDB • wimaxcu • wimaxll

  10. HTC EVO Android 4G • Android OS • “locked” vs “unlocked” • Unlock and install 2.1 • Find profile & freq tables, replace with GENI

  11. Test suite additions ASNGW IDU rssi TCP,UDP iperf iperf ODU + GPS location + spectrum analyzer + better understanding of /var/log/wimax_kernel_info + visibility into per-MS stats
