    86   Range and capacity at BBN  (Tony Michel and Tom Cahill)  Testing with iperf;  reliable up to 0.25mi, rates from 1 to 13 Mb/s;  other times, won't connect, and ul seems to be the limit;  finally able to see some parameters in BTS, with WiMAX RF GS, showing WiMAX protocol adaptation.   [[BR]]
    87   Suman at Wisc:  Has done lots of drive tests, results consistent; Cisco 8-element array at BS;  Cisco desktop modem in vehicle, with patch antenna;  up to 1 mile.  [[BR]] Results to date.  Parameters to change seeking greater range.  [[BR]]

    8990  Range and capacity expectations   (Sampath Rangarajan)  Can NEC provide guidance on what to expect?  Can NEC verify/suggest parameters to change?  [[BR]]
    9091  Sampath:  If we provide data, he will query NEC in Japan.  [[BR]]
    91   Possible parameters to change:  HARQ;  pwoer level;  add 2nd ODU and antenna for MIMO.  [[BR]]
     92  Possible parameters to change:  HARQ;  power level;  add 2nd ODU and antenna for MIMO.  [[BR]]
