| 116 | | Summary: [http://groups.geni.net/geni/attachment/wiki/GEC10WiMaxCampusDeployment/031711%20%20BBNWiMAXRangeThroughMeas.ppt slides] [[BR]] |
| 117 | | Description: Experiment uses script in mobile station and server behind base station to evaluate connection with ping and iperf. Seeing good throughput to 0.25 mi, but not yet further. Soon, will vary BTS and iperf parameters to see if can find a set for greater distances at lower rates. Do not expect range beyond 0.6mi. [[BR]] |
