Seeing good throughput (up to 14Mb/s DL and 1 - 2 Mb/s UL) 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.

(GEC10, or earlier) Evaluate range and thoughput of WiMAX base station kit and Linux PC with Intel WiMAX modem card and/or mobile station used for for experiments. (GEC10, or earlier) (GEC11) Install and bring up an instance of OMF/OML. (GEC10, or earlier) (*GEC11) Operate and maintain the WiMax BS and the related GENI controller, using ORBIT Management Framework (OMF), with support for remote access by GENI users. (GEC11) Present a mobility demo using WiMAX base station node, including the ASN Gateway, a Linux PC with Intel WiMAX modem card, or the dual-mode vehicular nodes, supporting both WiFi and WiMAX, required for your experiments, and a local instance of OMF/OML. (GEC10) (*GEC11) Install and bring up experiment-controlled L2 (or OpenFlow) switch, to provide enhanced connectivity from the WiMAX testbed to the GENI backbone. (GEC11) (*GEC12) Install and bring up Virtual Base Station (vBS)server, to support multiple simultaneous experiments (slicing) on the GENI WiMAX base station node. (GEC11) (*?) Present mobility and/or application demos/experiments, showing support for multiple simultaneous experiments (slicing) of the GENI WiMAX base station node, and remote access by GENI users, utilizing experiment-controlled L2 (or OpenFlow) switch, and Virtual Base Station (vBS) server.
