    709 Overview of basic throughput experiment, using bidirectional iperf, both TCP and UDP  [[BR]]
    710   [http://groups.geni.net/geni/wiki/OMFWiMAXExperiments#GENIWiMAXExperimentsUsingOMFOML  Basic throughput experiment using OMF/OML]  [[BR]]
    711 
    712 The basic throughput experiments we have done utilize iperf, both TCP and UDP. [[BR]]
    713   In iperf, the data is generated in the client, and flows to the server. [[BR]]
    714   We put the client in the Mobile Station, and the server in the Base Station. [[BR]]
    715   We used -d dualtest (bidirectional mode), where test is initiated at the client, data begins to flow to the server, and then a second data flow starts at the server;  at the end of the test, results are available at the client. [[BR]]
    716   Because of this, all tests can be initiated at the Mobile Station, and then results are available there. [[BR]]
    717 
    718 iperf results in the TCP mode depend upon buffer sizes;  overall delay;  and lost packets.   [[BR]]
    719   Because of wireless propagation conditions, lost packets are common, and slight changes can significantly affect the measured throughput. [[BR]]
    720   Thus, TCP results are highly variable;  we took multiple measurements at each point, and identified the best and worst results. [[BR]]
    721   It would certainly be good to have a better way to evaluate available channel bandwidth. [[BR]]
    722   On the other hand, most apps use TCP and the variable results are typical of how these apps would see the channel. [[BR]]
    723 
    724 iperf results in the UDP mode, counts  % packets received, for a given (fixed) transmit rate. [[BR]]
    725   If the rate is set below the available bandwidth, typically 100% of the packets are received. [[BR]]
    726   If the rate is set above the available bandwidth, typically % of the packets are received typically equals available bandwidth divided by offered bandwidth, but there is no way to understand how many packets are actually lost. [[BR]]
    727   An extended test that ramped up the offered bandwidth in multiple tests, could actually verify the available bandwidth;  this could then be repeated to see real variations in available bandwidth. [[BR]]

    954 
    955  * Summary of discussions with Sprint about unlocked HTC Evo handset  [[BR]]
    956   * Must be unlocked by Sprint, so can register with GENI network  [BR]]
    957   * Perhaps:  500 handsets, purchased by Rutgers WINLAB, approx $500 per handset, and distributed to sites  [[BR]]
    958   * Harry reports:  waiting for 3-way NDA to be signed, so that we can resume discussions with Sprint  [[BR]]
    959   * Need to poll sites for interest  [[BR]]
    960 
    961 
    962  *  Also possible:  Sprint MVNO arrangement for pay-as-you-go data service  [[BR]]

    964   * Need to poll sites for interest   [[BR]]
    965 
    966  * Comments from Matt Sanders (Georgia Tech), who attended the WiMAX meeting  [[BR]]
    967   * Along with other jobs, he reports to the CTO, and is campus wireless services manager.    [[BR]]
    968   * He has extensive experience negotiating with carriers (and I believe Sprint).  [[BR]]
    969   * We talked for some time, and he agreed to advise us as we continue our discussions with Sprint.  [[BR]] 
    970 
    971  * His comments:  [[BR]]
    972   * 1)  Sprint has multiple approaches to dealing with “enterprise customers”.  One approach we might consider, for 3G/4G service: “Access Point Node”  (APN), where designated mobile stations (typically associated with an enterprise) are assigned certain IP addresses, so that their traffic can be routed directly to the enterprise. (This is likely to be in a different business unit that the MVNO approach)  [[BR]]
    973   * 2)  Matt has a contact at HTC.  He feels that they might well be willing to make a batch of Evos for us.  We would have to talk with them to understand the minimum quantity.
