     145
     146 * Our testbed nodes are scattered throughout several CS labs and research areas (not part of our group).  [[BR]]
     147  * They are connected to the pre-existing Ethernet jacks in the walls and floors of those rooms, which all go back to a CS server room, where we patch them through to our own (non-openflow) switch for the control network. [[BR]]
     148  * We do have an openflow switch that we plan to deploy somewhere at some point. [[BR]]

     211
     212 * Summary of discussions with Sprint about unlocked HTC Evo handset  [[BR]]
     213  * Must be unlocked by Sprint, so can register with GENI network  [BR]]
     214  * Perhaps:  500 handsets, purchased by Rutgers WINLAB, approx $500 per handset, and distributed to sites  [[BR]]
     215  * Harry reports:  waiting for 3-way NDA to be signed, so that we can resume discussions with Sprint  [[BR]]
     216  * Need to poll sites for interest  [[BR]]
     217
     218
     219 *  Also possible:  Sprint MVNO arrangement for pay-as-you-go data service  [[BR]]
     220  * Harry reports:  waiting for 3-way NDA to be signed, so that we can resume discussions with Sprint  [[BR]]
     221  * Need to poll sites for interest   [[BR]]
     222
     223 * Comments from Matt Sanders (Georgia Tech), who attended the WiMAX meeting  [[BR]]
     224  * Along with other jobs, he reports to the CTO, and is campus wireless services manager.    [[BR]]
     225  * He has extensive experience negotiating with carriers (and I believe Sprint).  [[BR]]
     226  * We talked for some time, and he agreed to advise us as we continue our discussions with Sprint.  [[BR]] 
     227
     228 * His comments:  [[BR]]
     229  * 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]]
     230  * 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.

     613a)  Choice of Airspan to provide a WiMAX base station for new GENI WiMAX sites [[BR]]
     614NEC is not able to provide a WiMAX base station for new GENI WiMAX sites [[BR]]
     615WINLAB and the GPO have decided to purchase base stations from Airspan, a commercial company pursuing target customers such as universities and small carriers. [[BR]]
     616For example, the Univ of Colorado at Boulder IT Dept has installed an Airspan system with 4 sectors, that covers the campus.  They have been pleased with Airspan. [[BR]]
     617WINLAB has a frim quote from Airspan for their MacroMAXe profile-C WiMAX base station unit, and related items. [[BR]]

     622
     623b)  Rutgers will provide a kit including: [[BR]]
     624Airspan MacroMAXe profile-C WiMAX base station unit, for outside mounting[[BR]]
     625  Choice of frequency:   [[BR]]
     626  (2510 Lo:  2496MHz to 2570MHz)   [[BR]]
     627  (2510 Mid:  2560MHz to 2630MHz)  [[BR]]
     628  (2510 Hi:  2620MHz to 2690MHz)  [[BR]]
     629  (3650: 3650MHz to 3700MHz)]  [[BR]]
     630
     631NOTE:  WINLAB needs to know frequency choices during November (or early December), so that they can place an order with Airspan for delivery late 2011 or early 2012!
     632
     633Sector antenna, with x4 RF jumper cables [[BR]]

     640c)  Campus will need to provide: [[BR]]
     641Pole for mounting [[BR]]
     642DC power supply (-48v, approx 300W) [[BR]]
     643Ethernet cable, from base station unit (outside) to testbed (inside);  consider copper (may be a problem with lightning surge) or fiber (requires MM fiber cable, and fiber interface on switch) [[BR]]
     644Windows server to host network management software [[BR]]
     645Linux server to host OMF software [[BR]]
     646Ethernet switches, and other network equipment, for access (configuration to be provided) [[BR]]       
     647
     648d)  Additional kits can be purchased from Airspan [[BR]]
     649  Price is approximately $15,000. [[BR]]
     650 
     651e)  It is expected that additional base stations kits will be purchased for some (or all) Sol 3 GENI sites in Spiral 5. [[BR]]
     652  Thus, campus site might be able to add additional sectors, at no cost. [[BR]]
     653  Planning for next year will be done later this year. [[BR]]
     654  Consider including additional sectors within your technical plan right away.   [[BR]]
     655
     656f)  Note:  Airspan indicates that they expect to introduce a new base station unit within the next year. [[BR]]
     657  Somewhat reduced performance/range. [[BR]]
     658  Approximately half the cost [[BR]]
     659
     660g)  Airspan indicates that their sector antenna provides:[[BR]]
     661  A 90degree pattern, which is consistent with proper coverage over a 120degree sector.[[BR]]
     662  Four internal elements, to support 2x4 MIMO.[[BR]]
     663  Airspan can provide provide x4 omni-directional antennas, but the cost is much higher, and the range is signifcantly reduced.[[BR]]
     664
     665h)  Airspan shows that their profile-C base station unit can be configured to operate without an ASN GW and without a RADIUS (authentication) server.[[BR]]
     666  In this mode, a list of allowed base stations must be configured into the base station, and groups of these base stations are mapped to a VLAN on the ethernet port.[[BR]]
     667  This appears to be consistent with the current NEC base station unit operated with the ASN GW/WiMAX RF AggMgr code that has been provided by Rutgers/WINLAB[[BR]]
     668  [http://groups.geni.net/geni/attachment/wiki/GEC12WiMaxDeploymentAndExperimentation/CS%20Network%20Configuration%20Setup%20Guide.pdf  MacroMAXe Configuration Guide][[BR]]
     669
     670i)  Airspan shows that if handover operation is desired, an ASN GW must be provided, plus typically an associated RADIUS (authentication) server.[[BR]]
     671  In this case, the base station unit operates with IP at the interface.  [[BR]]

     742Overview of basic throughput experiment, using bidirectional iperf, both TCP and UDP  [[BR]]
     743  [http://groups.geni.net/geni/wiki/OMFWiMAXExperiments#GENIWiMAXExperimentsUsingOMFOML  Basic throughput experiment using OMF/OML]  [[BR]]
     744
     745The basic throughput experiments we have done utilize iperf, both TCP and UDP. [[BR]]
     746  In iperf, the data is generated in the client, and flows to the server. [[BR]]
     747  We put the client in the Mobile Station, and the server in the Base Station. [[BR]]
     748  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]]
     749  Because of this, all tests can be initiated at the Mobile Station, and then results are available there. [[BR]]
     750
     751iperf results in the TCP mode depend upon buffer sizes;  overall delay;  and lost packets.   [[BR]]
     752  Because of wireless propagation conditions, lost packets are common, and slight changes can significantly affect the measured throughput. [[BR]]
     753  Thus, TCP results are highly variable;  we took multiple measurements at each point, and identified the best and worst results. [[BR]]
     754  It would certainly be good to have a better way to evaluate available channel bandwidth. [[BR]]
     755  On the other hand, most apps use TCP and the variable results are typical of how these apps would see the channel. [[BR]]
     756
     757iperf results in the UDP mode, counts  % packets received, for a given (fixed) transmit rate. [[BR]]
     758  If the rate is set below the available bandwidth, typically 100% of the packets are received. [[BR]]
     759  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]]
     760  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]]
