     210=== R2 Airspan Profile-C Base Station, with Associated Hardware and Software ===
     211Ivan Seskar (WINLAB) and Harry Mussman (GPO) [[BR]]
     214a)  Choice of Airspan to provide a WiMAX base station for new GENI WiMAX sites [[BR]]
     215NEC is not able to provide a WiMAX base station for new GENI WiMAX sites [[BR]]
     216WINLAB and the GPO have decided to purchase base stations from Airspan, a commercial company pursuing target customers such as universities and small carriers. [[BR]]
     217For 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]]
     218WINLAB has a frim quote from Airspan for their MacroMAXe profile-C WiMAX base station unit, and related items. [[BR]]
     220[  Airspan brochure][[BR]]
     221[  MacroMAXe Product Specification]  [[BR]] 
     222[  Airspan Deployment Plan for Univ Colorado at Boulder][[BR]]
     224b)  Rutgers will provide a kit including: [[BR]]
     225Airspan MacroMAXe profile-C WiMAX base station unit, for outside mounting[[BR]]
     226  Choice of frequency:   [[BR]]
     227  (2510 Lo:  2496MHz to 2570MHz)   [[BR]]
     228  (2510 Mid:  2560MHz to 2630MHz)  [[BR]]
     229  (2510 Hi:  2620MHz to 2690MHz)  [[BR]]
     230  (3650: 3650MHz to 3700MHz)]  [[BR]]
     232NOTE:  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!
     234Sector antenna, with x4 RF jumper cables [[BR]]
     2352x4 MIMO, supported by base station and antenna [[BR]]

     242[[Image(AirspanMacroMAXe.jpg, 50%)]]  [[BR]]
     245c)  Campus will need to provide: [[BR]]
     246Pole for mounting [[BR]]
     247DC power supply (-48v, approx 300W) [[BR]]
     248Ethernet 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]]
     249Windows server to host network management software [[BR]]
     250Linux server to host OMF software [[BR]]
     251Ethernet switches, and other network equipment, for access (configuration to be provided) [[BR]]       
     253d)  Additional kits can be purchased from Airspan [[BR]]
     254  Price is approximately $15,000. [[BR]]
     256e)  It is expected that additional base stations kits will be purchased for some (or all) Sol 3 GENI sites in Spiral 5. [[BR]]
     257  Thus, campus site might be able to add additional sectors, at no cost. [[BR]]
     258  Planning for next year will be done later this year. [[BR]]
     259  Consider including additional sectors within your technical plan right away.   [[BR]]
     261f)  Note:  Airspan indicates that they expect to introduce a new base station unit within the next year. [[BR]]
     262  Somewhat reduced performance/range. [[BR]]
     263  Approximately half the cost [[BR]]
     265g)  Airspan indicates that their sector antenna provides:[[BR]]
     266  A 90degree pattern, which is consistent with proper coverage over a 120degree sector.[[BR]]
     267  Four internal elements, to support 2x4 MIMO.[[BR]]
     268  Airspan can provide provide x4 omni-directional antennas, but the cost is much higher, and the range is signifcantly reduced.[[BR]]
     270h)  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]]
     271  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]]
     272  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]]
     273  [  MacroMAXe Configuration Guide][[BR]]
     275i)  Airspan shows that if handover operation is desired, an ASN GW must be provided, plus typically an associated RADIUS (authentication) server.[[BR]]
     276  In this case, the base station unit operates with IP at the interface.  [[BR]]
     280=== 4.2)  Throughput Experiment Using iperf ===
     2812:15pm   [[BR]]
     282Manu Gosain (GPO) and Harry Mussman (GPO) [[BR]]
     284Overview of basic throughput experiment, using bidirectional iperf, both TCP and UDP  [[BR]]
     285  [  Basic throughput experiment using OMF/OML]  [[BR]]
     287The basic throughput experiments we have done utilize iperf, both TCP and UDP. [[BR]]
     288  In iperf, the data is generated in the client, and flows to the server. [[BR]]
     289  We put the client in the Mobile Station, and the server in the Base Station. [[BR]]
     290  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]]
     291  Because of this, all tests can be initiated at the Mobile Station, and then results are available there. [[BR]]
     293iperf results in the TCP mode depend upon buffer sizes;  overall delay;  and lost packets.   [[BR]]
     294  Because of wireless propagation conditions, lost packets are common, and slight changes can significantly affect the measured throughput. [[BR]]
     295  Thus, TCP results are highly variable;  we took multiple measurements at each point, and identified the best and worst results. [[BR]]
     296  It would certainly be good to have a better way to evaluate available channel bandwidth. [[BR]]
     297  On the other hand, most apps use TCP and the variable results are typical of how these apps would see the channel. [[BR]]
     299iperf results in the UDP mode, counts  % packets received, for a given (fixed) transmit rate. [[BR]]
     300  If the rate is set below the available bandwidth, typically 100% of the packets are received. [[BR]]
     301  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]]
     302  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]]
