[[BR]] For 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]] WINLAB has a frim quote from Airspan for their MacroMAXe profile-C WiMAX base station unit, and related items.

[[BR]] e) It is expected that additional base stations kits will be purchased for some (or all) Sol 3 GENI sites in Spiral 5. [[BR]] Thus, campus site might be able to add additional sectors, at no cost. [[BR]] Planning for next year will be done later this year. [[BR]] Consider including additional sectors within your technical plan right away. [[BR]] f) Note: Airspan indicates that they expect to introduce a new base station unit within the next year. [[BR]] Somewhat reduced performance/range. [[BR]] Approximately half the cost [[BR]] g) Airspan indicates that their sector antenna provides:[[BR]] A 90degree pattern, which is consistent with proper coverage over a 120degree sector.[[BR]] Four internal elements, to support 2x4 MIMO.[[BR]] Airspan can provide provide x4 omni-directional antennas, but the cost is much higher, and the range is signifcantly reduced.[[BR]] h) 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]] 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]] 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]] [http://groups.geni.net/geni/attachment/wiki/GEC12WiMaxDeploymentAndExperimentation/CS%20Network%20Configuration%20Setup%20Guide.pdf MacroMAXe Configuration Guide][[BR]] i) Airspan shows that if handover operation is desired, an ASN GW must be provided, plus typically an associated RADIUS (authentication) server.[[BR]] In this case, the base station unit operates with IP at the interface.

[[BR]] In iperf, the data is generated in the client, and flows to the server. [[BR]] We put the client in the Mobile Station, and the server in the Base Station. [[BR]] 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]] Because of this, all tests can be initiated at the Mobile Station, and then results are available there. [[BR]] iperf results in the TCP mode depend upon buffer sizes; overall delay; and lost packets. [[BR]] Because of wireless propagation conditions, lost packets are common, and slight changes can significantly affect the measured throughput. [[BR]] Thus, TCP results are highly variable; we took multiple measurements at each point, and identified the best and worst results. [[BR]] It would certainly be good to have a better way to evaluate available channel bandwidth. [[BR]] On the other hand, most apps use TCP and the variable results are typical of how these apps would see the channel. [[BR]] iperf results in the UDP mode, counts % packets received, for a given (fixed) transmit rate. [[BR]] If the rate is set below the available bandwidth, typically 100% of the packets are received. [[BR]] 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]] 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.
