    34 Airspan/Rutgers will provide a kit including: [[BR]]
     34a)  Airspan/Rutgers will provide a kit including: [[BR]]
    3535Airspan MacroMAXe profile-C WiMAX base station unit, for outside mounting[[BR]]
    3636  Choice of frequency:   [[BR]]
     
    4545Network management software license, 1 per base station [[BR]]
    4646
    47 Campus will need to provide: [[BR]]
     47b)  Campus will need to provide: [[BR]]
    4848Pole for mounting [[BR]]
    4949DC power supply (-48v, approx 300W) [[BR]]
     
    5353Ethernet switches, and other network equipment, for access (configuration to be provided) [[BR]]       
    5454
    55 Additional kits can be purchased from Airspan [[BR]]
     55c)  Additional kits can be purchased from Airspan [[BR]]
    5656  Price is approximately $15,000. [[BR]]
    5757 
    58 It is expected that additional base stations kits can be purchased by GENI in Spiral 5. [[BR]]
     58d)  It is expected that additional base stations kits can be purchased by GENI in Spiral 5. [[BR]]
    5959  Thus, campus site might be able to add additional sectors, at no cost. [[BR]]
    6060  Planning for next year will be done later this year. [[BR]]
    6161  Consider including additional sectors within your technical plan right away.   [[BR]]
    6262
    63 Note:  Airspan indicates that they expect to introduce a new base station unit within the next year. [[BR]]
     63e)  Note:  Airspan indicates that they expect to introduce a new base station unit within the next year. [[BR]]
    6464  Somewhat reduced performance/range. [[BR]]
    6565  Approximately half the cost [[BR]]
     66
     67f)  Airspan indicates that their sector antenna provides:[[BR]]
     68  A 90degree pattern, which is consistent with proper coverage over a 120degree sector.[[BR]]
     69  Four internal elements, to support 2x4 MIMO.[[BR]]
     70  Airspan can provide provide x4 omni-directional antennas, but the cost is much higher, and the range is signifcantly reduced.[[BR]]
     71
     72g)  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]]
     73  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]]
     74  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]]
     75 
     76h)  Airspan shows that if handover operation is desired, an ASN GW must be provided, plus typically an associated RADIUS (authentication) server.[[BR]]
     77  In this case, the base station unit operates with IP at the interface.  [[BR]]
