     494  (3650: 3650MHz to 3700MHz)]  [[BR]]
     496NOTE:  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!
     498Sector antenna, with x4 RF jumper cables [[BR]]
     4992x4 MIMO, supported by base station and antenna [[BR]]
     500GPS antenna, with surge suppressor and cable [[BR]]
     501DC power cable, from base station unit (outside) to testbed (inside) [[BR]]
     502Network management software license, 1 per base station [[BR]]
     505c)  Campus will need to provide: [[BR]]
     506Pole for mounting [[BR]]
     507DC power supply (-48v, approx 300W) [[BR]]
     508Ethernet 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]]
     509Windows server to host network management software [[BR]]
     510Linux server to host OMF software [[BR]]
     511Ethernet switches, and other network equipment, for access (configuration to be provided) [[BR]]       
     513d)  Additional kits can be purchased from Airspan [[BR]]
     514  Price is approximately $15,000. [[BR]]
     516e)  It is expected that additional base stations kits will be purchased for some (or all) Sol 3 GENI sites in Spiral 5. [[BR]]
     517  Thus, campus site might be able to add additional sectors, at no cost. [[BR]]
     518  Planning for next year will be done later this year. [[BR]]
     519  Consider including additional sectors within your technical plan right away.   [[BR]]
     521f)  Note:  Airspan indicates that they expect to introduce a new base station unit within the next year. [[BR]]
     522  Somewhat reduced performance/range. [[BR]]
     523  Approximately half the cost [[BR]]
     525g)  Airspan indicates that their sector antenna provides:[[BR]]
     526  A 90degree pattern, which is consistent with proper coverage over a 120degree sector.[[BR]]
     527  Four internal elements, to support 2x4 MIMO.[[BR]]
     528  Airspan can provide provide x4 omni-directional antennas, but the cost is much higher, and the range is signifcantly reduced.[[BR]]
     530h)  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]]
     531  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]]
     532  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]]
     533  [  MacroMAXe Configuration Guide][[BR]]
     535i)  Airspan shows that if handover operation is desired, an ASN GW must be provided, plus typically an associated RADIUS (authentication) server.[[BR]]
     536  In this case, the base station unit operates with IP at the interface.  [[BR]]
