    3737=== GENI WiMAX site frequencies, for Airspan order  ===
    3838
    39 New or expanded GENI WiMAX base station installations
    40 
    41 Airspan choices:
    42 
    43         2510 Lo:  2496 - 2570 MHz
    44 
    45         2510 Mid:  2560 - 2630 MHz
    46 
    47         2510 Hi:  2620 - 2690 MHz
    48 
    49 Each site needs to obtain one or more authorized frequencies in the 2600MHz band:
    50                 From an existing Educational Broadband Service license owned by their institution
    51                 By applying to the FCC for an experimental license
    52                 By negotiatying with Clearwire to "borrow" frequencies
    53                
    54 For those sites that expect to operate two or three sectors from one site, you should get two or three frequencies, so that a Mobile Station on the edge between two sectors is able to see and pick one sector or the other.
    55 
    56 For those sites planning to utilize handover, you should get at least two frequencies.
    57 
    58 Per Gregg Tome on 12/14/11:
    59 •       Both Ethernet and Fiber connections are available on the Air4GW BS.
    60 •       The longest Fiber cable we sell is 100M and I would not recommend longer than that.
    61 From Air4G product specifications:
    62 
    63                  1.3 Fibre Network Interface
    64                 Standard: IEEE802.3z
    65                 Interface Speed: 1000Base-SX for short range
    66                 Communication Mode: Multi Mode
    67                 Connector LC
    68 
    69                 1.4 Ethernet Ports
    70                 Standard: IEEE802.3
    71                 Interface Speed: 100Base-Tx
    72                 Communication Mode: Full Duplex
    73                 Fibre and Cable: UTP category 5 or 5E
    74                 Connector: RJ45 Socket
    75 
    76 You may choose the fiber Ethernet interface for easier remote connections, and to reduce concerns about lightning surges entering your server room.     
    77 If so, you will need:   
    78                 Two short 2m fiber pigtails, to connect from the LC connectors on the base station to a more-standard ODC connector;  these will be included in each base station order to Airspan
    79 Also, you will need to order:   
    80                 Up to 100m twin-fiber multi-mode cable (orange), with ODC connectors  (need additional details)
    81                 Fiber interface with ODC connector for your Ethernet switch  (need additional details)
