1New or expanded GENI WiMAX base station installations

3Airspan choices:
4
5        2510 Lo:  2496 - 2570 MHz
6
7        2510 Mid:  2560 - 2630 MHz
8
9        2510 Hi:  2620 - 2690 MHz
10
11Each site needs to obtain one or more authorized frequencies in the 2600MHz band:
12                From an existing Educational Broadband Service license owned by their institution
13                By applying to the FCC for an experimental license
14                By negotiatying with Clearwire to "borrow" frequencies
15               
16For 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.
17
18For those sites planning to utilize handover, you should get at least two frequencies.

20Per Gregg Tome on 12/14/11:
21•       Both Ethernet and Fiber connections are available on the Air4GW BS.
22•       The longest Fiber cable we sell is 100M and I would not recommend longer than that.
23From Air4G product specifications:
24
25                 1.3 Fibre Network Interface
26                Standard: IEEE802.3z
27                Interface Speed: 1000Base-SX for short range
28                Communication Mode: Multi Mode
29                Connector LC
30
31                1.4 Ethernet Ports
32                Standard: IEEE802.3
33                Interface Speed: 100Base-Tx
34                Communication Mode: Full Duplex
35                Fibre and Cable: UTP category 5 or 5E
36                Connector: RJ45 Socket
37
38You may choose the fiber Ethernet interface for easier remote connections, and to reduce concerns about lightning surges entering your server room.     
39If so, you will need:   
40                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
41Also, you will need to order:   
42                Up to 100m twin-fiber multi-mode cable (orange), with ODC connectors  (need additional details)
43                Fiber interface with ODC connector for your Ethernet switch  (need additional details)
