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. |

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) |
