3 | Airspan choices:
|
---|
4 |
|
---|
5 | 2510 Lo: 2496 - 2570 MHz
|
---|
6 |
|
---|
7 | 2510 Mid: 2560 - 2630 MHz
|
---|
8 |
|
---|
9 | 2510 Hi: 2620 - 2690 MHz
|
---|
10 |
|
---|
11 | Each 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 |
|
---|
16 | 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.
|
---|
17 |
|
---|
18 | For those sites planning to utilize handover, you should get at least two frequencies.

20 | Per 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.
|
---|
23 | From 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 |
|
---|
38 | You may choose the fiber Ethernet interface for easier remote connections, and to reduce concerns about lightning surges entering your server room.
|
---|
39 | If 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
|
---|
41 | Also, 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)
|
