| 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)
