Case #2: WiMAX 4 Subcells+TD-LTE 1 Carrier/3 Sector, 2Tx/2Rx
Follow the steps below to connect CPRI cables for WiMAX 4 subcells + TD-LTE
1 Carrier/3 Sector 2Tx/2Rx configuration of U-RAS Flexible V2.
When U-RAS Flexible V2 supports WiMAX/TD-LTE multi-mode, up to 4 WiMAX
channel cards (MRA-F) can be mounted on the U-RAS Flexible V2 to support 4 subcells.
The operator can set operating sectors and frequencies for each subcell.
The following example shows the pin map where an alpha sector has 3 and a beta sector
has 1 respectively among 6 WiMAX subcells.
