Feature:     Remote control of electrically tilting antennas

For optimal network coverage and minimal interference with other services and with adjacent cells, it is desirable for a network operator to have control over the tilt of its Node B antennas.  Such control  is currently possible from the O&M network  via implementation-specific protocols between a Node B Element Manager and the Node B itself.  This makes it impossible to have a multi-vendor mix of Nodes B and remote electrical tilting (RET) antennas.

The objective of this feature is:

• to specify a standardized open interface between the Node B and the RET antenna; and

• to specify an appropriate set of signalling commands and control parameters from the Network Manager over the Ift-N interface.

Work to be accomplished by R3 and S5.
