Huawei Confidential RCU RET- Remote Electric Tilt RET: mandatory for new antennas and all bands in case of dual band antennas. In case of antennas 900 with GSM 900 configuration, RET activation should be quoted to Phase 1. Antennas 900 configured just for UMTS 900, RET activation should be quoted in Phase 3. One step quotation does not distinguish between phases, so RET is quoted in the year that the antenna is installed. For new antennas RET must also be activated in the network. Introduction and activation of RET in reused antennas should be preciated as an optional issue, to be quoted in an alternative TCO. HUAWEI TECHNOLOGIES CO., LTD.
