Disadvantage of Independent Antenna U900&G900 Additional equipment cost •New antenna •New pole •New feeder •New TMA Limitation of evolution • lack of installation space for LTE/SAE evolution Sites renegotiation •New antenna and pole Additional Cost Slow the pace of site deployment • Longer time to market Additional installation cost •New antenna •New pole •New feeder Additional maintenance cost •New antenna HUAWEI TECHNOLOGIES CO. LTD.. Huawei Confidential Page 53 . Antenna Solution Summary Solution Independent antenna Advantages Easy to implement RF optimization respectively. Co-antenna with SASU Save the installation space and cost for antenna and feeder 1) 3G and 2G system can not adjust the down tilt angle and azimuth independently; 2) downlink increase less than 0.6dB loss. Co-antenna with 3dB combiner Save the installation space and cost for antenna and feeder 1) 3G and 2G system can not adjust the down tilt angle and azimuth independently; 2) downlink increase more than 3 dB loss. Co-antenna with GU mRRU/mRFU 1) save the space and cost of antennas and 3G and 2G system can not adjust the down tilt angle and azimuth feeders; 2) No insertion loss; 3) Easy RF tuning for 2G/3G co-coverage objectives; independently; Disadvantages much additional cost needed HUAWEI TECHNOLOGIES CO., LTD.
