  1. 1. Proprietary and Confidential UMTS Antenna ConfigurationUMTS Antenna Configuration ScenarioScenario
  2. 2. Proprietary and Confidential Slide 2 Scenario 1: GSM UntouchedScenario 1: GSM Untouched Existing Configuration: – 3 dual pol antennas (72 inches); antenna count can be increased – 2 lines per antenna; additional lines can be installed – 2 TMAs – No RET Proposed Configuration: – Add one new AWS antenna (dual pol) with RET for UMTS (4th antenna) – Add two new feeder cables for UMTS and RET cable – Add new AWS twin TMA
  3. 3. Proprietary and Confidential Slide 3 Scenario 1: GSM Untouched (continued)Scenario 1: GSM Untouched (continued) Pros: – No impact on GSM as the system will be untouched (except for some possible minor movement of one antenna depending on existing arrangement) – Easier implementation – Azimuth and tilt can be independently adjusted for both GSM and UMTS Cons: – Additional rent cost for the extra TMA and antenna for UMTS – Additional active elements means more points of failure

  6. 6. Proprietary and Confidential Slide 6 Scenario 2: RET For AllScenario 2: RET For All Existing Configuration: – 3 dual pol antennas (72 inches); antenna count can be increased – 2 lines per antenna; additional lines can be installed – 2 TMAs – No RET Proposed Configuration (1): – Add one new AWS antenna (dual pol) with RET for UMTS (4th antenna) – Replaced old PCS antennas with new antennas with RET capability – Add two new feeder cables for UMTS and RET cables – Replace existing TMAs with twin AWS/PCS TMAs
  7. 7. Proprietary and Confidential Slide 7 Scenario 2: RET For All (continued)Scenario 2: RET For All (continued) Pros: – GSM gets newer antennas and RET capability – GSM gets new TMAs – Azimuth and tilt can be independently adjusted for both GSM and UMTS Cons: – Cost for replacing GSM antennas and TMAs – Additional rent cost for the extra TMA and antenna for UMTS

Proprietary and Confidential Slide 10 Scenario 3: I Love QuadsScenario 3: I Love Quads Existing Configuration: – 3 dual pol antennas (72 inches); antenna count cannot be increased – 2 lines per antenna; additional lines can be installed – 2 TMAs – No RET Proposed Configuration: – Replace all antennas with quad pol AWS with RET capability – Replace existing TMAs with new AWS/PCS twin TMAs – Add two new feeder cables for UMTS and RET cables
  11. 11. Proprietary and Confidential Slide 11 Scenario 3: I Love Quads (continued)Scenario 3: I Love Quads (continued) Pros: – Same antenna count (a plus for zoning, leasing and structural aspects) – RET is separate between GSM and UMTS sharing the same quad pol antenna (independent tilt adjusted for GSM and UMTS) Cons: – Azimuth cannot be independently adjusted for the antenna where GSM and UMTS is located

  14. 14. Proprietary and Confidential Slide 14 Scenario 4: No Room To GrowScenario 4: No Room To Grow Existing Configuration: – 2 quad pol antennas (72 inches); antenna count cannot be increased – 4 lines per antenna (no additional lines can be added) – 2 TMAs – No RET Proposed Configuration: – Replace all existing antennas with quad pol AWS with RET capability – Replace existing TMAs with new AWS/PCS twin TMAs – Combine GSM TRXs to free up 2 feeder cables for UMTS (ensure even combining of GSM TRXs) Note: This scenario is applicable also for existing configuration using dual pol antennas and no new lines can be added
  15. 15. Proprietary and Confidential Slide 15 Scenario 4: No Room To GrowScenario 4: No Room To Grow (continued)(continued) Pros: – UMTS can be deployed on the site – New antennas for GSM – New TMAs for GSM – Independent tilt and azimuth adjustment for both GSM and UMTS Cons: – Additional loss in GSM (due to combining) – Increased cost to offset additional loss due to combining if MCPAs are used – Loss of space diversity in GSM

  19. 19. Proprietary and Confidential Slide 19 Scenario 5: “Two” Few Lines (continued)Scenario 5: “Two” Few Lines (continued) Pros: – UMTS can be deployed on the site – New antenna for GSM – New TMA for GSM – Diplexing option is cheaper than MCPA Cons: – Additional loss in GSM and UMTS (due to diplexing but lower than combining) – Possible intermodulation product at certain frequency pairs – Azimuth and tilt cannot be independently adjusted for both GSM and UMTS
