Market Trends and Drivers
3G Service
� UMTS overlay could require additional lines or antenna feed consolidation
� Use of in-band WCDMA (850/1900) would necessitate the addition or reuse of antenna feedlines
GSM Traffic Growth
� Increased TRX counts with fixed number of antenna lines require transmit path consolidation
� Cell splits no longer looked upon favorably –too costly
Reduced OPEX and CAPEX expenditures determining factors in purchase decisions
Maintain system performance while adding capacity and/or reduce holes in coverage

Capacity
• Capacity – finite number of calls that can be handled on a site.
• Once capacity limit is reached site begins “blocking” calls.
- Reduced revenue.
• As traffic on a site increases, capacity must grow- First plan of attack to add capacity is adding antennas
• Requires additional feeders
• Impact to tower loading and lease costs
- Transmitter combining solutions
• Combining solutions typically use lossy hybrid combiners
• 3-4 dB loss for every “combination”

Improve Coverage and Quality
Uplink
Downlink
Before TMA – Uplink Limited System
Uplink
Downlink
• In an UL limited system, the DL can support wider coverage than the UL. Since, it is a two-way system, the coverage is limited by the UL.• By adding TMA on a UL limited system, the link can be balanced and the sector can have a bigger coverage.

Reduce Mobile Power - Increases Mobile Battery Time
• Required Mobile TX Power will be reduced for the same path loss for sectors with TMA.
• Increase in Mobile Battery time

TMA Benefits - Summary
• Improve Uplink performance- Provide UL gain
- Improve the Noise figure
- Reduce MS UL power
- Reduce interference
• Increase in Capacity and Coverage for UL limited system- Depending on the cell design, it could reduce number of cell site
deployment and capacity hardware for the BTS/Node B.
• Provides additional RX filtering
