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

Overcome EDGE Coverage Reduction

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”

Tower Mounted Amplifiers (TMA) Overview

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.


© CommScope

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
