ClearGain® Ground-Mounted Amplifiers
As mobile usage continues to increase, service providers are faced with the challenge of optimizing
and expanding their wireless networks to provide new and existing services. ADC’s ClearGain®
Ground-Mounted Amplifiers (GMAs) minimize the cost of network expansion and improve quality
of service, allowing service providers to increase profitability from new and existing services.
ClearGain GMAs improve signal quality by boosting the uplink signal of a mobile system to
increase receiver performance and improve overall coverage.

Introduction
Unacceptable network quality is one of the main reasons for mobile subscriber churn. With increasing
industry churn rates, a service provider’s entire customer base could be lost in as few as three years. The
cost of acquiring new subscribers to replace the existing customer base can be enormous. Improvements
in quality of service can directly impact a service provider’s profitability through the cost savings
associated with increased subscriber retention and the additional revenue gained from increased billable
minutes of use resulting from improved signal quality.
Whilesubscribersarewillingtopayapremiumfordataservices,improvedQoSisnecessarytoprovide
new data services. Due to the tradeoff between bit rate and bandwidth inherent to data services,
improved signal quality is required to achieve the same level of performance at even higher data rates.
ADC’s ClearGain GMAs help provide this improvement in signal quality.
ClearGainGMAsimprovesignalqualitybyboostingtheuplink(RX)signalofamobilesystem.GMAs
perform this amplification with the lowest possible noise contribution, resulting in a substantial increase
inreceiverperformanceandanimprovementinoverallcoverage.TheseimprovementsinQoSallow
mobile subscribers to place more calls, make longer calls, and successfully complete calls in an expanded
geographic area, resulting in increased revenue.
SystemOverview
The ClearGain GMA system is modular, consisting of an amplification module and a power distribution
unit(PDU),providingfullcompatibilitywithallbasestations.
The ClearGain GMA offers dual duplex operation and incorporates a highly advanced fixed-gain, low-
noiseamplifier(LNA)andhigh-performancefiltersforaddedreliability.
