BTS Master™ Base Station Analyzer Features
Overview (continued)
Troubleshooting Fast
An Anritsu exclusive is its Signal Analysis Over-the-Air (OTA)
Pass/Fail Tests. Technicians and RF engineers can quickly
determine the health of a cell site with a one-step Pass/Fail
test. A one-step OTA Pass/Fail test verifies:
• Antenna Feed Line Quality
• Base Station RF Quality
• Base Station Modulation Quality
If a cell site passes, the technician can move on to the next cell
site. If the test fails, the BTS Master equips the technician to
troubleshoot:
• Feed lines and antenna systems
• Base station field replaceable units
• Downlink coverage issues
• Interference problems
• Backhaul bit-error-rates
By quickly determining the health of the cell site with Pass/Fail
testing, the cell site technician becomes more productive and
the BTS Master equips him with the tools to properly diagnose
the root-cause of the problem minimizing costly no trouble
found parts and service calls.
Network Reliability
Studies have shown that network reliability plays a significant
part in subscriber churn. Leading reasons stated for churn are:
• Dropped calls
• Poor coverage
• Network outages
As wireless users come to depend more and more on their
wireless service they expect more and more in network
performance. This makes it more critical than ever to meet
your KPI optimization goals for network availability, network
quality, and network coverage. Ultimately it is about eliminating
reasons for demanding subscribers to churn.
Network Maintenance and Return on Investment
By outfitting cell site technicians with BTS Masters an operator
can attack these reasons for churn. Benchmarking undertaken
by Anritsu has shown that technicians equipped with base
station analyzers provide them with the necessary tools to
troubleshoot degrading KPIs which in turn can reduce churn.
Learn what the return on investment is on equipping more
technicians with the BTS Master Base Station Analyzers from
your local Anritsu sales professional. The BTS Master Base
Station Analyzer can become your vital tool to achieving
optimal network performance.
