What is CiTA?

• Cell Integrity Test
• Tests the whole cell antennas as well as BTS RF
  performance
• Used to assess the quality of the radio channel
  between a BTS and a mobile anywhere in the cell

50
Benefits of CiTA

• Checks Uplink Downlink quality
• Checks the citing orientation of all antennas
• Checks the performance of masthead LNAs
• Checks UL/DL antenna balance of site
• Checks voice quality BER
• Checks cell coverage
• Identifies interference
• Identifies potential site location
• Optimises network performance

51
CiTA Process

• Racal 6113 provides a one cell network
• Make calls using mobile/test sim
• Loopback in 6113 for voice quality assessment
• Loopback in 6113 for BER test measurements
• Monitors RxLevel/RxQuality Reports

Live Testing Benefits

• BTS in Real Traffic on real network conditions.
• Dont Need take site off air and so can perform
  routine maintenance.
• Scan Mode to find Network BCCH(s)
• Transmitter Tests (freq error, Phase Error, Mod
  Spectrum, BER)
• Call Set-up for Receiver Sensitivity and Rx BER
  Tests

60
Live Tests Process

• Connect to BTS Rx monitor port(s)
• Connect to tee in up-link A-bis (high
  impedance)
• Perform Call Set-up with Live SIM
• Receiver Bit Error Ratio via A-bis
• Note limited control with Call Setup
