6113 CITA



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



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



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
