  48. 6113 CITA

  49. 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
