ZK Celltest has added PN Scanning as an optional feature on its DXM line of test equipment. PN scanning detects and logs all desirable and undesirable (interfering) PN signals impacting working subscriber phones in a CDMA network. Undesirable PN signals at levels close to the Active Sets result in Pilot Pollution that is interference, which causes poor audio quality and high FER. This in turn reduces base station capacity because the excess noise and the increased power levels required on working phones result in fewer additional calls being processed.
