Drive Test Results

Drive test tool records following data for both idle mode and dedicated mode MS:

  • Serving cell data

Signal strength, Cell ID, BSIC,  BCCH-  AFRCN, Hopping frequencies, Mobile Allocation
Index Offset (MAIO), Hopping Sequence Number (HSN), Received signal level (RSL) etc.

  • Neighbor cell data

Frequency data, RSL and parameters such as C1, C2 are recorded. C1 and C2 are important
to identify handover errors

  • Call Quality at dedicated mode: a measure of Bit Error Rate (BER) using a 0-7 scale
  • Handover details (neighboring  cell details): RSL, quality level of the  neighboring cells
TEMS tool snapshot is as follows:
