This document discusses the key parameters measured during a 3G drive test. It defines parameters for the serving cell including UARFCN, scrambling code, cell identity, name, location, and radio access code. Radio parameters like transmission power, received signal strength, signal to interference ratio, and speech quality are also defined. The document explains that the active set displays the active scrambling codes and the monitoring set shows neighboring cell codes. An example drive test display is promised to demonstrate all the discussed windows and parameters.

2.  On completion of the module one should be clear about the
parameters required during drive test what does it mean and
how much it is important.
 Parameters regarding in windows like :
 a) Service Cell
b) Radio parameters
c) Serving/Active + Neighbors

3. Servicing Cell
 Definitions:
1. Servicing Cell UARFCN : The UTRA Absolute
Radio Frequency Channel Number (UARFCN) is
a unique number given to each radio channel
within the frequency bands used by
the UMTS UTRA.
2. Servicing Cell SC: It displays the name
Servicing Cell Scrambling Code In Idle
Mode/Primary Scrambling Code.
3. Servicing Cell Identity:
4. Servicing Cell Identity (RNC) : It’s displays the
Servicing Cell identity in RNC (Radio Network
Controller)
5. Servicing Cell Identity: (CI)
6. Servicing Cell Name: It’s display The
Servicing Cell Name Ex.: DHUTRA47WA
