1. Coverage Analysis
MethodThe method used to collect data for the analysis can be divided into two different measurement types.
Short CallsA short voice call attempt was performed every 50 seconds, including 10 seconds of idle time between two consecutive calls. A script in the TEMS Investigation logging tool automatically initiates the short calls. An event “Call Attempt” was generated every time the script triggered a new call attempt meaning the number was dialled. The other event “Blocked Call” was generated every time the call setup procedure failed. The MS was inside the car and no external antenna was used.
Long CallsLong voice calls are established automatically and are ended by blocks, drops or normal user release. TEMS Investigation tool generated an event “Drop Call” every time the connection dropped. The MS was inside the car and no external antenna was used.
