1. Measurement methodology:
Measurement devices: Nemo5.0 (software and hardware), Laptop, GPS …
Measurements are performed in cyclic mode, in which multiple calls are made
automatically during entire drive test routes.
The calls are defined with auto-sequence:
- Call duration: 120 seconds

- Idle time: 10 seconds
Using four test mobiles equipment:
- MS1 (Call Origination) and MS2 (Call Termination) used for Vinaphone network.
- MS3 (Call Origination) and MS4 (Call Termination) used for Viettel network.
Mobiles equipment work in Dedicated Mode which are set to be synchronized to make
the dial-up at the same time.
