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
