Methodology• To check the presence of Thailand signal in the airport, we use 8 different roaming SIMs and
perform a manual search for GSM signal.Roaming SIM s :
1. O2, UK2. Orange, France
» 3. China mobile» 4. Viettel, Vietnam» 5. T-Mobile, USA» 6. SFR, France» 7. Vodafone, UK» 8. Optus, Australia
• Take the snapshots of the phone screen which shows the existing networks• Measure the receive level of Thai operators at the Wattay airport using TEMS mobiles• TEMS is a measurement tool developed by Ericsson/ASCOM to measure signal strength and other
information used between the mobile phone and the network .

- Thai operators should minimizethe coverage and signal strengthto not cover VTE area
