- Configuration of Postal Operators
- Analyze the real radiofrequencies exposure in a realistic environment
- Perform E-field measurements transmitted by different sources (FM, TV, GSM, DCS, UMTS, HSDPA, Wi-Fi ...) over a day (in different sites)
- Study the distribution & temporal variation of the E-field received from these different sources
- Analyze and quantify the real traffic (TRX/CPICH) received from these networks (using algorithms & statistical analysis)
- Define extrapolation factors to evaluate the maximum real exposure transmitted by the 2G and 3G base stations over a day from an instantaneous measurement (30min) performed at any time during the day
- Analyze the multi exposure in Downlink generated by these sources
- Use the EMF Visual software to simulate 3D exposure to electromagnetic fields in an environment which can be created
- Simulate exposure to cities & districts with an internal software (in Orange Labs)
- Analyze the multi exposure in Uplink from a mobile phone (different sources emit at the same time e.g. GSM & W-IFI)
- Evaluate the SAR (Specific Absorption Rate) near a multi sources with FDTD simulations (GSM, DCS, UMTS, LTE & Wi-Fi)
- Study the compliance of the mobile phones while using two services simultaneously
- Analyze the exposure to MIMO sources emitted from a mobile phone
- Proposal of a new parameter to assess in real utilization the exposure to cell phones & to compare the performance of different mobile phones
- 6 Publications and two papers in a journal
- Participation in different international conferences
- Study the state of operation of the mobiles GSM, GPRS, UMTS (protocol, air interface, architecture…)
