| Drones |
Following the current trends in wireless systems technology, the lab recently acquired a quad-copter (IRIS+ by 3DR) for drone applications. Currently, IRIS+ is being used both for research and educational activities.
Projects:
- Analysis of LTE network
- Sensor Applications
- An Arduino-Based Subsystem for Controlling UAVs Through GSM
| E/M radiation measurements |
Since 2008 the lab is equipped with the SRM 3000 selective radiation meter of Narda Safety Solutions and is able to perform measurements for: SafetySafety evaluation, Spectrum analysis, Time analysis
Example of field measurement
