| 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
Measurement location in the center of Tripolis
Field strength (V/m) for different frequency bands (Project: ‘EU/GR-INTENTION’ 2013)
Projects:
- Field measurements in urban and suburban environments,
BSc Thesis completed in 2014. The level of the electromagnetic radiation was studied in urban, suburban and rural
environments in the area of Tripolis. The results were compared to the exposure limits set by the Greek legislation and to those proposed by the Bio-Initiative report.
| Narrowband Propagation Measurements |
Narrowband propagation measurements for outdoor and indoor environments.
Power model for the corridor (Tsesis: Mpasiaka-Tsirivakou 2012)
Projects:
- Indoor Power Measurements
BSc Thesis completed in 2012. In this thesis extensive indoor power measurements were held in the first floor of the Department’s building in order to determine an indoor path loss prediction model for this area.
- Study of antennas radiation pattern in realistic environment
- Electromagnetic radiation measurements for GSM-900 networks
Outside the department building (Thesis: Simatis 2006)
GSM received signal, duration 4 hours. (Thesis: Simatis 2006)
