ActivitiesThe Wireless System Lab (WisyLab) is dedicated to research, link-level simulation, design and implementation of physical layer (PHY) components of wireless communication systems, using software defined radio (SDR) techniques. Activities concern both cellular systems (GSM, UMTS, WiMax,
LTE) and short-range networks (WiFi, ZigBee, UWB).
Design and development are carried out using Matlab, Simulink, C/C++, LabView and tools for DSP and FPGA prototyping. A 2x2 MIMO test-bed (scalable up to 4x4 nodes) with RF up/down converters and generators/analyzers has been developed in cooperation with the National Research Council (CNR).
In recent years activities have been focused on the design of cooperative techniques for communication and processing in peer-to-peer wireless networks, with emphasis on distributed algorithms. In particular, system prototypes based on IEEE 802.15.4 wireless sensor networks at 2.4GHz have been designed for monitoring and control of industrial infrastructures (railways, oil and gas refinery plants), home automation (smart surveillance), active/passive localization of mobile users in indoor environments, traffic monitoring for intelligent transportation systems, seismic exploration by wireless networks of geophones.
