HPWNet – High Performance Wireless Network

HPWNet is an experimental wireless network developed by CSP since 2005. The project started with two aims: to develop a wireless backbone in the urban area of Turin, which can be used for the rapid activation of wireless nodes in the city and as a point of departure for extensions towards neighboring municipalities.

Today, HPWNet […]

A real-time video broadcasting system based on the GNU Radio-USRP2 platform

A video broadcasting system conforming to the DVB-T digital TV broadcasting standard has been developed using the GNU Radio framework. The system achieves real-time operation and supports most of the communication modes defined in the standard. Using a USRP2 board with a suitable radio front-end, interoperability with commercial receivers has been proved.

The paper has […]

Identification of packet exchange patterns based on energy detection: the Bluetooth case

A time-domain recognition of different wireless technologies may be obtained using energy detection. In this work, an energy detector was implemented using the Universal Software Radio Peripheral SDR platform. The energy detector output allows the formation of a packet presence/absence diagram. Experimental results indicate that the observation of Bluetooth packet exchange patterns reveals technology-specific MAC […]

There is now overwhelming evidence that the current organisation of our economies and societies is seriously damaging biological ecosystems and human living conditions in the very short term, with potentially catastrophic effects in the long term. The enforcement of novel policies may be triggered by a grassroot approach, with a key contribution from […]
