As the IP network are getting spread and it is possible to get connected in wider areas, it becomes interesting the SDR opportunity to acquire the specrtum in a place and view and analize it in a place as far as the IP network allows.

Many approaches are possible and the components placed on each side of the network can vary a lot:

• The first approach is to host all component (acquiring, FFT transform, view) on the same host and to get a remote view of the output through well known desktop remotization techniques
  
  • PROS: ease of realization
  • CONS: scalability, portability
• A second approach is to acquire the spectrum and transport the I/Q data to a remote site where the other tasks are exploited
  
  • PROS: likely no limitations to anlisys alghoritm tha can be used
  • CONS: bandwidth requirements, scalability
• A third approach is to acquire and do FFT trasform of the spectrum where it is gathered from the air and to transport just the FFT data. To reduce the bandwidth occupation can be sent just one FFT every N or to seand the mean value of the last N as sending all would be an amount of data too big and maybe unuseful.
  
  • PROS: scalability, portability
  • CONS: time of development

Click&Flickr is a demonstrator application for the programming environment Mobile Processing. It is the result of a learning process which passed through different application versions and experienced remarkable improvements both in the graphical aspects and for what the usability and functionalities concern.

Shelob collects main applications that InLab in cooperation with EmSys designed and developed to handle communications for mesh and vehicular networks. These applications share the same hardware and software platform, based on Alix platform and OpenWRT Linux distribution.
A Shelob description in Italian is available here.

This page describes the HW platform and the OpenWRT configuration, offering a simple tutorial to build the Shelob base system.

Some news from EnviMon project: the hardware platform is ready, the software platform reaches the development final stage.

The main scenario that this project wants achieve is to create a network of wireless, autonomous and low cost devices for environmental data collecting.

The interactive map for HPWNet is online! You can click on the image below to open the dedicate window.

Through the interactive map it is possible to view in real time the state of each device that is installed in HPWNet and analyze link throughput.
 

A deeper analysis upon the programming environment Mobile Processing showed a wider view of the aspects, advantages, disadvantages and bugs of the open project initiated by Francis Li.

Francis Li [http://www.francisli.com/] is an interaction designer and software engineer who developed this branch of the open source Processing project (which is instead originally designed for desktop and Internet applications by means of a set of libraries for Java programming).

The so called digital divide affects some geographical areas, such as mountain and valley. The term digital divide refers to the gap between those people with effective access to digital and information technology and those without access to it. The unequal access by some members derives from socioeconomic (rich/poor), racial (majority/minority), generational (young/old) or geographical (urban/rural) factors.
