About

The Technology For All Wireless project advances technology to address the unique needs of underserved communities and developing regions by developing:

  • New wireless network architectures, systems, and algorithms that enable high-performance ultra-low cost wireless access (link)
  • Health sensing applications that exploit low cost sensing and communication in order to address care of chronic diseases (link)
  • Mobile computing platforms that address the usability needs of underserved communities (link)
  • Real-time environmental sensing using laser spectroscopy (link)

 

“The TFA project is demonstrating innovative diverse spectrum wireless designs, and is showcasing new applications from environmental monitoring to health sensing.” —Edward Knightly

Since 2004, we have operated a research testbed in an under-resourced community in Houston’s East End. The network serves over 4,000 community residents via fully programmable network nodes. Community residents can access the network via legacy 802.11 devices or our custom instrumented mobile phones. Moreover, in April 2011, we deployed the first residential node that can access spectrum spanning from unused UHF bands (callsign WF2XPU) up to traditional Wi-Fi bands. The testbed jointly serves as a community resource and a platform for test-driving the above research advances.
