The Technology For All Wireless project aims to develop fundamental information technology advances that address the unique needs of underserved communities and developing regions. Our research objectives include:
Development of new wireless network architectures and protocols that enable high-performance ultra-low cost wireless access (link)
Development of new health sensing applications that exploit low cost sensing and communication in order to address care of chronic diseases (link)
Development of new mobile computing platforms that address the usability needs of developing region (link)
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 WiFi bands. The testbed jointly serves as a community resource and a platform for test-driving the above research advances.
