A handheld wireless device in development by two University of Arizona engineering professors could answer the question of how we create more wireless connections when so few remain in the spectrum.
Envision a world without lost signals or time-consuming searches for Wi-Fi connections. UA electrical and computer engineering professors Marwan Krunz (right, top) and Hao Xin (right, bottom) are working to shift how we structure wireless systems and eliminate wireless scarcity.
The surge in Wi-Fi enabled devices has been a boon for society but a strain on the wireless spectrum that provides the frequencies they use. Many of the frequencies are fixed, having been allocated exclusively for radio, television, military, mobile and other operators. What remains is limited.
