Building Devices for Anytime-Anywhere Wireless Connectivity

Envision a world without lost signals or time-consuming searches for Wi-Fi connections. UA electrical and computer engineering professors Marwan Krunz and Hao Xin 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.

Krunz's solution to frequency scarcity lies in dynamic spectrum access, or DSA.
