Have Yingbo Hua (left) and Ping Liang solved the "spectrum crunch?"
Wireless carriers love to talk about a Spectrum Crunch. Like oil, wireless spectrum is a finite resource. Companies like AT&T warn that smartphone proliferation is eventually going to leave those "wells" dry. Carriers' answers to the problem usually involve government (less regulations, and more federally-owned spectrum released). However, researchers at U.C. Riverside have another solution: make those networks more efficient.
