University Grading Dual-Mode Phones

摘要

George Washington University is testing 25 dual-mode wireless phones that allow users to move between indoor Wi-Fi networks and outdoor cellular networks.rnIf the technology proves reliable and its promise to cut costs bears out, the university could support up to 30,000 dual-mode phones for students and staffers on its three campuses by 2009, said Bret Jones, director of technology and engineering at the school.
