ZTE announces another technological breakthrough by achieving the world’s first EV-DO Revision B (Rev.B) VoIP Call on its CDMA2000 system, marking the first time in the industry that a CDMA vendor achieves an impressive 9.3 Mbps download rate and 5.4 Mbps upload rate.
Compared with mature commercial EV-DO Rev.A, what ZTE’s EV-DO Rev.B does is to only upgrade EV-DO Rev.A’s software, with no additional hardware equipment required. Both ZTE’s EV-DO Rev.A and Rev.B adopt identical baseband chipset.
