ZTE Corp today claimed successful completion of EV-DO Rev.B Phase II data call trials achieving a download speed of 14.7 Mbps thereby exceeding its own 9.3 mbps speed recorded last year.

“Over the past ten years, ZTE has invested enormously in R&D to advance and innovate CDMA technologies that meet CDMA operators’ demand for competitive leadership,” says Ms. Li Jian, General Manager of ZTE’s CDMA Product Line. “The system we made for the data call adopts ZTE’s industry-leading SDR platform-based Uni-RAN solution to meet common mode evolution needs of EV-DO Rev.B and LTE.”

EV-DO Rev.B technology is known to enhance spectrum efficiency to extend mobile talk-time by approximately 30 percent and effectively prolong standby time. A new baseband chip is also adopted in the Rev.B Phase II system. By introducing 64QAM high-order modulation technology, it supports a single carrier frequency with a downlink speed of 4.9 Mbps and with 3-carrier frequency bundling technology, it achieves a peak rate of 14.7 Mbps.
