This makes ZTE the first in the industry to introduce EV-DO Rev.B Phase II technology, who introduced the 9.3Mbps EV-DO Rev.B Phase I system last year.

EV-DO Rev.B technology enhances 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 three-carrier frequency bundling technology, it achieves a peak rate of 14.7 Mbps.

Currently, leading global operators have launched EV-DO Rev.B networks, including China Telecom, WANA, Smart Telecom and PTCL.

To upgrade 9.3 Mbps Phase I networks to 14.7 Mbps networks one requires a baseband channel board replacement and a software upgrade.

Li Jian, GM, CDMA Product Line, ZTE, said: “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.”
