China Telecom launches pre-commercial EV-DO Rev.B network

Huawei has announced that it has deployed two CDMA2000 1x EV-DO Rev.B networks in Beijing and Guangzhou for China Telecom. The Rev.B solution will enable the telco to improve capacity, throughput and latency on its existing EV-DO network and offer sophisticated 3G services to its subscribers including VoIP, voice-on-demand and media streaming. The EV-DO Rev.B networks support downlink data rates of up to 9.3Mbps. Based on 2.1GHz and 800MHz dual-band, the new networks will be able to enhance the carrying capacity to deal with the explosion of data services and provide stable and reliable high-speed mobile broadband experiences for 3G users.
