New 4G LTE-A Service in Guangzhou offers downlink rates of more than 300Mbps for users with new CAT 9 handsets, tripling the speeds of existing TD-LTE networks
17th June 2015, Shenzhen, China – ZTE Corporation (0763.HK / 000063.SZ), a major international provider of telecommunications, enterprise and consumer technology solutions for the Mobile Internet, is pleased to support China Mobile in the deployment of 3-Carrier Aggregation 4G LTE-A (LTE-Advanced) service based on CAT 9 devices.
With the new China Mobile 3-CA service in Guangzhou, users with CAT 9 devices powered by Qualcomm® Snapdragon™ 810 processor with X10 LTE may enjoy downlink data rates of over 300Mbps, more than triple the speeds of existing TD-LTE networks. As the provider of radio access and core networks, ZTE supported the upgrade of China Mobile’s network without a major overhaul of infrastructure and software, testament to ZTE’s flexible and efficient software defined radio (SDR) platform.
LTE-A, defined within 3GPP R10 and following releases, will help 4G LTE networks evolve and attain 1 Gbps data rates on downlink and 500 Mbps for uplink. As one of the key techniques within LTE-A, carrier aggregation multiplies network transmission speed, by combining 2 or 3 continuous or non-continuous carrier bands at present. Eventually, a higher number of carrier bands may be combined.
Since the deployment of carrier aggregation involves the upgrading of every single aspect of the whole network, from chipset, terminal to system, commercialization is a prolonged process of evolution. The commercial deployment of 3-carrier aggregation is a breakthrough for LTE-A development, giving operators increased network capabilities to provide superior user experience to subscribers.
ZTE is committed to LTE-A commercialization and ecosystem development. At this year’s Mobile World Congress in Barcelona, ZTE partnered with China Mobile and Qualcomm Technologies to successfully demonstrate TD-LTE DL 3CA service with commercial terminals for the first time. The commercial 3CA LTE-A network launch in Guangzhou was the culmination of seamless cooperation between the three companies. ZTE will further enhance its cooperation with partners in LTE-A commercialization to improve the mobile broadband experience for end-users.
