For WTTx, Huawei will commercialize 4x4MIMO and 2CC Carrier Aggregation to offer peak cell rates of over 400Mbps.
Huawei said WTTx offers a larger coverage radius, making the radius of 3.5GHz band comparable to that of 3G at 2.1GHz. WTTx also enables a wide range of services such as video broadcasting, VoIP, and VPN (virtual private network), enhancing an operator’s ARPU.
An end user can purchase a CPE device at an operator’s business center, and access internet by powering-up the device at home. WTTx reduces per-bit data cost, making the wireless broadband business more profitable.
Huawei will provide devices supporting both downlink 4x4MIMO and 2CC carrier aggregation in the second half of 2015 for over 400Mbps. Additional 4.5G technologies, such as downlink 8x8MIMO, 4-carrier aggregation as well as 256QAM will be introduced to WTTx soon. This new technologies are expected to bring 250 percent spectrum efficiency gain, and provide a peak connecting rate of up to 1Gbps.
“WTTx is the complementary solution to provide fiber-like wireless connectivity in the fixed line out-reached areas,” said Veni Xiong, president of Huawei’s Wireless Network TDD Product Line.
