    China Mobile deploys wideband Massive MIMO

    China Mobile Shanghai and Huawei have jointly deployed the world’s first wideband Massive MIMO site to help improve 4G network spectral efficiency.

    China Mobile has been focusing on the design of wideband Massive MIMO as part of its research on 5G. The technology been oriented specifically towards large-scale commercial use by the operator.

    Wideband Massive MIMO allows a single module to support the activation of three 2.6-GHz carriers, potentially allowing for a three-fold increase in the spectral efficiency of cells.

    The live deployment in Shanghai has achieved peak cell throughput rates of 72Mpbs using an uplink 8-stream capability configuration, as well as 630Mbps downlink.

    Huawei said the technology supports a smooth transition to CloudRAN architecture, while its in-house developed chips and optimization techniques helps provide processing capabilities four times higher than that of the industry standard.

    The technology is particularly suited to meeting specialized coverage requirements such as high-rise buildings.

  • Telstra close to launching Gigabit-class LTE

    Telstra close to launching Gigabit-class LTE

    Telstra has worked with Qualcomm, Ericsson and NETGEAR to develop the world’s first Gigabit-class LTE mobile device and Gigabit-class commercially ready LTE network.

    A new NETGEAR mobile router based on Qualcomm’s Snapdragon X16 LTE modem and Wi-Fi equipment will enable download speeds of up to 1Gbps over Telstra’s upgraded LTE network, which uses equipment supplied by Ericsson.

    Telstra now plans to conduct device, network and user testing ahead of a commercial launch, which is expected within the next few months.

    Combined, the equipment is capable of delivering Gigabit-level LTE speeds through a combination of 3x carrier aggregation, 4×4 MIMO on two aggregated carriers and 2×2 MIMO on the third, as well as 256-QAM.

    “We pride ourselves on our connectivity expertise and we continue that tradition today by completing the first commercialization of a Gigabit Class LTE network and device,” Telstra group managing director of networks Mike Wright said.

    “With the world’s first Gigabit Class LTE network, we have substantially improved our network capacity and increased real-world LTE download speeds, while also gaining a distinct advantage over competitors as we can now offer an entirely new class of LTE service.”

    Ericsson head of RAN products Per Narvinger added that “Telstra’s commercial ready Gigabit Class LTE network and device is an important milestone as it paves the path to 5G.”
