NEW YORK – Verizon, Ericsson and Qualcomm Technologies have surpassed the Gigabit speed barrier on 4G LTE in a lab trial.
The companies said Monday that they achieved 1.07Gbps download speeds with commercial silicon and network infrastructure using the Qualcomm SnapdragonTMX20 LTE Modem, the first announced modem to support Category 18 LTE speeds.
According to the press release, the industry milestone was achieved by using 12 simultaneous LTE streams, which allow for up to 20% increase in peak data rates and capacity with a corresponding improvement in average speeds. Ericsson’s Radio System and LTE software, in concert with a mobile test device based on the Snapdragon X20 LTE modem, enabled these high speeds.
The release also said that, in the lab test, the 1.07 Gbps speeds were achieved using all licensed band combinations with:
– 12 LTE streams with 3 cell carrier aggregation of FDD spectrum;
– 4×4 MIMO per carrier (multiple in, multiple out), which uses multiple antennae at the cell tower and on consumers devices to optimize data speeds; and
– 256 QAM per carrier, which enables customer devices and the network to exchange information in large amounts, delivering more bits of data in each transmission, significantly enhancing data speeds.
“Ericsson is working across the industry to improve the end-user experience and to develop new functionalities and advancements with greater spectral efficiency on LTE. Achieving 1.07 Gbps with Verizon and Qualcomm Technologies on a commercial chipset is a big milestone on the road to 5G”, said Ericsson’s head of business area networks Fredrik Jejdling, in the release.
