Achieving 1.07 Gbps on a commercial chipset marked a big milestone on the road to 5G
Verizon, Ericsson and Qualcomm Technologies have broken the gigabit speed barrier, hitting download speeds of 1.07 gigabits per second (Gpbs) on commercial silicon and network infrastructure.
The three companies reached the industry milestone using Qualcomm’s Snapdragon X20 LTE modem and 12 simultaneous LTE streams during an Ericsson lab trial.
The additional streams allow for up to 20 per cent 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.
“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,” said Fredrik Jejdling, head of business area networks, Ericsson.
“Achieving 1.07 Gbps with Verizon and Qualcomm Technologies on a commercial chipset is a big milestone on the road to 5G.”
Also of significance, the companies announced, is that the speed was achieved using only three 20MHz carriers of frequency division duplex (FDD) spectrum (using separate transmit and receive frequencies), achieving new levels of spectral efficiency for commercial networks and devices.
These efficiencies will, in theory, enable the delivery of the Gigabit class experience to more customers and lead to new wireless innovations.
In the lab, the 1.07 Gbps speeds were achieved using all licensed band combinations with:
12 LTE streams with three cell carrier aggregation of FDD spectrum;
4x4 multiple in, multiple out (MIMO) per carrier, which uses multiple antennae at the cell tower and on consumers devices to optimise data speeds;
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.
“Qualcomm Technologies has been at the forefront of driving Gigabit LTE in the industry. Our work with Verizon and Ericsson has allowed us to be first in surpassing the Gigabit speed barrier with our Snapdragon X20 LTE modem,” added Mike Finley, senior vice president and president, Qualcomm North America, Qualcomm Technologies.
“This is an important milestone on the path to 5G that will allow for better average speeds for all users and will drive new and exciting consumer experiences.”
