Verizon, Ericsson and Qualcomm Technologies continue to push the LTE speed envelope breaking the Gigabit speed barrier. The companies achieved an industry first with commercial silicon and network infrastructure with 1.07 Gbps download speeds using the Qualcomm Snapdragon X20 LTE Modem during an Ericsson lab trial.
This 1.07 Gbps achievement builds on Verizon’s recent announcement about Gigabit LTE with support for License Assisted Access (LAA). Also of significance, the 1.07 Gbps speed was achieved using only three 20 megahertz carriers of (Frequency Division Duplex using separate transmit and receive frequencies) spectrum, achieving new levels of spectral efficiency for commercial networks and devices. These efficiencies will enable the delivery of the Gigabit class experience to more customers and lead to new wireless innovations.
The companies achieved the 1.07 Gbps industry milestone by using 12 simultaneous LTE streams, which allow for up to 20 percent 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 lab tests also used 4×4 MIMO per carrier, 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.
