Verizon, the largest mobile operator in the US, in partnership with Ericsson and Qualcomm, has surpassed the Gigabit speed barrier in a LTE-Advanced Pro trial.
The operator showcased 1.07Gbps download speeds using the Qualcomm SnapdragonTMX20 LTE Modem (the first announced modem to support Category 18 LTE speeds) and Ericsson’s Radio System and LTE software, 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 20MHz carriers of FDD (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, said Verizon.
The companies achieved the 1.07 Gbps industry milestone by combining 12 LTE streams with 3 cell carrier aggregation of FDD spectrum, 4x4 MIMO per carrier (multiple in, multiple out) and 256 QAM per carrier.
