NEW YORK � Verizon, Ericsson and Qualcomm Technologies recently achieved 1.07 Gbps download speeds using the Qualcomm SnapdragonTM X20 LTE Modem, the first announced modem to support Category 18 LTE speeds, during an Ericsson lab trial.
The 1.07 Gbps speed was achieved using only three 20 MHz carriers of FDD (Frequency Division Duplex using separate transmit and receive frequencies) spectrum, achieving new levels of spectral efficiency for commercial networks and devices, and these efficiencies will �enable the delivery of the Gigabit class experience to more customers and lead to new wireless innovations� according to Verizon.
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
- 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
- 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.
