Verizon, Nokia and Qualcomm Technologies recently reached peak data speeds of 1.45 Gbps on LTE in a live commercial environment using six channel carrier aggregation, a key LTE Advanced technology.
Carrier aggregation combines multiple channels of spectrum to provide greater efficiency for data sessions transmitting over wireless networks. By using a combination of both licensed and shared spectrum, for the first time in the U.S. in a commercial environment the three companies combined six separate channels of spectrum.
The record-breaking speeds on 4G LTE were reached on Verizon’s network in New York using a combination of Verizon’s licensed PCS and AWS spectrum in conjunction with four carriers of LAA (License Assisted Access) spectrum. The demonstration used Nokia’s AirScale base station and Qualcomm Technologies’ mobile test device powered by the Qualcomm Snapdragon TM X24 LTE modem.
The demonstration in New York also used LTE Advanced feature, 256 QAM (enabling the network to deliver more bits of data in each transmission) and 4x4 MIMO (using multiple antennas at the cell tower and in the device to minimize errors and optimize data speeds.) In mid-2018, Verizon announced these technologies were available in over 1,100 markets nationwide.
