Verizon, Ericsson, and Qualcomm Demonstrate 953 Mbps Wireless Speeds in Real-World Conditions

In a U.S. wireless industry first, Verizon, Ericsson, and Qualcomm Technologies, have announced that they reached an astounding 953 Mbps datarate (just under 1 gigabyte per second) in a joint commercial network deployment in Boca Raton, Florida. While lab tests have shown comparable speeds in recent months, this is the fastest announced speed achieved in a real-world, dynamic network environment leveraging Licensed Assisted Access (LAA) technology.

The demonstration used all commercially available Verizon network components including a cell site, hardware, software, and backhaul. Riding on the backbone of Verizon's most reliable network infrastructure, Ericsson provided the most advanced remote radio head in the industry. The micro Radio 2205 for LAA, designed for unlicensed spectrum use, provides small dimensions, flexible mounting and superior performance, and is a component of the Ericsson Radio System, an end-to-end modular radio network portfolio of hardware and software designed to fit all site types and traffic scenarios as networks grow in scale and complexity on the road to 5G. Qualcomm Technologies provided a Qualcomm Snapdragon 835 mobile platform test device, with Gigabit LTE capability thanks to the integrated Snapdragon X16 LTE modem.

A combination of the latest 4G LTE wireless technologies is required to reach these industry-leading speeds. Carrier aggregation, a key technological advancement, bands multiple spectrum channels together to allow data to flow more efficiently resulting in dramatically faster peak speeds. Verizon led the industry last summer when it launched LTE Advanced with two channel carrier aggregation nationally and has completed deployment of three channel carrier aggregation using its licensed spectrum.

To reach gigabit class speeds, Verizon used a combination of licensed and unlicensed spectrum for the first time. This four carrier aggregation uses LAA (License Assisted Access) to combine Verizon's spectrum holdings with unlicensed spectrum, which takes advantage of spectrum where home and commercial Wi-Fi technologies exist. In addition to four channel carrier aggregation, other technological advancements include:

  • 4x4 MIMO (multiple in, multiple out) which uses multiple antennae at the cell tower and on consumers' devices to optimize data speeds
  • 256 QAM 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
