BOCA RATON, Fla. - The reality of true wireless gigabit speeds is within reach. In a U.S. wireless industry first, Verizon, Ericsson, and Qualcomm Technologies, Inc., a subsidiary of Qualcomm Incorporated, announced today they reached an astounding 953 Mbps (just under 1 gigabit 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.
Verizon was the first national wireless provider to introduce 4G LTE speeds in 2010, spurring an ecosystem of video viewing and data sharing at a pace not realized before. Since that time, Verizon and its partners have continued to evolve the 4G LTE network, enabling it to carry more robust applications and solutions for consumers, enterprise customers and government agencies.
"Today's milestone is a great example of our approach to new technology - we deploy the latest capabilities reliably and in real-world environments, not just in a lab," said Nicola Palmer, Chief Wireless Network Officer for Verizon. "By continuing to deploy the latest technologies on our 4G LTE Advanced network, we pave the way for better and faster performance for the things our customers do now, and provide the groundwork for our future advancements."
New technologies pave the way
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
"These technologies produce record speeds for wireless technology and we are proud to be leading the way to commercialization with such strong partnerships," said Joakim Sorelius, Head of Product Area Network Systems at Ericsson.
"It is exciting to see Gigabit LTE momentum globally and in the U.S., especially as we move closer to a 5G world. With leading operators and infrastructure vendors like Verizon and Ericsson, we will continue to develop and deploy innovative technologies to power future networks and devices," said Mike Finley, SVP & President, Qualcomm North America.
What does this mean for consumers?
Verizon has been aggressively deploying the latest technological advancements on the nation's largest 4G LTE network to continue its industry leadership, to reach gigabit class speeds nationwide. Multiple devices in the market now support gigabit speeds.
