MTS activates Licensed Assisted Access (LAA) in Russia

MTS, the leading communications service provider in Russia and the CIS, deployed Licensed Assisted Access (LAA) technology at a shopping center in Ufa City, Russia.

The service activation took place in the Planeta shopping center in Ufa on May 17 following a series of tests conducted on a live MTS network using a commercial smartphone.

The new LAA network in Ufa aggregates a 20 MHz band in the 1800 MHz licensed LTE spectrum (4x4 MIMO, 256-QAM) and three 20 MHz bands (2x2 MIMO, 256-QAM) in the 5 GHz unlicensed spectrum. The installation is built on Ericsson’s ERS indoor small cell stations using 1800 (2212) and LAA (2205) broadband radio modules, while Motorola Moto Z2 Force smartphone powered by the Qualcomm Snapdragon 835 Mobile Platform was used as a smartphone.

The Snapdragon 835 integrates X16 LTE modem, the first commercial modem supporting the LAA technology. The configuration yielded downlink speeds of 979 Mbps.

This marks the first commercial LAA rollout in the region. Qualcomm is also listed as a technology partner.

Andrey Ushatsky, Vice President, Technology and IT, MTS, says: "With the launch of the commercial high-speed LAA-network in cooperation with Ericsson and Qualcomm Technologies, MTS again confirms its status of a technological leader. This is the first LAA network in Russia and Eastern Europe and an important milestone on the way to 5G. LAA will allow us to build gigabit LTE networks quickly and cost-effectively in places with active traffic consumption, where operators do not always have enough available frequencies in the licensed spectrum.”

Yulia Klebanova, Vice President of Business Development, Qualcomm Europe, Inc., says: "We are happy to see Gigabit LTE network services becoming available to the subscribers of MTS. Gigabit LTE can help operators increase network throughput and achieve higher spectral efficiency, providing incredible network speeds to users of mobile devices powered by the Qualcomm® Snapdragon™ Gigabit LTE modems with LAA support, including Snapdragon 835 and 845 Mobile Platforms.”

Sebastian Tolstoy, Head of Ericsson Russia, says: “LAA gives service providers access to new spectrum, increasing network capacity and supporting both higher peak rates and higher-than-average speed rates. This commercial LAA rollout marks another important milestone in our strategic cooperation with MTS. Earlier we achieved peak throughput data rates of 25 Gbps at our joint 5G trial. The next step is to prepare for a new demonstration of enhanced 5G capabilities during the football tournament in Russia this year.”

Nokia and T-Mobile hit 1.3 Gbps with Licensed Assisted Access

T-Mobile has hit download speeds of 1.3 Gbps using Nokia's commercial Licensed Assisted Access (LAA) technology.

The high-performance was achieving using 14-layer transmissions during tests conducted at T-Mobile's lab in Bellevue, Washington. The tests employed an Nokia AirScale Micro RRH connected to an AirScale system module. Speeds of 1.3 Gbps were achieved by aggregating LTE carriers in licensed and unlicensed bands using five-component carrier aggregation, 256QAM, 4x4 MIMO and LAA on 14 antenna layers.

Neville Ray, chief technology officer at T-Mobile, said: "We are working to deploy small cells that support LAA and build on the LTE-Advanced features we've deployed across the country, laying a foundation for 5G. Our priority is ensuring customers have the best mobile experience, so we are accelerating LAA and five carrier aggregation to give them even higher speeds and greater network performance."

Marc Rouanne, president of Mobile Networks at Nokia, said: "Nokia is providing a path towards 5G that allows operators like T-Mobile to attain gigabit speeds with LTE by leveraging all available licensed and unlicensed spectrum. With LAA, we are helping T-Mobile gain higher download peak rates than could be achieved with licensed spectrum alone. This adds capacity beyond the spectrum licensed to this operator, and the existing network sites are used with limited TCO investment."

T-Mobile and Ericsson push Licensed Assisted Access to 1.1 Gbps

In a demo conducted at  T-Mobile's lab in Bellevue, Washington, T-Mobile and Ericsson achieved speeds of 1.1 Gbps using 12-layer Licensed Assisted Access (LAA) technology.

The set-up sued Ericsson's Radio System and the TM500 network test equipment from Cobham Wireless. The test combined several LTE technologies including 256 QAM, 4x4 MIMO, and LAA by aggregating two licensed carriers and three unlicensed carriers.

The Ericsson Radio 2205 delivers LTE on the 5GHz unlicensed band in outdoor micro cell environments. Using LAA, the unlicensed carriers can be aggregated with licensed carriers on the micro cells or on nearby macro cells.

The companies claim this to be the first demo in the world to hit speeds beyond the 1 Gbps threshold on unlicensed spectrum.

“Breaking the 1 Gbps-mark means that commercial gigabit speeds are not far from reality for many broadband users, with our LAA and MIMO technologies as key enablers. It is also an example of how innovatively we work with partners to push the boundaries of technology and achieve new milestones,” said Fredrik Jejdling, Executive Vice President and Head of Networks at Ericsson.

Neville Ray, Chief Technology Officer for T-Mobile, says: “T-Mobile has built the nation’s fastest LTE network by innovating and bringing new technologies to market for our customers. This LAA technology builds upon our deployments of 4x4 MIMO and 256 QAM and will give customers even greater access to near gigabit speeds in 2018.”

Ericsson: commercial gigabit services within reach with LAA

Ericsson provided a quick update on its activities with Licensed Assisted Access (LAA), a technology which it says will enable commercial gigabit services in the near future.

LAA allows operators to use unlicensed spectrum in combination with their licensed spectrum. The technology is designed to co-exist with other unlicensed spectrum technologies such as WiFi via a feature termed 'listen before talk', which allows fair coexistence between LTE-LAA and WiFi.

Recently, Telstra, in partnership with Ericsson and Qualcomm, became the first carrier to launch a commercial Gigabit LTE network. The gigabit downlink performance is enabled by LTE Advanced features including 4x4 MIMO, 3CA (Three Carrier Aggregation) and higher order modulation (256QAM). On the uplink, Telstra's new network capability uses 64QAM and 2CA (Two Carrier Aggregation) for a peak upload speed of up to 150 Mbps. NETGEAR's Nighthawk M1 Mobile Router (MR1100) leverages 4x4 MIMO and is equipped with the Qualcomm Snapdragon(TM)  X16 LTE modem.

In June, AT&T and Ericsson conducted a live LTE-LAA technology field trial, during which initial wireless data rates of more than 650 Mbps were achieved in downtown San Francisco.

Also in June, T-Mobile completed the nation’s first mobile broadband data session live in the field using License Assisted Access (LAA) on its commercial network.

Italian operator TIM has achieved speeds of nearly 1Gbps on its live advanced 4G network in Milan using Ericsson’s LAA technology.

Ericsson, Verizon and Qualcomm achieved a speed of 953 Mbps in a joint commercial network deployment in Boca Raton, Florida. This is the fastest announced speed leveraging LAA technology achieved in a real-world, dynamic network environment in the US.

South Korean operator SK Telecom  and MTS, the largest mobile network operator in Russia, have all recently completed their own LAA trials.

Ericsson introduced its micro Radio 2205 for LAA. Designed for unlicensed spectrum use, Ericsson’s micro solution provides small dimensions, flexible mounting and superior performance. Qualcomm Technologies provided a Qualcomm Snapdragon 835 mobile platform device, with Gigabit LTE capability thanks to the integrated Snapdragon X16 LTE modem.

Verizon, Ericsson and Qualcomm Demo LAA at 953 Mbit/s

Verizon announced that in what is believed to be a U.S. wireless industry first, it has partnered with Ericsson, and Qualcomm Technologies, a subsidiary of Qualcomm, to demonstrate a mobile data rate of 953 Mbit/s in a joint commercial network deployment in Boca Raton, Florida.

Verizon noted that while lab tests have achieved comparable speeds in recent demonstrations, this is the fastest speed announced to date that has been achieved in a real-world, dynamic network environment leveraging Licensed Assisted Access (LAA) technology.

The demonstration utilised commercially available Verizon network components including a cell site, hardware, software and backhaul, with Ericsson providing the advanced remote radio head. The Ericsson micro Radio 2205 for LAA, designed for unlicensed spectrum use, is compact, provides for flexible mounting and is a component of the Ericsson Radio System, an end-to-end modular radio network portfolio of hardware and software designed for any site type and traffic scenario as networks transition towards 5G.

In addition, for the trial Qualcomm Technologies provided a Qualcomm Snapdragon 835 mobile platform test device equipped with Gigabit LTE capability leveraging the integrated Snapdragon X16 LTE modem.

Verizon stated that the latest demonstration used a combination of the latest 4G LTE wireless technologies to deliver the higher mobile speeds. Technology employed included carrier aggregation, which enables multiple spectrum channels to be combined to allow data to be carried more efficiently and faster peak speeds.

Verizon noted that it was the first U.S. carrier to launch LTE Advanced with two channel carrier aggregation nationally last year, and has subsequently completed the deployment of three channel carrier aggregation using its licensed spectrum.

To achieve latest near-gigabit mobile speeds, Verizon used a combination of licensed and unlicensed spectrum for the first time. The four carrier aggregation utilises LAA to combine its spectrum holdings with unlicensed spectrum via home and commercial WiFi connectivity.

The demonstration with Ericsson and Qualcomm Technoogies also involved technology including 4 x 4 MIMO, which uses multiple antennae at the cell tower and on consumers' devices to optimise data rates, 256QAM, allowing customer devices and the network to exchange information in larger amounts and thereby to deliver more bits of data in each transmission.



  • Recently, AT&T announced that it had achieved mobile speeds of 650 Mbit/s using LTE and LAA technology in a field trial working with Ericsson, while T-Mobile announced it had demonstrated 741 Mbit/s mobile data rate in a field trial of LAA technology.

Liberty Global and CableLabs Join the MulteFire Alliance

Liberty Global and CableLabs have joined the MulteFire Alliance, an independent, diverse and international member-driven consortium dedicated to developing next-generation wireless technology. customers.”

The main focus of the MulteFire Alliance is to ensure that next-generation LTE mobile standards are compatible with shared and unlicensed spectrum. This compatibility ensures that the next generation technology is more widely available and that it can coexist alongside Wi-Fi and other technologies. What also makes this technology unique is that operators without access to the licensed spectrum still will be able to use it, breaking down barriers to entry and opening the door to greater innovation.

“This step will arm the cable industry with a new wireless technology that builds on our success in providing Wi-Fi and mobile services and complements the industry’s fixed broadband technology leadership,” said Ralph Brown, CTO of CableLabs.

Currently, the MulteFire Alliance is working to adapt 3GPP-based mobile wireless standards for shared and unlicensed spectrum so that the technology is broadly available and fairly coexists with Wi-Fi and other technologies. MulteFire is based on 3GPP Release 13 License Assisted Access LTE (LAA) and Release 14 enhanced LAA (eLAA), which uses Listen-Before-Talk (LBT) etiquette to share spectrum in a manner similar to Wi-Fi.

Unlike LAA, however, which is anchored to licensed spectrum and must be used in conjunction with a mobile network, MulteFire will operate entirely in unlicensed or shared spectrum, so that operators without licensed mobile spectrum can utilize it. This “standalone” functionality has been proposed in the 3GPP standards body for both LTE and 5G. By building this capability in the Alliance, its member companies will enable its adoption in global standards and the corresponding broad benefit of wireless innovation.

“We appreciate that the Alliance is committed to transparency and collaboration, given the importance of unlicensed spectrum to broadband access,” said Rob Alderfer, vice president of technology policy at CableLabs. “As we move toward ever greater sharing of scarce spectrum resources, reliable coexistence across technologies is essential as we continue to innovate. It’s what we believe is the most critical aspect of the Alliance, and one that will be important as the industry moves toward 5G standards.”
