Ericsson and T-Mobile Work on LTE Optimization

Ericsson and T-Mobile are working together on a network evolution plan and optimization path to prepare the network for 5G, including 3GPP Release 13 and beyond.

Ericsson's Antenna-Integrated Radio (AIR) helped enable T-Mobile's rapid rollout of 4x4 MIMO and 256 and 64 QAM last year, which doubled peak data speeds. The next step is for T-Mobile to combine its spectrum holdings into one data pipe to enable Gigabit LTE speeds within the year. The plans also calls for LTE-U for bringing Gigabit LTE speed to more places.

Ericsson said it also provided 700 MHz tuning and optimization services, which enabled T-Mobile to adapt coverage, throughput and capacity to manage data traffic growth while ensuring high-quality service to its customers.

Neville Ray, CTO, T-Mobile, says: "T-Mobile's LTE network is the most advanced in the US and we'll continue to deploy the latest, global leading technologies that will create the foundation of a powerful 5G network built for mobility. We work closely with strategic partners like Ericsson to deliver the most advanced technologies that enhance our customers' experience."

Ulf Ewaldsson, Chief Strategy and Technology Officer, Ericsson, says: "Our work with T-Mobile has pushed us to find the highest-quality solutions for a growing and demanding subscriber base.  For example, our pioneering HD Enhanced Voice service for LTE and Wi-Fi last year improved audio quality and reliability for voice and music within calls. The bar gets higher each time, and we continue to push our own teams to prepare T-Mobile for its journey to 5G."

T-Mobile U.S. Deploys LTE-U

T-Mobile U.S. confirmed that it is now deploying LTE-U technology in its LTE network, following today’s FCC certification of equipment from strategic partners Ericsson and Nokia. The company anticipates introducing new network capabilities and devices for consumers this spring.

LTE- will enable T-Mobile customers to tap into the first 20 MHz of underutilized unlicensed spectrum on the 5GHz band and use it for additional LTE capacity. T-Mobile said it already has more capacity per subscriber than AT&T and Verizon, and the addition of LTE-U will only extend that lead and further improve the Un-carrier’s blazing-fast speeds. And, LTE-U will make it possible for T-Mobile to bring its forthcoming Gigabit LTE to more places across the country.

"T-Mobile’s network is second to none, with more capacity per customer than the Duopoly … and LTE-U will only accelerate our lead,” said Neville Ray, CTO at T-Mobile. “T-Mobile’s built a track record of introducing new innovations first, including deploying more LTE Advanced technologies than anyone in the US. All that innovation means one thing – a fantastic customer experience. That’s why T-Mobile customers are the most satisfied in US wireless!”

“We continue to push the boundaries of bringing new technologies in the unlicensed arena. Nokia is committed to working alongside T-Mobile to bring new solutions to market,” Ricky Corker, Nokia EVP and Head of North America said. “We stand ready to enhance T-Mobile’s leadership proposition and show what the future of mobile communications can be for Un-carrier customers."

Qualcomm Announces First Gigabit Class LTE Modem

Qualcomm introduced its sixth-generation discrete LTE multimode chipset -- the Qualcomm Snapdragon X16 LTE modem, which is built on a leading-edge 14nm FinFET process -- and the Qualcomm RF Transceiver, WTR5975 - the world’s first single-chip RF IC supporting Gigabit Class LTE, LTE-U and LAA with 5 GHz unlicensed band support.

The Snapdragon X16 LTE modem represents the first instantiation of Qualcomm's new, advanced modem architecture and is the first commercially announced Gigabit Class LTE chipset designed to deliver fiber-like LTE Category 16 download speeds of up to 1 Gbps.  It supports up to 4x20 MHz downlink Carrier Aggregation (CA) across FDD and TDD spectrum with 256-QAM, and 2x20 MHz uplink carrier aggregation plus 64-QAM for uplink speeds up to 150 Mbps.

Qualcomm said this new architecture will enable it to rapidly evolve its modem product line to address a wide range of connected applications, ranging from ultra-fast mobile broadband to power-efficient connectivity for Internet of Things (IoT) devices.

The Snapdragon X16 LTE modem also supports Licensed Assisted Access (LAA), the global standard for LTE in unlicensed spectrum, becoming the mobile industry’s first commercially announced LTE Advanced Pro modem. LTE Advanced Pro, beginning with 3GPP Release 13, marks an important next phase for 4G that will expand the technology into new applications and usage models, establishing the foundation for unified and more capable connectivity platforms into the next decade.

The Snapdragon X16 LTE modem is designed to reach Gigabit Class LTE speeds using the same amount of spectrum as Category 9 LTE devices. By using carrier aggregation and 4x4 MIMO, the Snapdragon X16 LTE modem can receive 10 unique streams of data using only three 20 MHz carriers. Its support for 256-QAM boosts the peak throughput of each stream from ~75 Mbps to ~100 Mbps, with additional gains possible with modem data compression. Additionally, with support for LAA as well as LTE-U, this combination reduces the amount of licensed spectrum required – to 40 MHz or less – to vastly expand the number of operators that can deploy Gigabit Class LTE speeds around the globe.

In addition to the advanced connectivity feature sets, the new modem and transceiver support Snapdragon All Mode, including all major cellular technologies (LTE FDD, LTE TDD, WCDMA, TD-SCDMA, EV-DO, CDMA 1x, and GSM/EDGE), frequency bands, Carrier Aggregation band combinations, LTE dual SIM, LTE Broadcast, HD and Ultra HD Voice over LTE (VoLTE) with single radio voice call continuity to 3G and 2G.

“In addition to serving as a significant milestone for the mobile industry, the Snapdragon X16 LTE modem is a powerful testament to Qualcomm Technologies’ continued technology leadership in all things wireless,” said Cristiano Amon, executive vice president, Qualcomm Technologies, Inc., and president, QCT. “Not only does the Snapdragon X16 blur the lines between wired and wireless broadband, but marks an important step toward 5G as we enable deeper unlicensed spectrum integration with LTE and more advanced MIMO techniques to support growing data consumption and deliver an even faster and smoother user experience.”

Sampling is underway and the first commercial products are expected in second half of 2016.

Ericssson: LTE Release 13 Brings Improvements

LTE release 13, currently under standardization in 3GPP,  will significantly increase user data
rates and overall capacity, as well as support new use cases and further strengthen LTE as a vital
part of future radio access, according to a new white paper published by Ericsson.

Some of the big improvements in LTE release 13 will include:

  • Licensed assisted access (LAA) -- which used unlicense spectrum to boost overall LTE network capacity. LAA targets operator-deployed small cells in the 5GHz band.  Initially, it will support downlink traffic although a later extension is planned for uplink traffic.
  • Carrier-aggregation enhancements -up to 32 carriers in both the uplink and downlink, compared to five with LTE Release 10.
  • Multi-antenna enhancements - two-dimensional base station antenna arrays with up to 64 antenna ports are being studied for exploitation of both the azimuth and elevation domain. 
  • Latency reduction


The Ericsson white paper also touches on machine-to-machine use case for LTE.

Alcatel-Lucent Pursues Wireless Unified Network Strategy

Alcatel-Lucent introduced a “Wireless Unified Networks” strategy which blends the upload and download capabilities of Wi-Fi and cellular technologies to enable higher capacity and give subscribers a more consistent and higher-quality mobile voice, data and video experience in high-traffic or low-signal locations.

As part of the new strategy, Alcatel-Lucent is introducing two separate capabilities: “Wi-Fi boost”, which uses cellular to enhance the performance of Wi-Fi networks; and “Cellular boost”, which uses unlicensed spectrum to enhance the performance of cellular. Combined, they maximize performance for subscribers across both access technologies.

Alcatel-Lucent’s Wi-Fi boost technology combines the downlink of Wi-Fi with the uplink of cellular. This capability requires an OS software update to existing user devices that are capable of both cellular and Wi-Fi transmission. It also requires software updates in the network to blend the Wi-Fi and cellular access networks into a unified network.  The company calculates that Wi-Fi boost can increase download speeds up to 70% and increase upload speeds by an order of magnitude or more (compared to standalone Wi-Fi at the cell edge), while also doubling the Wi-Fi range.  Commercial availability is expected in the second half of 2015.

Alcatel-Lucent will also add a cellular downlink to the Wi-Fi downlink of the Wi-Fi boost. This pre-standard LTE Wi-Fi Aggregation (LWA) implementation can more than double download speeds relative to standalone network capabilities.

Alcatel-Lucent’s Cellular boost leverages the unlicensed spectrum bands to enhance the capacity and performance of a cellular network. Plans include the introduction of new LTE-U and Licensed Assist Access (LAA) capable small cells.

“As an industry we have historically treated cellular and Wi-Fi as unique technologies. For example, the industry debates the merits of Voice/Data over Wi-Fi versus Voice/Data over LTE. From a consumer perspective, it should simply be Voice/Data over Wireless. With Wireless Unified Networks, we are excited to be taking the important steps to transform and greatly enhance the user’s wireless experience in the home, at work, and in dense venue networks by combining existing Wi-Fi and cellular networks into one high performance network,” stated Mike Schabel, Vice President of Small Cells in Alcatel-Lucent.

Alcatel-Lucent is also presenting its new multi-standard enterprise and residential small cells and compact metro cells at #MWC15. Other innovations on display include:
  • CloudBand management system, providing a fully integrated solution that orchestrates infrastructure, applications, and network in a single virtualized NFV platform.
  • Virtualized, massively scalable Mobile and Wi-Fi gateways, including enhanced evolved Packet Data Gateway (ePDG+) support and seamless concurrent use of cellular (licensed) and Wi-Fi (unlicensed) access connections to boost performance.
  • Virtualized IMS solutions that deliver a scalable and seamless communications experience across different access networks and devices.
  • Motive customer experience management and big network analytics that deliver a more consistent, high quality experience and provide insight into network, device and application performance across the network.

Ericsson Achieves 450 Mbps with LTE-U

Ericsson now has License Assisted Access (LAA), sometimes referred to as LTE-U, running live its labs.  The tests support the aggregation of licensed and unlicensed spectrum for peak rates up to 450 Mbps and enabling fair sharing of spectrum between mobile and Wi-Fi devices. The lab trials of both LAA fair sharing and licensed-unlicensed aggregation - 20 MHz on licensed band and 40 MHz on unlicensed 5 GHz band - were demonstrated from the Ericsson radio development units in Ottawa, Canada and Stockholm, Sweden.

LAA, or LTE-U, extends the benefits of LTE to unlicensed spectrum, providing reliable and predictable performance. The licensed band provides an anchor to ensure a seamless user experience with full mobility while the unlicensed band provides incremental capacity and enables faster data speeds.

The technology milestone has been achieved in cooperation with Qualcomm Technologies.  The companies also confirmed that Verizon, SK Telecom and T-Mobile US are already investigating the performance benefits that LAA can offer to mobile customers on their networks.

Starting in the fourth quarter 2015, Ericsson is adding LAA to its indoor small cell portfolio, including the Ericsson RBS 6402 Indoor Picocell (targeted at smaller buildings under 50,000 square feet) followed by the Ericsson Radio Dot System (for medium and large buildings).

Ed Chan, Senior Vice President, Network Planning, Verizon, says: "Verizon is committed to researching and adopting new technologies that will consistently improve the performance of our network and ultimately the experience we deliver to our customers. We are encouraged by the headway that Ericsson and Qualcomm Technologies have made in demonstrating the benefits LAA can provide."

Park Jin-hyo, Senior Vice President and Head of Network Technology R&D Center, SK Telecom, says: "SK Telecom is very active in the development of 5G technologies, which will be an extension and evolution of our LTE network. We are delighted to achieve the successful trial of the 450Mbps LAA and fair-sharing technology with Ericsson and Qualcomm Technologies and will continue to work closely with them to secure advanced network technologies."

Neville Ray, Chief Technical Officer, T-Mobile , says: "It is very encouraging to see License Assisted Access live in the Ericsson labs already delivering on the promises of both a better mobile broadband customer experience and the fair sharing and co-existence within the 5 GHz band among wireless and Wi-Fi devices. With over 500 MHz of underutilized spectrum in the 5 GHz Unlicensed National Information Infrastructure (UNII) band, LAA can provide our customers with superior network performance while effectively co-existing with other Wi-Fi devices to ensure a better experience for all wireless users."

Thomas NorĂ¯¿½n, Vice President and Head of Radio Product Management, Ericsson, says: "Carrier Aggregation was an important technology trend for mobile networks in 2014 and LAA is already set to be a key focus for mobile operators in 2015. Innovations like LAA that improve the user experience while increasing spectrum efficiency will be significant milestones that mobile industry leaders must both drive and support."
