Verizon deploys LTE over CBRS spectrum

Verizon announced 4G LTE over CBRS spectrum (Citizens Broadband Radio Service) using its live commercial network in Florida.

The deployment uses a combination of Verizon licensed AWS and 700 MHz spectrum aggregated with 50 MHz of CBRS band 48 spectrum.  Verizon said it has achieved peak speeds of 790 Mbps using LTE Advanced features including multiple antennas, 256 QAM, and carrier aggregation across the shared and licensed spectrum.  The deployments in Florida involved outdoor and in-building systems.

Ericsson provided Ericsson Radio DOT system for indoor and Radio 2208 for outdoor, Qualcomm provided its Snapdragon TM 845 mobile test device with X20 LTE for access to CBRS on mobile devices, and Federated Wireless provided the prioritization through their Spectrum Controller, a Spectrum Access System (SAS) that dynamically allocates channels within the FCC’s spectrum sharing framework for this band.  Ericsson also provided the domain proxy to enable the radios to communicate with the Federated Wireless Spectrum Controller.

Commercial devices that can access the CBRS spectrum are expected in 2018.

Verizon said this real-world deployment marks the beginning of public access to the 150 MHz bandwidth of 3.5 GHz shared spectrum which until now has been used by the federal government for radar systems.

“As more people use more wireless devices to do more things in more places, building a network to stay ahead of customer demand is crucial,” said Mike Haberman, VP Network Engineering for Verizon.  “This shared spectrum resource is a critical component of our strategy to add capacity to our network.”

“We have been aggressively working over the past several years on deploying LTE Advanced features.  We’ve fully deployed carrier aggregation in our licensed spectrum across our network in over 2,000 markets, and have 4X4 MIMO and 256 QAM deployed in over 810 markets nationwide for our customers,” said Haberman.  “Combining those features with this shared spectrum band will provide more capacity, higher peak speeds and faster throughput when accessing the network for our customers who have come to expect the latest technology and highest reliability from Verizon.”

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.

IHS: LTE-Advanced Goes Mainstream

Barriers to deploying 4G are nonexistent at this point, and the main driver for 4G is the lower cost per megabyte of data, according to a survey of 24 global service providers that was conducted by IHS. 84 percent of IHS Markit’s service provider respondents are already running LTE‑Advanced (LTE-A) networks.

IHS said the most deployed LTE-Advanced feature among operator respondents is inter-band carrier aggregation, followed by enhanced inter-cell interference coordination and LTE‑Advanced coordinated multipoint.

The IHS survey also found that Voice over LTE (VoLTE) is exploding: three-quarters of those surveyed are offering VoLTE, up from just a quarter last year. This will not necessarily lead to imminent 2G or 3G shutdown, but 2G is rising on the agenda.  In addition, over 50 percent of respondents plan to deploy LTE in unlicensed spectrum (LTE-U) by 2018.

Ericsson and Bombardier test LTE at 200 kmh

Ericsson and Bombardier have completed trials of LTE networks for railway solutions at simulated speeds of up to 200 kilometers per hour with the goal of supporting communications-based train control (CBTC), closed-circuit television (CCTV), voice, platform information, advertising and Wi-Fi for passengers, and other such applications.

The companies said LTE could potentially be employed for CBTC, which uses high-resolution location determination and high-capacity data communications - such as those enabled by LTE networks - to support automatic train protection, operation and supervision functions.  In the CBTC tests, the LTE networks achieved uplink and downlink latencies far below the threshold of 100 milliseconds and packet losses approaching zero (anything less than 0.5% was considered a pass mark). Quality of Service capabilities built into Ericsson's equipment also allowed for the preemption and prioritization of mission-critical railway services.

Charlotta Sund, Head of Customer Group Industry & Society at Ericsson, says: "The results of the tests performed to date are very promising and we will continue to test a variety of modems to ensure we can provide robust LTE networks for rail applications. We aim to develop solutions that ensure enhanced rail safety through communications-based train control and CCTV, as well as enhanced entertainment for passengers through services such as voice, platform information, advertising and Wi-Fi."

Ericsson's 5G Software Plug-ins Extend LTE

Ericsson announced a number of 5G Plug-Ins, software-driven innovations that bring essential 5G technology concepts to existing LTE networks. Ericsson said LTE will continue to expand and evolve, addressing both an increased number of subscribers and their growing demands for extreme app coverage for data and video, as well as new low power wide area (LPWA) applications for the Internet of Things (IoT).  These include:

  • Massive MIMO Plug-In: Massive MIMO is the combination of Single-User MIMO (SU-MIMO) and beamforming supported by advanced antennas with a large number of steerable ports. Massive MIMO improves both the user experience and the capacity and coverage of the network. 
  • Multi-User MIMO Plug-In: building on Massive MIMO, Multi-User MIMO (MU-MIMO) transmits data to multiple user devices using the same time and frequency resources and coordinates beamforming. MU-MIMO provides a better user experience, enhances network capacity and coverage, and reduces interference.
  • RAN Virtualization Plug-In: RAN Virtualization improves network efficiency and performance by enabling Virtual Network Functions (VNF) to be centralized on a common platform supporting both 4G and 5G.
  • Intelligent Connectivity Plug-In: where 5G and 4G coverage areas overlap, Intelligent Connectivity enables the network to robustly anchor and intelligently route data based on application requirements and network resource availability, increasing the combined data throughput of 4G and 5G resources.
  • Latency Reduction Plug-In: this Plug-In shortens access procedures and modifies the frame structure to enable instant network access and more frequent transmissions. This in turn reduces time-to-content while enabling real-time communications for key 5G applications such as smart vehicles.

"5G will be driven by new use cases requiring higher performance - from connected cars with perfect driving records, to immersive augmented reality for remote surgery, to multi-K movies on mobile devices. 5G will unlock new consumer and industrial applications, and with our 5G field trial plans already well underway, we are now introducing Ericsson 5G Plug-Ins, which enable the evolutionary steps that operators need to take as they develop networks to secure their 5G future," stated Arun Bansal, Senior Vice President and Head of Business Unit Radio, Ericsson.

Ericsson Pushes Gigabit LTE and Hyper-Scalable RAN

Ericsson's next Networks Software 16B release will support 1 Gbps LTE user downlink rates and feature "hyper-scalable" radio access network (RAN) architecture. New Elastic RAN will harness interconnected basebands for optimal coordination throughout the network as a foundation in Cloud Radio Access Network (RAN) deployment. Ericsson is also adding to its Radio System portfolio with new microwave backhaul products and new access radios supporting 4x4 MIMO and 256 QAM.

Ericsson Networks Software 16B, which is slated for commercial release in Q2, will be showcased later this month at Mobile World Congress 2016 in Barcelona, Spain.  Key features include:

  • Three component Carrier Aggregation (CA) which enables the user to benefit from up to 60 MHz combined bandwidth from different spectrum bands simultaneously;
  • 4X4 MIMO (multiple input multiple output) which doubles the number of unique data streams being transmitted to the user’s smartphone, thereby enabling up to twice the capacity and data throughput;
  • LTE 256 QAM (quadrature amplitude modulation) encoding which packs more bits into the available spectrum; and
  • Ericsson Lean Carrier, which increases both the data throughput received by end users, and overall system capacity by reducing the interference caused by excess reference signaling across the LTE network.

Ericsson’s new Elastic RAN enables every Ericsson Radio System LTE baseband unit to coordinate with any adjacent one, whether in a centralized, distributed or hybrid network architecture using high-performance Ethernet transport networks.  Ericsson said this Elastic RAN approach ensures that capabilities such as Carrier Aggregation (CA) and Coordinated Multipoint (CoMP) can improve the user’s app coverage network wide irrespective of the baseband deployment scenario.

The Ericsson Radio System, which launched in Q1 2015 and became generally available in Q3 2015, is now complemented with three new radio access products supporting 4X4 MIMO as well as new spectrum bands and spectrum re-farming:

  • Radio 4415 with 4x40W output power supports 4x4 MIMO to increase capacity by doubling the available data streams
  • Radio 2012 adds support for the 1.4 GHz Supplemental Downlink band, thereby adding capacity to the network
  • Radio 2212 with 2x80W output power to facilitate spectrum re-farming as operators upgrade from 2G to 3G and LTE

New microwave additions to the Ericsson Radio System include:

  • MINI-LINK 6651, a compact indoor unit with a link capacity of 1.9 Gbps (using 4096 QAM and a 112 MHz channel), which is used for split mount deployments using an outdoor radio unit.
  • MINI-LINK 6354, a two carrier all outdoor solution for traditional frequency bands, providing a capacity of 2.8 Gbps (using 4096 QAM and 112 MHz channels).
  • Multi-band Booster, which provides a significant boost in performance and improved use of spectrum, by combining a wider high frequency channel with a narrow low frequency channel. One example is bonding of an E-band microwave radio, (70 and 80 GHz) together with a radio using a channel in the 23 GHz to enable 10 times more capacity than 23 GHz alone.
  • High Performance Compact antennas for the current MINI-LINK 6363, MINI-LINK 6352 and Fronthaul 6392

"Our latest combination of software, hardware and network architecture innovations supported on the Ericsson Radio System, ensure that our mobile operator customers can continue to delight their customers while driving network performance and efficiency improvements as they evolve to 5G. Gigabit LTE, Elastic RAN, and new radio access and microwave backhaul products are all designed to help our operators become the frontrunners in their markets,” stated Arun Bansal, Senior Vice President and Head of Business Unit Radio, Ericsson.
