Huawei announces 5G-oriented Discrete Spectrum Aggregation

Huawei released its 4.5G-based, 5G-oriented eLTE Discrete Spectrum Aggregation (eLTE-DSA) for energy utilities

Huawei said traditional narrowband solutions based on VHF (30 MHz to 300 MHz) and UHF (300 MHz to 3000 MHz) bands are flawed with low data rates, long latency, small capacity, which means they are unable to meet the demand for sustaining IoE growth.

Huawei has designed the eLTE-DSA solution to overcome the obstacles of traditional narrowband solutions and support IoE developments through leading advantages in Wireless Communications developed over the years.

By aggregating discrete narrowband resources, Huawei said its solution achieves access with an end-to-end delay as low as 20 ms and a huge capacity of up to 4,000 users in a single cell. The transmission rates reach kbpss to Mbps and the module power consumption is as low as 0.15W. This solution noticeably improves spectrum efficiency, capacity and performance of the networks, enabling the energy industry to move seamlessly towards 5G-oriented IoE. 

Eric Sun, President of Huawei Enterprise Wireless Business, said: "Going wireless will provide the foundation for the Internet of Energy. 4.5G technology will enable the Internet of Things, and 5G will accelerate the connection of people and things. With leading technological advantages in 4.5G and 5G, Huawei has successfully developed the 4.5G-based, 5G-oriented eLTE-DSA solution."

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."
