Huawei and China Telecom implement 5G Super Uplink

China Telecom Shanghai announced the implementation of a 5G Super Uplink solution featuring TDD/FDD coordination, high-band/low-band complementation, and time/frequency domain aggregation. Super Uplink, which is supported from end to end by Huawei 5G technologies, was first announced by the partners at this year's Mobile World Congress in Barcelona

The 5G Super Uplink implements the time-frequency domain aggregation of TDD and FDD in the uplink frequency band. This increases uplink spectrum resources of NR, boosts the uplink capability of the 5G network, reduces latency, and improves the utilization rate of the uplink spectrum of 2.1 GHz/1.8 GHz.

The companies said the newly launched Super Uplink solution increases uplink speeds by 20%–100% under good radio conditions, while also delivering a fourfold increase to cell-edge uplink rates.

China Telecom Shanghai plans to expand pre-commercial trials and increase research and development, network construction, and industrial cooperation.

Embracing MEF LSO APIs for Better, Automated Customer Experience

MEF Annual Meeting – July 2019, Shawn Hakl, SVP of Business Products, Verizon, shares his excitement about MEF’s work in standardizing LSO (Lifecycle Service Orchestration) that enable end-to-end orchestration of services across service providers and over multiple network technology domains. He is particularly excited about the potential impact of LSO Sonata API adoption for inter-provider service automation.

“We just came out of a pretty exciting Board Meeting about the progression of LSO standards at MEF. I think people should be really excited about what’s coming. I think there’s a lot more clarity on the use cases and how carriers will adopt this technology and how it will meaningfully impact our customers.”

“Where the network orchestration component comes in is how what was previously done manually or with physical settings in the equipment can now be done through automation. Network orchestration is the technology that will allow us to integrate functions and deliver outcomes through the network. And it allows for interoperability of functions between each other – the interoperability between carriers – and really builds the basis for what our customers are asking for:  a fully automated experience controlled through a software-based implementation.”

“So, what’s exciting about the work with LSO Sonata is that you’ve actually seen multiple carriers implement it…What we all recognize as an industry is that if we continue to have to invest in automation between functions at an individual, piece-by-piece fashion for every function and every NFV it is going to be incredibly inefficient and get in way of the experience.”

“Now, really there is a compelling case for the carriers to standardize the implementation across the board and drive a lot of value for our customers.”

Dell'Oro: Worldwide telecom equipment market up 6%

The worldwide telecom equipment market grew 6 percent year-over-year (Y/Y) in the past twelve months, according to a new report from Dell'Oro Group.

The majority of growth was driven by Mobile RAN and Optical Transport sales. Equipment manufacturer revenue in these two technology areas grew 10 percent and 8 percent, respectively.

The telecom equipment market shifted into a growth phase in 3Q 2018 after three years of decline. As a result, the market’s growth for the trailing four-quarter period ending 2Q 2019 was up significantly from a bottom reached in 2017. Most of the leading vendors gained revenue during this period with the highest percentage increases obtained by Samsung, ZTE, and Ciena.

Although Huawei was placed on the U.S. Entity List in late May, restricting its purchase of U.S. components without a license, the company seems to have avoided any negative impact on sales of telecom equipment. For the trailing four-quarter period (3Q18 through 2Q19), Huawei held the highest share of the telecom equipment market at 28 percent.

Nokia captured the second-highest share in the period due to its strong position in each of the seven technology segments included in the Telecom Equipment Market report. Nokia was a top 4 vendor in each product category.

Huawei updates its 5G progress

Huawei Technologies issued the following update regarding its 5G momentum:

  • 50 commercial contracts signed to date
  • 28 contracts from Europe, 11 from the Middle East, 6 from Asia-Pacific, 4 from the Americas, 1 from Africa
  • 200,000 5G base stations shipped to date
  • As of June 2019, HUAWEI CLOUD and its partners have opened 23 regions with a total of 44 availability zones, and launched over 180 cloud services and 180 solutions.
