ZTE and China Telecom deploy QCell 5G SuperMIMO solution

ZTE Corporation together with the Quanzhou Branch of China Telecom, have deployed the QCell 5G SuperMIMO solution in Quanzhou, China.

The Qcell 5G SuperMIMO solution can combine Super cell and MU-MIMO technologies, to adaptively perform multi-User Endpoint (UE) space division pairing. The solution is applicable to both digital QCell and traditional distributed antenna systems (DAS), which effectively solves the “interference” vs “capacity” tradeoff, while exponentially increasing user perception.

As the field test results show, the QCell super cell throughput is 1.07Gbps before SuperMIMO is enabled.  It reaches 2.2Gbps, 3Gbps and 4.05Gbps respectively after it’s been enabled. That greatly improves user experiences with 2 UE, 3 UE and 4 UE performing services at the same time.

In 2020, ZTE and China Telecom jointly launched the innovative 2.1GHz NR eDAS indoor distribution solution, which is the first 5G network performance improvement solution based on the traditional 2.1GHz NR indoor distribution system in the industry. The solution successfully overcomes the bottleneck of the traditional system.

SuperMIMO has developed into another innovative indoor distribution technology following the eDAS solution, thereby demonstrating the strength of the Quanzhou Branch of China Telecom and ZTE in the research and innovative applications of communication networks.

Moving forward, both parties will  be further committed to building high-quality 5G networks for their users through technical innovations.

  1. ZTE Corporation awarded Global Server Product Innovation Award 2021

    ZTE Corporation, a major international provider of telecommunications, enterprise and consumer technology solutions for the mobile internet, has been presented with the 2021 Global Server Product Innovation Award by Frost & Sullivan, based on the investigation and analysis of the 2021 global server product market, as well as the research and evaluation on mainstream server competitors within the industry.

    This award is to honor ZTE Corporation’s continuous innovation and progress in the global server product market, its technology leadership position in the industry, and its contribution to the overall development of the server industry.

    The reform of IT infrastructure is the engine of the digital transformation of enterprises. Regarding the rapid increase in data traffic in the era of the digital economy, enterprises’ IT infrastructures require stronger computing power to deal with the massive data. Meanwhile, due to differences in products and services and different application scenarios, each type of industry has also formed, diversified and customized needs.

    Opportunities and trends for server vendors
    Under this background, opportunities and challenges coexist for the server vendors. In terms of computing power, simply expanding data centers might help in dealing with data, but it also makes the data centers’ structure more complicated and harder to conduct operations and maintenance. Regarding this difficulty, companies and organizations require not only powerful data processing capabilities, but they also want more intelligent operations and maintenance, and simpler deployment methods of IT equipment.

    In terms of differentiated demands, servers, the infrastructure platform for enterprises’ IT systems, are required to respond to a large number of service requests and process services. In addition, companies and organizations in related industries have also proposed more differentiated requirements on performance, reliability, adaptability, and flexibility of servers.

    For instance, the financial enterprises rely on servers, storage and cloud operating systems to build a stable and reliable financial cloud platform; the telecom enterprises need to effectively assist customers in the reform of “network moving with the cloud” and “cloud and network integration”. The power enterprises require to ensure the power market safety and under control, and provide a stable and smooth operation environment for the national grid information system, etc. Products or services that can better meet the differentiated needs of various industries will stand out under the change.

    Following and setting the trends
    In the new era of servers becoming high performance, high reliability and diverse computing power, coupled with companies in related industries put forward higher requirements on the server performance, reliability, adaptability and flexibility. ZTE keeps up with the trends, constantly innovating technology and launching new products to meet new requirements:

    In the aspect of data processing, The G4X server newly introduced by ZTE uses 2 Intel Xeon third-generation extensible processors (Ice Lake) with a single processor up to 40 cores. Its performance is at the top level of the industry, providing an efficient engine for enterprises in the process of digital transformation.

    In the aspect of meeting the needs of multiple industries, ZTE G4X server boasts four to eight built-in heterogeneous and intelligent computing acceleration engines, which can satisfy the requirements of various scenarios of artificial intelligence, image processing and industrial control, etc.

    In the aspect of server reliability, ZTE G4X server can effectively meet the server reliability requirements of government, finance, railway, power grid and other enterprises. For instance, all ZTE servers are designed and produced based on telecom equipment standards. The reliability of the products is also verified by telecom product requirements, and can be efficiently adapted to the business environment of enterprises.

    In the aspect of environmental adaptation, ZTE adopts stringent standards for verification from R&D and design to producing and manufacturing. For example, to verify and improve ZTE G4X server’s reliability under high-stress environmental conditions, the server is tested at high and low temperatures ranging from 0 to 50 degrees. Moreover, to improve the protection capability of ZTE’s products in complex environments, ZTE uses a higher level of 6-8kV test standards. Furthermore, to identify extreme working conditions of products and continuously improve the product design, ZTE also conducts a HALT (High Accelerated Life Test) test.

    In the aspect of flexibility, ZTE G4X server realizes a flexible combination of “1 product, 2 chassis and 7 models” through modular design, effectively reducing O&M costs and deployment time for enterprise customers.

  2. US President Joe Biden on Thursday signed into law bipartisan legislation that will ban companies like Huawei and ZTE from getting approval for network equipment licences in the US.

    The legislation, Secure Equipment Act of 2021, will require the Federal Communications Commission (FCC) to adopt new rules that clarify it will no longer review or approve any authorisation applications for networking equipment that pose national security threats.

    Last year, the FCC formally designated Huawei and ZTE as national security threats, with that decision being made as the agency found that both companies had close ties to the Chinese Communist Party and China’s military apparatus.

    Since March, FCC commissioner Brendan Carr has made repeated calls for the legislation to be passed, saying at the time that the FCC has authorised 3,000 applications for Huawei networking equipment to be used.

    “Once we have determined that Huawei or other gear poses an unacceptable national security risk, it makes no sense to allow that exact same equipment to be purchased and inserted into our communications networks as long as federal dollars are not involved. The presence of these insecure devices in our networks is the threat, not the source of funding used to purchase them,” Carr said at the time.

    Besides Huawei and ZTE, other Chinese companies flagged as national security threats are Hytera Communications Corporation, Hangzhou Hikvision Digital Technology Company, and Dahua Technology Company.

    At the end of last month, the FCC also removed the authority for China Telecom to operate in the US, with the telco required to pack its bags and stop providing domestic and international services by the end of Christmas.

    Citing a recommendation from the Trump-era Justice Department, the Commission said China Telecom America “failed to rebut” a series of concerns raised.

    “China Telecom Americas, a US subsidiary of a Chinese state-owned enterprise, is subject to exploitation, influence, and control by the Chinese government and is highly likely to be forced to comply with Chinese government requests without sufficient legal procedures subject to independent judicial oversight,” the FCC said.

    With the US clampdown especially focused on Huawei, alongside other countries following suit, the Chinese tech giant reported a steep decline in its first-half revenue, with its business to the end of June reporting 320 billion yuan in sales, compared to 454 billion yuan at this time last year.

    In providing the financial results, rotating chair of Huawei Eric Xu said the aim of the company moving forward would be to survive sustainably.
