According to reporting in the Global Times, Purple Mountain Laboratories has achieved a communications transmission rate 10 to 20 times faster than speeds achieved by 5G wireless communications. The laboratory used frequencies in the 360 THz-to-430 THz band, frequencies associated with what eventually could become 6G wireless communications.
The newspaper reported that the high-tech laboratory in Nanjing, the capital of Jiangsu Province in China, used photonoic terahertz technology to generate terahertz signals through two higher-frequency lightwave beat frequencies. Terahertz wireless communications is considered to be the core technology of 6G networks, the newspaper reported.
“The achievement has a wide range of application prospects, according to Purple Mountain,” Global Times reported. “It can be integrated with existing fiber optical networks to expand 100-1,000 Gbps outdoor and indoor ultra-high-speed wireless access, replace the existing mobile network fiber optical networks to achieve rapid deployment, and replace the huge amount of cables in the data center to significantly reduce costs and power consumption.”
Global Times is an English-language newspaper published under the auspices of People’s Daily, an outlet of the Chinese Communist Party. Purple Mountain Laboratories is a Chinese government-backed institute.
The Hong Kong newspaper South China Post reported that China Mobile and Fudan University in Shanghai collaborated with Purple Mountain Laboratories in conducting the communications project. China Mobile is a state-owned company. Chinese company Alibaba owns South China Post.
Ericsson and Intel, together with China Mobile, have successfully demonstrated the first 3GPP-compliant, multi-vendor Standalone (SA) 5G New Radio (NR) call – accelerating the commercial deployment of standard-based 5G networks.
The 3GPP Release 15 5G NR SA specifications were completed on June 13, 2018 enabling Standalone 5G NR with user and control plane on a 5G next-generation core network. The Non-Standalone and SA releases share the same physical layer specifications. The successful interoperability test marks another milestone for the commercialization of the newly finalized 5G NR SA standards.
The partners have conducted live Interoperability Development Testing (IoDT) of 3GPP-compliant SA 5G NR technology at the Ericsson Lab in Beijing, China. The live IoDT operating at 100MHz on 3.5GHz mid-band used Ericsson’s 5G NR base stations and Intel’s 5G NR UE (Intel® 5G Mobile Trial Platform) prototypes.
Fredrik Jejdling, Executive Vice President and Head of Business Area Networks, Ericsson, says: “Successfully completing the first 3GPP-compliant Standalone 5G NR call marks another milestone with our ecosystem partners on the path to 5G commercialization, building on our years of research and standardization. Together, we’re delivering on our commitment to realize a standard-compliant and easily deployable technology that will bring benefits to our customers and end users.”
Asha Keddy, Vice President and General Manager Next Generation Standards, Intel, says: “Intel’s ongoing collaboration with Ericsson and China Mobile and our achievement of 3GPP-compliant Standalone (SA) 5G New Radio (NR) multi-vendor interoperability will help to prepare the industry for the deployment of 5G NR SA networks. As 5G networks begin to be deployed, a new wave of 5G experiences will be possible, powered by Intel technologies across the cloud, core network, access network, and devices.”
Huang Yuhong, Deputy General Manager of China Mobile Research Institute, says: “China Mobile has worked hard with global partners in setting up a common 5G SA standard. Now we have teamed up with Ericsson and Intel to achieve successful interoperability of 5G NR among multi vendors. This is an important milestone for the commercialization of 5G standards and will lay a solid foundation for China Mobile in our large-scale 5G trial, enabling the success of the global 5G industry.”
Later this year, Ericsson and China Mobile will conduct a 5G field trial in Suzhou city of Jiangsu Province, where the demo system will also be deployed and tested. Ericsson and Intel have been collaborating on 5G and jointly conducting trials globally with communication service providers since 2017.
Qualcomm Technologies, ZTE and China Mobile have achieved the world’s first end-to-end 5G NR Interoperability Data Testing (IoDT) system demonstrating a data connection based on 3GPP R15 standard. Following the guidelines of China Mobile, the IoDT connection demonstration took place at China Mobile’s 5G Joint Innovation Center, and utilized ZTE’s 5G NR pre-commercial base station and Qualcomm Technologies’ 5G NR sub-6 GHz UE prototype.
The end-to-end 5G NR system operates in the 3.5 GHz band and supports 100 MHz bandwidth, compliant with the 3GPP Release-15 5G New Radio layer 1 framework — including the scalable OFDM numerology, new advanced channel coding and modulation schemes, and the low-latency self-contained slot structure. The end-to-end 5G NR IoDT system is designed to efficiently achieve multi-gigabit per second peak data rates at significantly lower air interface latency than 4G networks.
“Implementation of 5G NR technologies will be critical to meeting the increasing connectivity requirements of emerging mobile broadband experiences such as streaming high-definition video and immersive virtual/augmented reality in the future, as well as enabling new high-reliability, low-latency services for autonomous vehicles, drones and industrial control, etc.,” said Cristiano Amon, executive vice president, Qualcomm Technologies, Inc., and president, QCT
The successful interoperable connection of the end-to-end 5G NR IoDT system serves as an industry milestone toward pre-commercialization of 5G NR technologies at scale, driving rapid development of 3GPP standards-compliant networks and devices.
November 15, 2016 — China Mobile and Huawei have rolled out several major network enhancements this year, strengthening network coverage and quality. In addition, the companies deployed a “2.3GHz TDD Massive MIMO solution” test and a “TDD + FDD 1Gbps Download Speed” test.
“Today’s real-time network tests demonstrated the ability of Massive MIMO technology and enhanced the efficiency and effectiveness of the TDD spectrum. The TDD+FDD carrier aggregation technology also brought higher surfing speed for fast growing numbers of mobile internet users,” Deng Tai Hua, president of the Huawei Wireless Network Product Line. Huawei is a strategic partner of China Moble, which owns a TD-LTE / LTE FDD converged network.
China Mobile also rolled out three major network enhancement projects this year, including growing the number of base stations, upgrading of the radio network system for quality enhancement at MTR stations, as well as boosting download speeds by adopting the latest advanced technologies, according to Sean Lee, CEO, China Mobile.
China Mobile worked with the MTR Corporation to deploy the LTE 2100MHz system in MTR stations, and the radio network system for MTR areas will be fully upgraded to provide LTE 2600MHz network coverage.
The number of base stations has been increased by 12 percent compared to the same period in 2015 and replaced core network equipment to build an advanced NFV core network. The company expects to upgrade 60 percent of its base stations by end of 2016 and 90 percent by second quarter of 2017. The overall infrastructure enhancement will lead to the deployment of Massive MIMO, 4×4 MIMO, downlink 256QAM and uplink 64QAM.
August 20, 2015 — In its first foray into VoLTE, Verizon has expanded to almost 4 million customers on what it calls Advanced Calling 1.0, David Small, EVP of wireless operations, Verizon Wireless Capital, said during the Oppenheimer Technology, Internet & Communications Conference, held Aug. 11, in Boston.
“Our call-in rate [to complain] on those customers is not any higher than what we would see from a non-Advanced Calling 1.0 consumer. And I do think they very much value that experience,” he said.
Small went on to say that the carrier has 100 people drive testing the VoLTE network, as well as system performance engineers working with the handset manufacturers and hardware providers to ensure overall network performance. He said the system has achieved a dropped call rate of .4 in half the time of previous network technology upgrades.
“So we feel very good about the service and we are testing it every day and having very good experiences,” Small said.
VoLTE Goes Global
Around the world, a number of contracts for VoLTE, as well as voice over Wi-Fi (VoWi-Fi), were signed in recent weeks.
China Mobile has signed a flurry of contracts to move its VoLTE aspirations forward. Alcatel-Lucent, which heretofore had only penetrated the United States with its VoLTE equipment, received a contract for its Rapport VoLTE communications software from what is known as the world’s largest telecom provider. It will the deploy platform in nine provinces, including Jiangsu and Zhejiang, as well as the cities of Shanghai and Chongqing.
China Mobile is also conducting a trial of Rapport as a network functions-based VoLTE solution. The deployment will also set the stage for China Mobile to offer VoWi-Fi.
Alcatel-Lucent wasn’t alone, thought. Huawei won nearly half of China Mobile’s VoLTE procurement project and was selected to be responsible for deployment of commercial VoLTE networks in the developed coastal provinces. ZTE Corporation said it too was a big winner securing large-scale orders for IP Multimedia Subsystem (IMS) core network solutions from China Mobile to enable the rollout of VoLTE services, including equipment and systems integration.
Elsewhere, Telenor Sweden has chosen Ericsson as the sole supplier for a full-scale upgrade of the operator’s core network, enabling VoLTE and VoWi-Fi to its customers. In Iceland, Síminn (Iceland Telecom) has entered into a five-year strategic partnership with Ericsson to further rollout of LTE across Iceland and eventually deploy VoLTE and VoWi-Fi. Under the agreement, Ericsson will be the prime supplier of all radio access equipment and the common core network, including the Ericsson IMS and Evolved Packet Core.
