ZTE makes prototype smartphone call on China Unicom’s trial 5G network vs Huawei’s 5G NR @ 2.6GHz?

ZTE, which recently completed the 3rd phase of CMIIT IMT-2020 5G core network tests, just  announced it made the a 5G mobile call using its 5G prototype smartphone on the Guangdong branch of China Unicom’s trial 5G network in Shenzhen, China.  The trial was conducted in collaboration with China Unicom and involved placing a 3GPP Release 15 compliant New Radio (NR) non-standalone (NSA) mobile call using the prototype smartphone.  It used ZTE’s 5G end-to-end solution, including radio access network, core network, transport network and prototype device.   In addition to demonstrating a 5G call, the test verified key 5G technologies including Massive MIMO, 5G NR, non-standalone (NSA) dual connectivity, FlexE transport technology and 5G common core architecture (defined by who?).

 ZTE says “the future 5G system should be a unified network adaptable to different scenarios.”


“ZTE’s 5G solution has passed the end-to-end test in the three months after the release of the 3GPP Rel-15,” ZTE said in a statement.  “It showcases ZTE’s strong competency in 5G R&D and commercialization, demonstrating ZTE’s role as a reliable partner to global 5G operators and a key player in the 5G industry.”

Last year, ZTE announced a series of new-generation 5G base stations. The Chinese telecom and mobile phone vendor said that the new generation of 5G high/low frequency Active Antenna Unit (AAU) base stations support 3GPP release 15 “5G NR” NSA specification for the data plane.  The latest ZTE base stations combine the radio and antenna parts.  It is capable of integrating multiple frequency bands, which create what is known as the “AAU solution.” AAU supports 5G functions such as Massive MIMO and Beamforming.

Meanwhile, Huawei says it completed a 5G New Radio (NR) trial in the 2.6 GHz spectrum band.  Huawei said 2.6 GHz is one of the “excellent choices for operators to deploy 5G NSA/SA commercial network.”  The company noted that 2.6 GHz is an “abundant spectrum resource around the world, but not fully used in many areas.”  Huawei’s tests in the 2.6 GHz band follows earlier trials in the 3.5 GHz and 4.9 GHz bands.

The two Chinese telecom vendors are vying to take the lead in 5G testing under the jurisdiction of China’s IMT-2020 (5G) Promotion Group, which was established in 2013 as China’s platform to promote 5G research in that country. The 5G R&D trial established three separate phases for verifying a 5G solution: key technologies, technical solutions, and system networking.






ZTE Completes Multi-Scenario 5G Test; More to come this year

According to China Knowledge, An insider from ZTE said on social media that the company has completed what it claims was the first 5G call, internet and WeChat connection all in the same test.

The company completed the test using the same simulation system at its Shanghai R&D Center that it used to complete a 5G call with a prototype smartphone and CPE device in April. ZTE’s relevant R&D personnel said that the 5G tests conducted by ZTE have always been an end-to-end solution.

ZTE’s 5G solution covers fundamental patents, standards, communication rooms and base stations (signal emitters), chips (including Xunlong 1020), intelligent terminals (signal receivers), clouds, services and so on, which is the so-called core cloud tube end-to-end solution. In this way, the highly matched network and mobile terminals can bring better 5G experience to users.

As early as April this year, ZTE successfully made the first 5G phone call based on the 3GPP R15 specification (which will NOT be submitted to ITU-R for consideration as an IMT 2020 RIT) in Guangzhou. At the end of October, ZTE Mobile Phone and Data Terminal dialed the telephone signal in Shanghai R&D Center and formally completed the 5G call of the simulation system. A few days ago, The company achieved the 5G Internet access and WeChat 5G transceiver for the first time under the simulation system.

ZTE said it plans to conduct additional multi-scenario R&D tests in December, ahead of the planned launch of its first commercial 5G smartphone within the first half of 2019.

ZTE’s antenna-integrated solution supports full coverage from sub-6GHz to millimeter wave spectrum, including multiple combinations of carrier aggregation and N-DC (evolved-universal terrestrial radio access-new radio, a component of the 3GPP R15 5G standard).

The Chinese telecom equipment and mobile phone vendor has previously revealed plans to introduce experimental 5G customer premises equipment (what kind?) by the end of the year.

ZTE says it is conducting data service testing on 5G mobile phones and is expected to carry out 5G multi-scenario R&D testing in December. ZTE announced that it would launch commercially available 5G phones in the first half of 2019.

Huawei 5G “Wireless to the Home” Trial with Telus in Canada + U.S. Sales?

Huawei and Canadian telco Telus will work together on a trial for providing 5G wireless connectivity to residences in Vancouver, Canada. The companies will use tested millimeter-wave technology with 800 megahertz of bandwidth on the 28-gigahertz spectrum.

The end-to-end trial is based in the “5G Living Lab” — a downtown co-venture between the two companies — and conducted in the homes of Telus employees based in the city.

Officials said the system could provide 5G service similar to fiber networks while helping reduce operator costs and bolster accessibility. Initial trials conducted in December saw download speeds of more than 2 Gbps.

“This trial represents continued progress toward the launch of 5G as we start to replicate both the in-home experience and network footprint we will see when 5G becomes commercially available in the near future,” Telus CTO Ibrahim Gedeon said in a statement.

The latest trials are based on successful 3GPP-compliant millimeter wave specification tests conducted by the companies last June.  They operate with 800 MHz of bandwidth on 28 GHz spectrum and utilize Massive MIMO, F-OFDM, Polar Code and other technologies. The tests also use a specially-designed 5G Customer Premise Equipment unit and a 5G gNodeB built at the Living Lab.

The companies said the “Wireless to the Home” trial is believed to be the first of its kind in North America and among the first in the world.

“Millimeter wave technology will be an important tool in ensuring widespread deployment of 5G technology in Canada,” Huawei Wireless CTO Wen Tong said in the statement. “Huawei’s 5G solutions and terminals will enable 5G coverage over a neighborhood or small community cost-effectively, while providing more convenient and high-speed home broadband internet access services.”


Separately,  U.S. intelligence officials said “don’t use Huawei products” in testimony last week before the Senate Intelligence Committee.

“We’re deeply concerned about the risks of allowing any company or entity that is beholden to foreign governments that don’t share our values to gain positions of power inside our telecommunications networks,” FBI Director Chris Wray said. “That provides the capacity to exert pressure or control over our telecommunications infrastructure. It provides the capacity to maliciously modify or steal information. And it provides the capacity to conduct undetected espionage.”

NSA Director Michael Rogers added, “This is a challenge I think that is only going to increase, not lessen over time for us. You need to look long and hard at companies like this.”

Based on the information leaked out of the agency by Edward Snowden, the NSA conducted an operation dubbed Shotgiant, which resulted in U.S. intelligence operatives hacking into Huawei source code to conduct surveillance. As the New York Times reported in 2014, “The agency pried its way into the servers in Huawei’s sealed headquarters in Shenzhen…It obtained information about the workings of the giant routers and complex digital switches that Huawei boasts connect a third of the world’s population, and monitored communications of the company’s top executives.”

According to reporting, as well as the documents Snowden made public, the NSA hacked into Huawei’s networking equipment “so that when the company sold equipment to other countries–including both allies and nations that avoid buying America products–the NSA could roam through their computer and telephone networks to conduct surveillance.”

To put that another way, the agencies that conclusively hacked into Huawei equipment to conduct cyber espionage are warning against using Huawei equipment because it may be used by the Chinese to conduct cyber espionage.

In response to the Senate testimony, Huawei said in a statement that the company “is aware of a range of U.S. government activities seemingly aimed at inhibiting Huawei’s business in the U.S. market. Huawei is trusted by governments and customers in 170 countries worldwide and poses no greater cybersecurity risk than any ICT vendor, sharing as we do common global supply chains and production capabilities.”

Both Verizon and AT&T recently backed out of deals to sell Huawei mobile devices in the U.S.  Furthermore, there are bills in the House and Senate that would prohibit the U.S. government from using gear sold by Huawei and ZTE (the other major Chinese telecom equipment vendor).
