3HK completes Hong Kong’s first outdoor 5G trial

3 Hong Kong has revealed it has completed of 5G outdoor network trials in the 3.5-GHz and 28-GHz spectrum bands.

The company said it believes it was the first mobile operator in Hong Kong to complete a live outdoor 5G trial broadcast. The test was conducted at a trial cell site in Causeway Bay.

3 Hong Kong received an indoor 5G test permit for the 3.5-GHz band in August 2017, and completed a number of initial trials by the end of that year. In May, the company secured a temporary permit to conduct 5G trials in the 26-GHz and 28-GHz millimeter wave bands.

Another temporary permit for outdoor and indoor trials in the 3.5-GHz band was granted in June, and the company achieved 2Gbps network speeds during an earlier trial using 100MHz of spectrum in this band.

3 Hong Kong said the test results indicate that 3.5-GHz band coverage – when used in conjunction with Massive MIMO, can be comparable to the coverage afforded over LTE using the 1800-MHz band.

The design of 5G networks will use a combination of mid-band spectrum such as 3.5-GHz for a wider coverage area, and millimeter wave spectrum for high speeds

“3 Hong Kong took the initiative to carry out end-to-end trials in various 5G bands in preparation for a new era of mobile communications,” commented Kenny Koo, CEO of 3 Hong Kong’s parent company Hutchison Telecommunications Hong Kong Holdings.

“We welcome the government’s decision to allow various of its premises to accommodate 5G base stations, and we hope the application and approval processes can be simplified and accelerated to help Hong Kong’s 5G development.”

NTT DoCoMo achieves 28GHz wireless data transmission in ultrahigh mobility environment

NTT DoCoMo says it has achieved what is believed to be the world’s first successful 28 GHz wireless data transmission between a 5G base station and a 5G mobile station in 5G field trials using a car moving at 305 KMH or about 189 MPH. The trials were conducted last month at the Japan Automobile Research Institute (JARI) using 700 megahertz of spectrum. They also included live wireless relay of 4K high-frame rate video via uplink from a 5G mobile station moving at 200 km/h, according to DoCoMo.

The speeds in the field trials are designed to be similar to speeds of high-speed railways, so it’s understandable the operator wants to make sure it works, including handoffs, at these kinds of speeds.

Working with NEC and Nippon Telegraph and Telephone Corporation (NTT), DoCoMo said the trials also achieved what are believed to be the world’s first successful 1.1 Gbps ultrahigh-speed data transmission via downlink to a 5G mobile station moving at 293 km/h. It also conducted a fast handover during communication between 5G base stations and a 5G mobile station moving at 290 KMH.

DoCoMo noted that the “world’s first” achievements are according to DoCoMo research as of April 23, 2018. Japan’s largest wireless network operator and its partners used beamforming and beam tracking to address propagation challenges in the 28 GHz band. The 5G base stations used massive-element antenna (96 elements, up to two beams), and the mobile station had massive-element antenna (64 elements, up to two beams). Sony Business Solutions provided a 4K camera for high-frame rate video, and DoCoMo’s own Dandelion racing manager provided a trial car and operated the car on the test course.

DoCoMo’s 5G R&D objectives and “Phantom Cell” architecture:

NTT DOCOMO’s 5G related research and development will enable a wide range of capabilities such as super high data rate communications of over 10Gbps, lower latency, and simultaneous connection of a large number of terminals in order to support the future spread of M2M communications and internet of things (IoT), etc.

DOCOMO is advocating the concept of Phantom Cell architecture, which consists of a combination of a small cell using a higher frequency band and broader bandwidth and a macro cell using a conventional lower frequency band. For 5G, DOCOMO is making research and development efforts with a focus on the development of technologies that enable efficient transmission in higher frequency bands such as the beamforming technology leveraging a large array of antenna elements (Massive MIMO) as well as technologies for efficient transmission in lower frequency bands.
Toward the goal of 5G service rollout, various mobile communication technologies and schemes need to be tested, including low-latency transmission methods that meet the needs of M2M and other various applications. To this end, DOCOMO is conducting experimental trials in collaboration with world-leading vendors to confirm the feasibility of a wide range of mobile communication technologies, centering on the concepts that DOCOMO advocates.

Huawei and NTT Docomo “5G” mmWave Field Trial in Tokyo

Huawei is highlighting a Tokyo, Japan trial in which the Chinese telecom/IT vendor achieved “5G” like download speeds of 4.52 gigabits per second over ~ three-quarters of a mile using 28 GHz millimeter-wave wireless technology.  The trial took place in downtown Tokyo, where a base station working over 28GHz frequency was located at Tokyo Skytree’s viewing deck, 340m above the city.

Working with Japan’s NTT Docomo, Huawei said it was confident of launching a commercial 5G rollout by 2020 (NOTE: the IMT 2020 set of 5G standards are to be finalized by year end 2020).

“The high-speed and long distance support is one of important technical challenges for 5G mmWave conditions. This successful long distance live-demo on a 5G mmWave is a groundbreaking achievement in our joint effort with NTT DOCOMO to build a fundamental 5G commercial environment. This success makes us more confident in realizing the goal of commercializing 5G by 2020,” said Gan Bin, vice president of Huawei’s 5G product line.

Huawei utilized its 5G base station for the test, which supports Massive MIMO and beam forming technologies. Huawei also provided the 5G core network and the 5G mm wave test user equipment.

Huawei anticipates conducting further testing at the world’s biggest 5G testing site in Beijing’s Huairou District.

The test comes amid a flurry of 5G testing and trials around the world.  For example, BT and Nokia announced plans for live “5G” tests in the UK earlier this month.
