Editor's note: Huawei started to deploy 5G in 2009 and has entered its ninth year. In the past few years, Huawei's development speed has been staggering, and research on 5G has frequently achieved results that can be called milestones in the industry. To this end, we have specially combed Huawei's work in 5G.
At the 2017 MWC (World Mobile Communications Conference) conference, the four major communication equipment vendors - Huawei, ZTE, Ericsson and Nokia - have achieved great success in 5G. For the third consecutive year of the MWC conference, 5G has been in full swing from the original up-and-coming, and it is lacking in the continuous research and breakthrough of these major equipment manufacturers in the technical field.
Then, in this year's global environment, operators are rushing to follow the 5G commercial deployment and gradually push forward the 5G test. Let us also turn our attention to the four major communication equipment vendors in the world, and sort out their deployment and achievements in 5G over the years. Huawei is the world's largest communications equipment supplier. Let's start with this big inventory.
In 2009, Huawei took the lead in launching research and deployment of 5G technology. Lei Feng.com also learned that Huawei has specially established a proprietary domestic and foreign website for 5G in the past few years to communicate its 5G trends and news to the outside world. At the 2011&2012 MWC conference, Huawei's 5G technology was first revealed. At the meeting, Huawei demonstrated the 5G base station prototype Ultra-Node, at which time its download rate could reach 50Gbps.
And officially communicated to the industry to enter the 5G, we must count the official news released by Huawei in 2013. Huawei said it will invest at least $600 million by 2018 for research and innovation in 5G technology. The investment will focus on a range of key enabling technologies including air-to-air technology. This time, Huawei said that it is expected to realize the commercialization of 5G mobile networks from 2020. By then, the peak rate of mobile broadband users will exceed 10Gbps, which is 100 times faster than the current 4G network. This news caused widespread media discussion at the time. Later, a large number of enterprises took Huawei as the vane and joined the 5G camp.
Second, 2014-2016: Outreaching domestic and foreign operators continue to openIn fact, overall, in the early stage of Huawei's 5G layout, news related to this is rarely seen everywhere. However, since entering 2014, Huawei has begun to pull together the global operators and set up their sleeves to refuel, which may be closely related to its rapidly expanding foreign market strategy.
1. Foreign operators: mainly in Europe, the Middle East and Japan, the United States absent
United Arab Emirates
As a senior partner of Huawei, Emirates Telecom's fast-growing mobile broadband infrastructure has made Huawei feel excited. As a result, Huawei will officially open the first bullet of the operator outreach to the United Arab Emirates. At the beginning of 2014, the two signed a 5G cooperation MOU (Memorandum of Cooperation). And in October 2014, Huawei and Emirates Telecom jointly demonstrated three typical business scenarios of Huawei 5G technology at GITEX (Middle East International Communications and Consumer Electronics Information Exhibition): Smart sensors, MirrorSys (HD Vision) And Vehicular TelemaTIcs (autopilot), and 5G base station Ultra NodeTM prototype and "No Cell" access network architecture concept.
Russia: MegaFon
Huawei's second outreach of the United States has set its sights on our neighbors: Russia. In November 2014, Huawei and the Russian telecom operator MegaFon signed a 5G cooperation MOU (Memorandum of Cooperation), and the two sides indicated that they will cooperate to build a 5G experimental network for the 2018 Russia World Cup.
Japan: DOCOMO
When it comes to Japan's NTT DOCOMO (the largest mobile service provider in Japan), Huawei's cooperation with it is close. In March 2015, Huawei signed an agreement with the 5G field joint test in China and Japan to jointly verify the key technologies of the new air interface. The two will be combined in a unified air interface test in the frequency band below 6 GHz to verify the user data rate and 5G new air interface and algorithm under massive MIMO (MulTI-input MulTI-output: multiple input and multiple output). The so-called massive MIMO, also known as large-scale multi-antenna technology, is to install hundreds of antennas at the base station. The main technical principle is to introduce signals into the complex domain and realize multi-dimensional spatial mapping through high-order matrices.
Seven months after working with DOCOMO, Huawei conducted a large-scale 5G new airfield field validation. The 5G joint test is the first to carry out large-scale MU-MIMO (multi-user, multiple-input and multiple-out) technology field verification in the world. It can support 24 UE terminals simultaneously in the macro-cellular networking scenario of 5G core band below 6GHz. The test results show that compared with SU-MIMO (single-user multiple input and multiple output), the cell throughput rate of MU-MIMO technology can be increased by more than 10 times. Under 100MHz bandwidth, the average downlink throughput of single cell reaches 1.34Gb/s. The peak downstream throughput reaches 3.6Gb/s.
In November 2016, Huawei announced the 5G C-band large-scale field test with NTT DOCOMO to launch the world's first new air interface frame structure and system parameter specification that complies with the current 3GPP 5G NR. In the real deployment scenario of the macrocell dense urban area, the average total throughput rate reaches 11.29 Gbps, the peak spectrum efficiency reaches 79.82 bps/Hz/cell, and the one-way user plane delay is less than 0.5 milliseconds. This breakthrough result will have a major impact on the formation of the future 5G basic technology, and is another milestone in the joint testing of 5G field.
Turkey: Turkcell
The Middle East is also a 5G outreach force that Huawei cannot ignore. In July 2015, Turkish President Recep Tayyip Eldo visited China. He met with Huawei's rotating CEO Guo Ping and visited the exhibition hall of Huawei Beijing Research Institute. And on this itinerary, Huawei and Turkish operator Turkcell signed a 5G cooperation MOU.
Telefonica: Telefonica
In November of the same year, Huawei and the world's leading multinational operator Telefonica (Spain Telecom) signed a 5G strategic cooperation MOU in Hong Kong to jointly define 5G demand. Based on the MOU agreement, the two companies will jointly conduct a 5G network environment assessment and network architecture research to meet the application requirements of 5G networks for ultra-high speed and ultra-low latency. In June of the next year, the cooperation between the two went further. Huawei and Telefonica signed a 5G & NG-RAN joint innovation agreement in Shenzhen: will be user-centric wireless access in CloudRAN, 5G, and cooperate with 5G network reconfiguration and massive MIMO. .
Germany Telecom
Compared with operators in other European countries, Huawei and Deutsche Telekom have relatively more and more frequent cooperation. At the 2016 MWC conference, Huawei and Deutsche Telekom demonstrated the millimeter-wave user MIMO technology on the spot. This technology can provide ultra-high transmission rate of over 20 Gbps for single users, and the millimeter band can be used as a supplementary frequency band for low frequency bands. The experience of mobile broadband users. In this demonstration, the technology achieves a transmission rate of 70 Gbps on the 73 GHz millimeter band and achieves extremely high spectral efficiency.
At the same time, the two also demonstrated the world's first 5G end-to-end network slicing technology. The technology was developed and tested at Deutsche Telekom's 5G:haus laboratory in Bonn, Germany, with the aim of generating network slices on demand for the upcoming flexible 5G business scenarios.
United Kingdom: Vodafone
Like Germany, the depth of cooperation between BT and Huawei is not weak. In 2015, Huawei signed a 5G MOU with Vodafone, and in July 2016, the two signed a 5G accelerated memorandum of understanding. At the same time, Huawei teamed up with Vodafone to complete 5G microwave test in the UK. In this test, SU-MIMO with high-intensity physical reflection achieves a peak transmission speed of 20 Gbit/s for single-user equipment, and achieves a peak transmission speed of 10 Gbit/s for remote single-user equipment through MU-MIMO. This is the first time in the world to conduct outdoor field testing of 5G on E-Band microwave, and achieve single-user equipment to achieve peak transmission speed of 20Gbit/s, greatly improving high spectral efficiency. According to the International Telecommunication Union Radiocommunication Sector, 20Gbit/s is the transmission speed that 5G needs to achieve. The significance of this achievement is naturally self-evident.
In October of the same year, Huawei and Vodafone successfully conducted high and low frequency mobility tests in 5G dense urban areas. This is the first large-scale outfield mobility test conducted by the industry in the 5G real-world application scenario in dense urban areas. This test has gained: in the dense urban mobility environment, the 5G low-frequency C-band macro cell coverage reaches 1.5 kilometers, and the 5G high-frequency single-user average peak rate is higher than 5Gbps.
Looking at the long line of friendship events, it is not difficult to see that Huawei's cooperation with foreign operators is mainly in Europe, the Middle East, Central Asia and Japan, especially the three countries of the United Kingdom, Germany and Japan. The status of operators in the world is inseparable. However, as an extremely important part of the global communications industry chain, the United States and Huawei's cooperation in 5G technology presents a visually blank state, which is also intriguing.
