'4.5G has two of the greatest value, one is to meet the operator's current user experience upgrade demands, 5G really come to a certain period of time, after the completion of the standard to go through the industrial chain mature and scale construction; the second is to hatch the future , By 2025 the world will have more than 100 billion connections, in order to meet the whole connected to the world, to participate in the digital process of all walks of life, operators must now start to cultivate their team, ecosphere, commercial construction and other aspects of the capacity. Will be the industry to 5G the only way, and will be in the future for a long period of time with the 5G coexistence; and Huawei proposed 4.5G purpose, that is, leveraging operators in the commercial success. On the Institute of a media exchange, Huawei wireless network R & D president should be the face of the C114 said.
In the mobile phone design, function more and more homogeneous today, the network experience is gradually becoming the focus of consumer chase. Not only for Samsung, millet in this year's flagship machine, also announced to support 4x4 MIMO technology.
'4x4 MIMO from the consumer understanding point of view, is the download rate can be increased by 2. For example, now 1080P video has been in Youku and other video sites become mainstream, in the indoor this weak coverage scenario, 2 antenna receiving antenna may only Can watch 720P and below video, but 4 to receive the antenna phone can watch 1080P; everyone playing the king glory of this kind of combat game or in the red pack, who is higher speed, smaller delay, it is easier Gain the advantage.
On the network side, the 4x4 MIMO corresponds to the 4T4R - which is both a key feature in 4.5G and will be the starting point for the 5G network, which is generally ahead of the terminal and 4T4R On the LTE network standards, the global mainstream operators will be one of the important direction of the evolution of the network as of July this year, only Huawei has been deployed for the operators of the 68 4T4R network, Wembley Stadium, the EE network Test 4T4R technology is applied.
'Spectrum is not a source of resources, in some countries the spectrum is also very expensive, then how to maximize the efficiency of the limited spectrum?' 4T4R role is mainly reflected in the spectrum efficiency and the resulting increase in capacity - Compared with LTE, the downlink capacity can be increased by 1.2-1.8 times, the uplink capacity can be improved 1.25 times, so as to fully support the outdoor hot spots, large venues and families and other scenes on the network capacity requirements from the operator point of view, the deployment of 4T4R can be achieved from the district The center to the edge of the experience to enhance the area; can be achieved from the peak rate to the average capacity of the experience to enhance; but also from outdoor to indoor experience to enhance, allowing users to feel seamless full scene high speed Internet experience.
More importantly, due to the significant improvement in user experience, 4T4R can be in a complex environment for operators in the business and brand on the breakthrough.To Turkey Mobile (Turkcell), for example, the operator and Huawei April 1, 2010 officially released 4.5G commercial network, completed in January 4T4R scale deployment, within six months of monthly user usage (DOU) growth rapidly, compared with the same period increased by 63%, data business revenue grew 97% Ranked first in the Turkish operator, and this year won the P3 test Turkey's first success.
Coach, True Move and Huawei in 2016 together to deploy the world's largest 4T4R network, the total size of more than 6300 sites. True network statistics show that compared to traditional 2T2R network, 4T4R cell average throughput increased by 20%, while the district Edge throughput increased by 40% to help True in the Thai mobile operations competition to seize the initiative, released within one week after the stock price rose 20%; today, True has become the country's second largest mobile operator.
'This year is the rapid development of 4T4R industry chain year, Haisi, Qualcomm, Intel's mainstream chips have already supported 4x4 MIMO, in addition to Huawei, Samsung, Sony, millet, etc., follow-up will be more and more brand mobile phone will 4x4 MIMO as a standard, both in the low-end models will have this feature by default, the network Ready plus terminal Ready, will burst out of a more beautiful spark, to bring consumers unprecedented network experience. Commented.
4.5G scale business behind: with the entrepreneurial heart to promote
Today, Gbps has become a new mobile broadband speed standard, VoLTE commercial deployment has been the world to roll out, NB-IoT / eMTC / LTE-V and other Internet of things technology has also opened the industrialization process, 4.5G is rapidly changing People's way of life, and even change the whole human society, while the 4.5G can quickly in a few years from the concept of the proposed large-scale commercial process, as the initiator and the main promoter of Huawei is clearly not contributed.
'4.5G concept is now in the office we are sitting here to discuss out.' Should be pointed out that the generation of a dating technology generally have to go through ten years, as 2G to 3G with GPRS, 3G to 4G HSPA / HSPA + DC-HSPA +, the same need for such a bridge between 4G and 5G to help operators meet the growing demand from consumers, and explore and nurture new experiences for 5G, new business and new business models, 4.5G from This came into being.
In October 2014, Huawei first proposed 4.5G concept in the industry; February 24, 2015, published in London, UK 4.5G business blueprint and display 4.5G in the industry application, a comprehensive interpretation of 4.5G development prospects and direction; 2015 In October 2015, 3GPP at the 35th meeting of PCG officially identified the 4.5G new standard named LTE-Advanced Pro; in December 2015, following the hand of 4G commercial 6 years later, TeliaSonera and Huawei released the world's first in Oslo, Norway 4.5G commercial network, the current peak rate of 1Gbps network; 2016 World Mobile Communications Conference, the company together Norway TeliaSonera, Hong Kong HKT, South Korea LG Uplus, Poland P4, Kuwait VIVA and many other leading global operators jointly held 4.5G Strategic cooperation launch ceremony, a symbol of 4.5G global scale commercial launch.Currently, Huawei has been in the global operation of operators to deploy more than 100 4.5G commercial network.
But at the same time, 4.5G proposed to the business is not without twists and turns, have also encountered some skepticism in which, Huawei not only for the 4.5G standard to submit a large number of normative documents, and industry chain parties and even competitors to communicate In order to form a concerted effort, but also ripening the core technology and the entire end-to-end industrial chain, to promote the formation of the ecosystem.In addition, 4.5G to enter the vertical industry, open up new market space, in addition to operators and the telecommunications circle to contribute, Vertical industry players to participate in, Huawei held a variety of summit forums to provide cross-border exchange opportunities, and actively with international organizations, upstream and downstream industry chain, vertical industry cooperation, joint formation of industrial alliances.
'We are with the entrepreneurial heart to do 4.5G to promote this matter.' In the view of the people should be, Huawei in the wireless field to become a leader, is bound to assume more responsibility for the industry to pay more. For example, it is 4.5G in the corresponding networking that made a lot of efforts, and even specifically invested in a chip company (Neul) to achieve the rapid scale of the terminal size.
He also stressed that 4.5G / LTE Advanced Pro is not the last stop to 5G, will continue to evolve in 3GPP R15 / R16 and will coexist with the 5G - for at least five to ten years Play the main basis for carrying the main cash flow and the role of 'surplus in the moment to win the future'.
Full business very simple network: 5G to come ready
At the end of the year, the first phase of the 5G NR version of the agreement will be completed, the relevant technical testing, network verification has also been opened. Huawei believes that in order to 5G arrival When the initiative, the operator to do a good job in advance of the target network planning.
'The future of the network must be multi-frequency, multi-mode, multi-standard, three-dimensional network, how to manage such a complex network to meet the future of complex business, operators should pay special attention today.' , For 5G, operators should be in the user experience, network architecture and commercial birth to do a comprehensive preparation.
First of all, in terms of experience, Gbps is the standard of the 5G era, but through multi-antenna technology, multi-carrier aggregation, high-end modulation technology portfolio, today can achieve Gbps. Huawei recently released the unicorn 970 chip Mate 10 Pro, Can support 1.2Gbps peak rate; 4T4R is Giga experience the basic network, 8T8R is the best practice of high-capacity network, Massive MIMO can enhance single-station 40MHz bandwidth cell to 5Gbps capacity.
Architecture, the full cloud of the network structure, to support the smooth evolution of the hardware platform, will achieve the evolution of the 5G architecture Ready. In commercial nurturing, operators can use 4.5G full business ahead of the business, such as the Internet of Things , High-definition video, AR / VR, UAV, etc., but also need to strengthen the guidance and promotion in the industrial chain, such as 4 to receive antenna phones, Internet terminals and so on.
In the near future, China International Information and Communication Exhibition in 2017, Huawei released the concept of a full-service network, the so-called 'all business', that is, things, VoLTE, WTTx, car networking, sTTI low delay business All through the LTE network to carry; 'minimal' is reflected in the architecture, site, indoor, equipment, operation and maintenance and other aspects, such as the full range of the structure of the cloud, the site of the All in One antenna, indoor Lampsite and so on.
According to Huawei's wireless network LTE product line vice president Xu Xuebing previously introduced in the media interview, a full-service network will have five features - full spectrum to 4G, the release of network 20 + spectrum potential; , Faster deployment, lower cost; network capabilities more collaborative, enabling LTE better performance; operation and maintenance capabilities tend to AI, enabling future intelligent operation; solution 5G, enabling LTE future evolution.
