When it comes to 5G, the most exciting thing is that it is 100 times faster than 4G. Entering 2017, the industry's series of actions on 5G indicates that it is coming to us at "5G speed". The 5G era seems to be within reach.
Standard completion countdown in advance
To accelerate the launch of 5G, at this year's World Mobile Communications Conference (MWC), leading mobile operators and equipment vendors announced plans to propose an intermediate standard to deploy 5G new radio technology (5G NR) on a large scale in 2019. It was widely expected that 2020 will be one year earlier.
22 companies covering telecom operators, chip manufacturers and handset manufacturers including AT&T, NTT DoCoMo, SK Telecom, Vodafone, Ericsson, Qualcomm, BT, Telstra, Korea Telecom, Intel, LG Uplus, KDDI, LG Electronics, Telia The company, Swisscom (Swisscom), TIM, Etisalat Group, Huawei, Sprint, vivo, ZTE and Deutsche Telekom.
According to the current 3GPP Release 15 schedule, 5G new air interface deployment based on standards-compliant 5G NR infrastructure and terminals will not be realized until 2020. Unlike the above schedule, the new proposal proposes to complete the non-independent 5GNR specification document as an interim milestone to support the launch of large-scale trials and deployments in 2019. The non-independent 5G NR will leverage existing LTE wireless and evolved packet core networks as the backbone of mobility management and network coverage, while adding a new 5G wireless access carrier to support some 5G use cases by 2019. The new proposal and the mid-term milestone also reaffirmed and consolidated the timeline for completing all standards, including the independent 5G NR in Release 15.
At the same time, the companies supporting the proposal are further committed to using forward compatibility as a key design principle in the standardization of the first version of the 5G NR. This will support the introduction of new features and features in subsequent releases in the band, which is critical to supporting the 5G vision of industries and use cases that are currently undetermined and enabling the Internet of Everything.
Jinhyo Park, senior vice president of SK Telecom and head of the network R&D center, broke the importance of this move: "The demand for 5G commercial is booming, so it is especially important to complete the globally recognized 5G standard in time. 3GPP's 5G NR is global 5G standard, we are working together with partners to continuously accelerate the development of 3GPP new air interface standards."
The telecom operators who have their own clear timetable for 5G deployment are even more eager to wait. NTT DoCoMo's executive vice president and chief technology officer, Osumi Masahiro said: "DoCoMo plans to deploy a non-independent 5G NR commercial deployment by 2020. Accelerating the standardization process will facilitate the early deployment of standards-based 5G NR." Director of Telstra Networks Group Manager Mike Wright also said: "Telstra is committed to the benefits of industry standardization. Telstra will conduct extensive 5G pre-tests in 2018. On this basis, the mid-term milestone of achieving this 5G NR will help 2019. 5G commercialization will be realized as soon as possible.†KIDDI board member and technical department head Uchida said: “For fast commercial 5G, global coordination (including spectrum bands and specifications) is more important than previous generations. KDDI aims to be 2020 Start the 5G service, which requires the completion of the new air interface specification as soon as possible."
YongGyoo Lee, senior vice president of network strategy at Korea Telecom, said: "We are encouraged by the growing voice in the telecommunications industry to accelerate the process of the new air interface specification. Korea Telecom believes that non-independent and independent models are standards-compliant. Equally important. However, we believe that the introduction of 5G networks as early as possible and supplemented by LTE networks that have been widely covered is a very reasonable approach for operators, especially considering the return on investment. It also confirms the tendency to consider non-independent modes when considering priorities. We believe that 5G will not only be able to achieve higher data rates, but 5G will completely change the way we provide communication services to customers, and ultimately operate at low cost for telecom operations. The company has added a variety of revenue channels. I believe that the entire industry will benefit from the rapid commercialization of 5G, which is to be achieved through the 3GPP accelerated 5G new air interface specification process."
Operators speed up running
According to the 5G schedule released by 3GPP, the first phase of the 5G standard development work, that is, the first version of the 5G standard, 3GPP Release 15 is planned to be completed in September 2018, and the commercial estimate is expected to be around 2019. The second phase, the second version of the 5G standard, 3GPP Release 16 is planned to be completed in March 2020. It takes another one or two years from the completion of the technical standard to the commercial landing, which is estimated to be around 2022. But in fact, the pace at which 5G is coming to us is much faster than this.
It was only two months before entering 2017, and the news about 5G is endless.
On February 9, 3GPP International Communication Standards Organization officially announced that "5G" will become the official name of the next generation mobile network connection technology, and at the same time release the official logo of 5G network. With the finalization of the official logo, the "image" of 5G is coming. The clearer it is.
Recently, Deutsche Telekom, Ericsson and SK Telecom jointly announced the completion of the world's first intercontinental 5G network test, which is expected to clear the roadblocks for the global roaming function of 5G technology that has not been standardized.
According to industry data from the global 5G test status released by network test company Viavi Solutions, 25 mobile operators around the world have conducted laboratory tests on 5G. Among them, 12 said they have entered the field test phase, and another 4 operators announced the 5G test plan.
In the 5G test, five operators have reached data rates of 35 Gbps or more. Among them, Etihad Telecom (Etisalat) achieved a data transmission rate of 36 Gbps, Qatar Telecom (Ooredoo) achieved a data transmission rate of 35.46 Gbps, Australia's Optus and Singapore's first pass and Star and respectively achieved a data transmission rate of 35 Gbps. All other operators conducting 5G testing have released data transmission rates of at least 2 Gbps.
In addition, Viavi's data shows that the spectrum of the operators tested is large, from sub-3GHz to 86GHz, but the most commonly used test band is 28GHz, which is used by 8 operators; followed by 15GHz, which is used by 7 operators.
Early adopter 5G is close at hand
As the pace of operators accelerates, consumers are “early adopting†5G. Verizon, which is developing its own 5G wireless technology, announced on February 22 that it will select some users to provide 5G pre-commercial services in 11 cities in the US in the first half of this year. By then, the pre-commercial network will be covered by "hundreds of base stations covering thousands of user scenarios."
The 11 cities include Ann Arbor, Atlanta, Bernersville, Brockton, Dallas, Denver, Houston, Miami, Sacramento, Seattle and Washington, DC.
At last year's Mobile World Congress in Spain, Verizon announced that it would conduct a 5G pilot deployment in the United States. Verizon has been conducting field testing for approximately one year based on the 5G radio specification developed by the technology partner 5GTF, and this announcement means that these services will be officially open to consumers.
Not long ago, Verizon's biggest competitor, AT&T, announced that it would provide experimental operation of 5G networks in the two cities of Austin and Polis. It is said that the initial stage will provide 400Mbps mobile Internet speed, which can be upgraded to 1Gbps. A few days ago, AT&T and Nokia just completed the first fixed wireless 5G test through AT&T's Internet streaming service DirecTV Now in the 39GHz band.
With the arrival of South Korea’s Winter Olympics in February next year and the arrival of Russia’s 2018 World Cup next summer, the world’s first official 5G commercial service is expected to be launched by the end of this year or early 2018. Telia, who led the world in the 4G era, also said that the goal is to adopt mobile 5G in the Nordic capital city in 2018.
