Although each big operation business forecasts name a person for a particular job of 5G commercial time,be in 2020, but the issuance that business of 5G mobile phone uses chip time can arrive ahead of schedule 2019, predict business of generation 5G uses mobile phone chip to will use 7nm technology at least, from the point of the news that has announced at present, connect high use in business of chip of 5G mobile phone. . . . . .
5G 3 big application, increase model mobile broadband will head hair
What be a delegate with quanta communication and 5G technology is new the arrival of revolution of round of science and technology, 5G will drive for nobody, the application such as content couplet net brings revolutionary experience change.
From the point of 5G application angle, at present main component becomes setting of 3 big application:
It is to increase above all model mobile broadband (Mobile EMBB) , give priority to with the mobile terminal such as the mobile phone namely, the 4G LTE from now to 5G gradually gradual progress. To mobile phone user, the rate that 5G brings and bandwidth promotion cannot be brought possibly overturn sexual user experiences promotion. On the global analyst plenary meeting that held a few days ago, china for spell president Xu Zhijun expresses, broad terminal unit user can not be aware of the ” of existence materiality difference between “5G and 4G technology possibly. Ben Stanton of analyst of Canalys of market research organization expresses his point of view at this point, the condition with true “ is, mobile industry is more to the foreground of 5G technology deflection at pessimism, but China be is first specification in the industry however the ” of large infrastructure supplier of fact of this be related.
Setting of the 2nd big application is millimeter wave technology, go in this domain United States most before leaning, at present main applied setting makes secure wireless receive facility (FWA) , this kind of setting is similar to fixed broadband, do not suit to be used in the shift application such as the mobile phone.
Setting of the 3rd big application is communication of high reliable small delay time (URLLC) and large-scale machine correspond (MMTC) , simple for the IoT that is 5G times corresponds. The NB-IoT that at present industry speaks of, EMTC, IoT that includes Cat M1/M0 to still be based on 4G LTE times corresponds. Future includes nobody to drive, the application such as AR/VR basically will use technology of this kind of 5G.
In Chinese market, because arrive 2020 5G commercial moment, all products basically are increasing centrally model mobile broadband, because the key of this article tells focusing,be in domain of chip of 5G mobile phone.
Why does Chinese operation business choose independent group net?
The frequency that becomes 5G besides new definition paragraph outside, still can have frequency of a lot of 4G to 2020 paragraph plough again, need is in on foundation of existing 4G radio frequency in the meantime supportive 5G-NR standard. The means New Radio of NR, at present the company of mobile phone chip of the mainstream, include to be connected high, China for, Intel will send and receive 5G-NR brand-newly the LTE chip of machine chip and 4G makes two chip. Predict more is based on to appear to the meeting after 2019 the generation of 5G-NR module.
Develop in 5G domain at present the bannerest basically is 4 countries: China, United States, Japan, Korea. Among them Chinese frequency paragraph basically be in 6GHz less than, have two frequency paragraph, one is the bandwidth of the 3.3 300MHz to 3.6GHz, another is 4.8 to 5GHz, 200MHz bandwidth. Spectrum resource of the United States arrives in 3.5G 3.7GHz, this also is why American operation business is before 2020 put the emphasis in millimeter wave, because do not have spectrum resource.
The 5G standard according to 3GPP alliance the first edition, cent establishs group network to not merely (Non-Stand Alone, NSA) and independent group net (Stand Alone, SA) two kinds of plan. Net of blame independence group serves as transfer plan, in order to promote heat area frequency wide for main goal, rely on 4G base station and job of 4G core net. Independent group net can realize the new character of all 5G, be helpful for developing the total capacity of 5G, it is the 5G goal plan with established industry. Simple for, NSA is 5G and 4G group net, control signal comes through 4G net, content is transmitted come through 5G net;SA is network of separate a piece of 5G, control signal and content are transmitted come through 5G net.
Expect according to exploding, there are two meetings to take SA course only in all operation business of the whole world at present, it is telecommunication of Chinese shift, China. Business of operation of other and all abroad, include Chinese UniCom, current program is NSA group net. SA and NSA group net have an advantage each. The advantage of NSA is core net, receive a net to be based on 4G-LTE, need to take data content level to do 5G only base station deploy, the angle from capital will be a lot of more economic. NSA also lets the whole world the 5G business of each big operation business shifts to an earlier date greatly with speed. Opposite for, the cloth net of SA needs to be thrown afresh entirely, include core network, accepting net, data catenary web is to be based on 5G-NR, investment is quite large.
Nevertheless the advantage of Chinese operation business depends on, carrying out 5G more is national strategy, because this need not pass,consider an issue more from cost angle. 5G has the function that network of a lot of LTE cannot realize, the network is for instance fictitious change section of management, network to wait, did not come additionally all NSA go to final gradual progress SA, from the devoted cost of integral system, the SA that one pace reachs the designated position may be final more economic.
What player is qualified enter battle of bureau 5G chip?
Connect high reveal the LTE Cat4 that carries from lowest to pursue to the Cat20 gradual progress of top end
Well-known, what 5G system design uses is LTE serves as a foundation, from LTE chip design ability can see ability of its 5G chip. LTE chip is the at present fiercest should be CAT20, it is CAT12 is mixed next 16, these rate can reach the capacity of 1Gbps above, achieve 1Gbps above rate only, just calculate qualified enter 5G war situation. The rate of be issued to lower levels of brave dragon X24 that knows high achieves 2Gbps, support Cat20, it is the business with global the at present rapiddest rate uses 4G base band.
Before this, gaotong released 5G new eat dishes without rice or wine (Qualcomm X50 of NR) modem series, predict to began to realize supportive 6GHz to be mixed below 2019 frequency of millimeter wave spectrum paragraph business of 5G mobile terminal is used.
Intel also announced series of XMM 8000 of chip of its 5G modem, exhibit in the MWC this year went up to also be revealed apply in the VR that makes the same score living broadcast of the video on prosperous Olympic Winter Games. Say with hearsay, malic general uses the XMM8060 5G base band of Intel in next generation Iphone.
SamSung also is developing technology of 5G base band to the utmost, although the analysis points out SamSung is developing group of RF antenna model and field of chip of 5G base band, especially millimeter wave domain lacks experience. On the CES 2018 nevertheless SamSung revealed Exynos 5G of its 5G base band, rate of highest supportable 5Gbps, predict the business at the beginning of 2019 is used, this and connect X50 business high to use time basic synchronism.
Although the resurgence microelectronics below resurgence banner is in 5G domain position is old, supportive Pre 5G also rolled out before this base station chip, did not release all the time nevertheless can measure truly produce chip of commercial 5G mobile phone.
Resurgence besides it is the telegraphic equipment provider with banner whole world, also be manufacturer of mobile phone terminal at the same time. And the MWC that holds before this is exhibited on, the machine of accurate 5G prototype that resurgence showed to use the 1.2Gbps that connects chip high to download speed. Be in China, china be and the main player that resurgence is 5G technology. Burn as the flames of war of Sino-US trade war nevertheless domain of science and technology, these two companies are differring of degree get negative effect. The embargo that the United States undertakes to resurgence makes mean resurgence to will not be used connect chip high to receive the business of 5G mobile phone that was about to come 2020 to use.
Compare with resurgence photograph, china for 2017 increase income completely 9 come from Wu of blame operation commerce into above, this expresses China to be depended on to operation commerce Wu apparently abate, and depend on to terminal income increase. China although avoid all the time,be with connect generation high to compete directly, but because be in the United States,the market cannot open a phase tardy, on the global analyst plenary meeting that Shenzhen held a few days ago, hua Weixuan cloth has regarded American market as no longer the one part of strategy of its whole world. Actually although do not have American market, china be operation business equipment already was the whole world the first, mobile phone shipment exceeds an apple also is not tickler.
Although be on the MWC this year, china to released Balong 5G 01 of first 5G chip. But China be the strategy since Hai Saiyi is straight is chip it is strategic weapon, use for him terminal brand only, at the same time China connect high to be being purchased all the time, the tripartite chip such as MTK. Such aux will be able to assure China bed smartphone business grows healthily. Together with the chip of 3 manufacturers mutual a competition, the competition ability that is helpful for kylin chip gets promotion ceaselessly. The author thinks, china those who be this decision-making it is to avoid on one hand direct with connect high wait for a supplier to produce direct competition, also be for the mature stability that oneself supplies chain on the other hand.
Although connect market sale high,PeterCarson of senior inspector general oppugns Hua Weixin when media is interviewed piece volume is too large, do not agree with the demand of mobile terminal. Nevertheless itself of Balong 5G 01 is not chip of a mobile phone, however a base band chip that is used in gateway product. Actually, china to also be in subsequently in be being publicized external, retaliate, think to begin 3GPP to just freeze the 5G standard of the first edition till December 2017, the ability that rolls out after this that is to say is true 5G standard chip. You can ask “ them, what standard is those who abide by? The physical layer standard of 5G is to go to what the end of the year just decides, cannot say myself is debugged can use, the standard did not call 5G then surely. ” Hua Weihai thinks of CTO Ai Wei to express. According to China for the description in official press release, balong 5G 01 is commercial of ” head money, according to the 5G chip ” of 3GPP standard.
According to introducing, the Hua Weiqi Lin that will release 2018 980 use the Balong765 of 4.5G base band that releases on this second MWC very likely, this chip supports LTE Cat19, FDD rate achieves 1.6Gbps, TD-LTE rate achieves 1.16Gbps. Predict to want to will roll out supportive mobile phone truly 2019 but business uses 5G chip.
A company that is worth to be carried is violet light exhibits vigor. Acute is exhibited to ever divulged its 5G plans before this, predict real business is used can be in 2021, arrive to be able to roll out standard and nonstandard R15 chip 2019, arrive to be able to roll out R16 chip 2020, solve the problem of research and development of parts of an apparatus of high frequency millimeter wave. We meet “ roll out the business of an embarking 5G chip that can illume to use a mobile phone in the MWC 2019. ”Jing Ming of king of the violet smooth CTO that exhibit vigor expresses, the generation business that postpones acute will serve as surveyor’s pole with Qualcomm X50 with 5G chip, peak value takes in and send out in large quantities frank meeting achieves 5Gb left and right sides, can join the function of Cat 15 at the same time.
The profit contribution of division of “5G couplet hair predicts to want 2020. Science and technology of ” couplet hair is announced in the message of 5G domain not as radical as friendly business, according to couplet hair science and technology senior vise general manager and technology grow (the description of CTO) Dr. Zhou Yujun, after particular trade may be delayed with time place, arrive 2020. According to divulging, MTK is already at present capable to offer the base band of 1Ghz above rate, it is the entrance ticket that took the battle that enters 5G, return the rate of the friendly business such as backward Yugaotong temporarily nevertheless. Zhou Yujun expresses, the opinion of MTK is strong when 5G enters mainstream application market arrive in front.
Zhou Yujun thinks, to increasing model for mobile broadband, no matter the mobile phone supports the frequency of radio frequency paragraph it is 4G or 5G, face a lot of challenges. You support “ impossibly merely 5G, still must fluctuate compatible 3G, 4G. ”Zhou Yujun thinks, 5G mobile phone will many more compositive frequency paragraph radio frequency, no matter be amplifier of filter, switch, power and integrated front module, can have generation of additional equipment of equipment parts of an apparatus. Because this 5G equipment can have a lot of distinction the semiconductor at 4G radio frequency yuan parts of an apparatus. The 5G base band that makes type more will need more cutting off quality, at the same time of RF complex degree also can support more combination, from cost, complex degree, in light of the angle such as power comsumption, 5G business should begin from 7nm at least with base band. In addition, the RF of 5G is sent and receive implement also will put a few functions base band domain.
The place on put together is narrated, although each big operation business forecasts name a person for a particular job of 5G commercial time,be in 2020, but the issuance that business of each big 5G mobile phone uses chip time can arrive ahead of schedule 2019, predict business of generation 5G uses mobile phone chip to will use 7nm technology at least. Include millet at present, China for, many mobile phone manufacturers such as OPPO, VIVO 5G mobile phone rolled out time to be in surely 2019. From the point of the news that has announced at present, connect high use in business of chip of 5G mobile phone foremost, and Intel and SamSung keep basically synchronous, after Hua Weiqi Lin tightens therewith, violet light exhibits acute and MTK to try best to catch up. Who can challenge the banner place that knows high? Believe to saw reason 2019.
