Recently, one piece is concerned China for Mate 20 " double card double " PPT check scheme is divulged on the net, explode expect the graph shows, china support double card not only for Mate 20 double wait for, and can accomplish double card double VoLTE double. As it is said, also have only at present China to can be accomplished, precede inside course of study. Because of double card double VoLTE double a much frequency that should hold customer deputy check concurrently not only paragraph support, solve even advocate the problem of the interference that be the same as frequency between deputy card. This nature profit from China accumulate for what the mobile phone comes in communication technology respect for years.
Be in early times of the 2G more than 10 years ago, 3G, the strong desire that departs to life date, work number to cater to an user, manufacturers of many homebred mobile phone begin to join two SIM to block groove in a mobile phone, one machine double card went to the lavatory greatly the life work requirement of the user, from now on double card double wait for a mobile phone to be in home gradually arisen, form popular trend.
Arrived 4G times, double card double waiting for is to become a mark of homebred mobile phone to match more, the mobile phone that does not support this configuration instead is rare. But also have an exception, be regarded as to initiate the IPhone of smartphone beginning, old since hold to odd SIM card all the time however " feelings " , pink of fruit of home of at one's convenience looking forward to with eager expectancy, apple still apathetic.
Go a few years, concerned IPhone should add double card double the rumor that treat is incessant Yu Er, the hope of fruit pink comes to nothing however. But the ceaseless innovation that faces homebred mobile phone and intense competition, malic most propbably also felt pressure, this year the 2nd quarter by China to surmount, retreat house whole world the 3rd.
As direct competitor of the apple, china it is for terminal CEO Yu Chengdong after malic news briefing send small gain to say for a short while: "Firm, 16 days of London see our October! " apparent, the Mate 20 set that is about to issue is right on each function configuration mark IPhone, yu Chengdong already have a well-thought-out plan.
For " please " Chinese consumer, the new generation IPhone that before dawn released on September 13 is like eventually wished to add double card double wait for a function, make news briefing number not much " explode dot " one of. This, the apple is aimed at Chinese user first special offerred two SIM substance to block groove (ESIM of short duration not admittance) , but in 3 new IPhone, only IPhone XS Max and IPhone XR support double card double wait for, IPhone XS still is only card configuration, will look from this, of the apple " open " not complete.
In news briefing spot, the apple offerred Western style first make a way -- DSDS(Dual Sim Dual Standby) , actually the interpreter comes over is pair of card double wait for, without what profound " black science and technology " , the double card that offerred lowermost level only double wait for a function, even " double VoLTE " still also cannot support, and still be sheet is connected.
That is to say, of new IPhone have one only Zhang Zhuka can use 4G signal, card of another piece of SIM can realize 2G to speech communicates and receive the service such as the short message only, be in numerous double card in this one configuration, can be only " beggar edition " .
The double card sheet that compares new IPhone is connected, double card double VoLTE double can realize a piece of card to call, it is OK also that another piece of card still can be hit receive listen.
Cite a case, use the mobile phone that double card sheet connects, when driving, use navigation of a piece of net blocking couplet, if another piece of card calls a phone to receive,listen right now, navigation can be interrupted. Again for instance, you are playing " Wang Zherong boasts " , another telephone incoming message is entered receive listen, game can drop a line directly, pair of mobile phones that connect won't appear similar problem.
In addition, china still support double VoLTE for Mate 20, additional no matter advocate card or deputy card are in when calling, additionally one piece of card can get online at the same time (need two pieces of card to open VoLTE function) , each other noninterference.
Well-known, china for with communication technology build up, the deepest communication technology in having mobile phone firm through development of a few years is accumulated and actual strength of research and development, be in so double card double wait for this thing to go up, china the banner superiority that faces new IPhone nature to have clearly for Mate 20, yu Chengdong is really qualified also say " firm " .
In fact, china had become rod of industry internal standard to be on experience of field of mobile phone communication, match with mark of Mate 10 series " tall swage type " for exemple, below the requirement that exceeds 300 kilometers in speed per hour, the user setting that can fall to drop a line easily in the light of setting of high speed shift undertakes deepness is optimized, decreased to reduce a word to lead considerably at the same time, let an user still can enjoy stable and fast network join below the setting with mobile high speed.
And had kylin of 980 add hold and first backs LTE Cat.21 base band inside course of study, china can achieve the rate of 1.4Gbps be issued to lower levels with top industry for Mate 20 theory, support 256QAM, make the 4.5G product with the at present rapiddest rate. At the same time form a complete set uses the Hi1103 of wireless chip of mobile phone Wi-Fi with the fastest whole world, take the lead in supporting 160M bandwidth, theoretical peak value downloads rate to be able to amount to 1.7Gbps, it is 1.7 times of level of industry the corresponding period. Hi1103 still supports essence of GPS of L1+L5 Shuang Pin to locate definitely, l5 frequency paragraph fixed position precision promotes 10 times, area of road and other places is worn complex urban gorge, high in landform also but essence of life allows navigation.
Believe, besides, had claimed " firm " China for, what can bring more expect to be less than on series of new admiral Mate 20 is surprizing, on October 16 our wait and see what happens.
