Telefone ya 5G ifite imbaraga zingahe?

Hamwe no kubaka umuyoboro wa 5G, igiciro cya sitasiyo ya 5G ni kinini cyane, cyane ko ikibazo cyo gukoresha ingufu nini cyamenyekanye cyane.

Kubijyanye na China Mobile, kugirango ishyigikire umuvuduko mwinshi, module yayo ya 2.6GHz ya radiyo isaba imiyoboro 64 hamwe na watt 320.

Naho terefone zigendanwa 5G zishyikirana na sitasiyo fatizo, kubera ko zikorana cyane numubiri wumuntu, umurongo wanyuma w "imishwarara yangiza" ugomba kurindwa byimazeyo, bityo imbaraga zo kohereza zikaba nke cyane.

Porotokole igabanya ingufu za terefone zigendanwa za 4G kugeza kuri 23dBm (0.2w).Nubwo izo mbaraga atari nini cyane, inshuro ya 4G nyamukuru (FDD 1800MHz) ni mike, kandi igihombo cyohereza ni gito.Ntabwo ari ikibazo kuyikoresha.

Ariko ibintu 5G biragoye.

Mbere ya byose, umurongo wingenzi wa 5G ni 3.5GHz, inshuro nyinshi, gutakaza inzira nini yo gukwirakwiza, ubushobozi buke bwo kwinjira, ubushobozi buke bwa terefone igendanwa, nimbaraga nke zohereza;kubwibyo, kuzamuka biroroshye guhinduka sisitemu.

Icya kabiri, 5G ishingiye kuburyo bwa TDD, kandi kuzamura no kumanikwa byoherejwe mugihe cyo kugabana.Muri rusange, kugirango tumenye ubushobozi bwo kugabanuka, kugenerwa umwanya wo kuzamuka ni bike, hafi 30%.Muyandi magambo, terefone ya 5G muri TDD ifite 30% gusa yigihe cyo kohereza amakuru, ibyo bikagabanya imbaraga zo kohereza.

Byongeye kandi, uburyo bwo kohereza 5G buroroshye, kandi imiyoboro iragoye.

Muburyo bwa NSA, 5G na 4G byohereza amakuru icyarimwe hejuru yuburyo bubiri, mubisanzwe 5G muburyo bwa TDD na 4G muburyo bwa FDD.Muri ubu buryo, terefone igendanwa ikwiye kohereza imbaraga?

5G1

 

Muburyo bwa SA, 5G irashobora gukoresha TDD cyangwa FDD itwara imwe.Kandi guteranya abatwara ubu buryo bubiri.Kimwe nikibazo cyuburyo bwa NSA, terefone igendanwa igomba kohereza icyarimwe icyarimwe kumirongo ibiri itandukanye, na TDD na FDD muburyo bubiri;imbaraga zingana iki?

 

5G2

 

Byongeye kandi, terefone igendanwa ikwiye kohereza ingufu zingahe niba abatwara TDD bombi ba 5G bakusanyije?

3GPP yasobanuye urwego rwimbaraga nyinshi kuri terminal.

Kuri Sub 6G, imbaraga za 3 ni 23dBm;urwego rwimbaraga 2 ni 26dBm, naho kurwego rwimbaraga 1, imbaraga za theoretical nini, kandi kuri ubu nta bisobanuro.

Bitewe numurongo mwinshi hamwe nibiranga itandukanyirizo bitandukanye na Sub 6G, ibintu byo gusaba birasuzumwa cyane mugukosora uburyo bwo gukoresha cyangwa gukoresha terefone zitagendanwa.

Porotokole isobanura imbaraga enye za milimetero-umuraba, kandi imirasire iragutse.

Kugeza ubu, 5G ikoreshwa ryubucuruzi rishingiye cyane cyane kuri terefone igendanwa serivisi ya eMBB muri band ya Sub 6G.Ibikurikira bizibanda cyane cyane kuri ibi bintu, byibanda kumurongo wingenzi wa 5G yumurongo (nka FDD n1, N3, N8, TDD n41, n77, N78, nibindi).Igabanyijemo ubwoko butandatu bwo gusobanura:

  1. 5G FDD (SA uburyo): imbaraga ntarengwa zo kohereza ni urwego 3, ni 23dBm;
  2. 5G TDD (SA uburyo): imbaraga nyinshi zohereza ni urwego 2, ni 26dBm;
  3. 5G FDD + 5G TDD CA (SA uburyo): imbaraga nyinshi zohereza ni urwego 3, ni 23dBm;
  4. 5G TDD + 5G TDD CA (uburyo bwa SA): imbaraga nyinshi zohereza ni urwego 3, ni 23dBm;
  5. 4G FDD + 5G TDD DC (uburyo bwa NSA): imbaraga nyinshi zohereza ni urwego 3, ni 23dBm;
  6. 4G TDD + 5G TDD DC (uburyo bwa NSA);Imbaraga ntarengwa zo kohereza zasobanuwe na R15 ni urwego 3, ni 23dBm;na verisiyo ya R16 ishyigikira ntarengwa yohereza ingufu urwego 2, ni 26dBm

 

Duhereye ku bwoko butandatu bwavuzwe haruguru, dushobora kubona ibintu bikurikira:

Mugihe cyose terefone igendanwa ikora muburyo bwa FDD, imbaraga nyinshi zohereza ni 23dBm gusa, mugihe muburyo bwa TDD, cyangwa imiyoboro itigenga, 4G na 5G byombi ni uburyo bwa TDD, imbaraga nyinshi zohereza zishobora kuruhuka kuri 26dBm.

None, kuki protocole yita cyane kuri TDD?

Nkuko twese tubizi, inganda zitumanaho zagiye zigira ibitekerezo bitandukanye niba imirasire ya electronique.Nubwo bimeze bityo, kubwumutekano, imbaraga zo kohereza terefone zigendanwa zigomba kuba nke.

5G3

Kugeza ubu, ibihugu n’amashyirahamwe byashyizeho imirasire y’umuriro wa elegitoroniki yerekana imbaraga z’ubuzima, bigabanya imirasire ya terefone igendanwa.Igihe cyose terefone igendanwa yujuje aya mahame, irashobora gufatwa nkumutekano.

 

Ibipimo byubuzima byose byerekana icyerekezo kimwe: SAR, ikoreshwa cyane mugupima ingaruka ziterwa nimirasire yumurima hafi ya terefone igendanwa nibindi bikoresho byitumanaho byikurura.

SAR ni igipimo cyihariye cya Absorption.Irasobanurwa nko gupima igipimo imbaraga zinjizwa muri misa imwe numubiri wumuntu iyo ihuye numurongo wa radiyo (RF) amashanyarazi.Irashobora kandi kwerekeza ku kwinjiza ubundi buryo bwingufu ukoresheje tissue, harimo na ultrasound.Irasobanurwa nkimbaraga zinjizwa kuri misa ya tissue kandi ifite watts ibice kuri kilo (W / kg).

 

5G4

 

Igipimo cy’igihugu cy’Ubushinwa gishingiye ku bipimo by’Uburayi kandi giteganya: “impuzandengo ya SAR ya 10g y’ibinyabuzima iyo ari yo yose mu minota itandatu ntishobora kurenga 2.0W / Kg.

Nukuvuga, kandi ibipimo ngenderwaho bisuzuma impuzandengo yimirasire yumuriro wa electronique ikorwa na terefone igendanwa mugihe gito.Yemerera gato hejuru mumbaraga zigihe gito, mugihe cyose impuzandengo igiciro kitarenze igipimo.

Niba imbaraga nyinshi zohereza imbaraga ari 23dBm muburyo bwa TDD na FDD, terefone igendanwa muburyo bwa FDD ikomeza kohereza ingufu.Ibinyuranye, terefone igendanwa muburyo bwa TDD ifite 30% gusa yohereza ingufu, bityo ingufu zose zohereza imyuka ya TDD ni 5dB munsi ya FDD.

Kubwibyo, kugirango yishyure uburyo bwo kohereza bwa TDD na 3dB, biri muburyo bwa SAR kugirango uhindure itandukaniro riri hagati ya TDD na FDD, kandi rishobora kugera kuri 23dBm mugereranije.
