Iicamps ze-5G zilusizi? Abavelisi aba-5 bonwabele okwethutyana ikhekhe elikhulu le-5G

Ngokwengxelo yothungelwano lwemali yomsebenzisi, abangena ngaphakathi kumzi mveliso baveze ukuba emva koluhlu lwezinye iifowuni ezi-5G, abavelisi bafumanise ukuba abavelisi beeplanethi be-5G bahlupheke kakhulu, ngaba zintlanu kuphela, iinkampani zeefowuni eziphathwayo zinokhetho oluncinci kakhulu lwe-5G chips.

Iinkampani ezinokukhulisa i-5G chips yiHuawei HiSilicon, Qualcomm, Samsung, MediaTek, kunye neZiguang.

Ekuqaleni kwalonyaka, uHuawei wakhupha ngokusemthethweni i-chip ye-multimode terminal chip, iBalong 5000, emhlabeni. I-chip yamkela inkqubo ye-7nm, umgangatho wokukhuphela ukuya kuthi ga kwi-4,6Gbps kwinethiwekhi ye-5G Sub-6GHz band, izinga lokukhuphela le-6.5Gbps kumatshini we-mmWave (millimeter wave), ishishini lixhasa iNR TDD kunye ne-FDD Imo ye-SA ne-NSA 5G yenethiwekhi. Ngokwaziswa kukaHuawei, iBaron 5000 yi-5G terminal baseband chip kunye nokudityaniswa okuphezulu kunye nokusebenza okuphezulu kwimveliso. Ayisiyo kuphela i-chip yokuqala ye-single-chip multimode 5G baseband, kodwa ikwaxhasa izisombululo ze-2G, 3G, 4G, 5G single-chip, ngokusebenzisa amandla asezantsi kunye nokusebenza okungcono.

I-Qualcomm ikhuphe i-chip yesibini ye-5G baseband Snapdragon X55 kulo nyaka, esekwe kwitekhnoloji yenkqubo ye-7nm. I-chip enye ixhasa i-2G, 3G, 4G, i-multimode ye-5G, kwaye ixhasa amaza amamilimitha kwaye ingezantsi kwe-6GHz frequency band, exhasa imigangatho ye-TDD kunye ne-FDD. Xhasa indlela yenethiwekhi ezimeleyo, engazimeleyo. Kwimo ye-5G, i-Opteron X55 inokuphumeza isantya sokukhuphela ukuya kuthi ga kwi-7Gbps kwaye ilayishe isantya esinyukayo ukuya kwi-3Gbps. Ikwaxhasa ikati ye-22 LTE yesantya sokukhuphela ukuya kufikelela kwi-2,5 Gbps.

I-Samsung ikhuphe i-chip yayo yokuqala ye-5G yesiseko se-Exynos Modem 5100 kunyaka ophelileyo. Ngokweendlela ezichaziweyo, i-Exynos Modem 5100 chip yakhiwe ngetekhnoloji ye-10nm LPP, ixhasa i-Sub 6GHz frequency ephantsi (esetyenziswe e China) kunye mmWave (wave millimeter) frequency ephezulu, backward ehambelana ne 2G / 3G / 4G, kubandakanya kodwa kungaphelelanga kwi GSM , I-CDMA, i-WCDMA, i-TD-SCDMA, i-HSPA, i-4G LTE, njl njl. Imodeli ye-Exynos 5100 inokufezekisa izinga lokukhuphela ukuya kuthi ga kwi-2 Gbps kwi-Sub 6 GHz, i-6 Gbps yokukhuphela kwinqanaba le-millimeter wave band, kunye ne-4 Gbps isantya ukuya kwi-1.6 Gbps.

I-MediaTek ikhuphe iqonga layo le-5G ngoMeyi kulo nyaka. Inkqubo yemultimode 5G eyodwa-chip (SoC) yenziwa kwinkqubo ye-7nm nge-modem eyakhelweyo ye-5G Helio M70. Eli qonga le-multimode 5G yefowuni ilungele i-5G ezimeleyo nezingazimeliyo (SA). / NSA) Uyilo lwenethiwekhi ye-Sub-6GHz ye-frequency band, inkxaso ehambelana ukusuka kwi-2G ukuya kwi-4G izizukulwana zetekhnoloji yoqhagamshelo. Inesantya sokukhuphela i-4.7 Gbps kunye nesantya sokulayisha esiyi-2,5 Gbps.

UZiguang Zhanrui ukhuphe i-chip ye-5G baseband I-510 kwi-MWC 2019 ebibanjwe ngoFebruwari kulo nyaka. Yamkela iteknoloji yenkqubo ye-12nm ye-TSMC, ixhasa inani leetekhnoloji eziphambili ze-5G, inokufikelela kwi-2G / 3G / 4G / 5G iindlela zonxibelelwano ezininzi, ihambelana ne-3GPP R15 imigangatho emiselweyo, ixhasa i-Sub-6GHz band frequency band kunye ne-100MHz bandwidth, ukudibanisa ukusebenza okuphezulu, amandla aphantsi 5G baseband chip. Ukongeza, i-Ivy 510 inokuthi ixhase zombini iindlela zonxibelelwano zase-SA (zonxibelelwano ezizimeleyo) kunye ne-NSA (non-ezimeleyo zonxibelelwano) ngeendlela zokufikelela ngokupheleleyo kwiimfuno zonxibelelwano kunye neemfuno zenethiwekhi kwinqanaba lesigaba se-5G. Umgangatho wethanga lokuthoba wezantsi ngu-1.5 Gbps kwi-NSA 2.6G band.

Kuba i-chip ye-5G baseband kufuneka ihambelane kunye neenethiwekhi ze-2G / 3G / 4G ngaxeshanye, iindlela kunye neebhendi ezihamba rhoqo ezifuna ukuxhaswa zikhuliswe kakhulu. Ukukhuseleka kwe-Everbright kwakhokelela kwingxelo yophando ukuba ifowuni yangoku ye-4G kufuneka ixhase imodeli yemodeli ezi-6, kwaye ziya kufikelela kwiimodyuli ezisi-7 kwixesha le-5G, ubunzima bokwakhiwa kwe-chip buya kuphuculwa kakhulu. Abavelisi be-chip, badinga uphando olomeleleyo lobugcisa kunye namandla ophuhliso. Phakathi kwabo, i-Intel, enethemba malunga nomzi mveliso, ayikwazanga ukuhambisa iimpendulo ezanelisayo kwaye nje ithengise ishishini lesiseko kwi-Apple.

Ezi mfuno ziphezulu kunye nobunzima bokuyila zikhokelele ekuveliseni abambalwa beeplanethi ze-5G ze-chip, kodwa nokuba kukho imeko ye-oligopoly, ukhuphiswano lusavutha. Xa ujongene ne-5G, le khekhe ayizimisele kutya kancinane. Ngaphezu koko, kusekho uninzi lwabenzi be-chip abakhawulezayo kule echelon, kwaye amava aphezulu kunye nokwehla aya kulindeleka.
