Indima ephambili ye-C-band kwiinethiwekhi ze-5G kunye nokubaluleka kwayo

I-C-band, i-radio spectrum ene-frequency range phakathi kwe-3.4 GHz kunye ne-4.2 GHz, idlala indima ebalulekileyo kwiinethiwekhi ze-5G. Iimpawu zayo ezizodwa zenza kube ngundoqo ekufezekiseni i-high-speed-speed, low-latency, kunye ne-wide-coverage yeenkonzo ze-5G.

1. Ukhuseleko olulungeleleneyo kunye nesantya sothumelo

I-C-band iyinxalenye ye-middle-band spectrum, enokubonelela ngebhalansi efanelekileyo phakathi kokugubungela kunye nesantya sokuhanjiswa kwedatha. Xa kuthelekiswa ne-low-band, i-C-band inokubonelela ngemilinganiselo ephezulu yokuhanjiswa kwedatha; kwaye xa kuthelekiswa namabhendi aphezulu-frequency (njengamaza e-millimeter), i-C-band ine-coverage ebanzi. Le bhalansi yenza i-C-band ifaneleke kakhulu ukuhambisa amanethiwekhi e-5G kwiindawo ezisezidolophini nasezidolophini, ukuqinisekisa ukuba abasebenzisi bafumana uxhulumaniso olukhawulezayo ngelixa benciphisa inani lezikhululo ezisisiseko ezisetyenzisiweyo.

2. Ubuninzi bemithombo ye-spectrum

I-C-band ibonelela nge-bandwidth ye-spectrum ebanzi ukuxhasa umthamo omkhulu wedatha. Umzekelo, i-Federal Communications Commission (FCC) yase-United States yabele i-280 MHz ye-mid-band spectrum ye-5G kwi-C-band kwaye yathengiswa ekupheleni kuka-2020. izixhobo kule fandesi, ukubonelela ngesiseko esiluqilima iinkonzo zabo 5G.

3. Ukuxhasa iteknoloji ye-5G ephezulu

Iimpawu ze-frequency ze-C-band ziyenza ikwazi ukuxhasa ngokufanelekileyo itekhnoloji ephambili kuthungelwano lwe-5G, njenge-MIMO enkulu (i-multiple-input-multiple-output) kunye ne-beamforming. Ezi teknoloji zinokuphucula ukusebenza kakuhle kwe-spectrum, ukwandisa umthamo wenethiwekhi, kunye nokuphucula amava omsebenzisi. Ukongeza, inzuzo ye-bandwidth ye-C-band yenza ukuba ihlangabezane neemfuno ezikhawulezayo kunye ne-low-latency yezicelo ze-5G ezizayo, ezifana ne-augmented reality (AR), i-virtual reality (VR), kunye ne-Intanethi yezinto (IoT). ).

4. Usetyenziso olubanzi kwihlabathi jikelele

Amazwe amaninzi kunye nemimandla isebenzise i-C-band njengeyona bhendi yefrikhwensi yothungelwano lwe-5G. Ngokomzekelo, amazwe amaninzi eYurophu nase-Asia asebenzisa i-n78 band (3.3 ukuya kwi-3.8 GHz), ngelixa i-United States isebenzisa i-n77 band (3.3 ukuya kwi-4.2 GHz). Oku kuhambelana kwehlabathi jikelele kunceda ukwenza i-ecosystem ye-5G edibeneyo, ukukhuthaza ukuhambelana kwezixhobo kunye nobuchwepheshe, kunye nokukhawulezisa ukuthandwa kunye nokusetyenziswa kwe-5G.

5. Ukukhuthaza ukuthunyelwa kwezorhwebo kwe-5G

Ukucwangciswa okucacileyo kunye nokwabiwa kwe-C-band spectrum kuye kwakhawulezisa ukuthengiswa kwee-intanethi ze-5G. E-China, i-Ofisi yoMphathiswa wezoShishino kunye neTekhnoloji yoLwazi ichaze ngokucacileyo i-3300-3400 MHz (ukusetyenziswa kwangaphakathi kwimigaqo), i-3400-3600 MHz kunye ne-4800-5000 MHz iibhendi njengeebhendi zokusebenza zeenkqubo ze-5G. Olu cwangciso lunika isikhokelo esicacileyo sophando kunye nophuhliso kunye nokuthengiswa kwezixhobo zenkqubo, ii-chips, ii-terminals kunye nezixhobo zokuvavanya, kunye nokukhuthaza ukuthengiswa kwe-5G.

Isishwankathelo, i-C-band idlala indima ebalulekileyo kwiinethiwekhi ze-5G. Iinzuzo zayo kwi-coverage, isantya sothumelo, izibonelelo ze-spectrum kunye nenkxaso yobugcisa yenza kube sisiseko esibalulekileyo sokuqonda umbono we-5G. Njengoko ukuhanjiswa kwe-5G yehlabathi kuhambela phambili, indima ye-C-band iya kuba yinto ebaluleke kakhulu, izisa abasebenzisi amava onxibelelwano olungcono.
