Udindo waukulu wa gulu la C mu maukonde a 5G ndi kufunika kwake

C-band, yomwe ndi wailesi yokhala ndi ma frequency pakati pa 3.4 GHz ndi 4.2 GHz, imagwira ntchito yofunika kwambiri pa ma network a 5G. Makhalidwe ake apadera amapangitsa kuti ikhale yofunika kwambiri pakupeza ntchito za 5G zothamanga kwambiri, zochedwa pang'ono, komanso zofalikira kwambiri.

1. Kufalikira koyenera komanso liwiro lotumizira

Gulu la C-band ndi la gulu lapakati, lomwe lingapereke mgwirizano woyenera pakati pa kufalikira ndi liwiro lotumizira deta. Poyerekeza ndi gulu lochepa, gulu la C-band lingapereke kuchuluka kwa kutumizira deta; ndipo poyerekeza ndi magulu amphamvu kwambiri (monga mafunde a millimeter), gulu la C-band lili ndi kufalikira kwakukulu. Kuchuluka kumeneku kumapangitsa gulu la C-band kukhala loyenera kwambiri kugwiritsa ntchito maukonde a 5G m'mizinda ndi m'madera akumidzi, kuonetsetsa kuti ogwiritsa ntchito akupeza kulumikizana kwachangu pomwe akuchepetsa kuchuluka kwa malo oyambira omwe atumizidwa.

2. Zinthu zambiri zopezeka m'ma spectrum osiyanasiyana

Gulu la C limapereka bandwidth yayikulu yothandizira kuchuluka kwa deta. Mwachitsanzo, bungwe la Federal Communications Commission (FCC) la ku United States linapereka ma 280 MHz a mid-band spectrum a 5G mu gulu la C ndipo linagulitsa kumapeto kwa chaka cha 2020. Ogwira ntchito monga Verizon ndi AT&T adapeza zinthu zambiri za spectrum mu malonda awa, zomwe zinapereka maziko olimba a ntchito zawo za 5G.

3. Thandizani ukadaulo wapamwamba wa 5G

Makhalidwe a pafupipafupi a C-band amaithandiza kuthandizira bwino ukadaulo wofunikira mu ma network a 5G, monga massive MIMO (multiple-input multiple-output) ndi beamforming. Maukadaulo awa amatha kusintha magwiridwe antchito a spectrum, kukulitsa mphamvu ya netiweki, ndikuwonjezera zomwe ogwiritsa ntchito akukumana nazo. Kuphatikiza apo, ubwino wa bandwidth wa C-band umaithandiza kukwaniritsa zofunikira za liwiro lapamwamba komanso lotsika la ntchito zamtsogolo za 5G, monga augmented reality (AR), virtual reality (VR), ndi Internet of Things (IoT).

4. Kugwiritsa ntchito padziko lonse lapansi

Mayiko ndi madera ambiri agwiritsa ntchito C-band ngati bande lalikulu la ma frequency pa ma network a 5G. Mwachitsanzo, mayiko ambiri ku Europe ndi Asia amagwiritsa ntchito n78 bande (3.3 mpaka 3.8 GHz), pomwe United States imagwiritsa ntchito n77 bande (3.3 mpaka 4.2 GHz). Kugwirizana kumeneku padziko lonse lapansi kumathandiza kupanga chilengedwe chogwirizana cha 5G, kulimbikitsa kugwirizana kwa zida ndi ukadaulo, ndikufulumizitsa kufalikira ndi kugwiritsidwa ntchito kwa 5G.

5. Limbikitsani kutumizidwa kwa 5G m'malonda

Kukonzekera bwino ndi kugawa kwa C-band spectrum kwathandizira kufalikira kwa maukonde a 5G m'malonda. Ku China, Unduna wa Zamalonda ndi Ukadaulo wa Chidziwitso wasankha momveka bwino ma band a 3300-3400 MHz (ogwiritsidwa ntchito m'nyumba), 3400-3600 MHz ndi 4800-5000 MHz ngati ma band ogwiritsira ntchito machitidwe a 5G. Kukonzekera kumeneku kumapereka malangizo omveka bwino pakufufuza ndi kupanga ndi kugulitsa zida zamakompyuta, ma chips, ma terminal ndi zida zoyesera, ndikulimbikitsa kugulitsa kwa 5G.

Mwachidule, gulu la C-band limagwira ntchito yofunika kwambiri pa maukonde a 5G. Ubwino wake pakufalikira, liwiro la kutumiza mauthenga, zida zowunikira komanso chithandizo chaukadaulo zimapangitsa kuti likhale maziko ofunikira pakukwaniritsa masomphenya a 5G. Pamene kufalikira kwa 5G padziko lonse lapansi kukupita patsogolo, ntchito ya gulu la C idzakhala yofunika kwambiri, zomwe zimabweretsa chidziwitso chabwino kwa ogwiritsa ntchito.
