C-band, ma radio sipekitiramu okhala ndi ma frequency osiyanasiyana pakati pa 3.4 GHz ndi 4.2 GHz, imagwira ntchito yofunikira pamanetiweki a 5G. Makhalidwe ake apadera amapangitsa kukhala kofunika kwambiri kuti mukwaniritse ntchito za 5G zothamanga kwambiri, zotsika kwambiri, komanso zofalitsa zambiri.
1. Kufalikira koyenera komanso liwiro lotumizira
C-band ndi yapakati-gulu sipekitiramu, amene angapereke bwino bwino pakati Kuphunzira ndi deta kufala liwiro. Poyerekeza ndi otsika gulu, C-gulu akhoza kupereka apamwamba deta kufala mitengo; ndipo poyerekeza ndi magulu othamanga kwambiri (monga mafunde a millimeter), C-band ili ndi kuphimba kwakukulu. Izi zimapangitsa gulu la C-band kukhala loyenera kuyika maukonde a 5G m'matauni ndi akumidzi, kuwonetsetsa kuti ogwiritsa ntchito amalumikizana mwachangu pomwe akuchepetsa kuchuluka kwa masiteshoni omwe atumizidwa.
2. Zinthu zambiri zama sipekitiramu
C-band imapereka bandwidth yochulukirapo kuti ithandizire kuchuluka kwa data. Mwachitsanzo, bungwe la Federal Communications Commission (FCC) la ku United States linapereka 280 MHz ya mid-band spectrum ya 5G mu C-band ndi kuigulitsa kumapeto kwa 2020. Othandizira monga Verizon ndi AT&T adapeza kuchuluka kwa sipekitiramu. zogulitsa pamsika uwu, zomwe zimapereka maziko olimba a ntchito zawo za 5G.
3. Thandizani luso lapamwamba la 5G
Mawonekedwe afupipafupi a C-band amathandizira kuti azitha kuthandizira matekinoloje ofunikira mumanetiweki a 5G, monga MIMO yayikulu (zotulutsa zingapo) ndikuwongolera. Ukadaulo uwu ukhoza kupititsa patsogolo magwiridwe antchito, kukulitsa kuchuluka kwa maukonde, komanso kupititsa patsogolo luso la ogwiritsa ntchito. Kuonjezera apo, ubwino wa bandwidth wa C-band umathandiza kuti ikwaniritse zofunikira zothamanga kwambiri komanso zotsika kwambiri za ntchito zamtsogolo za 5G, monga augmented real (AR), virtual reality (VR), ndi Internet of Things (IoT). ).
4. Lonse ntchito padziko lonse
Mayiko ndi zigawo zambiri zagwiritsa ntchito C-band ngati gulu lalikulu la ma frequency a 5G. Mwachitsanzo, mayiko ambiri ku Ulaya ndi Asia amagwiritsa ntchito n78 band (3.3 mpaka 3.8 GHz), pamene United States amagwiritsa ntchito n77 band (3.3 mpaka 4.2 GHz). Kusasinthasintha kwapadziko lonse kumathandizira kupanga chilengedwe chogwirizana cha 5G, kulimbikitsa kugwirizana kwa zida ndi matekinoloje, ndikufulumizitsa kutchuka ndi kugwiritsa ntchito 5G.
5. Limbikitsani kutumizidwa kwa malonda a 5G
Kukonzekera momveka bwino ndi kugawa kwa C-band spectrum kwathandizira kutumizidwa kwa malonda a 5G network. Ku China, Unduna wa Zamakampani ndi Ukadaulo Wachidziwitso wasankha momveka bwino kuti 3300-3400 MHz (kugwiritsa ntchito m'nyumba mwalamulo), 3400-3600 MHz ndi 4800-5000 MHz monga magulu ogwiritsira ntchito machitidwe a 5G. Kukonzekera kumeneku kumapereka chitsogozo chomveka bwino cha kafukufuku ndi chitukuko ndi malonda a zipangizo zamakina, chips, ma terminals ndi zida zoyesera, ndikulimbikitsa malonda a 5G.
Mwachidule, C-band imagwira ntchito yofunika kwambiri pamanetiweki a 5G. Ubwino wake pakufalitsa, liwiro lotumizira, zida zowoneka bwino komanso chithandizo chaukadaulo zimapangitsa kukhala maziko ofunikira pakukwaniritsa masomphenya a 5G. Pamene ntchito yapadziko lonse ya 5G ikupita patsogolo, udindo wa C-band udzakhala wofunikira kwambiri, kubweretsa ogwiritsa ntchito kulankhulana bwino.
