Umbuzo oqhelekileyo kunxibelelwano olungenazingcingo kukuba ingaba i-5G isebenza ngokusebenzisa ii-microwaves okanye amaza erediyo. Impendulo yile: I-5G izisebenzisa zombini, njengoko ii-microwaves ziseti yamaza erediyo.
Amaza kanomathotholo aquka uluhlu olubanzi lweefrikhwensi zombane, ukusuka kwi-3 kHz ukuya kuma-300 GHz. Ii-Microwaves zibhekisa ngokuthe ngqo kwisahlulo esiphezulu se-frequency yalo mboniso, ochazwa ngokuqhelekileyo njengezandi phakathi kwe-300 MHz kunye ne-300 GHz.
Uthungelwano lwe-5G lusebenza kwiindidi ezimbini eziphambili zefrikhwensi:
I-Sub-6 GHz Frequencies (umz., 3.5 GHz): Ezi ziwela phakathi koluhlu lwe-microwave kwaye zithathwa njengamaza erediyo. Banikezela ngolungelelwaniso phakathi kokhuseleko kunye namandla.
IMillimeter-Wave (mmWave) Iifrikhwensi (umz., 24–48 GHz): Ezi zikwazii-microwaves kodwa zihlala esona siphelo siphezulu samaza kanomathotholo. Benza isantya esiphezulu kunye ne-latency ephantsi kodwa banoluhlu olufutshane lokusasaza.
Ngokwembono yobugcisa, zombini i-Sub-6 GHz kunye ne-mmWave iisignali ziintlobo zamandla kanomathotholo (RF). Igama elithi "microwave" lichaza nje ibhendi ethile ngaphakathi kwimaza yerediyo ebanzi.
Kutheni Le nto Ibalulekile?
Ukuqonda lo mahluko kunceda ukucacisa amandla e-5G. Amaza onomathotholo asezantsi (umzekelo, ngaphantsi kwe-1 GHz) ayagqwesa kukhuselo lwendawo ebanzi, ngelixa ii-microwaves (ingakumbi i-mmWave) zihambisa i-bandwidth ephezulu kunye ne-latency ephantsi efunekayo kwizicelo ezifana nenyani eyandisiweyo, iifektri ezihlakaniphile, kunye nezithuthi ezizimeleyo.
Ngamafutshane, i-5G isebenza kusetyenziswa ii-microwave frequencies, eziludidi olukhethekileyo lwamaza erediyo. Oku kuyenza ikwazi ukuxhasa uqhagamshelo olubanzi kunye nokusika, usetyenziso oluphezulu.
