Umbuzo oqhelekileyo kunxibelelwano olungenazingcingo kukuba ingaba i-5G isebenza nge-microwave okanye amaza erediyo na. Impendulo yile: I-5G isebenzisa zombini ezi zinto, njengoko ii-microwave ziyinxalenye yamaza erediyo.
Amaza erediyo aquka uluhlu olubanzi lweefrikhwensi ze-electromagnetic, ukusuka kwi-3 kHz ukuya kwi-300 GHz. Ii-microwave zibhekisa ngokukodwa kwinxalenye yefrikhwensi ephezulu yale spectrum, edla ngokuchazwa njengefrikhwensi ephakathi kwe-300 MHz kunye ne-300 GHz.
Iinethiwekhi ze-5G zisebenza kwiindidi ezimbini eziphambili zefrequency:
Iifrequencies ze-Sub-6 GHz (umz., 3.5 GHz): Ezi ziphantsi koluhlu lwe-microwave kwaye zithathwa njengamaza erediyo. Zibonelela ngokulinganisela phakathi kokugubungela kunye nomthamo.
IiMillimeter-Wave (mmWave) Frequencies (umz., 24–48 GHz): Ezi zikwayi microwave kodwa zithatha indawo ephezulu kakhulu kwi-radio wave spectrum. Zivumela isantya esiphezulu kakhulu kunye ne-latency ephantsi kodwa zinemiqolo emifutshane yokusasaza.
Ngokwembono yobuchwephesha, zombini iimpawu ze-Sub-6 GHz kunye ne-mmWave ziintlobo zamandla erediyo (RF). Igama elithi "microwave" lichaza nje ibhendi ethile ngaphakathi kwe-spectrum yamaza erediyo ebanzi.
Kutheni Oku Kubalulekile?
Ukuqonda lo mahluko kunceda ukucacisa amandla e-5G. Amaza erediyo asezantsi (umz., ngaphantsi kwe-1 GHz) agqwesile ekugubungeleni indawo ebanzi, ngelixa ii-microwave (ingakumbi i-mmWave) zibonelela nge-bandwidth ephezulu kunye ne-latency ephantsi efunekayo kwizicelo ezifana ne-augmented reality, iifektri ezikrelekrele, kunye nezithuthi ezizimeleyo.
Ngamafutshane, i-5G isebenza ngokusebenzisa amaza e-microwave, oludidi olukhethekileyo lwamaza erediyo. Oku kuyenza ikwazi ukuxhasa zombini uqhagamshelo olubanzi kunye nezicelo zangoku nezisebenza kakuhle.
