Umbuzo ovamile ekuxhumaneni okungenantambo ukuthi ngabe i-5G isebenza ngama-microwave noma amagagasi omsakazo. Impendulo ithi: I-5G isebenzisa kokubili, njengoba ama-microwave eyi-subset yamagagasi omsakazo.
Amagagasi omsakazo ahlanganisa ububanzi obubanzi bamaza kagesi, asukela ku-3 kHz kuya ku-300 GHz. Ama-microwave abhekisela ngqo engxenyeni yamaza aphezulu ale spectrum, evame ukuchazwa njengamaza aphakathi kuka-300 MHz no-300 GHz.
Amanethiwekhi e-5G asebenza kuzo zonke izinhlobo ezimbili zemvamisa eziyinhloko:
Amaza angaphansi kuka-6 GHz (isb., 3.5 GHz): Lawa awela ngaphakathi kobubanzi be-microwave futhi abhekwa njengamagagasi omsakazo. Anikeza ibhalansi phakathi kokumbozwa kanye nomthamo.
Amaza e-Millimeter-Wave (mmWave) (isb., 24–48 GHz): Lawa futhi angama-microwave kodwa athatha ingxenye ephezulu kakhulu ye-radio wave spectrum. Avumela isivinini esiphezulu kakhulu kanye nokubambezeleka okuphansi kodwa anezinga lokusabalala elifushane.
Ngokombono wobuchwepheshe, izimpawu ze-Sub-6 GHz kanye ne-mmWave zombili ziyizinhlobo zamandla e-radio frequency (RF). Igama elithi "microwave" limane lisho ibhendi ethile ngaphakathi kwe-spectrum yamagagasi omsakazo ebanzi.
Kungani Lokhu Kubalulekile?
Ukuqonda lo mehluko kusiza ekucaciseni amakhono e-5G. Amagagasi omsakazo anemvamisa ephansi (isb., ngaphansi kwe-1 GHz) asebenza kahle kakhulu ekumbozweni kwendawo ebanzi, kuyilapho ama-microwave (ikakhulukazi i-mmWave) eletha i-bandwidth ephezulu kanye nokubambezeleka okuphansi okudingekayo kuzinhlelo zokusebenza ezifana ne-augmented reality, amafektri ahlakaniphile, kanye nezimoto ezizimele.
Ngamafuphi, i-5G isebenza kusetshenziswa amaza e-microwave, okuyisigaba esikhethekile samagagasi omsakazo. Lokhu kuyenza ikwazi ukusekela kokubili ukuxhumana okubanzi kanye nezinhlelo zokusebenza ezisezingeni eliphezulu nezisezingeni eliphezulu.
