Ngubani 5G (Umgca Ophambili Womthetho Wosetyenziswa Wesikhundla)

5G (Umgquqo Omtsha Wokuxhasa Lomsebenzi Olunyelewe Lokusebenzisa Amaphonethi), okanye 5G, yimigca yakwesikhashana esiqhutywa ngokuthi kufanele ukhululekileyo, ukusuka oluphenyo, kunye nokuvumelaniswa okukhedamene. Yiyindlela yokusebenza lemfundeweni yokuhlanganisa abantu, amasinyathi kunye nezinto ezinayo.

Umgqadi womvume weTelekomunikethi yaseInternational (ITU) ubheke amathathu okubanzi okanye amaxwebhu ezikhoyo lokusebenza kwi-5G, ngokusho i-Enhanced Mobile Broadband (EMBB), i-Ultra Reliable Low Latency Communication (URLLC), kunye ne-Massive Machine Class Communication (mMTC). I-Enhanced Mobile Broadband (EMBB) usetyenziswa ngokuphambili ukuvumela uphawuli wemfundo wesintuthuko somphakathi sokugcina, uhlola imisebenzi engenayo yokulayishwa kwesintuthuko esintuthukiso; I-Ultra high reliability low latency communication (URLLC) usetyenziswa ngokuphambili ukuvumela amaxwebhu eziphambili zokuhlola nokuhlonishwa kwezinye izindlela zokusebenza ezidingekayo ukusetyenziswa nokuhlola, njengomculo wendlela yokuziphindaphinda, i-remote healthcare, kunye ne-autonomous driving; I-Massive Machine Class Communication (MMTC) usetyenziswa ngokuphambili ukuvumela amaxwebhu ekufunekiyo yokuhlola nokuhlola emazweni yezinto ezinomsindo, ezindaweni zokugcina, kunye nokuhlola kwindawo yokudibanisa.

Ukukhuthazeka kwezinye izindlela ezidingekileyo ne5G, amanqaku angaphambili okugcina nge5G akulindeleke. ITU yalayishwa amanqaku angaphezulu amashumi ngemibuzo wokugcina nge5G, apho i-high speed, i-low latency kunye ne-large connectivity zizikhono ezindala zokuthiwa ne5G. Ukuphakamiswa kwesicelo sasenzi 1Gbps, ukuphenya kukho ngokushesha 1ms, kunye nokuphakamiswa kokuthiwa kwamanje ephakeme 1 million connections per square kilometer.
