Cishe uke waqaphela ukuthi ifoni yakho ishesha kakhulu ngenxa ye-5G, kodwa ngemuva kwezigcawu, impi yobuchwepheshe ethule iyaqala. Amanethiwekhi akha isisekelo sokuxhumana kwethu, i-2G edumile kanye ne-3G kamuva, ayasuswa . Akukhona ukuthi ayahluleka; ukuthi abaqhubi banqume ukuwakhipha ukuze benze isikhala sobuchwepheshe obusheshayo nobusebenza kahle kakhulu, bekhulula lawo ma-frequency asegolide elicwengekile manje lokusetshenziswa kokuxhumana okusha.
Inkinga iwukuthi, nakuba lokhu kungase kungabonakali kumsebenzisi ojwayelekile, kuyindaba ebuhlungu kakhulu emhlabeni we -Internet of Things (IoT) . Kunezinkulungwane zamadivayisi, kusukela kuma-alamu amadala kuya kumamitha ahlakaniphile, akhuluma ulimi lwala manethiwekhi e-IoT aphelelwe yisikhathi kuphela . Uma engabuyekezwa, azobe engasasebenziseki nhlobo ngobusuku obubodwa, okudala isimo abanye abasiqhathanisa kakade nesiphazamisi se-Y2000K , kodwa kulokhu kugxile kwihadiwe.
Kungani la manethiwekhi avaliwe?
Isizathu esiyinhloko siwubuchwepheshe kanye nezomnotho kuphela. Ububanzi bomsakazo bulinganiselwe, futhi ukugcina ingqalasizinda endala kubiza kakhulu futhi amandla awasebenzi kahle . Ngaphezu kwalokho, lawa manethiwekhi asengozini enkulu yobuthakathaka bokuphepha kunalawo amanje. Ngokuvala i-2G ne-3G, abaqhubi bangasebenzisa kabusha ama-band angu-900 MHz kanye no-2.100 MHz ukuze bandise ukumbozwa kwe-4G kanye ne-5G , ikakhulukazi ezindaweni zasemakhaya lapho isignali isabuthakathaka khona.
Imephu yokucima ugesi: Kwenzeka nini endaweni ngayinye?
Ukuvalwa akufani; kufana kakhulu ne-mosaic lapho izwe ngalinye liqhubeka ngejubane lalo. E- United States, eSwitzerland nase-Australia , inqubo isiphelile cishe, kanti iningi lalawa ma-technologies selivele lingasasebenzi. EYurophu, isimo siyahlukahluka kakhulu:
- I-Germany: Inethiwekhi ye-3G ibilokhu ingumlando kusukela ngo-2021. Ngokuphathelene ne-2G, i-Deutsche Telekom kanye ne-Telefónica bahlela ukuyivala ngo-2028, yize i-Vodafone kungenzeka ukuthi isilethe isikhathi sayo. Kodwa-ke, ngezinhlelo ezibalulekile ze-IoT, ingqalasizinda izohlala ikhona kuze kube... Januwari 2031.
- I-Spain: Isu lapha ukuqala ngokuvala i-3G (ngezinhlelo ezizoqhubeka kuze kube ngu-2027) nokugcina i-2G isikhathi eside. Abasebenzi abanjengo-Orange no-Vodafone sebevele benze intuthuko ekuqedeni i-3G. Kodwa-ke, uhulumeni kanye nabasebenzi balindele ukuthi inethiwekhi ye-2G izoqhubeka isebenza. kuze kube sekupheleni kuka-2030 ngenxa yokuthembela ezinsizeni ezibalulekile.
- Amanye amazwe aseYurophu: E-Austria, i-3G isivele ivaliwe futhi i-2G izovalwa phakathi kuka-2028 no-2030. ISweden neNorway zinolaka kakhulu futhi zihlose ukuthi zombili izinethiwekhi zisulwe yi- ngasekupheleni kuka-2025.
Ingozi yangempela: Amadivayisi azophelelwa yisikhathi
Yilapho izinto ziba nzima khona. Asikhulumi ngokushintsha i-smartphone, kodwa ngehadiwe efakwe engqalasizinda. Izinhlelo ze-Telecare kanye nama-alamu asekhaya amadala avame ukuthembela ku-2G; uma inethiwekhi iwa, usizo ngeke lufike. Okufanayo kusebenza nasezikhumulweni zokukhokha amakhadi ezindaweni zasemakhaya , lapho isignali ye-2G ngezinye izikhathi kuyiyona kuphela etholakalayo, okubeka engcupheni izinkokhelo zedijithali emabhizinisini azimele.
Inkinga eyodwa ebaluleke kakhulu ama-lifti . Imithetho ifuna ukuthi babe nokuxhumana okubili nezikhungo zokusindisa futhi bazihlole njalo emahoreni angu-72. ESpain, izwe laseYurophu elinezi-lifti eziningi, ingxenye yesigidi sazo ineminyaka engaphezu kwengu-20 ubudala futhi isebenzisa amamojula e-2G. Uma kwenzeka ugesi unqamuka ngaphandle kokuthi ihadiwe ithuthukiswe, lawa ma-lifti azosuswa ngokusemthethweni .
Inkinga ye-eCall ezimotweni
Uhlelo lwe-eCall, oluyimpoqo e-EU kusukela ngo-2018, lushayela ngokuzenzakalelayo izinsizakalo eziphuthumayo (112) uma kwenzeka ingozi enkulu. Izimoto eziningi ezixhunyiwe ezenziwe phakathi kuka-2018 no-2024 zisebenzisa amanethiwekhi e-2G/3G kulo msebenzi. Abakhiqizi abanjengoCUPRA noRenault bahlaziya umthelela. Ngenkathi amamodeli amasha esevele esebenzisa izinsizakalo zangasese noma amanethiwekhi e-4G/5G (NG-eCall), amamodeli amadala angadinga izibuyekezo zesofthiwe emoyeni (OTA) noma, esimweni esibi kakhulu, ukushintshwa kwemodyuli yokuxhumana.
Indlela yokulungiselela ushintsho?
Uma uphatha inqwaba yamadivayisi e-M2M, isinyathelo sokuqala ukubala inani. Akwanele ukuthi idivayisi ibe "yi-4G" nje, ngoba amamodeli amaningi amadala asebenzisa i-4G ukuthola idatha kodwa athembele ku-2G ukuthola izwi (ukuntuleka kokuhambisana kwe -VoLTE ). Ukuthuthela ezindinganisweni zesimanje ezenzelwe i-IoT kubalulekile.
- I-LTE-M: Ilungele ama-tracker kanye nezinto ezigqokwayo ngenxa yokusebenzisa kwayo amandla aphansi kanye nobubanzi bayo obude.
- I-NB-IoT (i-Narrowband IoT): Ilungele izinzwa eziqinile ezindlini ezingaphansi komhlaba noma ezindaweni ezikude ngenxa yayo ukungena kwesignali okweqile.
- I-5G: Kuzinhlelo zokusebenza ezidinga isikhathi sangempela kanye nenani elikhulu ledatha, njenge-Industry 4.0.
Kubalulekile ukuqaphela ukuthi i-SIM khadi ngokwayo akuyona inkinga, njengoba ama-SIM e-M2M esimanje esebenzisa ubuchwepheshe obuningi. Inkinga yi- modem noma i-hardware firmware , okuyiyona edinga ukubuyekezwa ngempela ukuze kugwenywe ukulahlekelwa ukuxhumana.
Ukushintshela ezweni elingenayo i-2G ne-3G akunakugwenywa futhi, ekugcineni, kuyazuzisa ngenxa yokusebenza kahle nokuphepha okwandisiwe. Kodwa-ke, kudinga ukuhlela okuphuthumayo ukuqinisekisa ukuthi izinsizakalo ezibalulekile njengokunakekelwa kwezingcingo, ukuphepha kwe-elevator, kanye nezingcingo eziphuthumayo eceleni komgwaqo aziphazanyiswa, okuqinisekisa ukuthi yonke imvelo ithuthela ezindinganisweni zokuxhumana zesimanje ngaphambi kokuba ama-antenna akudala amiswe unomphela.
