Emhlabeni wanamuhla oxhumene, ukuxhumana kwe-inthanethi okuthembekile nokushesha kakhulu kubalulekile kuwo wonke amabhizinisi. Ngokufika kwe-4G kanye nobuchwepheshe obuvelayo be-5G, ukukhetha imodemu efanele sekubaluleke kakhulu.
Amanethiwekhi e-Broadband e-5G ayinkambiso yakamuva kwezobuchwepheshe, ehlinzeka ngoxhumano olufika ku-10Gbps ekusebenzeni kahle. Ngalezi zivinini, i-5G inikeza ukuxhumana okusheshayo kune-fiber optics, okuyenza idume kakhulu emakethe.
Ngokusho kwe-Allied Market Research, imakethe yemodemu yomhlaba wonke ye-5G yalinganiselwa ku-USD 845.3 wezigidi ngo-2021 futhi kubikezelwa ukuthi izoba yizigidi eziyizinkulungwane ezingama-USD 10.8 ngo-2031, ikhula ngesilinganiso sokukhula sonyaka esiyinhlanganisela. (CAGR) ka-29.1% kusukela 2022 kuya 2031.
Lokhu okuthunyelwe kuzoveza umehluko oyinhloko phakathi kwamamodemu e-4G ne-5G, kanye nokugqamisa izici ezibalulekile okufanele zicatshangelwe lapho ukhetha amamodemu ukuze abathengi bakwazi ukuzibeka endaweni yabo ukuze baphumelele!

Umthelela wemodemu efanele kumabhizinisi amancane
Njengoba amabhizinisi amancane amaningi eqhubeka nokuthembela ekuxhumekeni kwe-inthanethi okuphumelelayo ukuze afinyelele kumakhasimende awo, ukukhetha imodemu engcono kakhulu kungaba nomthelela omkhulu ekukhiqizeni kwawo, ulwazi lwamakhasimende, nokusebenza kahle kukonke.
Imodemu ethembekile nesebenza kakhulu ingathuthukisa kakhulu ukusebenza kwamabhizinisi amancane. Inika amandla isivinini sokulanda nokulayisha ngokushesha, inkomfa ngevidiyo engenazihibe, ukuthengwa kwe-inthanethi okushelelayo, nokuxhumana okuthuthukisiwe.
Ngaphezu kwalokho, imodemu eqinile iqinisekisa ukufinyelela okungaphazamiseki ezinsizeni zamafu, ukudluliswa kwedatha, nokuxhumana okuthembekile okuvumela amabhizinisi amancane ukuthi ahlale encintisana endaweni yanamuhla yedijithali.
Njengomnikazi webhizinisi, ukutshala imali kumodemu efanelekile kungakhuphula umkhiqizo, ukwaneliseka kwamakhasimende, futhi ekugcineni ukukhula kwebhizinisi. Njengomphakeli wamamodemu, ngakolunye uhlangothi, ukukwazi ukusiza abathengi ekutholeni isixazululo esivumelana kangcono nezidingo zabo kubalulekile ekuqinisekiseni ukwaneliseka kwamakhasimende nokukhula kwebhizinisi.
Ukuqonda amamodemu e-4G ne-5G
Amamodemu amadivayisi axhuma kumhlinzeki wakho wesevisi ye-inthanethi (ISP) futhi anike amandla ukufinyelela ku-inthanethi. Amamodemu ahumusha idatha yedijithali isuka ku-ISP yakho iye kwifomethi yedivayisi yakho, njengamakhompyutha, Smartphones, nezibhebhe, qondani.
Izinhlobo ezahlukene zamamodemu
Lapho ukhetha imodemu, kubalulekile ukuqonda izinhlobo ezahlukene ezitholakala emakethe. Amamodemu ahlukahlukene atholakalayo afaka ikhebula, i-DSL, i-fiber, ne-wireless.
Amamodemu ekhebula
Imodemu yekhebula iyithuluzi elivumela ikhompuyutha ukuthi ixhumane ne-ISP ngoxhumo locingo lwasendlini. Imodemu yekhebula empeleni ingumhumushi wedijithali. Ithola idatha ku-ISP yakho, iyihumushele kokuthile umzila wakho ongakwazi ukukuqonda, bese umzila ube usukhipha isignali kumadivayisi akho.
Amamodemu ekhebula asebenza ngokuxhuma izintambo ze-coaxial futhi Intambo ye-CAT 5 (Ethernet). kusuka kumodemu kuya kukhompuyutha noma umzila wenethiwekhi.
Amamodemu e-DSL
A Imodemu ye-DSL ixhuma ikhompuyutha nesevisi yenkampani yocingo ye-digital subscriber line (DSL) ukuze uthole ukufinyelela ku-inthanethi.
Nakuba i-DSL ishesha kunokudayela kwe-analog, ihamba kancane kunesevisi yekhebula. Amamodemu e-DSL axhumeka kukhompuyutha noma umzila nge-Ethernet. Nokho, amanye amamodemu e-DSL angaxhuma kukhompuyutha eyodwa nge-USB. Ngaphezu kwalokho, amamodemu e-DSL avame ukuhlanganiswa nawo ama-routers.
I-Fiber modem
I-Fiber optic modem (i-FOM) iyisixhumi esibonakalayo esixhumanisa izinto zikagesi namanethiwekhi e-inthanethi. Basebenzisa izintambo ze-fiber optic esikhundleni sezintambo zethusi njengamamodemu e-DSL ukuze badlulise amasignali.
In I-fiber optic modem, isignali ye-inthanethi idluliselwa ngezintambo ze-fiber optic ku-FOM; imodemu ibe isiguqula isignali ye-inthanethi ibe idatha ye-elekthronikhi edluliselwa esisetshenziswa se-elekthronikhi. Ngakho-ke idatha ye-FOM ingadluliselwa kusuka ku-inthanethi iye amadivaysi kagesi futhi okuphambene nalokho.
Amamodemu angenantambo
Imodemu engenantambo idlula amasistimu ocingo bese ixhuma ngqo kunethiwekhi engenazintambo ukuze ifinyelele ku-inthanethi ehlinzekwa yi-ISP.
Amamodemu angenantambo dlulisa idatha usebenzisa amaza kagesi. Ngokungafani namamodemu e-analog, ahlinzeka ngoxhumano lwenethiwekhi olusheshayo noluthembekile. Abasebenzisi bangafinyelela i-inthanethi ngokushesha okufika izikhathi eziyi-100 kunamamodemu e-analog.
Ukwehlukanisa phakathi kwamamodemu e-4G kanye ne-5G
I-4G iyisizukulwane sesine seselula ubuchwepheshe benethiwekhi futhi ingeyangaphambili ye-5G. Womabili amamodemu e-4G ne-5G anikezela ngoxhumano okungenantambo kodwa ahluka ngesivinini, ukumbozwa, nokubambezeleka.
Amamodemu e-4G ukunikeza ukufinyelela kwe-inthanethi okusheshayo, okuwenza afanele amabhizinisi amaningi amancane. Ngakolunye uhlangothi, amamodemu e-5G anikezela ngesivinini esiphezulu kakhulu, ukubambezeleka okuphansi, kanye nomthamo onyukile okuwenza alungele amabhizinisi athembele kakhulu ekucutshungulweni kwedatha yesikhathi sangempela, izinsiza zamafu, noma amadivayisi we-IoT.
With Amamodemu e-5G, umuntu uthola ukubambezeleka okuphansi okungaphansi kwama-millisecond amahlanu, kuyilapho i-4G ine-latency efika ku-98ms. Ukubambezeleka okuphansi ku-5G kuvumela isivinini sokulanda ngokushesha. Ngenkathi i-4G inesivinini sokulanda esifika ku-1Gbps, i-5G inyusa lokhu ngokuphindwe kashumi kuya ku-10Gbps.
Omunye umehluko obalulekile phakathi kwe-4G ne-5G yiziteshi zabo eziyisisekelo; I-4G idlulisa amasiginali ukusuka kumbhoshongo weseli njengabanduleli bayo, kuyilapho i-5G isebenzisa yomibili imibhoshongo yamaseli nobuchwepheshe beselula obuncane ngesivinini esisheshayo namabhendi e-mmWave frequency.
Izici ezibalulekile okufanele uzicabangele lapho uthenga imodemu
Ngaphambi kokuthenga imodemu, amabhizinisi kufanele ahlole izidingo zawo kanye nobukhulu besikhathi esizayo, bese enquma phakathi kwamamodemu e-4G ne-5G. Ezinye izici okufanele uzicabangele lapho ukhetha imodemu zihlanganisa:
Izici zemodemu
Lapho ukhetha imodemu ehamba phambili, cabangela isivinini sokulanda nokulayisha, ukusebenzisana kwenethiwekhi, izici zokuphepha, kanye nokufaka kalula. Bheka amamodemu anikeza izici ezithuthukisiwe njengezimbobo ze-Ethernet eziningi, i-dual-band Wi-Fi, futhi asekele izivumelwano zakamuva ze-inthanethi.
Inani
Qhathanisa amanani phakathi kwamamodeli emodemu ahlukene nemikhiqizo. Nakuba ukuhlala ngaphakathi kwesabelomali sakho kubalulekile, beka phambili ikhwalithi nokwethembeka kunezindleko kuphela. Ukutshala imali kumkhiqizo ohloniphekile onerekhodi eliqinisekisiwe kungakusindisa ezinkingeni ezingaba khona zokuxhuma noma ukushintshwa okuvamile.
Njengebhizinisi lokudayisa elifuna ukuthengisa amamodemu, kufanele ubheke izisekelo zabathengi bakho kanye nesitoko sezinhlobo ezahlukene zamamodemu ezinhlotsheni zamanani ezehlukene ukuze ubhekelele zonke izintandokazi zabathengi.
Ukusebenza kwesikhathi eside
Njengebhizinisi elincane, qinisekisa ukuthi imodemu yakho ihambisana nezidingo zakho zesikhathi esizayo kanye nentuthuko yezobuchwepheshe. Cabangela ukuhambisana kwemodemu namazinga e-inthanethi ezayo kanye nekhono layo lokusekela izimfuneko zomkhawulokudonsa njengoba ibhizinisi lakho likhula.
Ukusetshenziswa
Lapho ukhetha amamodemu angcono kakhulu e-4G noma e-5G, umnikazi webhizinisi kufanele acabangele ukusetshenziswa kwangempela kwe-inthanethi ebhizinisini lakhe. Uma ungumsebenzisi ophakeme noma omaphakathi onezinhlelo zokusebenza eziphethwe ngamafu, inkomfa ngevidiyo, nokushintshisana kwedatha okuqhubekayo, khetha i-Mbps ephezulu enesilinganiso somkhawulokudonsa esingu-2:1.
Uma ungumsebenzisi ophansi noma ovamile futhi usebenzisa i-inthanethi kuphela nge-imeyili nosesho oluyisisekelo, ungaba nesilinganiso somkhawulokudonsa ongu-3:1.
Isiphetho sendaba
Uxhumano lwe-inthanethi oluthembekile nolushesha kakhulu lubalulekile kuwo wonke amabhizinisi emhlabeni wanamuhla oxhumene. Ngokufika kwe-4G kanye nobuchwepheshe obuvelayo be-5G, ukukhetha imodemu efanele sekubaluleke kakhulu.
Ngaphambi kokukhetha imodemu ye-4G noma ye-5G ehamba phambili, kubalulekile ukuqonda umthelela amamodemu anawo kumabhizinisi amancane kanye nezinhlobo ezahlukene zamamodemu emakethe.
Ukukhetha imodemu ehamba phambili kungaba nomthelela omkhulu ekukhiqizeni, ulwazi lwekhasimende, nokusebenza kahle kukonke ebhizinisini.
Kunezinhlobo ezahlukene zamamodemu, okuhlanganisa ikhebula, i-DSL, iFiber, namamodemu angenawaya. Futhi, ukukhetha imodemu ye-4G ne-5G ehamba phambili, umuntu udinga ukucabangela izici, amanani, ukusetshenziswa, nokusebenza kwesikhathi eside.
Kuzo zonke izidingo zakho zemodemu ye-4G ne-5G, kanye nezinye izesekeli zobuchwepheshe, vakashela Cooig.com.
