Ngaba ihlobo lixesha elishushu lokukhutshwa kwemisebenzi yangaphandle?
Ixesha lasehlotyeni ngokuqhelekileyo libhekwa "njengexesha eliphantsi" lomsebenzi wezoshishino. Abanye abantu baseholideyini, abanye abangxamanga ukuthenga iimpahla ezithile kuba bengekho kwimeko efanelekileyo, kwaye abathengisi kunye nababoneleli ngeenkonzo ngokwabo bakhetha ukuphumla ngeli xesha.
Ngoko ke, ihlobo labasebenzi bangaphandle okanye iingcali ze-IT ezizimeleyo, umzekelo, "abalawuli benkqubo ezayo," kuthathwa njengexesha elingasebenziyo ...
Kodwa ungajonga kwelinye icala. Abantu abaninzi bafudukela kwiindawo zeeholide, abanye bafuna ukuseta unxibelelwano kwindawo entsha, abanye bafuna ukufikelela okuzinzile ukusuka naphi na eRashiya (okanye ubuncinci ukusuka kwi-suburb ekufutshane). Ukubonisana, uqhagamshelo kunye neenkonzo zoqwalaselo, umbutho wokufikelela kude, umzekelo, kwikhompyuter yasekhaya, ukusetyenziswa kweenkonzo zefu - konke oku kunokuba yimfuneko.
Akufanele ubhale ngokukhawuleza zonke iinyanga ezintathu zasehlotyeni njengento engenanzuzo, kodwa kungcono, kubaqalayo, ukuba ubuncinane ukhangele kwaye ubone ukuba ngubani oya kufuna ntoni kwindawo enjalo. Umzekelo, unxibelelwano nge-LTE.
"Umsindisi"
Abahlali bezixeko ezikhulu bonanelwa ngokwemigangatho yonxibelelwano. Banokhetho oluninzi lokufikelela kwi-Intanethi nangaphaya kocingo, kubandakanywa umgca ozinikeleyo we-fiber-optic, i-Wi-Fi yasimahla naphi na apho kunokwenzeka, kunye nonxibelelwano lweselula oluthembekileyo oluvela kubaqhubi abakhulu beeselula.
Ngelishwa, xa uqhubeka usuka kumaziko ommandla, amathuba ambalwa onawo okufumana unxibelelwano olukumgangatho ophezulu. Ngezantsi siza kujonga iindawo apho unxibelelwano lwe-LTE luya kunceda.
Xa umboneleli ebuyela emva
Ababoneleli ngenkonzo basekhaya abasoloko βbekwicala leteknoloji yamaza.β Ngokuqhelekileyo kwenzeka ukuba izixhobo zomboneleli, iziseko zophuhliso kunye nomgangatho weenkonzo azikho nto inomdla.
Masiqale ngeziseko zophuhliso. Ukuzisa i-fiber optic GPON kuwo onke amagumbi ezilalini okanye kwindlu nganye ekwilali kuseliphupha.
Ababoneleli abancinci bahluphekile kunabakhulu, abo bamaphondo bahluphekile kunabo bakwikomkhulu, banezibonelelo ezimbalwa zokudala isiseko esiphuhlisiwe. Ngelo xesha, amandla okuthenga kwiindawo zokuhlala ezincinci ziphantsi kunezixeko ezinkulu (ngaphandle kwezinto ezinqabileyo). Ngoko ke, ukutshala imali "kwiingcingo" kaninzi akukho mathuba okubuyisela kutyalo-mali.
Kwezinye iimeko, abasebenzisi kufuneka baneliseke ngoqhagamshelwano olusekelwe kwi-ADSL kunye nesantya esifanelekileyo kunye nobuchule. Kodwa nalapha sithetha malunga neendawo zokuhlala ezineziseko zophuhliso esele zimiselwe. Iidolophana zeeholide ezisanda kwakhiwa, izinto ezikude ezifana neendawo zokugcina iimpahla, indawo yemizi-mveliso ihlala ingenalo naluphi na unxibelelwano nehlabathi langaphandle, ngaphandle kwe βetherealβ.
Ukuba sithetha ngezixhobo, amandla ahlala ethozamile kakhulu. Ukuthenga izixhobo ezitsha zonxibelelwano, kufuneka ufumane imali eyongezelelweyo. Kodwa oku akusoloko kusenzeka, ngakumbi kuba iimali ezifunekayo (kuxhomekeke kwiqondo lokuphelelwa lixesha kwezithuthi zangoku) zinokuba nomtsalane kakhulu.
Enye ingongoma ebalulekileyo yinqanaba lenkonzo. βUkunqongophala kwabasebenziβ asiyonto inqabileyo ngolo hlobo. Kuhlala kukho ukunqongophala kweengcali ezilungileyo, kwaye izixeko ezinkulu okanye "ukusebenza ngaphandle" kwenza kube lula ukufumana umvuzo ophezulu kunomboneleli wendawo.
Kufanelekile ukukhankanya isikhundla somntu oyedwa kwimarike. Ukuba kukho umnikezeli we-Intanethi omnye kuphela kwisithili sonke, unokuyalela kungekuphela kwamaxabiso, kodwa kunye nenqanaba lenkonzo. Kwaye ke iingxoxo eziphuma kolu ngcelele: βBaza kuya phi (abathengi) kuthi?β ibe sisiqubulo esiphambili xa kulungiselelwa abathengi.
Akunakuthiwa zonke ezi ngxaki zavela kuphela ngenxa yokubawa komntu, ukungafuni ukwenza nantoni na kunye nezinye izono ezifayo. Hayi akunjalo. Kuphela nje ukuba uqoqosho, ubugcisa okanye enye imeko ayivumeli ukuba silungise ngokukhawuleza yonke imiba.
Ngoko ke, enye indlela yokufikelela emoyeni nge-LTE lithuba elihle lokuphucula umgangatho weenkonzo ngokutshintsha umnikezeli.
"Tumbleweed"
Baninzi kakhulu abantu abanezikhundla zabo, uhlobo lomsebenzi, kunye nendlela yokuphila elula edityaniswa nokuhamba rhoqo.
Ukuba uhamba ngemoto, ke kungcono ukulibala ngokulula malunga nokhetho lonxibelelwano olunentambo. Kodwa kuxa uhamba apho ngamanye amaxesha ufuna ukufikelela kwi-Intanethi ekumgangatho ophezulu. Ngokomzekelo, kumakhi, umakhi, umthengisi, uchwepheshe wokulungisa izixhobo, kunye neeblogi, kwaye ngokubanzi bonke abo kufuneka badibanise kwimithombo yenethiwekhi ngezikhathi ezithile endleleni.
Ungasebenzisa unxibelelwano lweselula kwisixhobo ngasinye (kwaye uhlawule imali kuyo yonke le nto), kodwa kulula kakhulu kwaye ukonga ngakumbi ukuba ne-LTE router kwimoto kwaye uqhagamshele izixhobo eziphathwayo nge-Wi-Fi.
Qaphela:. Kubantu abahamba rhoqo ngemoto, sinokucebisa izixhobo eziphathwayo, ezifana ne-LTE Cat.6 Wi-Fi router AC1200 (imodeli WAH7706) ephathekayo. Ngobukhulu babo obuncinci, ii-router ezincinci ezinjalo ziyakwazi ukubonelela ngonxibelelwano oluthembekileyo kwizixhobo ezininzi.
Umzobo 1. I-LTE ephathekayo ye-router AC1200 (imodeli WAH7706).
Ngaba i-Intanethi ayikahanjiswa?
Nangona kunjalo, nakwizixeko ezikhulu kukho iindawo apho ukufikelela kwi-Intanethi kunzima okanye kungabikho ngokupheleleyo. Umzekelo omkhulu kukwakha. Akunakwenzeka ukufaka i-intanethi ye-intanethi, kodwa unxibelelwano luyafuneka ngoku, umzekelo, ukucupha ividiyo.
Ngamanye amaxesha iofisi yokuthengisa iiflethi zesikhashana isebenza kwiipropati ezingagqitywanga, ezifuna ukufikelela okuphezulu kwimithombo yenethiwekhi ekude.
Imeko efanayo ivela kumaziko akwindawo yoshishino. Ngenxa yemigama emide kunye nenani elincinci labathengi, akunanzuzo nje ukuqhuba intambo. I-LTE inceda kwindawo yayo ebanzi.
Kwaye, ngokuqinisekileyo, i-LTE ifunwa kwiilali zeeholide. Ubume bexesha lokusetyenziswa kwenkonzo, xa kukho abantu abaninzi kwii-dachas ehlobo kwaye kungekho mntu ebusika, kwenza ezi zinto zingathandeki "kubaboneleli ngeengcingo." Ngoko ke, i-router ye-LTE sele ithathwa njenge "impawu ze-dacha" njenge-flip-flops okanye i-garden watering can.
Ucingo olungenakunqunyulwa
Ukufikelela ngeentambo zomzimba kunika unxibelelwano oluzinzile, oluthembekileyo (kwizinga elifanelekileyo lezobuchwepheshe), kodwa kunomda omnye - yonke into isebenza de intambo yonakaliswe.
Thatha, umzekelo, inkqubo yokucupha ividiyo. Ukuba imifanekiso evela kwiikhamera irekhodwa kude nge-Intanethi, ngoko kubaluleke kakhulu ukuba ube noqhagamshelwano oluzimeleyo. Kule nkalo, ukufikelela kweengcingo akusiso isisombululo esihle.
Jonga ivenkile, i-salon yeenwele okanye enye ishishini elincinci elihlala kwindawo yokuhlala kumgangatho wokuqala wesakhiwo sokuhlala. Ukuba ikhebula livela naphi na, nokuba lincinci, kwindawo efikelelekayo, umzekelo, ukudlula kwipaneli yombane, inokunqunyulwa kwaye inkqubo yokujonga ividiyo iya kuyeka ukudlulisa. Kwaye, nokuba kukho ikopi kwimithombo yangaphakathi, umzekelo, kwi-hard drive yokurekhoda, konke oku: zombini iikhamera kunye nerekhodi zinokukhutshazwa okanye zithathwe kunye nawe, zigcine i-incognito epheleleyo.
Kwimeko yonxibelelwano olungenacingo, kunokwenzeka ukuba uphazamise ukufikelela kwiNethiwekhi (ukuba awucingi "i-jammers" ekhethekileyo kuphela emva kokungena kwindawo. Ukuba unakekele ukunikezelwa kwamandla okuzimela, ubuncinci ixesha elifutshane lokusebenza, ngoko kwiimeko ezininzi kunokwenzeka ukurekhoda umzuzu wokungena, onokuthi unikezelwe kumapolisa, inkampani ye-inshurensi, umbutho wokhuseleko, njalo njalo. .
Enye into ephazamisayo kukungaphumeleli kokutshintsha kunye nezinye izixhobo "zabasebenzisi abaqhelekileyo", umzekelo, ngenxa yephutha labakhi abangenamakhono kunye "nabachwephesha" nje abakwazi kwaye banako ukudala iingxaki ezahlukeneyo kubamelwane.
Kwiimeko ezinjalo, unxibelelwano olungenazingcingo nge-LTE lunokubaluleka.
Yintoni amandla e-LTE
Isishunqulelo se-LTE simele i-Long Term Evolution. Enyanisweni, oku akusiyo umgangatho, kodwa isalathiso sophuhliso esilungiselelwe ukuphendula umbuzo: "Yintoni ecetywayo xa amandla e-3G engasanele?" Kwacingelwa ukuba i-LTE iya kusebenza ngokwemigangatho ye-3G, kodwa emva koko uphuhliso lwaba banzi.
