Siqhubeka nengxoxo mayelana nama-nuances futhi sincoma imikhuba engcono kakhulu. Isiteshi sokulondoloza - siyadingeka futhi kufanele sibe njani?
Isingeniso
Kuze kube yisikhathi lapho uqala ukusebenza ukude ngokujulile futhi isikhathi eside, awucabangi ngezinto eziningi. Isibonelo, indlela yokuqinisekisa ukululama okusheshayo kwesistimu. Ungayithola kuphi ikhompuyutha ukuze ubuyisele ephukile uma udinga ukuxhuma emsebenzini hhayi ngosuku, kodwa njengamanje. Futhi ekugcineni, yini okufanele uyenze uma uxhumano kulahleka?
Ngaphambi kokushintshela emsebenzini oqhelile, lezi zinkinga zaxazululwa umlawuli wesistimu, unjiniyela wosekelo lobuchwepheshe, unjiniyela wenethiwekhi, nokunye esikhundleni somsebenzisi. Manje konke kwenziwa ngedwa, yonke into isuka kokuhlangenwe nakho kwami...
Kungani kuphuthuma kangaka?
Okokuqala, ukuze ungalahlekelwa umsebenzi wakho ngenxa yezinkinga zokuxhumana ngezikhathi ezithile. "Imithetho ka-Murphy" edume kabi ayizange ichithwe, futhi ikhefu elilodwa ngesikhathi esingafanele kakhulu lingabiza, uma kungenjalo ukuxoshwa, okungenani ukulahlekelwa umsebenzi.
Okwesibili, iziphazamiso ku-inthanethi zingathinta imali engenayo, ikakhulukazi uma umsebenzi kuwumsebenzi omncane.
Kukhona nezinye izizathu. Isibonelo, ukubuyekeza i-antivirus namanye amathuluzi okuphepha. Isidingo sezinkokhelo eziphuthumayo, isibonelo, isikweletu sikagesi, ukukhokhelwa kwemali mboleko, nokunye.
Uma i-inthanethi ilahlekile isikhathi eside, futhi ifoni yosekelo lwezobuchwepheshe ikhala ngokungapheli: “Uxolo, bonke opharetha bamatasatasa njengamanje...”, sekuyisikhathi sokusebenzisa isiteshi esiyisipele.
Ingabe ngidinga ukuthenga idivayisi ehlukile yalokhu?
Konke kuncike esimweni esithile. Lapha wonke umuntu uyazinqumela.
Okokuqala, udinga ukunaka izinga lakho lemali engenayo kanye nokuthi ufuna ukugcina kangakanani umsebenzi wakho.
Okwesibili, usizo luzofika ngokushesha kangakanani? Isibonelo, uma imodemu kuphela, irutha, noma isiguquli semidiya sihluleka, umhlinzeki uzokunikeza ngokushesha kangakanani inketho yokumiselela? Noma udinga ukuyilungisa ngokwakho, uthenge entsha, uyihlole, uyilungiselele - futhi konke lokhu ngokungabikho kokufinyelela okujwayelekile kwe-inthanethi?
Yini okufanele yenziwe isisebenzi esikude uma i-inthanethi ilahlekile?
Inketho ephephe kunazo zonke akukhona ukulinda kuze kube yilapho kwenzeka inkinga, kodwa ukufaka ngokushesha umugqa ovela kumhlinzeki wesibili ngentengo ethengekayo. Okungcono nakakhulu, sebenzisa "iphromoshini yokuxhumana" futhi ushiye ulayini omdala njengesipele.
Nokho, le sevisi ayitholakali njalo. Kungase kudingeke ulinde kusukela ezinsukwini ezimbalwa... ukuya kokungapheli. Ukuze sifanekise, ake sibheke izibonelo ezimbalwa.
Isibonelo sokuqala - "indlu endala enomhlinzeki omdala"
Ingemuva: Indlu endala yaqashelwa ngokusemthethweni njengesakhiwo somlando. Ngaphambi kwalokhu “kuqashelwa ngokomlando” kwase kunomhlinzeki oyedwa endlini “owayengene” lapho kudala. Ngakho-ke, imishini yafakwa ngesikhathi esifanayo, futhi yonke into yalandela isimiso: "iyasebenza, ungayithinti." Ngokuhamba kwesikhathi, umthwalo esiteshini wanda, futhi izinga lokuxhumana lehla.
Uma sikhuluma ngezakhiwo zomlando, abahlinzeki kufanele baxhumanise ukufakwa kwenethiwekhi enezintambo neziphathimandla zedolobha. Futhi iziphathimandla zedolobha azijahile ukunikeza imvume esekelwe esimisweni esithi: “Uma ukwazi ukungena kuyi-Internet, kwanele lokho.”
Ngakho-ke, umhlinzeki kuphela uphenduke waba yi-monopolist yemvelo, izinhlelo zakhe zingabandakanyi ngandlela-thile ukuxazulula inkinga yekhwalithi yokuxhumana empofu.
Qaphela. Akufanele ucabange ukuthi izinkinga ezinjalo ziphakama kuphela phakathi kwezakhamuzi ezicebile ezihlala enkabeni yeMoscow noma eSt. Kunezizathu ezihlukahlukene zokuthi kungani kungenakwenzeka ukufaka ikhebula lesibili endlini. Ukuba khona kokufinyelela ku-inthanethi okungenantambo kusadala ukuncintisana futhi kubuyisela abahlinzeki esimweni esithuthukisiwe somnotho wemakethe.
Isibonelo sesibili - "ayikho imali, kodwa bambelela!"
Ingemuva: Umhlinzeki kuphela "wezintambo" edolobhaneni lasemaphandleni elakhiwe ngamafulethi amancane.
Ngemva kwesikhathi esithile, ezindlini eziningana ngesikhathi esisodwa isignali kukhebula engenayo yanyamalala ngokuphelele. Izingcingo eziqhubekayo eziya kusekelo lobuchwepheshe azizange ziveze noma yimiphi imiphumela. Ekugcineni, eshayelwa “ukushisa okumhlophe” yizikhalo eziqhubekayo, umlawuli wesistimu womhlinzeki ukhiphe le nkulumo elandelayo: “Iswishi ukuxhumana kwakho okudlule kuyo kushile, abaphathi abaniki imali yokuthenga entsha. eyodwa, ngenxa ye-coronavirus, inkinga yomhlaba wonke, njalonjalo. Zixhume kokuthile ungishiye ngedwa."
Qaphela. Ngaphezu kwalezi zibonelo ezimbili, singakhumbula futhi ukuthi izintambo nemishini yenethiwekhi ngezinye izikhathi zonakaliswa ngesikhathi kulungiswa izindawo zokungena, ukwebiwa okungasho lutho kwemishini yenethiwekhi kwenzeka, nezinye izinto eziningi, lapho bobabili umhlinzeki kanye nabahlali behlupheka.
Ngakho-ke, kuyinto efiselekayo kakhulu ukuba neshaneli eyisipele engenantambo ukuze unganciki “kuzo izimo” ezinjalo.
Ungazilungiselela kanjani izinkinga kusengaphambili?
Ngaphambili esihlokweni Sesibhale kakade ukuthi ukusebenzisa umakhalekhukhwini akuthwali "okuhle" kuphela, kodwa futhi "okubi" okuphawulekayo.
Kalula nje, ukusebenzisa i-smartphone yomuntu siqu ukuze ugcine uxhumano lwe-inthanethi olusebenzayo akuzuzisi kakhulu. Vele, konke kuncike emininingwaneni yendawo kanye nesipho esithile, kepha uma ungazuzanga "izimpahla" ezikhethekile ezivela ku-opharetha weselula futhi ungasebenzisi intela yenkampani emangalisayo ngentengo kanye nomthamo wethrafikhi, khona-ke kungcono. ukubheka ezinye izinketho.
Cishe okuwukuphela kwenzuzo lapho usebenzisa i-smartphone yomuntu siqu njengemodemu eyabiwe ukuthi "awudingi ukuthenga lutho." Kodwa kulokhu, idivayisi yomuntu siqu ingena "ekusetshenzisweni okuvamile" komndeni, okungenzeka kungamjabulisi umnikazi kakhulu. Ngenxa yalokho, kufanele uthenge i-smartphone entsha noma ucingo olucindezela inkinobho “ukushaya izingcingo.”
Ukusabalalisa i-intanethi kusuka ku-smartphone kuya "kumuntu othandekayo" ngandlela-thile kulungile, kodwa emndenini wonke noma ehhovisi elincane lesi sixazululo asifaneleki kakhulu.
Kuyafaneleka futhi ukukhumbula zonke izinhlobo zezimpondo zangaphandle ezikhulisa isignali, okungenakwenzeka ngaso sonke isikhathi ukuzisebenzisa nge-iPhone evamile.
Futhi i-smartphone evamile ngokuqinisekile ngeke ihlale isikhathi eside uma uyilenga kuvulandi noma “esihlahleni esimhlophe se-birch ngaphandle kwefasitela lami” ukuze ubambe isignali ezinzile.
Ulungele ukuthenga idivayisi engenantambo. Yini okufanele uyikhethe?
Uma sidinga ukusungula uxhumano endlini, khona-ke kungaba ukuhlakanipha ukuthenga irutha ye-LTE ethembekile enezimpondo ezinamandla, ezohlinzeka ngesignali eqinile ye-Wi-Fi ngaphakathi endlini kuwo womabili amabhendi: 5Hz kanye ne-2.4Hz. Ngakho-ke, simboza womabili amadivayisi esimanjemanje asekela ukuxhumana kubhendi ye-5Hz, kanye namaklayenti enethiwekhi amadala asekela kuphela ibhendi engu-2.4Hz. Kungenzeka futhi ukuthi amadivayisi atholakala lapho kuphela isignali engu-2.4Hz engangena khona.
Uma sikhuluma ngendlu yezwe, ungase udinge irutha ye-LTE ukuze ubekwe ngaphandle nge-antenna eyakhelwe ngaphakathi enamandla.
Ukusebenzisa irutha ye-LTE njengesisetshenziswa esikhulu sokufinyelela ku-inthanethi
Ezimweni okuxoxwe ngazo ngenhla nomhlinzeki omubi, singancoma ukuxhuma ngesiteshi esingenantambo se-LTE njengesona esiyinhloko, kanye nokusebenzisa umugqa obuthakathaka womhlinzeki wendawo onezintambo (uma ekhona) njengesipele.
Isibonelo, ngaphandle kwedolobha, lapho uxhumano lwezintambo lungalungile, sibamba isignali nge-LTE. Uma ukufinyelela okuvamile “ngocingo” kuvela (isibonelo, ubuyele edolobheni ngemva “kokuzihlukanisa”), inethiwekhi yeselula ingasetshenziswa njengeshaneli eyisipele noma ukukhulula isiteshi esinezintambo ngezikhathi zomthwalo omkhulu.
Phakathi "kwamasosha anjalo" singancoma irutha ye-Cat LTE. 6 endlini -
Umfanekiso 1. Irutha yangaphakathi ye-LTE LTE3301-PLUS.
Izindaba ezinhle ukuthi i-LTE3301-PLUS namanye amamodeli anama-antenna asusekayo azokwamukela izinti zangaphandle kunoma yimuphi umthengisi.
Kusetshenziswa irutha ye-LTE eyengeziwe ekubekeni kwangaphandle
Icala elivamile ukuthi isignali yeselula ngaphakathi endlini ayimukelwa kahle. Kulokhu, kunengqondo ukusebenzisa i-router ye-LTE yangaphandle enamandla e-PoE. Lokhu kungabaluleka ikakhulukazi ezakhiweni ezingaphansi kwedolobha elinesitezi esisodwa, lapho isignali ingafinyeleli kahle. Ezimweni ezinjalo, irutha yangaphandle yegigabit LTE Cat.6 enembobo ye-LAN iyisinqumo esihle
Umfanekiso 2. Irutha yegigabhithi yangaphandle LTE Cat.6 LTE7460-M608.
Manje sikhuluma ngendawo yokuhlala engaphansi kwedolobha, kodwa umsebenzi wasehhovisi nawo udinga ukuxhumana okuthembekile; ezinkampanini ezincane, ukusebenzisa isiteshi sokusekela esisekelwe ku-LTE kuyisixazululo esinengqondo ngokuphelele, ikakhulukazi uma umninikhaya engakuvumeli ukuthi ubhoboze ezindongeni futhi umeme. omunye umhlinzeki.
Ukubhala. Uma ungekho umthombo we-PoE wenethiwekhi: shintsha, i-router, ungasebenzisa i-injector ukuze unikeze amandla nge-PoE, okuthi imodeli ye-LTE7460-M608 isivele ifakiwe kuphakheji yokulethwa.
Imodeli entsha izotholakala ekupheleni kukaMeyi 2020 (irutha ye-LTE Cat.12 yangaphandle i-Zyxel LTE7480-M804 (i-SIM khadi ifakiwe), , nokusekelwa kwe-LTE/3G/2G, amabhendi e-LTE 1/3/7/8/20/38/40, izinti ze-LTE ezinenzuzo engu-8 dBi. Irutha inembobo engu-1 ye-LAN GE enamandla e-PoE. Vele, i-injector ye-PoE nayo ifakiwe.
Umfanekiso 3. Irutha entsha yangaphandle ye-LTE Cat.12 i-Zyxel LTE7480-M804.
Ungasebenzisa umzila wokubekwa kwangaphandle endlini, kodwa okuphambene nalokho - hhayi. Ngakho-ke, amadivaysi anjalo afaneleka nje njengokuthatha indawo yemodemu ye-LTE, kodwa ngokuphuma kwe-Ethernet okungathwalwa ngebanga elingafika ku-100m.
Ungakwazi ukusebenzisa inketho ngerutha ye-LTE kanye nerutha eyengeziwe evela kumhlinzeki "onezintambo". Lolu hlelo lunezinzuzo ezithile - ukuphindaphinda okugcwele, akukho iphuzu elilodwa lokwehluleka. Kuyatuswa futhi ukuthi ucabangele ithonya elilinganayo lamanethiwekhi amabili e-Wi-Fi komunye nomunye; sibhale ngalokhu ngokuningiliziwe ochungechungeni lwezihloko:
Lapho sekufanele unyakaze
Uhlelo olujwayelekile lomsebenzi okude yilapho isisebenzi sichitha isikhathi esiningi singaphandle kwedolobha, kodwa size edolobheni isikhathi esifushane ngokwebhizinisi. Ukuze ungakhokheli ukufinyelela ku-inthanethi ezindaweni ezimbili, ungathenga irutha ye-LTE ephathekayo, edlala indima yokuxhumeka kwe-inthanethi okuyisipele endaweni yakho yaphakade, futhi isebenza njengeyinhloko lapho uya edolobheni.
Ngaphambili thina mayelana nemodeli enhle , kodwa manje umfowabo wesimanje usephumile esekela i-5Hz ne-2.4Hz, futhi iyonke inketho ethuthukisiwe.
Umfanekiso 4. LTE2566-M634 irutha ephathekayo.
Lapho konke sekuhlangene
Ake sicabangele enye inketho yokuhlela umsebenzi, okubuye kube yiselula, nakuba kunzima ukuyibiza ngokuthi idivayisi yomuntu siqu.
Sikhuluma nge-desktop gigabit LTE Cat.6 router AC1200 enembobo ye-LAN ne-Wi-Fi—
Lo modeli uklanyelwe futhi ukhiqizwa ngokuqondile ezimweni lapho udinga ukuhlela ukufinyelela kwabantu abaningana (umndeni, ihhovisi elincane), futhi ngesikhathi esifanayo kunesidingo sokuhamba ngezikhathi ezithile.
Ukubhala. I-Zyxel LTE4506(-M606) LTE-A HomeSpot Router ihlinzeka ngoxhumo lwe-broadband yeselula isebenzisa ubuchwepheshe be-Carrier Aggregation, futhi njengoba lobu buchwepheshe buhambisana ne-LTE, DC-HSPA+/HSPA/UMTS kanye ne-EDGE/GPRS/GSM, iyakwazi ukusebenza nayo amanethiwekhi omakhalekhukhwini emazweni ahlukene. I-LTE4506 ingadlulisela imifudlana emibili yethrafikhi engenantambo ye-AC1200 ngokuhambisana (2.4 Hz kanye no-5 Hz), okukuvumela ukuthi uxhume kumadivayisi asebenzayo afinyelela kwangu-32 ngesikhathi esisodwa nge-Wi-Fi.
Umfanekiso 5. I-Zyxel LTE4506-M606 Umzila Ophathekayo
Imodeli enjalo ingafakwa, isibonelo, kudeskithophu, ekamelweni lomhlangano, ekhishini, ekamelweni lehhotela noma kwenye indawo lapho kulula khona ukuthi usebenze okwamanje.
Umklamo othakazelisayo, izilawuli ezilula kanye nobukhulu obuncane bukuvumela ukuthi ungafihli le divayisi, isibonelo, kukhabhinethi, kodwa ukuyibeka eduze nabahlanganyeli abaqondile ekuhwebeni kwenethiwekhi.
Okunye futhi ukuthi le divayisi, ngenxa yobukhulu bayo futhi azikho izidingo zokubeka, ingakwazi ukuhamba kalula isuka kwenye indawo iye kwenye, igcine ukwamukela kwesignali yeselula ezinzile futhi inikeze ukuxhumana okuzinzile nge-Wi-Fi noxhumo olunezintambo.
Isibonelo, ingafakwa emotweni uma umsebenzi uhamba. Ubukhulu obukhulu (uma kuqhathaniswa ne-LTE2566-M634) kwenze kwaba nokwenzeka ukuthi ungalondolozi ubukhulu be-antenna yangaphakathi nezinye izakhi, okuvumela ikhwalithi yokuxhumana ethuthukisiwe uma kuqhathaniswa nomzila wephaketheni ngalinye.
Esikhundleni se-epilogue
"Ingabe kufanelekile ukubiyela ingadi?", Umfundi ongakholwa uzobuza, "phela, lokhu "kuzihlukanisa" kuzophela ngolunye usuku"...
Iqiniso liwukuthi wona kanye umqondo wokusebenza kude kancane kancane uthola indawo yawo ezimpilweni zethu ngokwandayo. Ngempela, wonke umuntu uyahlangana ukuze "azwe indololwane ye-comrade", kuyilapho nsuku zonke elahlekelwa ngaphezu kwehora lokuphila endleleni eya ehhovisi kanye nenani elifanayo ekhaya, ukudala isiminyaminya sezimoto, ukugijima esitimeleni - kungani konke lokhu?
Ngokushesha noma kamuva, ibhizinisi "lizozama" ngokugcwele umsebenzi oqhelile (ikakhulukazi ukonga ekuqashweni nokugcina indawo eyengeziwe ehhovisi), njengoba nje lizama, isibonelo, imodeli yokuphatha i-matrix. Futhi izosebenzisa indlela entsha yokusebenza.
Ngakho-ke, abasebenzi, lapho bezwa ukunambitheka kwenkululeko lapho besebenza ekhaya, bazolwela le ndlela yokuhlela imisebenzi yomsebenzi.
Linda bese uyabona!
