Kodi chirimwe ndi nthawi yotentha yopezera ntchito kunja?
Nthawi yachilimwe imatengedwa kuti ndi "nyengo yotsika" yochita bizinesi. Anthu ena ali patchuthi, ena samafulumira kugula zinthu zina chifukwa sali m'mikhalidwe yoyenera, ndipo ogulitsa ndi opereka chithandizo amasankha kumasuka panthawiyi.
Chifukwa chake, chilimwe chaogulitsa kunja kapena akatswiri odziyimira pawokha a IT, mwachitsanzo, "oyang'anira dongosolo akubwera," amawonedwa ngati nthawi yosagwira ntchito ...
Koma mukhoza kuyang'ana kumbali inayo. Anthu ambiri amasamukira ku malo atchuthi, ena akufuna kukhazikitsa mauthenga kumalo atsopano, ena akufuna kukhala ndi mwayi wokhazikika kuchokera kulikonse ku Russia (kapena kuchokera kumidzi yapafupi). Kukambirana, kugwirizana ndi ntchito zokonzekera, bungwe lofikira kutali, mwachitsanzo, ku kompyuta yapanyumba, kugwiritsa ntchito mautumiki amtambo - zonsezi zikhoza kufunikira.
Simuyenera kulemba nthawi yomweyo miyezi itatu ya chilimwe ngati yopanda phindu, koma ndi bwino, poyambira, kuyang'ana pozungulira ndikuwona yemwe angafune zomwe m'malo otere. Mwachitsanzo, kulumikizana kudzera pa LTE.
"Wopulumutsa moyo"
Anthu okhala m'mizinda ikuluikulu amawonongeka chifukwa cha kulumikizana kwabwino. Ali ndi njira zambiri zopezera intaneti komanso kudzera pawaya, kuphatikiza chingwe chodzipatulira cha fiber-optic, Wi-Fi yaulere kulikonse komwe kuli kotheka, komanso kulumikizana kodalirika kwa ma cellular kuchokera kwa opanga ma cellular.
Tsoka ilo, mukapita kutali kuchokera kumadera am'madera, mumakhala ndi mwayi wochepa wopeza mauthenga apamwamba. Pansipa tiwona madera omwe kulumikizana kwa LTE kudzathandiza.
Pamene wothandizira akubwerera
Othandizira am'deralo sakhala "panthawi zonse paukadaulo waukadaulo." Nthawi zambiri zimachitika kuti zida za woperekayo, zida zogwirira ntchito komanso ntchito zabwino sizikhala zochititsa chidwi.
Tiyeni tiyambe ndi zomangamanga. Kubweretsa fiber optic GPON ku nyumba iliyonse m'mudzi kapena nyumba iliyonse m'mudzi ndikadali loto.
Othandizira ang'onoang'ono ndi osauka kuposa akuluakulu, azigawo ndi osauka kuposa omwe ali mu likulu, ali ndi zinthu zochepa kuti apange maziko otukuka. Panthawi imodzimodziyo, mphamvu zogula m'midzi yaying'ono ndizochepa kusiyana ndi mizinda ikuluikulu (kupatulapo kawirikawiri). Chifukwa chake, kuyika ndalama "m'mawaya" nthawi zambiri sikukhala ndi chiyembekezo chobweza ndalama.
Nthawi zina, ogwiritsa ntchito amayenera kukhutira ndi kulumikizana kwa ADSL ndi liwiro loyenera ndi kuthekera koyenera. Koma panonso tikukamba za malo okhala ndi zomangamanga zokhazikitsidwa. Midzi yatchuthi yomangidwa kumene, zinthu zakutali monga malo osungiramo zinthu, malo ogulitsa mafakitale nthawi zambiri sakhala ndi mgwirizano uliwonse ndi dziko lakunja, kupatula "ethereal".
Ngati tilankhula za zida, kuthekera kumakhalabe kocheperako. Kuti mugule zida zatsopano zoyankhulirana, muyenera kupeza ndalama zowonjezera. Koma izi sizingatheke nthawi zonse, makamaka chifukwa ndalama zomwe zimafunikira (malingana ndi kutha kwa zombo zamakono) zingakhale zochititsa chidwi kwambiri.
Mfundo ina yofunika ndi mlingo wa utumiki. βKuperewera kwa antchitoβ sizochitika zachilendo. Nthawi zonse pamakhala kusowa kwa akatswiri abwino, ndipo mizinda ikuluikulu kapena "kugwira ntchito kunja" kumapangitsa kuti azitha kupeza malipiro apamwamba kusiyana ndi wothandizira wamba.
Ndikoyenera kutchula udindo wa monopoly pamsika. Ngati pali wopereka intaneti m'modzi yekha m'chigawo chonsecho, sangathe kulamula mitengo yokha, komanso kuchuluka kwa ntchito. Ndiyeno mikangano ya mndandanda: "Kodi iwo (makasitomala) apita kuti kuchokera kwa ife?" kukhala mbiu yaikulu potumikira ogula.
Sitinganene kuti mavuto onsewa anadza chifukwa cha umbombo wa munthu, kusafuna kuchita kalikonse ndi machimo ena a imfa. Ayi konse. Kungoti chuma, luso kapena zinthu zina sizimalola kuthetsa mavuto onse mwamsanga.
Chifukwa chake, njira ina mwanjira yofikira pamlengalenga kudzera pa LTE ndi mwayi wabwino wopititsa patsogolo ntchito zabwino posintha wopereka.
"Tumbleweed"
Pali anthu ambiri omwe udindo wawo, zochita zawo, komanso moyo wawo umalumikizidwa ndi kusuntha pafupipafupi.
Ngati mukuyenda pagalimoto, ndibwino kungoyiwala za njira yolumikizira mawaya. Koma poyenda nthawi zina mumafunika intaneti yapamwamba kwambiri. Mwachitsanzo, kwa womangamanga, womanga, womanga nyumba, katswiri wokonza zida, komanso olemba mabulogi, komanso onse omwe amayenera kulumikizana ndi zida zama network nthawi ndi nthawi pamsewu.
Mungagwiritse ntchito mauthenga a m'manja pa chipangizo chilichonse (ndi kulipira ndalama pa zonsezi), koma n'zosavuta komanso zotsika mtengo kukhala ndi rauta ya LTE m'galimoto ndikugwirizanitsa zipangizo zamakono kudzera pa Wi-Fi.
ndemanga. Kwa anthu omwe amayenda pafupipafupi pagalimoto, titha kupangira zida zonyamulika, monga zonyamula LTE Cat.6 Wi-Fi rauta AC1200 (model WAH7706). Ndi kukula kwawo kochepa, ma routers ang'onoang'ono oterewa amatha kupereka mauthenga odalirika pazida zingapo.
Chithunzi 1. Yonyamula LTE rauta AC1200 (chitsanzo WAH7706).
Kodi sanabweretse intaneti?
Komabe, ngakhale mβmizinda ikuluikulu muli malo amene kupeza Intaneti nβkovuta kapena kulibe. Chitsanzo chabwino ndi zomangamanga. Sizingatheke kukhazikitsa intaneti yamawaya, koma kulumikizana ndikofunikira tsopano, mwachitsanzo, pakuwunika makanema.
Nthawi zina ofesi yogulitsa nyumba zosakhalitsa imagwira ntchito pazinthu zosamalizidwa, zomwe zimafuna mwayi wapamwamba wopita kuzinthu zakutali.
Zofananazi zimachitikanso m'malo opangira mafakitale. Chifukwa cha mtunda wautali komanso ogula ochepa, ndizopanda phindu kuyendetsa chingwe. LTE imathandizira ndi malo ake ambiri.
Ndipo, zowonadi, LTE ikufunika m'midzi yatchuthi. Chikhalidwe cha nyengo yogwiritsira ntchito ntchito, pamene pali anthu ambiri ku dachas m'chilimwe ndipo palibe m'nyengo yozizira, zimapangitsa kuti zinthu izi zikhale zosasangalatsa kwa "opereka mawaya." Chifukwa chake, rauta ya LTE yakhala ikuwoneka ngati "mawonekedwe a dacha" monga ma flip-flops kapena kuthirira m'munda.
Waya wosaduka
Kufikira kudzera pa zingwe zakuthupi kumapereka kulumikizana kokhazikika, kodalirika (pamlingo woyenera waukadaulo), koma kumakhala ndi malire amodzi - chilichonse chimagwira ntchito mpaka chingwe chiwonongeke.
Tengani, mwachitsanzo, njira yowonera makanema. Ngati zithunzi za makamera zimajambulidwa patali kudzera pa intaneti, ndiye kuti ndikofunikira kwambiri kukhala ndi kulumikizana kodziyimira pawokha. Pachifukwa ichi, kupeza mawaya si njira yabwino yothetsera.
Yang'anani pa sitolo, salon ya tsitsi kapena bizinesi ina yaying'ono yomwe ili m'chipinda chapansi choyamba cha nyumba yogonamo. Ngati chingwe chikuwoneka paliponse, ngakhale pang'ono chabe, pamalo ofikirako, mwachitsanzo, kudutsa pamagetsi amagetsi, akhoza kudulidwa ndipo dongosolo loyang'anira kanema lidzasiya kutumiza. Ndipo, ngakhale pali kopi pazinthu zamkati, mwachitsanzo, pa hard drive ya chojambulira, zonsezi: makamera onse ndi chojambulira amatha kuyimitsidwa kapena kutengedwa nanu, kusunga incognito yonse.
Pankhani ya mauthenga opanda zingwe, ndizotheka kusokoneza mwayi wopita ku Network (ngati simuganizira za "jammers") pokhapokha mutalowa m'malo. Ngati mumasamalira magetsi odziyimira pawokha, kwa nthawi yayitali yogwira ntchito, ndiye kuti nthawi zambiri ndizotheka kulemba nthawi yolowera, yomwe imatha kuperekedwa kwa apolisi, kampani ya inshuwaransi, bungwe lachitetezo, ndi zina zotero. .
Chokhumudwitsa china ndi kulephera kwa ma switches ndi zida zina "zogwiritsa ntchito wamba", mwachitsanzo, chifukwa cha zolakwika za omanga opanda luso komanso "amisiri" omwe angathe ndipo amatha kupanga mavuto osiyanasiyana kwa oyandikana nawo.
Pazifukwa zotere, kulumikizana opanda zingwe kudzera pa LTE kungakhale kofunikira.
Kodi mphamvu ya LTE ndi chiyani
Chidule cha LTE chikuyimira Long Term Evolution. M'malo mwake, izi sizirinso muyezo, koma njira yachitukuko yomwe idapangidwa kuti iyankhe funsoli: "Kodi chikukonzekera chiyani pamene kuthekera kwa 3G sikuli kokwanira?" Zinkaganiziridwa kuti LTE idzagwira ntchito mkati mwa 3G, koma pambuyo pake chitukukocho chinakula.
Poyambirira, pazolumikizana zozikidwa paukadaulo wa LTE, zida zopangira maukonde a 3G zitha kugwiritsidwa ntchito pang'ono. Izi zinatithandiza kuti tisunge ndalama zogwiritsira ntchito ndondomeko yatsopanoyi, kuchepetsa mwayi wolowera kwa olembetsa ndikukulitsa kwambiri malo owonetsera.
LTE ili ndi mndandanda wambiri wamakanema pafupipafupi, omwe amatsegula mwayi wogwiritsa ntchito zosiyanasiyana.
Otsatsa amalankhula za LTE ngati m'badwo wachinayi wolumikizana ndi mafoni - "4G". Komabe, ndi bwino kuzindikira kuti pali chisokonezo pang'ono m'mawu omasulira.
Malingana ndi Tekinoloje ya LTE-A idalandira dzina lovomerezeka la IMT-Advanced. Ndipo imanenanso kuti IMT-Advanced, nayonso, imatengedwa ngati ukadaulo wa "4G". Komabe, ITU sichimakana kuti mawu akuti "4G" alibe tanthauzo lomveka bwino ndipo, makamaka, angagwiritsidwe ntchito ku dzina la matekinoloje ena, mwachitsanzo, LTE ndi WiMAX.
Pofuna kupewa chisokonezo, mauthenga ozikidwa pa teknoloji ya LTE-A anayamba kutchedwa "True 4G" kapena "4G yeniyeni", ndipo matembenuzidwe oyambirira amatchedwa "malonda 4G". Ngakhale mayinawa akhoza kuonedwa ngati ochiritsira.
Masiku ano, zida zambiri zotchedwa "LTE" zimatha kugwira ntchito ndi ma protocol osiyanasiyana. Izi zimakhala ndi zotsatira zabwino pakukulitsa malo ofikira (malo ofikira) komanso pama wallet a ogwiritsa ntchito omwe safunikira kugula chipangizo chatsopano nthawi iliyonse.
Foni yam'manja ngati rauta - choyipa chake ndi chiyani?
Kuwerenga za kupezeka kwa ukadaulo wa LTE, nthawi zina pamakhala funso: "N'chifukwa chiyani mugule chipangizo chapadera? Bwanji osagwiritsa ntchito foni yam'manja?" Kupatula apo, mutha "kugawa intaneti kudzera pa Wi-Fi" kuchokera pazida zilizonse zam'manja.
Inde, mungagwiritse ntchito foni yam'manja ngati modemu, koma yankho ili, kuti likhale lofatsa, ndilotsika kwambiri kwa rauta. Pankhani ya rauta yapadera, mutha kusankha njira yoyika panja, ndikuyiyika pamalo olandirira odalirika, mwachitsanzo, pansi pa denga. Njira ina ndikulumikiza mlongoti wapadera. (Kuthandizira kwa tinyanga takunja ndi zitsanzo zenizeni tidzakambirana pansipa).
Kuti mutulutse mwachindunji kuchokera pa foni yam'manja, piritsi kapena laputopu, mwayi woterewu sungatheke.
Chithunzi 2. Outdoor LTE router LTE7460-M608 ndi yoyenera kwa nyumba zazing'ono ndi malo ena akutali.
Mukafunika kulumikiza ogwiritsa ntchito angapo "kugawa kudzera pa foni yam'manja" nthawi yomweyo, zimakhala zovuta kwambiri kugwira ntchito. Mphamvu ya Wi-Fi emitter ya foni yam'manja ndi yofooka kuposa ya rauta yokhala ndi malo olowera. Chifukwa chake, muyenera kukhala pafupi ndi gwero lazizindikiro momwe mungathere. Kuphatikiza apo, batire ya foni yam'manja imatuluka mwachangu kwambiri.
Kuphatikiza pa ma nuances a hardware, palinso ena. Zopereka za Universal zochokera kwa ogwiritsira ntchito ma cellular, opangidwa kuti azigwiritsidwa ntchito pafupipafupi pama foni am'manja ndi intaneti yam'manja, monga lamulo, amakhala ndi malire ndipo sizothandiza makamaka pakugawana nawo maukonde. Ndizosavuta komanso zotsika mtengo kugwiritsa ntchito makontrakitala a pa intaneti pokha. Kuphatikiza ndi chipangizo chapadera, izi zimapereka liwiro labwino pamtengo wopikisana.
Mafunso ena othandiza
Poyamba, tikulimbikitsidwa kuti timvetsetse ntchito zomwe zimafunikira intaneti.
Ngati mukukonzekera "kuthawa chitukuko" ndipo intaneti imangofunika kutsitsa buku lotsatira ku E-book, iyi ndi mtundu umodzi wogwiritsa ntchito.
Ngati mukufuna kukhala olumikizana nthawi zonse, pitilizani kugwira ntchito ndikukhala moyo wokangalika pa intaneti, uwu ndi mtundu wosiyana kwambiri wamasewera komanso katundu wosiyana kwambiri pamaneti.
Zida zamakasitomala zimagwira ntchito yofunikira. Tinene kuti zida zathu za IT ndi laputopu yakale, yotengedwa ngati kuli mvula. Pankhaniyi, ma routers akale komanso amakono ndi oyenera. Chinthu chachikulu ndi chakuti pali chithandizo cha Wi-Fi mumtundu wa 2.4GHz.
Ngati tikukamba za makasitomala mu mawonekedwe a makompyuta, ndiye kuti sangakhale ndi mawonekedwe a Wi-Fi nkomwe. Apa muyenera kusankha mitundu yokhala ndi madoko a LAN kuti mulumikizidwe kudzera pawiri zopotoka.
Pazifukwa zapamwambazi, titha kupangira rauta ya N300 LTE yokhala ndi madoko 4 a LAN (chitsanzo LTE3301-M209). Iyi ndi njira yabwino, yoyesedwa nthawi. Ngakhale Wi-Fi imangothandizidwa pa 802.11 b/g/n (2.4GHz), kukhalapo kwa madoko olumikizira mawaya kumalola kuti igwiritsidwe ntchito ngati chosinthira ofesi yakunyumba kwathunthu. Izi ndizofunikira pakakhala chosindikizira cha netiweki, makompyuta amunthu, NAS yosunga zosunga zobwezeretsera - zambiri, seti yathunthu yamabizinesi ang'onoang'ono.
Router ya LTE3301-M209 imabwera yathunthu ndi tinyanga takunja kuti tilandire ma siginecha kuchokera pamalo oyambira. Kuphatikiza apo, kukhalapo kwa zolumikizira za 2 SMA-F kumakupatsani mwayi wolumikizana ndi tinyanga zamphamvu za LTE zakunja kuti muzitha kulumikizana modalirika ngakhale pomwe ma cell amafooketsa.
Chithunzi 3. LTE Cat.4 Wi-Fi rauta N300 yokhala ndi ma 4 LAN madoko (LTE3301-M209).
Pamene gulu lamagetsi aposachedwa likusamukira ku dacha kapena ofesi yachilimwe: zida zam'manja, ma laputopu apamwamba, ndikwabwino kusankha mitundu yamakono yomwe imathandizira zatsopano zaposachedwa popereka mwayi kudzera pa Wi-Fi, LTE ndi zina zothandiza. zinthu.
Ngati pali mwayi woyika panja, ndikofunikira kuyang'anitsitsa mtundu wa LTE7460-M608. (Onani Chithunzi 2).
Choyamba, kudzakhala kotheka kuyika rauta ya LTE pamalo olandirira bwino, mwachitsanzo, pansi pa denga, kunja kwa nyumba, ndi zina zotero.
Kachiwiri, kuyika kotereku kumathandizira kulumikizana kodalirika kwa Wi-Fi osati mkati mwa nyumbayo, komanso pamalo otseguka. Mtundu wa LTE7460-M608 umagwiritsa ntchito antennas omangidwa ndi phindu la 8 dBi polumikizana. Chinthu chinanso chofunikira ndi chakuti mphamvu ya PoE imakulolani kuti muyike mpaka mamita 100 kuchokera kunyumba kwanu, ndikuyiyika padenga kapena pamtengo. Izi ndizowona makamaka pamene mitengo yayitali ikukula pafupi ndi nyumbayo, yomwe imatha kusokoneza ma siginecha am'manja kuchokera pamalo oyambira. LTE7460-M608 imabwera ndi jekeseni ya PoE yomwe imapereka mphamvu ya PoE + mpaka 30 W.
Koma nthawi zina sizingatheke kugwiritsa ntchito chipangizo chakunja chifukwa cha zochitika zina. Pankhaniyi, rauta ya AC6 gigabit LTE Cat.1200 Wi-Fi yokhala ndi doko la FXS (chitsanzo LTE3316-M604) ithandiza. Chipangizochi chili ndi madoko anayi a GbE RJ-45 LAN. Mfundo yofunika ndi yakuti doko loyamba la LAN1 likhoza kukonzedwanso ngati WAN.
