Esikhathini esithile esidlule ngabhala ukuqhathanisa . Isihloko sivele sidingeka futhi umkhiqizi waseRussia wamadivayisi asebenza kumanethiwekhi e-2G/3G/4G wangithinta. Kwakuthakazelisa kakhulu ukuhlola i-router yaseRussia futhi uyiqhathanise nomnqobi wokuhlolwa kokugcina - i-Zyxel 3316. Ngizosho ngokushesha ukuthi ngizama ngazo zonke izindlela ukusekela umkhiqizi wasekhaya, ikakhulukazi uma engekho ngaphansi izinga kanye nokusebenza kwabaqhudelana nabo kwamanye amazwe. Kodwa nami ngeke ngithule mayelana nokushiyeka. Ngaphezu kwalokho, ngizokwabelana ngolwazi lwami lokuguqula imoto evamile ibe indawo yokufinyelela ku-inthanethi yeselula yekhempu yonke noma ikotishi.
Indaba yomsebenzi oqhelile noma ukuhlala nje ngaphandle kwedolobha ngandlela thize ixhumene nezindaba zobuchwepheshe: ukunikezwa kwamandla okuphuthumayo noma okuzimele, ukuxhumana okuvamile ku-inthanethi. Lokhu kokugcina kubaluleke kakhulu ngenxa yokuthi abaningi babangane bami nabangane bami bakhetha ukusebenza kuma-dachas abo ehlobo, futhi abaningi baye bathuthela ezindlini ezizimele. Ngesikhathi esifanayo, lezo zindlu kuphela ezitholakala ngaphakathi kwemingcele yedolobha zifakwe i-Inthanethi evamile. Kodwa ngokuvamile zixhunywe kuphela nge-fiber optical ruble ayizinkulungwane 15-40. Ngakho okumele ukwenze ukuhlala ku-inthanethi yeselula, ubheke umhlinzeki oshesha kakhulu futhi ongabizi kakhulu emakethe. Kodwa asikhulumi ngokukhetha umhlinzeki, kodwa ngokukhetha i-router. Esivivinyweni sokugcina, i-router iphumelele ngokwethembeka , okubonisa isivinini esiphezulu, zonke ezinye izinto ziyalingana: isikhathi, umhlinzeki, uthi lwangaphandle.
Kulokhu ngizoqhathanisa irutha nomnqobi wangaphambilini kanye nemodemu ekhiqizwa yiMicrodrive. Kube nombono wokumane wengeze izinto ezidlule, kodwa ukungezwa kwaba kukhulu, ngakho nganquma ukuthumela indatshana ehlukile.
Ngakho-ke, ama-routers e-Tandem angamabhodi enziwe eRussia, kodwa anesisekelo sezinto zangaphandle. Yini enye esingayilindela lapho ukukhiqizwa kwethu kwama-radioelements kucekelwe phansi? Kodwa kwasetshenziswa indlela engathi sΓna ngempela. Bheka nje ikesi lensimbi elingasemuva neliqinile - lokhu kuyisixazululo semboni ngaphezu kwe-plastic soap dish-router abantu abaningi abanayo emaphasishi abo. Kuyathakazelisa kakhulu, ngoba izimo zokusebenza zizoba nzima: nginqume ukuthi ngingayivivinyi nje kuphela njenge-router yasekhaya e-attic, eduze kwe-antenna, lapho ingehla khona -35 ebusika kanye nama-degree angu-50 ehlobo, kodwa futhi emotweni, njengendawo yokufinyelela yeselula. Iqiniso liwukuthi kule minyaka engu-10 edlule i-laptop ibihamba nami futhi akunakwenzeka ukubikezela ukuthi umsebenzi uzongithola kuphi.
I-circuitry ilula futhi ithembekile. Umkhiqizi uthi amadivaysi ahlolwe ekamelweni lokushisa emazingeni okushisa ukusuka -40 kuya ku-+60. Ukuze kuqalwe amakhaza ebusika, kukhona ama-thermocouples ashisa ibhodi ngaphambi kokuqala - isicelo esihle sokusebenza ezimweni ezinzima. Irutha nemodemu kubukeka kanje.
Uyini umehluko? Imodemu ye-TANDEM-4G+ isebenza nge-USB futhi yakhelwe ukufaka esikhundleni βamakhwelaβ e-USB aphelelwe yisikhathi asebenza kumasistimu enziwe ngomumo. Inzuzo yayo ukuthi inikeza ukuqiniswa okuthembekile kwemihlangano yekhebula, ngokungafani nama-pigtails, anamathele kakhulu kumamodemu. Ngaphezu kwalokho, ayishisi kakhulu ngaphansi komthwalo osindayo, njengoba kwenzeka ngamamodemu avamile. Hhayi-ke, ubuchwepheshe bokwamukela ukuhlukahluka kwe-MIMO buyasekelwa, okufanele bungeze isivinini.
Irutha ye-Tandem-4GR iyidivayisi ehlukile enembobo ye-Ethernet kanye nemojuli ye-Wi-Fi, lapho udinga ukufaka khona i-SIM khadi ukuze uqale ukusebenza. Isebenzisa umshini onokuguqulwa kwe-Linux, okungukuthi, noma ubani angashintsha amapharamitha futhi alungiselele zonke izici ezitholakala kule *nix system. Ngaphezu kwalokho, i-router isekela amandla ku-voltage ehlukahlukene: kusuka ku-9 kuya ku-36V. Unganikeza la mandla afanayo nge-PoE ngokuxhuma i-adaptha yamandla engu-12 noma engu-24V yangaphandle, kanye nokuxhuma irutha kunethiwekhi yemoto esebhodini. Yingakho ububanzi obunjalo be-voltage busekelwa: lapho injini iqala, i-voltage yehla ibe ngu-9-10V, futhi ngenkathi i-generator isebenza, i-voltage kunethiwekhi ye-on-board ikhuphukela ku-14-15V. Lokhu akusaphathwa ngamaloli inethiwekhi yawo esebhodini yakhelwe i-24V. Okusho ukuthi, lena irutha yezimboni eqinile, ekwazi ukusebenza cishe kunoma yiluphi uhlobo lwamandla ngaphakathi kwebanga elinikeziwe.
Nginentshisekelo kumzila, njengoba uhlelo lolwazi lwasekhaya seluvele lusunguliwe futhi engikudingayo ukufinyelela ku-inthanethi. Ukuxhumeka konke kwehla ekufakeni i-SIM khadi nokuxhuma ikhebula: zonke izilungiselelo zabahlinzeki baseRussia sezivele zifakiwe ku-database, futhi uma kunesidingo, ungakwazi ukulungisa ukucushwa kokuxhumana ngokwakho. Ungaphinda ukhethe noma ulungise ngokuqinile uhlobo lwenethiwekhi ozosebenza nalo. Ngenze lokhu ngicabangela iqiniso lokuthi kimi umsebenzi ubalulekile kumanethiwekhi e-LTE. Bese kuqala ubumnandi - ake sihlole!
Ihlola i-Zyxel LTE3316 vs Tandem-4GR
Indlela yokuhlola ayikashintshi kusukela ekuhlolweni okukhulu kokuqhathanisa kwamarutha: zonke izilinganiso zenziwa nge-SIM khadi eyodwa, emini phakathi nesonto, ukuze kuncishiswe umthelela womthwalo ku-BS. I-antenna isetshenziselwa ukuhlola kusuka ku , efakwe futhi iqondiswe ngqo ku-BS yomsebenzisi. Ukuhlolwa ngakunye kwenziwa izikhathi ezintathu, futhi inani lokugcina latholwa ngokulinganisa imiphumela. Kodwa ukuhlolwa akuzange kuphelele lapho. Nginqume ukuqhathanisa ukuthi ubuchwepheshe be-MIMO kanye nokusetshenziswa kwezinti ezifanayo kuthinta kangakanani izici zesivinini, ngakho nginqamule enye yezintambo kumzila futhi ngaphinda ukuhlolwa.
Imiphumela yokuhlolwa ibimangaza ngokujabulisayo. I-router yaseRussia ayizange ibe yimbi kakhulu kunozakwabo wangaphandle futhi ibonise imiphumela efanayo, isalele ngemuva ngo-2% ngesivinini sokwamukela lapho isebenzisa i-MIMO kanye no-8% lapho isebenza ngothi olulodwa. Kodwa lapho kuthunyelwa idatha, irutha ye-Tandem-4GR yayingaphambi kwe-Zyxel LTE3316 ngo-6%, futhi lapho isebenza ngaphandle kokusekelwa kwe-MIMO yayingemuva ngo-4%. Ngokucabangela amaphutha okulinganisa, lezi zinhlelo zingalinganiswa. Kodwa ngathembisa ukukhuluma ngamaphutha, ake sidlulele kuwo.
Uma i-Zyxel LTE3316 iyirutha eseyenziwe ngomumo ongakwazi ukuxhuma kuyo futhi usebenze, khona-ke i-Tandem-4GR izodinga ukunakwa ngaphambi kokuqala umsebenzi. Ake siqale ngeqiniso lokuthi i-Zyxel inezimbobo ze-4 Ethernet kanye nekhono lokukhuluma usebenzisa i-SIM khadi efakiwe usebenzisa ifoni ye-analog. Ukwengeza, i-Zyxel LTE3316 isekela i-CAT6, okusho ukuthi ukuhlanganisa isixhumanisi kungasetshenziswa ukukhulisa isivinini, kuyilapho i-Tandem-4GR isekela i-CAT4 ngaphandle kokuhlanganisa. Kodwa lo msebenzi usebenza kuphela uma isiteshi esiyisisekelo ngokwaso sisekela ukuhlanganisa. Endabeni yami, i-BS isebenze kumodi ye-CAT4. Futhi, i-Tandem-4GR iziqhayisa ngembobo ye-Ethernet eyodwa kuphela. Okusho ukuthi, ukuxhuma amakhompyutha amaningana uzodinga ukushintshwa. Ngaphezu kwalokho, i-Tandem-4GR ayinawo ama-antenna akhelwe ngaphakathi okuxhumana nabasebenza ngamaselula. Kodwa futhi kunezinzuzo ezibalulekile: i-router ingafakwa e-attic yendlu, ebhokisini lensimbi ku-rack esikhungweni sezitolo, elifakwe emotweni futhi linikezwe amandla kokubili nge-PoE kanye nebhethri eliseduze. Ngaphezu kwalokho, i-router ingasebenza nezicelo ze-USSD, ezokuvumela ukuthi usebenze nge-SIM khadi ngaphandle kokuyikhipha kanye nomzila. Ngakho, kuvela ukuthi umdwebo. Ngakho-ke, ukuhlolwa kuyaqhubeka. Manje sekuyisikhathi sokufaka umzila emotweni futhi uqhubeke nokuhlola.
I-router emotweni. Yini engaba lula?
Ngakho-ke, umqondo wokuhlomisa imoto ngokufinyelela i-inthanethi usunesikhathi eside ukhona. Ekuqaleni, i-intanethi yasakazwa ku-smartphone, ngase ngithola umzila weselula ngebhethri. Kodwa futhi kudinga ukushajwa kabusha, futhi okokukhanyisa ugwayi kungase kuhlale i-smartphone eshajayo noma enye into. Hhayi-ke, bengifuna ukusabalalisa i-Intanethi hhayi kuphela kulabo abasemotweni, kodwa nase-dacha noma ekamu lamatende. Ngesikhathi esifanayo, ngangifuna ukuqeda isidingo sokuthwala uhlobo oluthile "lwe-suitcase yokuxhumana" nami, okungukuthi, lapho imoto ikhona, kufanele kube nokuxhumana. Kulapho irutha ye-Tandem-4GR ehlolwe ngaphezulu yeza khona kahle: ihlangene, ene-adaptha ye-Wi-Fi eyakhelwe ngaphakathi, enekhono lokunikwa amandla phezu kwebanga elibanzi lamandla kagesi. Okulandelayo kuzoba nebhukwana lokufaka i-router emotweni, futhi ekupheleni kokuhlolwa kuzoba nokuqhathanisa ne-smartphone.
Imiyalelo yokufaka irutha ye-Tandem-4GR emotweni ye-Kia Sportage
Ngiyifake emhubheni phakathi kwezihlalo zangaphambili futhi ngaxhuma zonke izintambo lapho, kuhlanganise ne-antenna yangaphandle ye-3G/4G.
Futhi ngiyithathe entweni engasetshenziswanga kubhulokhi ye-fuse. Ngokwemvelo, ngaxhuma yonke into nge-fuse. Ukuxhuma kubhulokhi ye-fuse, ngathatha i-chip eyodwa futhi ngaphula isekethe ngokufinyeza amatheminali ebhethri. Ngabe sengithengisa i-fuse block kwenye yamatheminali.
Okulandelayo, ngibeke inkinobho yokukhanyisa emuva kuphaneli ukuze umzila ungachithi ibhethri ubusuku nemini, kodwa uzovula usebenzisa inkinobho yangaphandle. Inkinobho ngokwayo ifakwe isibani, esidinga amandla. Wajikijela i-minus kumisa eseduze.
Ngabe sengifaka uthi kazibuthe ophahleni . Lolu wuthi oluyisiyingi olunenzuzo engu-3/6 dB futhi lusebenza kububanzi obungu-700-2700 MHz, ukuze irutha ikwazi ukusebenza kuwo wonke amafrikhwensi amanethiwekhi weselula. Kungani kwakudingeka konke lokhu?
Okokuqala, izinga lesiginali enothi lwangaphandle liphakeme kunalapho lamukelwa ngothi lwefoni. Okwesibili, umzimba wensimbi womshini uvikela ngokuqinile isignali, futhi lokhu kubonakala nakakhulu uma uqhubeka usuka embhoshongweni womqhubi weselula. Okwesithathu, umthamo webhethri lemoto uphakeme izikhathi eziningi kunomthamo webhethri yefoni. Futhi, iyashaja ngenkathi ushayela.
Ngakho-ke, ake siqhubekele ezivivinyweni. Ngithole indawo lapho amandla esignali ye-LTE ayemancane ocingweni. Ngehla emotweni, kwazise inkonzo yeSpeedtest ayizange ilayishe nhlobo emotweni, ngathatha izilinganiso.
Ngabe sengiqala irutha futhi ngixhume nge-Wi-Fi kusuka kufoni efanayo kuya kuyo. Kusetshenziswe ama-SIM khadi avela ku-opharetha ofanayo. Okokuqala ngivivinye ngothi lwangaphandle olulodwa. I-Speedtest isivele ibonise imiphumela eyamukelekayo yokuphenya iwebhu.
Ekugcineni, ngixhume i-antenna yangaphandle yesibili kumzila ukuze ngihlole ukuthi ubuchwepheshe be-MIMO bube nomthelela ngempela ngesignali ebuthakathaka kangaka. Ngokumangalisayo, izinga lokwamukelwa likhuphuke izikhathi ezingaphezu kwesisodwa nesigamu. Nakuba ijubane lokudlulisa lihlala lifana. Lokhu kungenxa yezici zobuchwepheshe be-MIMO, okuhloswe ngazo ukuthuthukisa izici zesiginali engenayo.
isiphetho
Sekuyisikhathi sokukufingqa. Irutha ye-Tandem-4GR kanye nemodemu ye-TANDEM-4G+ zinemojuli yerediyo ebucayi ekuvumela ukuthi uthole isivinini esihle ngezinga lesignali elibi - lokho kuyiqiniso. Mayelana nokusebenza, irutha ye-Tandem-4GR ingaqhudelana kalula nowinile ezivivinyweni zangaphambilini, i-Zyxel 3316, kanye nemodemu ye-TANDEM-4G+ ingangena esikhundleni sanoma iyiphi imodemu ye-USB engqalasizinda ekhona ngothi kanye nerutha/ikhompyutha evamile ekhona. Umehluko wamanani phakathi kwe-Tandem-4GR ne-Zyxel 3316 cishe ama-ruble angu-500 ngokuvuna owokuqala, okwanele ukuthenga ukushintshwa kwe-gigabit. Kodwa idivayisi ye-Tandem-4GR ayinawo ama-antenna akhelwe ngaphakathi, kodwa i-Zyxel 3316 ayikwazi ukunikwa amandla kalula kunethiwekhi yemoto, futhi ithatha isikhala esiningi ngokuphawulekayo.
Ngenxa yalokho, ngiyakwazi ukubona uchungechunge lwe-Tandem njengolukhiqizayo futhi olufanele ukubekwa kokubili njengomthombo we-inthanethi wendlu yezwe, nanjengomzila wamaphoyinti akhethekile noma izinto ezihambayo.
