Nthawi ina kale ndinalemba kufananiza . Mutuwu udakhala wofunikira ndipo wopanga zida zaku Russia zogwirira ntchito mumanetiweki a 2G/3G/4G adandilumikizana nane. Zinali zosangalatsa kwambiri kuyesa rauta ya ku Russia ndikuyifananitsa ndi wopambana mayeso omaliza - Zyxel 3316. Ndidzanena nthawi yomweyo kuti ndimayesetsa m'njira zonse kuthandizira wopanga pakhomo, makamaka ngati sali wotsika pansi. khalidwe ndi magwiridwe antchito akunja mpikisano. Koma sindikhala chete pazophophonyazo. Kuphatikiza apo, ndigawana zomwe ndakumana nazo pakusandutsa galimoto wamba kukhala malo ofikira pa intaneti pa msasa wonse kapena kanyumba.
Nkhani yogwira ntchito zakutali kapena kungokhala kunja kwa mzindawo ndi njira imodzi yolumikizidwa ndi zovuta zaukadaulo: magetsi odzidzimutsa kapena odziyimira pawokha, kulumikizana kwabwino pa intaneti. Chotsatirachi ndi chofunikira kwambiri chifukwa chakuti anzanga ambiri ndi anzanga amasankha kugwira ntchito m'ma dachas m'chilimwe, ndipo ambiri asamukira kukakhala m'nyumba zaumwini. Nthawi yomweyo, nyumba zokhazo zomwe zili mkati mwa malire amzindawu zili ndi intaneti yabwinobwino. Koma nthawi zambiri amalumikizidwa kokha kudzera mu fiber kuwala kwa 15-40 zikwi rubles. Chifukwa chake zomwe muyenera kuchita ndikukhala pa intaneti yam'manja, kuyang'ana wopereka mwachangu komanso wotsika mtengo kwambiri pamsika. Koma sitikunena za kusankha wothandizira, koma kusankha rauta. Pakuyesa komaliza, rautayo adapambana moona mtima , kusonyeza kuthamanga kwakukulu, zinthu zina zonse kukhala zofanana: nthawi, wopereka, mlongoti wakunja.
Nthawi ino ndifananiza rauta ndi wopambana wakale ndi modem yopangidwa ndi Microdrive. Panali lingaliro longowonjezera zomwe zapita, koma zowonjezerazo zidakhala zazikulu, kotero ndidaganiza zotumiza nkhani ina.
Chifukwa chake, ma tandem ma routers ndi matabwa opangidwa ndi Russia, koma okhala ndi zinthu zakunja. Ndi chiyani chinanso chomwe tingayembekezere pamene kupanga kwathu kwa ma radioelements kwawonongeka? Koma njira yozama kwenikweni idagwiritsidwa ntchito. Tangoyang'anani pazitsulo zolimba komanso zamphamvu - iyi ndi njira yothetsera mafakitale kusiyana ndi mbale ya sopo ya pulasitiki yomwe anthu ambiri ali nayo m'misewu yawo. Ndizosangalatsa kwambiri, chifukwa machitidwe opangira opaleshoni adzakhala ovuta: ndinaganiza kuti ndisayese ngati rauta yapanyumba mu chipinda chapamwamba, pafupi ndi mlongoti, kumene imatha kufika -35 m'nyengo yozizira ndi madigiri 50 m'chilimwe, komanso m'galimoto, ngati malo ofikira mafoni. Zoona zake n'zakuti kwa zaka 10 laputopu wakhala akuyenda ndi ine ndipo n'zosatheka kulosera kumene ntchito adzandipeza.
Zozungulira ndizosavuta komanso zodalirika. Wopangayo akunena kuti zidazo zinayesedwa m'chipinda chotentha kutentha kuchokera -40 mpaka +60. Kuzizira kumayamba, pali ma thermocouples omwe amawotcha bolodi asanayambe - ntchito yabwino yogwirira ntchito muzovuta. Router ndi modem zimawoneka chonchi.
Kodi pali kusiyana kotani? Modem ya TANDEM-4G + imagwira ntchito kudzera pa USB ndipo idapangidwa kuti ilowe m'malo mwa "mluzu" wakale wa USB womwe umagwira ntchito m'makina opangidwa okonzeka. Ubwino wake ndikuti umapereka kukhazikika kodalirika kwa misonkhano ya chingwe, mosiyana ndi ma pigtails, omwe amakhala ofooka kwambiri pama modemu. Komanso, si overheat pansi katundu wolemera, monga zimachitika ndi modemu ochiritsira. Chabwino, ukadaulo wa MIMO wolandila zosiyanasiyana umathandizidwa, womwe uyenera kuwonjezera liwiro.
Tandem-4GR rauta ndi chipangizo chosiyana chokhala ndi doko la Efaneti ndi gawo la Wi-Fi, momwe mumangofunika kuyika SIM khadi kuti muyambe kugwira ntchito. Imayendetsa makina osinthika a Linux, ndiye kuti, aliyense akhoza kusintha magawo ndikusintha zonse zomwe zili mu * nix system. Kuphatikiza apo, rauta imathandizira mphamvu pamagetsi osiyanasiyana: kuyambira 9 mpaka 36V. Mungathe kupereka mphamvu zomwezo kudzera mu PoE mwa kulumikiza adaputala yakunja ya 12 kapena 24V yamagetsi, komanso kulumikiza rauta ku netiweki yapagalimoto. Ichi ndichifukwa chake mitundu yosiyanasiyana yamagetsi imathandizidwa: injini ikayamba, voteji imatsikira ku 9-10V, ndipo pamene jenereta ikugwira ntchito, voteji pa intaneti imakwera mpaka 14-15V. Izi sizikutanthauza magalimoto omwe maukonde awo pa board adapangidwira 24V. Ndiko kuti, iyi ndi rauta yamphamvu kwambiri yamafakitale, yomwe imatha kugwira ntchito pafupifupi mtundu uliwonse wamagetsi mkati mwamtundu womwe wapatsidwa.
Ndili ndi chidwi ndi rauta, popeza dongosolo lazidziwitso zakomweko kunyumba lakhazikitsidwa kale ndipo zomwe ndikufunika ndi intaneti. Kulumikizana konse kumatsikira pakuyika SIM khadi ndikulumikiza chingwe: zoikamo zonse za opereka aku Russia zaphatikizidwa kale m'dawunilodi, ndipo ngati kuli kofunikira, mutha kusintha makonzedwe olumikizira nokha. Mukhozanso kusankha kapena kukonza mosasunthika mtundu wa netiweki kuti mugwiritse ntchito. Ndidachita izi poganizira kuti kwa ine ntchito ndiyofunikira kwambiri pamanetiweki a LTE. Ndiyeno zosangalatsa zimayamba - tiyeni tiyese!
Kuyesa Zyxel LTE3316 vs Tandem-4GR
Njira yoyesera sinasinthe kuyambira pakuyesa kwakukulu kofananira kwa ma routers: miyeso yonse imachitika ndi SIM khadi imodzi, masana pasanathe sabata, kuti muchepetse kukhudzika kwa katundu pa BS. Mlongoti umagwiritsidwa ntchito poyesa kuchokera , yomwe imakwezedwa ndikulunjika mwachindunji ku BS ya wogwiritsa ntchito. Chiyeso chilichonse chinachitidwa katatu, ndipo mtengo womaliza unapezedwa mwa kuwerengera zotsatira. Koma mayesowo sanathere pamenepo. Ndinaganiza zofananiza kuchuluka kwa teknoloji ya MIMO ndi kugwiritsa ntchito ma antennas ofanana ndi momwe zimakhudzira maonekedwe a liwiro, kotero ndinadula chingwe chimodzi kuchokera pa router ndikubwereza mayesero.
Zotsatira za mayeso zinali zodabwitsa. Router ya ku Russia sinali yoyipa kwambiri kuposa mnzake wakunja ndipo idawonetsa zotsatira zofananira, kutsalira ndi 2% pa liwiro lolandila mukamagwiritsa ntchito MIMO ndi 8% pogwira ntchito ndi mlongoti umodzi. Koma potumiza deta, rauta ya Tandem-4GR inali patsogolo pa Zyxel LTE3316 ndi 6%, ndipo pogwira ntchito popanda thandizo la MIMO inali kumbuyo ndi 4%. Poganizira zolakwika za muyeso, machitidwewa akhoza kusinthidwa. Koma ndinalonjeza kuti ndilankhula za zophophonyazo, choncho tiyeni tipitirire kwa iwo.
Ngati Zyxel LTE3316 ndi rauta yokonzekera yomwe mungalumikizane nayo ndikugwira ntchito, ndiye kuti Tandem-4GR idzafunika chidwi musanayambe ntchito. Tiyeni tiyambe ndi mfundo yakuti Zyxel ali 4 Efaneti madoko ndi luso kulankhula ntchito anaika SIM khadi ntchito analogi foni. Kuphatikiza apo, Zyxel LTE3316 imathandizira CAT6, zomwe zikutanthauza kuti kuphatikiza ulalo kungagwiritsidwe ntchito kukulitsa liwiro, pomwe Tandem-4GR imathandizira CAT4 popanda kuphatikiza. Koma izi zimangogwira ntchito ngati base station palokha imathandizira kuphatikizika. Kwa ine, BS inagwira ntchito mu CAT4 mode. Komanso, Tandem-4GR imangodzikuza ndi doko limodzi la Ethernet. Ndiye kuti, kulumikiza makompyuta angapo mudzafunika kusintha. Kuphatikiza apo, Tandem-4GR ilibe tinyanga zomangira zolumikizirana ndi ogwiritsa ntchito ma cellular. Koma palinso ubwino waukulu: rauta ikhoza kuikidwa m'chipinda chapamwamba cha nyumba, mu bokosi lachitsulo pazitsulo pamalo ogulitsira, okwera m'galimoto ndipo amaperekedwa ndi mphamvu zonse kudzera pa PoE komanso kuchokera ku batri yapafupi. Kuphatikiza apo, rauta imatha kugwira ntchito ndi zopempha za USSD, zomwe zingakuthandizeni kugwira ntchito ndi SIM khadi popanda kuichotsa ndi rauta. Chifukwa chake, zimakhala zokopa. Choncho, mayesero akupitirira. Tsopano ndi nthawi yoti muyike rauta m'galimoto ndikupitiliza kuyesa.
Router m'galimoto. Ndi chiyani chomwe chingakhale chophweka?
Chifukwa chake, lingaliro lokonzekeretsa galimoto yokhala ndi intaneti lakhalapo kwa nthawi yayitali. Poyamba, intaneti idagawidwa kuchokera ku foni yamakono, kenako ndinapeza rauta yam'manja yokhala ndi batire. Koma imafunikanso kuyitanitsa, ndipo choyatsira ndudu chikhoza kukhala ndi foni yamakono yolipira kapena china. Chabwino, ndinkafuna kugawira intaneti osati kwa omwe ali m'galimoto, komanso ku dacha kapena kumsasa wa mahema. Panthawi imodzimodziyo, ndinkafuna kuchotsa kufunikira konyamula mtundu wina wa "sutikesi yolankhulana" ndi ine, ndiko kuti, kumene galimoto ili, payenera kukhala kugwirizana. Apa ndipamene rauta ya Tandem-4GR yoyesedwa pamwambapa idabwera yothandiza: yaying'ono, yokhala ndi adaputala ya Wi-Fi yomangidwira, yotha kuyendetsedwa ndi ma voltage osiyanasiyana. Kenako padzakhala buku la kukhazikitsa rauta m'galimoto, ndipo kumapeto kwa mayeso padzakhala kufananitsa ndi foni yamakono.
Malangizo oyika rauta ya Tandem-4GR mugalimoto ya Kia Sportage
Ndinayiyika mumsewu pakati pa mipando yakutsogolo ndikulumikiza mawaya onse pamenepo, kuphatikiza mlongoti wakunja wa 3G/4G.
Kuphatikiza apo ndidazitenga kuchokera ku chinthu chosagwiritsidwa ntchito mu block ya fuse. Mwachibadwa, ndinagwirizanitsa chirichonse kupyolera mu fusesi. Kuti ndilumikizane ndi chipika cha fuse, ndinatenga chip chimodzi ndikuphwanya dera pofupikitsa ma terminals ku batri. Kenako ndinagulitsa chipika chakutali ku malo ena.
Kenako, ndinayika batani lowunikiranso pagawo kuti rauta isakhetse batire nthawi yonseyi, koma ndiyatse pogwiritsa ntchito batani lakunja. Bulu lokhalo lili ndi babu, lomwe limafuna mphamvu. Anaponya minus pa misa yapafupi.
Kenako ndinaika mlongoti wa maginito padenga . Ichi ndi mlongoti wozungulira wokhala ndi phindu la 3/6 dB ndipo umagwira ntchito pafupipafupi 700-2700 MHz, kotero rauta imatha kugwira ntchito pafupipafupi pama foni am'manja. Nβchifukwa chiyani zonsezi zinali zofunika?
Choyamba, mulingo wa siginecha wokhala ndi mlongoti wakunja ndi wapamwamba kuposa momwe ulandilidwa ndi mlongoti wafoni. Kachiwiri, thupi lachitsulo la makinawo limateteza kwambiri chizindikirocho, ndipo izi zimawonekera kwambiri mukamachoka pansanja ya oyendetsa ma cell. Chachitatu, mphamvu ya batire yagalimoto ndiyokwera nthawi zambiri kuposa kuchuluka kwa batire la foni. Kuphatikiza apo, imalipira mukamayendetsa.
Choncho, tiyeni tipite ku mayesero. Ndinapeza malo omwe mphamvu ya chizindikiro cha LTE inali yochepa pa foni. Ndinatuluka mgalimoto muja, popeza ntchito ya Speedtest sinalowe mgalimoto muja, ndikuyesa.
Kenako ndinayamba rauta ndikulumikiza kudzera pa Wi-Fi kuchokera pafoni yomweyo kupita nayo. Ma SIM khadi ochokera kwa woyendetsa yemweyo adagwiritsidwa ntchito. Poyamba ndinayesa ndi mlongoti wakunja wakunja. Speedtest yawonetsa kale zotsatira zovomerezeka pakufufuza pa intaneti.
Pomaliza, ndinalumikiza mlongoti wachiwiri wakunja ku rauta kuti ndiwone ngati ukadaulo wa MIMO uli ndi zotsatirapo ndi chizindikiro chofooka chotere. Chodabwitsa n'chakuti chiwerengero chovomerezeka chinawonjezeka ndi nthawi imodzi ndi theka. Ngakhale liwiro lotengerako limakhalabe lomwelo. Izi ndichifukwa cha mawonekedwe aukadaulo a MIMO, omwe cholinga chake ndi kukonza mawonekedwe a chizindikiro chomwe chikubwera.
Pomaliza
Yakwana nthawi yoti mufotokoze mwachidule. Routa ya Tandem-4GR ndi modemu ya TANDEM-4G + ili ndi gawo lomvera pawailesi lomwe limakulolani kuti muzitha kuthamanga bwino ndi siginecha yoyipa - izi ndi zoona. Pankhani ya magwiridwe antchito, rauta ya Tandem-4GR imatha kupikisana mosavuta ndi wopambana mayeso am'mbuyomu, Zyxel 3316, ndi modemu ya TANDEM-4G + imatha kulowa m'malo mwa modemu iliyonse ya USB muzomangamanga zomwe zilipo ndi mlongoti ndi rauta / kompyuta wamba yomwe ilipo. Kusiyana kwamtengo pakati pa Tandem-4GR ndi Zyxel 3316 ndi pafupifupi 500 rubles mokomera woyamba, zomwe ndi zokwanira kugula gigabit lophimba. Koma chipangizo cha Tandem-4GR sichikhala ndi tinyanga zomangidwa, koma Zyxel 3316 sichikhoza kuyendetsedwa mosavuta kuchokera pa intaneti ya galimoto, ndipo imatenga malo ochulukirapo.
Zotsatira zake, ndimatha kuzindikira mndandanda wa Tandem ngati wothandiza komanso woyenera kukhazikitsidwa ngati gwero la intaneti la nyumba yakumudzi, komanso ngati rauta ya mfundo zapadera kapena zinthu zosuntha.
