Ke\u010f som za\u010dal h\u013eada\u0165 rie\u0161enia na zlep\u0161enie r\u00fdchlosti internetu, komunikoval som s mnoh\u00fdmi odborn\u00edkmi. V\u00fdsledkom bol kr\u00e1tky zoznam vec\u00ed, na ktor\u00e9 by sa ur\u010dite malo zamera\u0165:<\/p>\n

0. Spomen\u00fa\u0165 si na \u0161kolsk\u00fa fyziku o vln\u00e1ch a riadi\u0165 sa logikou
\n1. Predt\u00fdm, ne\u017e \u010doko\u013evek odhadne\u0161 a zosiln\u00ed\u0161, je potrebn\u00e9 zmera\u0165 r\u00fdchlos\u0165 internetu skoro r\u00e1no, cez de\u0148, v \u0161pi\u010dke ve\u010der (okolo 20. hodiny), neskoro v noci. Ak s\u00fa kol\u00edsania v\u00e4\u010d\u0161ie ako 30 % \u2013 znamen\u00e1 to, \u017ee je pre\u0165a\u017een\u00e1 z\u00e1kladn\u00e1 stanica. Opravi\u0165 to m\u00f4\u017ee len h\u013eadanie menej pre\u0165a\u017eenej BS. A ani vtedy to nie je ist\u00e9.
\n2. D\u00f4kladne zv\u00e1\u017ei\u0165 mo\u017en\u00e9 rie\u0161enia \u2013 klady a z\u00e1pory z\u00e1sadn\u00e9
\n3. Nebu\u010fte lakom\u00ed. \u00c1no, po\u010diato\u010dn\u00e9 n\u00e1klady sa zdaj\u00fa by\u0165 extr\u00e9mne vysok\u00e9. Tu prich\u00e1dza do \u00favahy princ\u00edp \u201enevyhnutn\u00e9 a dostato\u010dn\u00e9\u201c
\n4. Nezviazujte sa na uzamknut\u00e9 zariadenia. Programy m\u00f4\u017eu by\u0165 zle nap\u00edsan\u00e9, in\u00fd oper\u00e1tor m\u00f4\u017ee za\u010da\u0165 fungova\u0165 lep\u0161ie ako vybran\u00fd. Preto iba origin\u00e1ly alebo odblokovan\u00e9 + jednozna\u010dne origin\u00e1lny softv\u00e9r
\n5. D\u00f4kladnos\u0165. Stoj\u00ed za to skontrolova\u0165 v\u0161etk\u00fdch oper\u00e1torov \u2013 jeden z nich m\u00f4\u017ee \u010dasto prinies\u0165 prekvapenie (boli pr\u00edpady, ke\u010f Megafon a MTS boli \u00faplne za\u0165a\u017een\u00e9, zatia\u013e \u010do Beeline pokojne d\u00e1val viac ako 15+ Mbit na s\u0165ahovanie\/odosielanie).
\n6. Trpezlivos\u0165. In\u0161tal\u00e1cia syst\u00e9mu nie je z\u00e1le\u017eitos\u0165ou p\u00e1r min\u00fat, najm\u00e4 ak to nerob\u00edte ka\u017ed\u00fd de\u0148. Ka\u017ed\u00fd stupe\u0148, ka\u017ed\u00fd centimeter vy\u0161\u0161ie\/ni\u017e\u0161ie \u2013 m\u00f4\u017ee sp\u00f4sobi\u0165 rozdiely o nieko\u013eko megabitov. Sk\u00fasen\u00ed technici d\u00f4kladne dr\u017eia ant\u00e9nu, ke\u010f utiahnu upevnenia \u2013 inak sa m\u00f4\u017ee trochu zmeni\u0165 smerovanie, \u010do negat\u00edvne ovplyvn\u00ed r\u00fdchlos\u0165.
\n7. Ak je to mo\u017en\u00e9, zverte to odborn\u00edkom \u2013 je lep\u0161ie d\u00f4verova\u0165 odborn\u00edkom. M\u00f4\u017eete narazi\u0165 na probl\u00e9my pri zostavovan\u00ed kompatibility zariadenia (softv\u00e9rovo, po nap\u00e1jan\u00ed, po konektoroch at\u010f.), m\u00f4\u017eete sa m\u00fdli\u0165 pri lisovan\u00ed k\u00e1bla, v\u00fdbere pigtailov pre modem a nastavovan\u00ed ant\u00e9ny.
\n8. \u010cas. Od a do m\u00f4\u017ee trva\u0165 od jedn\u00e9ho d\u0148a do t\u00fd\u017ed\u0148a<\/p>\n

Po naplnen\u00ed te\u00f3riou som pre\u0161iel k praxi. Podmienky s\u00fa tak\u00e9: najbli\u017e\u0161ia ve\u017ea s podporou LTE je priamo vo vzdialenosti 3-4 km, ale na ceste sign\u00e1lu stoja stromy. A ak v zime nepr\u00edtomnos\u0165 listov pozit\u00edvne ovplyv\u0148uje sign\u00e1l, v lete kvalita sign\u00e1lu v\u00fdrazne kles\u00e1 a zatia\u013e sa mi v\u00f4bec nechce zdv\u00edha\u0165 sto\u017eiar s ant\u00e9nou a zaobera\u0165 sa ochrann\u00fdm syst\u00e9mom proti blesku. Na ceste sign\u00e1lu nie s\u00fa \u017eiadne \u010fal\u0161ie prek\u00e1\u017eky okrem stromov. Lesn\u00fd p\u00e1s je kr\u00e1tky, pribli\u017ene 100 metrov.<\/p>\n

Druh\u00fdm krokom bola samostatn\u00e1 mont\u00e1\u017e podobn\u00e9ho setu na b\u00e1ze Zyxel Keenetic LTE. Je to jedin\u00fd Keenetic v s\u00e9rii, ktor\u00fd m\u00e1 zabudovan\u00fd 4G modem, v\u0161etky ostatn\u00e9 vy\u017eaduj\u00fa pripojenie extern\u00e9ho USB modemu. Zdrojem pr\u00edstupu na internet m\u00f4\u017ee by\u0165 aj sie\u0165ov\u00fd poskytovate\u013e, ktor\u00fd poskytuje pripojenie cez Ethernet alebo Wi-Fi. V mojom pr\u00edpade pou\u017e\u00edvam len pr\u00edstup na internet cez LTE, tak\u017ee vlo\u017e\u00edme SIM kartu do pr\u00edslu\u0161n\u00e9ho slotu a zapneme router. V norm\u00e1lnom pr\u00edpade, kde je pokrytie siete dobr\u00e9, sa \u00farove\u0148 sign\u00e1lu zobraz\u00ed na prednom paneli a pr\u00edstup do siete sa zobraz\u00ed ihne\u010f alebo po kr\u00e1tkom nastaven\u00ed cez webov\u00e9 rozhranie. V mojom pr\u00edpade je sila sign\u00e1lu pr\u00edli\u0161 slab\u00e1, tak\u017ee bolo potrebn\u00e9 pou\u017ei\u0165 extern\u00fa ant\u00e9nu. Na zadnej strane routera je nieko\u013eko konektorov na pripojenie MIMO ant\u00e9ny a prep\u00edna\u010d medzi vn\u00fatornou a vonkaj\u0161ou ant\u00e9nou. Po pripojen\u00ed ant\u00e9ny 3G\/4G OMEGA MIMO<\/a><\/noindex>, som z\u00edskal sign\u00e1l aj na zna\u010dnej vzdialenosti od z\u00e1kladne a cez prek\u00e1\u017eku v podobe lesn\u00e9ho p\u00e1su. Ale treba ma\u0165 na pam\u00e4ti, \u017ee v pr\u00edpade tohto spojenia je potrebn\u00e9 umiestni\u0165 router \u010do najbli\u017e\u0161ie k ant\u00e9ne, preto\u017ee aj v najlep\u0161om k\u00e1ble d\u00f4jde k \u00fatlmu, a teda r\u00fdchlos\u0165 bude ni\u017e\u0161ia. Toto je hlavn\u00fd rozdiel medzi Zyxel LTE 6101 a Zyxel Keenetic LTE + extern\u00e1 ant\u00e9na.
\nAj ja som sa neubr\u00e1nil a otvoril som Zyxel Keenetic LTE na kontrolu. Fotografie pod \u010dl\u00e1nkom.<\/p>\n

Polariz\u00e1cia<\/b>
\nAk sa pozriete na fotografiu rozobran\u00e9ho vonkaj\u0161ieho bloku od Zyxel LTE 6101, m\u00f4\u017eete si v\u0161imn\u00fa\u0165, ako je ant\u00e9na oto\u010den\u00e1 o 45 stup\u0148ov od tela. Aby ste dosiahli dobr\u00fa \u00farove\u0148 sign\u00e1lu a maxim\u00e1lnu r\u00fdchlos\u0165, je potrebn\u00e9, aby polariz\u00e1cia prij\u00edmacej ant\u00e9ny zodpovedala polariz\u00e1cii ant\u00e9ny BS. Na samotnej ant\u00e9ne je ur\u010dite vyzna\u010den\u00e1 \u0161\u00edpka smerom polariz\u00e1cie. Napr\u00edklad, r\u00fdchlos\u0165 spojenia u m\u0148a vzr\u00e1stla o tretinu, ke\u010f som oto\u010dil ant\u00e9nu o 45 stup\u0148ov. Vopred to predpoveda\u0165 je \u0165a\u017ek\u00e9, preto je pri mont\u00e1\u017ei potrebn\u00e9 zoh\u013eadni\u0165 tento fakt a vysk\u00fa\u0161a\u0165 r\u00f4zne mo\u017enosti in\u0161tal\u00e1cie.<\/p>\n

A teraz bude \u00faplne logick\u00e9 porovna\u0165 tri sety za 7290, 11200 a 25000 kor\u00fan.<\/p>\n

\nZhrnutie<\/b>
\nAko je vidno na sn\u00edmke, najr\u00fdchlej\u0161ou vo\u013ebou je Zyxel LTE 6101. Na tom sa podpisuje umiestnenie modemu bl\u00edzko ant\u00e9ny a minim\u00e1lna d\u013a\u017eka k\u00e1blov medzi nimi. Zariadenie je zauj\u00edmav\u00e9, funk\u010dn\u00e9, ale nie cenovo dostupn\u00e9. Je vhodn\u00e9 pre t\u00fdch, ktor\u00ed s\u00fa ochotn\u00ed plati\u0165 za stabiln\u00e9 a spo\u013eahliv\u00e9 pripojenie.
\nDruh\u00e9 miesto patr\u00ed Zyxel Keenetic LTE s externou ant\u00e9nou. T\u00e1to kombin\u00e1cia je ur\u010dite ve\u013emi kvalitn\u00e1 a r\u00fdchlos\u0165 prij\u00edmania a odosielania sa bl\u00ed\u017ei k Zyxel LTE 6101. Preto pre t\u00fdch, ktor\u00ed nepotrebuj\u00fa maxim\u00e1lnu r\u00fdchlos\u0165 a s\u00fa ochotn\u00ed investova\u0165 \u010das do kladenia k\u00e1blov a vyla\u010fovania ant\u00e9ny (\u010do sa bude musie\u0165 robi\u0165 aj s Zyxel LTE 6101), bude tento set v\u00fdrazne lacnej\u0161\u00ed a funk\u010dne bohat\u0161\u00ed. Napr\u00edklad aj preto, \u017ee Zyxel Keenetic LTE m\u00e1 vstavan\u00fd adapt\u00e9r pre SIP telef\u00f3niu a 5 gigabitov\u00fdch portov.
\nPosledn\u00e1 s\u00faprava (LTE MiMo INDOOR+Huawei E5372) m\u00e1 z\u00e1sadn\u00fa nev\u00fdhodu kv\u00f4li absencii Ethernet portov. Okrem toho, za s\u00fa\u010dasn\u00fdch podmienok, ke\u010f listy zakr\u00fdvaj\u00fa cestu sign\u00e1lu, 4G nebolo zachyten\u00e9 ani s externou ant\u00e9nou, ale 3G pripojenie bolo celkom uspokojiv\u00e9. Pravda, latencie s\u00fa pomerne zna\u010dn\u00e9 a telefonova\u0165 cez VoIP nie je ve\u013emi pohodln\u00e9. Tento typ pripojenia je vhodn\u00fd pre t\u00fdch, ktor\u00ed potrebuj\u00fa internet len na surfovanie.<\/p>\n
