Za\u010dnime s frekvenciou: LTE v Rusku funguje na frekvenci\u00e1ch 450, 800, 900, 1800, 1900, 2100, 2300, 2500 a 2600 MHz. Ak si spomenieme na fyziku, tam sa jasne vysvet\u013eovalo, \u017ee ni\u017e\u0161ie frekvencie maj\u00fa lep\u0161iu prenikav\u00fa schopnos\u0165 a silnej\u0161ie sa tlmia na v\u00e4\u010d\u0161\u00edch vzdialenostiach.

Napr\u00edklad, ve\u017ea pren\u00e1\u0161a d\u00e1ta na frekvenci\u00e1ch 1800 a 2600 MHz. R\u00e1diov\u00fd modul LTE Cat.4 bude schopn\u00fd pracova\u0165 len s jednou z t\u00fdchto frekvenci\u00ed.

Zariadenie triedy 12 bude schopn\u00e9 pracova\u0165 s troma nosn\u00fdmi kan\u00e1lmi: napr\u00edklad s dvoma na frekvencii 1800 MHz (1800+1800) a jedn\u00fdm na frekvencii 2600 MHz.

N\u00e1pad testu<\/h3>\n

\nTakto sa mi zrodil n\u00e1pad testova\u0165 routery r\u00f4znych kateg\u00f3ri\u00ed na zistenie re\u00e1lnej situ\u00e1cie, ktor\u00e1 sa otvor\u00ed be\u017en\u00e9mu pou\u017e\u00edvate\u013eovi. Probl\u00e9m spo\u010d\u00edva v tom, aby sa brali routery jednej s\u00e9rie alebo len s r\u00f4znymi r\u00e1diov\u00fdmi modulmi, preto\u017ee routery r\u00f4znych v\u00fdrobcov ur\u010dite bud\u00fa pou\u017e\u00edva\u0165 r\u00f4znu v\u00fdbavu, ktor\u00e1 m\u00f4\u017ee ovplyvni\u0165 v\u00fdsledky meran\u00ed. Preto som dospel k n\u00e1padu testova\u0165 iba jedn\u00e9ho v\u00fdrobcu, ale r\u00f4zne routery.<\/p>\n

Druh\u00fdm krokom bolo vybra\u0165 typ zariaden\u00ed na testy: m\u00f4\u017eeme si vzia\u0165 jednoducho router a pripoji\u0165 k nemu ant\u00e9nu cez zostavu k\u00e1blov, ale prax uk\u00e1zala, \u017ee pou\u017e\u00edvate\u013e chce z\u00edska\u0165 kombajn, do ktor\u00e9ho sta\u010d\u00ed zasun\u00fa\u0165 SIM kartu a zapn\u00fa\u0165 zariadenie do siete. Tak som dospel k n\u00e1padu testova\u0165 monobloky, teda router a ant\u00e9nu v jednom kryte. <\/p>\n

Tret\u00edm krokom som si ur\u010dil v\u00fdrobcu: Zyxel m\u00e1 naj\u0161ir\u0161iu ponuku monoblokov s r\u00f4znymi LTE kateg\u00f3riami, preto bol v\u00fdber jasn\u00fd. <\/p>\n

Na test som vzal nasleduj\u00face routery: LTE 7240, LTE 7460 a LTE 7480. <\/p>\n

Metodika testovania<\/h3>\n

\nAby sme ocenili schopnosti routerov, rozhodli sme sa vykona\u0165 trochu \"syntetick\u00fd\" test a re\u00e1lny test. Syntetick\u00fd test spo\u010d\u00edval v meran\u00ed r\u00fdchlosti na vzdialenosti pribli\u017ene 200 metrov od z\u00e1klad\u0148ovej stanice v osi vy\u017earuj\u00facej ant\u00e9ny, \u010do umo\u017enilo dosiahnu\u0165 lep\u0161iu \u00farove\u0148 sign\u00e1lu. Pripojenie bolo realizovan\u00e9 na ve\u017eiach Megafon, ke\u010f\u017ee zabezpe\u010dovali maxim\u00e1lnu \u0161\u00edrku kan\u00e1la 20 MHz pre toto miesto. Routery som testoval v dvoch regi\u00f3noch, kde na mape pokrytia oper\u00e1tor s\u013eubuje r\u00fdchlos\u0165 do 150 a 300 Mbit\/s. Re\u00e1lny test sa uskuto\u010dnil umiestnen\u00edm routera na mojej streche, kde som testoval predch\u00e1dzaj\u00face routery. Podmienky pripojenia v tomto re\u017eime s\u00fa ove\u013ea zlo\u017eitej\u0161ie, preto\u017ee vzdialenos\u0165 k ve\u017ei je 8 km a nie je priamy v\u00fdh\u013ead, pri\u010dom na ceste sign\u00e1lu s\u00fa prek\u00e1\u017eky v podobe stromov. Tak\u017ee sme uskuto\u010dnili tri testy:<\/p>\n

  1. Vzdialenos\u0165 k ve\u017ei ~200 m. Z\u00f3na s maxim\u00e1lnou deklarovanou r\u00fdchlos\u0165ou 150 Mbit\/s. \u010cas testovania 12-13 hod\u00edn.<\/li>\n
  2. Vzdialenos\u0165 k ve\u017ei ~200 m. Z\u00f3na s maxim\u00e1lnou deklarovanou r\u00fdchlos\u0165ou 300 Mbit\/s. \u010cas testovania 12-13 hod\u00edn.<\/li>\n
  3. Vzdialenos\u0165 k ve\u017ei ~8000 m. Nie je priamy v\u00fdh\u013ead. Z\u00f3na s maxim\u00e1lnou deklarovanou r\u00fdchlos\u0165ou 150 Mbit\/s. \u010cas testovania 12-13 hod\u00edn.<\/li>\n<\/ol>\n

    \nV\u0161etky testy sa realizovali s jednou a tou istou SIM kartou v pracovn\u00e9 dni. \u010cas bol zvolen\u00fd v okol\u00ed 12-13 hod\u00edn, aby sa predi\u0161lo rann\u00fdm a ve\u010dern\u00fdm \u0161pi\u010dkov\u00fdm za\u0165a\u017eeniam na BS. Testy boli vykon\u00e1van\u00e9 nieko\u013ekokr\u00e1t na dvoch r\u00f4znych servera<\/a> pomocou slu\u017eby Speedtest: Moscow Megafon a Moscow RETN. R\u00fdchlos\u0165 sa mierne l\u00ed\u0161ila, preto\u017ee servery<\/a> maj\u00fa r\u00f4znu z\u00e1\u0165a\u017e.
