Na obr\u00e1zku je vidie\u0165, \u017ee v\u0161etky zariadenia na frekvencii 2,4 GHz s\u00fa menej v\u00fdkonn\u00e9 ako na frekvencii 5 GHz. A to aj pri tom, \u017ee okolo nebol \u0161um z ru\u0161iv\u00fdch susedsk\u00fdch siet\u00ed, preto\u017ee v pr\u00edpade pr\u00edtomnosti ru\u0161enia na frekvencii 2,4 GHz by bol v\u00fdsledok v\u00fdrazne hor\u0161\u00ed. Napriek tomu je jasne vidie\u0165, \u017ee r\u00fdchlos\u0165 prenosu d\u00e1t na frekvencii 5 GHz je takmer dvojn\u00e1sobn\u00e1 v porovnan\u00ed s 2,4 GHz.

Ve\u013emi dobre sa ukazuje, ke\u010f fungoval router Keenetic ako repet\u00edtor, \u017ee r\u00fdchlos\u0165 prenosu sa rozde\u013euje na dve, tak\u017ee to treba bra\u0165 do \u00favahy, ak chcete pren\u00e1\u0161a\u0165 ve\u013ek\u00e9 objemy inform\u00e1ci\u00ed s vysokou r\u00fdchlos\u0165ou, a nie len roz\u0161\u00edri\u0165 pokrytie Wi-Fi siete.<\/p>\n

Na poslednom teste, kde Zyxel Multy X a Zyxel Multy mini sl\u00fa\u017eili ako adapt\u00e9r na k\u00e1blov\u00e9 pripojenie vzdialen\u00e9ho zariadenia (spojenie medzi z\u00e1kladn\u00fdm Zyxel Multy X a prij\u00edmac\u00edm zariaden\u00edm bolo bezdr\u00f4tov\u00e9), sa uk\u00e1zali v\u00fdhody Multy X, najm\u00e4 pri viacn\u00e1sobnom prenose d\u00e1t. Pozit\u00edvne sa prejavil v\u00e4\u010d\u0161\u00ed po\u010det ant\u00e9n u Zyxel Multy X: 9 kusov oproti 6 u Zyxel Multy mini. <\/p>\n

\nTak\u017ee je zrejm\u00e9, \u017ee aj pri nezaplnenej frekvencii 2,4 GHz m\u00e1 zmysel prejs\u0165 na 5 GHz, ke\u010f je potrebn\u00e9 pren\u00e1\u0161a\u0165 ve\u013ek\u00e9 objemy inform\u00e1ci\u00ed dostato\u010dne r\u00fdchlo. Pri tom, aj na frekvencii 2,4 GHz je celkom mo\u017en\u00e9 sledova\u0165 filmy v kvalite FullHD, pri\u010dom router funguje ako repet\u00e9r. Av\u0161ak film v 4K s norm\u00e1lnym bitrate u\u017e za\u010dne zasek\u00e1va\u0165, a preto router a zariadenie na prehr\u00e1vanie musia vedie\u0165 fungova\u0165 na frekvencii 5 GHz. Najv\u00e4\u010d\u0161ia r\u00fdchlos\u0165 sa dosiahne, ak sa ako bezdr\u00f4tov\u00fd adapt\u00e9r pou\u017e\u00edva s\u00faprava dvoch Zyxel Multy X alebo Zyxel Multi X+ Multy mini. <\/p>\n

A teraz k cen\u00e1m. Vysk\u00fa\u0161an\u00e1 dvojica routerov Keenetic Giga+ Keenetic Viva stoj\u00ed 14 800 rub\u013eov. A s\u00faprava Zyxel Multy X+Multy mini - 21 900 rub\u013eov.<\/p>\n
