Takto vznikli ozna\u010denia 2\u00d72, 3\u00d73 a 4\u00d74. Ist\u00fd \u010das boli interpretovan\u00e9 r\u00f4znymi sp\u00f4sobmi, no naj\u010dastej\u0161ie sa vysvet\u013eovali po\u010dtom ant\u00e9n v zariaden\u00ed, ke\u010f\u017ee to bolo jednoduch\u0161ie na pochopenie.<\/p>\n\n\n\n

Wi-Fi 2\u00d72 sa be\u017ene ch\u00e1palo ako router podporuj\u00faci \u0161tyri ant\u00e9ny. Wi-Fi 3\u00d73, pomerne zriedkav\u00e9 ozna\u010denie, sa zvy\u010dajne opisovalo ako router so \u0161iestimi ant\u00e9nami, typicky dvoma pre p\u00e1smo 2,4 GHz a \u0161tyrmi pre p\u00e1smo 5 GHz. Wi-Fi 4\u00d74 \u010dasto ozna\u010dovalo routery s \u00f4smimi ant\u00e9nami, najm\u00e4 pri modeloch zalo\u017een\u00fdch na \u0161tandarde Wi-Fi 5.<\/p>\n\n\n\n

V r\u00e1mci marketingov\u00fdch vysvetlen\u00ed sa 1\u00d71 opisovalo ako dve ant\u00e9ny: jedna na vysielanie a jedna na pr\u00edjem. Existuje v\u0161ak aj technicky presnej\u0161ia interpret\u00e1cia t\u00fdchto konfigur\u00e1ci\u00ed.<\/p>\n\n\n\n

Presnej\u0161\u00ed sp\u00f4sob interpret\u00e1cie konfigur\u00e1ci\u00ed ako 1\u00d71, 2\u00d72 a 4\u00d74 spo\u010d\u00edva v zameran\u00ed sa na d\u00e1tov\u00e9 toky, nie na fyzick\u00fd po\u010det ant\u00e9n. V tomto v\u00fdklade prv\u00e9 \u010d\u00edslo predstavuje po\u010det vysielac\u00edch tokov a druh\u00e9 \u010d\u00edslo po\u010det prij\u00edmac\u00edch tokov.<\/p>\n\n\n\n

Konfigur\u00e1cia 1\u00d71 zah\u0155\u0148a jednu vysielaciu a jednu prij\u00edmaciu cestu a predstavuje z\u00e1kladn\u00e9 nastavenie bez technol\u00f3gie MIMO. Konfigur\u00e1cia 2\u00d72 vyu\u017e\u00edva dve vysielacie a dve prij\u00edmacie cesty, \u010do m\u00f4\u017ee za ide\u00e1lnych podmienok efekt\u00edvne zdvojn\u00e1sobi\u0165 potenci\u00e1lnu prenosov\u00fa r\u00fdchlos\u0165 v porovnan\u00ed s 1\u00d71. Konfigur\u00e1cia 4\u00d74 zah\u0155\u0148a \u0161tyri vysielacie a \u0161tyri prij\u00edmacie cesty, \u010d\u00edm \u010falej zvy\u0161uje \u0161\u00edrku p\u00e1sma oproti z\u00e1kladnej konfigur\u00e1cii.<\/p>\n\n\n\n

S pr\u00edchodom nov\u0161\u00edch \u0161tandardov, ako s\u00fa Wi-Fi 6 a Wi-Fi 7, tieto ozna\u010denia do ve\u013ekej miery stratili svoj v\u00fdznam. Modern\u00e9 \u0161tandardy zah\u0155\u0148aj\u00fa pokro\u010dil\u00e9 technol\u00f3gie na kombinovanie a spr\u00e1vu d\u00e1tov\u00fdch tokov, ktor\u00e9 nie s\u00fa striktne viazan\u00e9 na vidite\u013en\u00fd po\u010det ant\u00e9n ani na individu\u00e1lne vlastnosti routera. V mnoh\u00fdch pr\u00edpadoch boli tieto ozna\u010denia pou\u017e\u00edvan\u00e9 sk\u00f4r na marketingov\u00e9 \u00fa\u010dely ne\u017e ako presn\u00e9 technick\u00e9 parametre.<\/p>\n\n\n\n

V s\u00fa\u010dasnosti m\u00f4\u017eu ma\u0165 routery dve, \u0161tyri alebo \u0161es\u0165 ant\u00e9n a m\u00f4\u017eu pracova\u0165 v jednom p\u00e1sme (2,4 GHz), v dvoch p\u00e1smach (2,4 GHz a 5 GHz) alebo v troch p\u00e1smach (2,4 GHz, 5 GHz a 6 GHz). Preto je lep\u0161ie zamera\u0165 sa na podrobn\u00e9 technick\u00e9 \u0161pecifik\u00e1cie ne\u017e na p\u00fatav\u00e9 marketingov\u00e9 pojmy.<\/p>\n\n\n\n
