Dobry den,
chcel by som sa spytat ci niekto ma uz skusenosti z realneho nasadenia zariadeni s podporou novej technologie 802.11ac. Hlavne ma zaujima rychlost a stabilita. Ci vobec nieco take ma vyznam v meste kde to pasmo uz je dost zarusene. A mozno aj odporucit dake zariadenia na 500m spoj bod bod.
Dakujem |

| ubnt zacali dodavat svoje prve AC produkty. Najprv je to Rocket M5 AC Lite. Neskor pride neorezana verzia AC Rocketu. Potom nasleduje PowerBeam (to je v podstate NanoBeam AC) a nakoniec by mali prist aj AC Nana. V meste by som bol asi opatrny s nasadzovanim radii. Mozno ked sa zacnu dodavat AC Rockety (nie Lite) a AC Nana, tak to mozno bude celkom dobre bezat. Samozrejme nie ja 80MHz kanale. To jedine na uzkosmerovych PtP spojoch. Ja by som s tym radsej pockal a nepokusal stastie s novymi este neodladenymi radiami. Toboz nie v meste. |

v zarusenom meste si to ani neprdne  acko v 20mhz s jednou polarizaciou tu chodi zle prave vdaka dvojpolarizacnym 40mhz srackam... takze prichodom 80mhz hrackam pojde 5ghz pasmo do kolien uplne... |
