Zdravim pani, viete mi poradit ako vyriesit link na 14km, kde potrebujem realnu prenosovu kapacitu 35 mbit/s? Momentalne to riesim cez Tsunami a MTI, ale idealnejsie by bolo pre mna prenasat to jednym radiom. Nebavme sa o licencovanych radiach a o 2.4 ghz  .
Skusal uz niekto routerboard a nstreame mod? Papierovo to vyzera dobre, ale mna by viac zaujimali prakticke skusenosti, ktore sa vacsinou dost lisia od informacii na papiery. Ak mate o tom, alebo o niecom inom nejake info plz napiste. Dik. |

35mbit/s je limitny datovy tok 5GHz radii v turbo rezime. Povazujem za prakticky nemozne tlacit takyto tok na 14km s touto technologiou.
Nevidim dovod, preco by si nemohol nasadit dva spoje paralelne. Cena jedneho spoja na baze Tsunami je cca 4-5 nasobok spoja na baze lacnejsich zariadeni.
Mimochodom, ake tam mas anteny a kolko dosahujes na jeden spoj? |

| Robert: lacnejsie zariadenia mi nezrobia na 14 km 20 mbit/s hd, anteny su tam 25 db |

| ja myslim ze ten spoj je zrely na licencovane pasmo, pokial s nim nechces mat v buducnosti zbytocne vela starosti... |

| Uz ti zostava skusit len to NSTREME v mikrotiku. Podla textov na www.mikrotik.com by to malo chodit celkom slusne. |

| v teoretickej rovine by sa to mozno dalo dosiahnut WAR boardmi a starosVX, ale zial prax je casto ina. |

| platit 100 000 rocne za prevadzku licencovaneho spoja sa mi nezda prilis rozumne, za tie peniaze tam radsej postavim na skusku mikrotik so 4 kartami o ktorom pisu ze by mal dosahovat rychlost okolo 80 mbit/s, len som chcel vediet ci s tym niekto nema prakticke skusenosti, nech to zbytocne nekupujem. |

Tak skus pouzit radia vo free pasme 24GHz (nemyslim 2.4GHz  ) alebo 61GHz a tusim je cosi volne aj v pasme okolo 38GHz.
Napriklad DragonWave AirPair100 je synchronne riesenie pre pasmo 24GHz s plnou 100Mbit full duplex prenosovou kapacitou (ma ethernet rozhranie). Cena je trochu vyssia 25 000 USD ale 100Mbit FDX je 100Mbit FDX a za frekvenciu nezaplatis ani korunu  Pripadne mozes pouzit 50Mbit verziu ...
Viac info tu:
http://www.dragonwaveinc.com/main.asp?i ... airpair100
a toto je dolezite:
Quote: › The AirPair 100 accommodates a variety of International licensed and unlicensed frequency plans including the new 24 GHz unlicensed spectrum.
Pasmo 24GHz je volne aj na Slovensku, najdes ho v tomto povoleni:

explorer, ma to 2 chybicky krasy:
1. Support Link distances up to 50 km (31 mi) with Licensed bands and 10 km (6 mi) with Unlicensed
Takze sme zase tam kde sme nechceli byt.
2. Za tych 25k$ si zozeniem tlupu ciganov a mi to tam za 2 tyzdne prekopu a polozim tam optiku
Idem skusit mikrotik a nstreame2 mod. |
