Chcem sa spytat, ci je mozne v RB pouzivat 400mW karty. Niekde som cital, ze hrozi pretazenie miniPCI zbernice.
Okrem toho by som potreboval vediet, akym napatim je mozne napajat RB. Musim vyriesit napajanie cez cca 200m kabel 2 x 1,5mm (na 230V), v do ktoreho vsak 230V nie je mozne pustit z bezpecnostnych dovodov. |

| RB(532, 112) vie pracovat s napatim 12-48V takze ked mu pustis 48V tak na konci 200m kabla by teoreticky mohlo byt >12V |

ide to... netreba sa bat. co sa tyka chyrov, tak tie su urcene pre redukcie RB14 alebo RB18. V nich hrozi prepalenie cesticiek ci coho...
ale v RB532 mi to chodilo... |

Diky, tato odpoved ma potesila. Redukcie nejdem pouzivat, lebo nad viac ako 2ks miniPCI karty ani nemozem pri takom CPU uvazovat. |

Potrebujem dat 2x miniPCI do RB532A. 400mW potrebujem iba na vysielacej strane, prijimacia moze by standardna 50mW karta. Dufam, ze aspon takuto kombinaciu mi to utiahne. |

Pozeral som ponuku kariet s vyssim vykonom u Cechov. Zrazu sa toho vyrojilo velmi vela s dost odlisnymi cenami, takze neviem, co si vybrat. Uvadzam prehlad:
UBNT-XR5 miniPCI 5 GHz 600mW, Chipset: Atheros™, 6tá Generace, AR5414 s podporou SuperA/Turbo AR5213, Citlivost: -94 dBm, Cena 2109,40 Kc
UBNT-SR5 miniPCI 5 GHz 400mW, Chipset: AR5213, Citlivost: 6 Mbps -94 dBm, +/- 2dB, 54 Mbps -74 dBm, +/- 2dB, Cena 2109,40 Kc
Alfa AWPCI085H miniPCI 500mW, Chipset: Atheros(AR5006X AR5414), Cena 1090,- Kc
CM11-HP miniPCI (max 400mW), Chipset: Atheros AR5414A, Citlivost: -96 dBm, Cena 1150,- Kc
R52H miniPCI High Power 350mW, Chipset: Atheros AR5414, Citlivost: -95 ( 1 mbps) až -71 ( 54 mbps) dBm, Cena 930,- Kc
Zatial sa mi ako najlepsia volba zda UBNT-SR5/XR5 kvoli najvyssej citlivosti, ale ta je aj najdrahsia. V pripade full duplex by sa mozno dalo vsadit na R52H. Zatial uvazujem nad Nstreme (Half duplex) na velku vzdialenost. Poradte. |

| ja mam UBNT-SR5, XR5 este nebola a je naozaj super, citlivostou sa nic nechyta. Podla merani zhruba o 3db lepsi signal. |

Tak potom technicke udaje neklamu. Pre 54mbit/s sa bezne uvadza citlivost -71dBm a u tejto karty je to -74dBm.
Zatial mienim vsadit na tu UBNT-SR5, pokial je naozaj citlivejsia ako ostatne a dokonca ma aj mensiu spotrebu. Ta je v RB rozhodujuca. |

Tiez radsej odporucam SR5, s XR5 som mal problem, ze v pIII v redukcii z bgs(minitar) sa po zapnuti karty restartne pocitac. Toto iste mi robila CM11. Az po nastaveni TX-power na 10db sa to da zapnut.
SR5 absolutne v pohode. |
