    Nu prea merge antena aceea (desi are si AP), tinand cont ca e antena directionala.
    Ar trebui o antena omnidirectionala (desi e mai complicat tinand cont ca trebuie si outdoor si indoor).

    Se pot folosi extensii, de exemplu Fritz WLAN Repeater.

    bate aia linistit 400 m chiar daca e directionala...

    se poate folosi si varinta mai ieftina cu un repeater cum zice @Kroky

    iti coci creierii la 30dBm @ 2.4G

    Atentie, unitatea de masura este 2 W / kg.
    Cum telefonul mobil nu are 1 kg ci mai putin, si puterea e mai mica...

    Daca ar durea prostia cred ca ai racni de te-ar auzi si din SUA...

    Iar aia din link-ul tau, cand scriu de body nu se refera la body-ul telefonului!
    19,2°E + 0,8°W => DM800 + DM520 + VuZero

    Avantajul unui om inteligent este ca poate face usor pe prostul, invers e ceva mai dificil.....

    Nici un telefon mobil nu emite (in antena) cu 2W (vezi TS 25.102) ... nici chiar la marginea celulei. Nu mai zic ca puterea emitatorului UE este controlata (micsorata sau marita) in functie de puterea semnalului receptionat.

    Si acum, ma intorc la echipamentul de WIFi despre care am zis ca-ti coace creierii:

    Atentie! 30 dBm (1W) reprezinta puterea de emisie a echipamentului, nu puterea efectiv radiata de antena (EIRP)! Ai 30dBm la emitator peste care mai avem si un castig de 14 dBi deci puterea efectiv radiata izotrop este de 30dBm + 14 dB = 34dBm adica vreo 25W !

    Daca stai pe directia de radiatie a lobului principal al antenei la [email protected]
