zdravim,
chtel bych se zeptat nakyho radiotechnika, co se stane ve chvili, kdy k bt vysilaci siemensu s55 pripojim antenu z wifi karty. jedna se o to, ze antena v telefonu ma urcity zisk a vysilac je staveny na urcitou zatez, nevim jake, v servisnim manualu o tom nepisou a zmerit to neumim. kdyz tam pripojim jinou antenu, at uz kus dratu (impedance 50 ohm, nepredpokladam ze se to bude technicky lisit od wifiny) nebo 5 dBi antenu z wifi karty (pres zlate sma konektory, at to nema ztratu), hlida si to nejaky diverzitni switch nebo neco takoveho? neudelal bych v podstate nic jineho nez k pcmcia karte napojil externi antenu (aspon si to myslim podle dostupnych informaci).
podle me pri velke zatezi se proste vypne telefon, to by nevadilo, tim bych vedel co to dela. ale kdyby se nevypl a nefungovalo to, tak nevim kde hledat problem.
k cemu to? nekdo po me chtel zvysit dosah bt vysilace na starem eriku t610, aby mohl nosit hf na zahrade a telefon mit pripojeny k pocitaci v pokoji nebo s tim ovladat pocitac. a u sebe mam moznost zkouset jen s 55.
