Cellular Phone Forum / General / GSM / June 2005Which band is SFR network on in France?
Have a reception problem in rural France, so want to try an external aerial. I need to know if it is 900 or 1800 mhz to get the right size. Thanks Brian. > Have a reception problem in rural France, so want to try an > external aerial. > I need to know if it is 900 or 1800 MHz to get the right > size. Surely you can buy a dual-band antenna. I have several dual-band 900/1800 MHz models. John > > Have a reception problem in rural France, so want to try an > > external aerial.

According to one specialist I spoke to, the dual band ones are a compromise, thus far lower performance. I just want to get the best I can, which will be a dual band one if I can't establish which band SFR is on.

Rural France + SFR = GSM 900 (precisely : ARFCNs 75 to 124)  SignatureCheers, Olivier > >> > Have a reception problem in rural France, so want to try an > >> > external aerial.

A dual band has to work reasonably well on two diverse frequencies and the fact that one is almost twice the other is close to a Radio Frequency Engineers worst nightmare come true. Bottom line is a design that works reasonable well for both will be no where near optimal for either! |
