Recently I have purchased a Smartphone and I am having the android operating system and I have a problem regarding the external booster. Wait I will explain in detail when I m working at the desk there is not having a single bar on the Smartphone but when walked near the window then I can get 2-3 bars and for full time but when I am at desk it does not show even one bar. So that is why I am looking for an external antenna. So is there any external signal booster which I can locate it on the desk or near the desk. Thanking all in advanced for giving me quantity replies.
