I just got my first cellphone yesterday: a Motorola v60t with At&t. As this is my first cellphone experience I don't know what is standard quality of service. My concern is that I'm getting dropped calls inside my home and sometimes the busy signal is distorted, fades in-out with static in certain parts of the house. Is this normal for indoors? Also, any of you use those signal amplifiers, especially the one I see in commercials all the time? It's that metallic tape-like thing that you put on the back of the phone and supposedly it boosts signals and prevents dropped calls. Does it really work and is it worth the money? I am aware of cellphones causing health problems due to radio frequency(RF) radiation from the antenna. I've been doing some research on the net and according to CNET.com the motorola v60c(same phone for sprint PCS) has a 0.42W/Kg(watts per kilogram) rating. "According to the Cellular Telecommunications Industry Association (CTIA), SAR or specific absorption rate is "a way of measuring the quantity of radiofrequency (RF) energy that is absorbed by the body." For a phone to pass FCC certification, that phone's maximum SAR level must be less than 1.6W/kg (watts per kilogram). The SAR level listed in our chart represents the maximum SAR level with the phone next to the ear, a level obtained through required FCC tests." Being my phone is well below the FCC maximum, I wonder if this is my problem. Is the SAR proportional to the signal strength of the cellphone? If I do use one of those signal boosters modules, in effect I'm increasing the SAR of my cellphone am I not?
