Cellphone amplifier boosts signals by factor of 10
Cellphone amplification technology for the car isn't new, but recent developments have made it more portable and affordable than ever before. Some of the newer in-vehicle amplifiers (priced around $280) work wirelessly with any handheld cellphone that uses 800 MHz or 1900 MHz cellular bands with AMPS, CDMA, TDMA or GSM and even Nextel's IDN — providing up to 10 times the boost on both the transmit and receive signal for as many as 3 devices simultaneously. We know what you're thinking, this thing is going to fry your noodle, right? Not so, see — the phone actually operates at reduced power 'cause it thinks it's much closer to the transmission site than it really is. Just don't try to conceal that radiating rear antenna in the child seat, ok? A version for Europe and Asia is in the works as is a model for amplifying the cellphone signal in your home — or are we just expecting too much?
