Now get signal in dead zones also with the zboost from Wi-Ex, who has created a compact system that has the ability to boost the signal in the dead zone.
The system works with both GSM and CDMA phones and works with almost all mobiles.
All you have to do is to place the antenna were you get a strong signal and then the long cable attached to the device is to be unwound and with it move to a place were you have signal dip and then connect the cable to the phone you will see instant increase in the strength of the signal.
You can buy it from wi-ex website for around $400.
