A review of the Wi-Ex zBoost zPersonal Cell Signal Booster has been posted over at PaulStamatiou.com. 'The premise behind cell phone signal boosters, the zPersonal included, is pretty simple. There are two antennas. One goes nearest the area of the room where there is some cell phone signal reception. That signal gets processed and amplified through the powered unit and gets pumped out the other end, which you place close to where you need reception. Both antennas are used for receiving and transmitting, with the one mounted where there is reception being the actual end point talking to cell phone towers. It's important to understand that such a device cannot just make a signal. It has to use at least a weak signal to boost.
