“One of the greatest pitfalls to bedevil a cell phone is a weak signal in your home or office. Not only is it a pain to have dropped calls when you’re trading the dish with your best friend, but it also pretty much negates the point of having a mobile phone if you can only make calls near your front window. But in the past couple of years, a variety of companies have identified the need for a real cell phone signal-booster. Unlike the foil decals you see in SkyMall, signal boosters like the Wi-Ex zBoost YX510-PCS-CEL cell phone signal extender actually improve your cell phone’s reception by significant levels. And, unlike the previous two products we’ve reviewed, Wilson Electronics SignalBoost and the Arc Freedom Antenna, the zBoost uses a wireless connection to your phone. [...] The zBoost works with both CDMA and GSM phones and operates on both the 800 and 1900 frequencies, so all major carriers and most U.S. cell phones are supported. Yet reception for your particular phone can vary by area. Carriers switch frequencies across different geographic regions, so it’s important to check that the zBoost you buy will be compatible with your phone. If you happen to purchase the wrong model, Wi-Ex will exchange it for free.”
