Wilson Sleek 4G-V Wilson Electronics

LAS VEGAS--With its new Sleek 4G, Wilson Electronics brings some long-needed interoperability to cell phone signal boosters.

Debuting at CES, the Sleek 4G supports 4G LTE networks from all major U.S. carriers. And expect for Sprint's WiMax, it's also backwards compatible with existing 3G and 2G voice and data networks.

The Sleek 4G is very welcome since Wilson's 2012 products, the Sleek 4G-V and the Sleek 4G-A, supported the LTE of Verizon Wireless and AT&T respectively, but they weren't interchangeable.

Designed for use in the car or in your home or office, the Sleek 4G measures 4.5 inches long by 2.5 inches wide by 2.5 inches deep and weighs 3 ounces. Thanks to the adjustable arms, it fits a wide variety of phones, though when I tested the Sleek 4G-V, smaller phones tended to slip through.

I've used Wilson's previous products and have always found them to reliably boost cell phone coverage in areas with a poor signal. You can order it directly from Wilson and some third-party retailers for $199.95.
