hField Technologies’ Wi-Fire is a compact high-performance USB Wi-Fi Adapter for Mac and PC that extends the Wi-Fi range upwards of 1,000 feet. Being a college student, I am blessed with a blanketed campus, offering a strong Wi-Fi signal wherever I go, right? …. Well, wrong. Dreaded dead spots exist and, to my dismay, my dorm room seems to be the epicenter of a dead spot, a barren wasteland of former Wi-Fi signal.

My solutions included hardwiring—too easy. Setting up a router? Forbidden. And as this epic conundrum reached a head, an epiphany hit me like a ton of bricks (as they tend to do). However, this epiphany came in the form of a small device called the Wi-Fire from a startup company that I had never heard of. The device triples the power of the internal receptor, making it virtually impossible not to get a signal, regardless of where you are.

On my current winter break, my internet cut out on me and, although I am not condoning it, I continued surfing without a problem off of an unsecured network down the street. The device uses a directional antenna with an arrow to ensure a strong signal. According to hField’s site, “the Wi-Fire provides interoperability with any 802.11 b/g access point and multiplies the effectiveness of wireless networks allowing users to connect to a WiFi network from up to 1,000 feet, more than three times the range of Airport cards and other 802.11 adapters, at significantly higher speeds, and even in locations where no wireless signal could be detected previously.”

If you’re looking to improve your internet connectivity and thereby improve your efficiency in any setting whether it’s the airport, park or even dorm room, look no further than this valuable gizmo from hField Technologies, Inc.

The device is 3 x 4 x 3/8 inches in size. It folds up for transportation and connects to the Mac and PC using USB. The device retails for $79 in the U.S.
