Most jaded Wi-Fi users have moved beyond being awestruck that wireless networking works at all and have started complaining about the times when it fails to deliver a dependable connection. HField technologies is going after this problem with Wi-Fire, a $79 antenna that connects to a U.S.B. port on either a Mac or Windows computer (XP and Vista).
The palm-size antenna provides faster and more solid connections by combining a sensitive decoding circuit with a directional antenna that amplifies the signal. Pointing the antenna toward the base station can produce a signal that may be two or three times greater than one from a traditional antenna buried in a laptop.
