Many of you might have played cat and mouse with WiFi signals inside your home. WiFi coverage tends to be inconsistent if the client and the WiFi access point are separated by walls. But a Sunnyvale-based startup, Quantenna Communications, is readying three chipsets to ensure that you don’t have to search for WiFi sweet spots inside you house ever again.

The chips will not only prevent WiFi signals from loosing their strength while traversing walls but also reign in on any interference from other devices operating in the 2.4 or 5GHz bands. The chipsets are expected to cost between $20 and $40 each. These chips are expected to make their maiden commercial appearance sometime in 2009.
