Can WiFi Solve VoIP's E911 Woes?

by Bruce Stewart

There's been speculation for some time that a WiFi-based triangulation scheme could be the solution to the VoIP E911 quagmire, but O'Reilly author and fellow VoIP blogger Ted Wallingford isn't buying it. He outlines a pretty convincing five-point argument as to why WiFi triangulation isn't going to be the E911 savior some are hoping for.

The problem is, WiFiTri, while possibly helpful and certainly scientifically valid, can never be reliable enough, inexpensive enough, or accurate enough to be considered a pragmatic idea.
