TiPS Episode 26 0306 - Z-AXIS and Other Tales from the Crypt

Somewhere in a conference room, a vendor said the magic words, “We support Z-axis,” and everybody nodded like the problem was solved.

In this TiPS episode, Fletch takes you into the haunted parts of vertical location, where a Z value can be present, standards-compliant, and still operationally useless. We talk about why “support” is not the same as “actionable,” how the end-to-end chain (device, network, NG911 elements, call handling, CAD/map, human interpretation, responder action) can break at any link, and why the worst failure mode is when the number looks confident but should not be trusted.

You will also hear the uncomfortable truth nobody wants on a slide deck: height is not a floor. “Floor” is a decision, and buildings are chaos by design. Mezzanines, basements labeled “G,” towers that reset numbering, hospitals with “3 North” and “3 South,” all of it turns a simple meter value into a mapping and context problem. If your Z-axis plan ends at “the value exists,” this episode is your haunted house tour.
