The evolving and ongoing transition of wireless connectivity continues to increase the current number of non‑mobile wireless type 9‑1‑1 calling scenarios that may be more commonly presented as 9‑1‑1 emergency calls to Public Safety Answering Points (PSAPs). How 9‑1‑1 calls are presented on the Automatic Location Identification (ALI) screen may potentially impact how telecommunicators, Geographical Information Systems (GIS) mapping functions, Computer-Aided Dispatch (CAD) systems, dispatch, and downstream emergency response may be able to successfully interpret and use the information, including the location information, and to determine the appropriate or optimal emergency response given the presented information.

Some aspects of these non‑mobile 9‑1‑1 calling scenarios can be somewhat different from prior traditional Wireless Phase I (WPH1) and Wireless Phase II (WPH2) deployments. Traditional wireless 9‑1‑1 call WPH1 and WPH2 deployments generally involved wireless 9‑1‑1 calls scenarios from mobile handsets working off large macrocell coverage areas and scenarios where providing the wireless 9‑1‑1 caller civic location was either not feasible or was not being provided to the PSAPs. Examples of non‑mobile 9‑1‑1 calling type scenarios include Wireless Home Phone (WHP) adapter devices, consumer femtocells, voice calling from Wi‑Fi access point (Wi‑Fi calling) and the increased wireless carrier deployment of small cells and Distributed Antenna System (DAS) systems. These non‑mobile wireless‑type 9‑1‑1 calling scenarios may present the registered caller civic location instead of latitude and longitude coordinates associated with traditional wireless 9‑1‑1 call WPH2 deployments, or in the case of small cells or DAS systems may present materially smaller cell coverage areas than the macrocells associated with WPH1 deployments.

This document seeks to provide basic background information on these increasingly more common non‑mobile 9‑1‑1 calling-type scenarios and point out near‑term considerations that may appropriately fit for these scenarios.
