The CTIA Wireless Association recently announced that its largest members have agreed to a preliminary timeframe for improving the accuracy of 911 calls made from indoors. In February, the FCC demanded that wireless network operators increase 911 location data accuracy to cover larger buildings. It wants network operators to provide X, Y, and Z coordinates to help place callers as accurately as a specific room inside a building. AT&T, Sprint, T-Mobile, and Verizon Wireless have decided how they will approach the FCC's demands, and when they plan to meet select milestones. For example, they will verify technologies and vendor performance for indoor and outdoor technologies in a test bed in order to make sure gear sold by different companies all provide the same results. They will speed up the ability to provide dispatchable locations (street address plus floor, suite, or apartment) using indoor technologies, as well as create a database of each handset's performance in this regard. They will also improve all location technologies and tune them for better indoor and outdoor location fixes. The CTIA members said they will provide dispatchable locations for 40% of all wireless 911 calls within two years and 50% within three years. They will also provide dispatchable locations for 75% of all VoLTE calls within five years and 80% within six years. The FCC hasn't responded publicly to the CTIA's suggested framework.
