GPS vs. U-TDOA for Emergency Call Location

The two main technologies used to locate mobile phones are GPS and Uplink Time Difference of Arrival (U-TDOA). In perfect conditions, both technologies can perform well. But if the environment changes, like if a mobile phone is indoors or in a city with tall buildings, GPS has difficulty locating a mobile phone. This video illustrates why U-TDOA is the only technology that is uniquely suited for mission critical situations.

The Importance of Location

Mobile phones have become the dominant means of voice communication throughout the world. With mobile phones, a person calling an emergency number (9-1-1, 1-1-2, etc.) could be almost anywhere. Also, in emergency situations, people are often panicked or disoriented, and cannot provide their exact location. As a result, it is getting more difficult for government agencies to respond to emergency calls coming from mobile phones, and to send the appropriate emergency response resources. This video features real emergency call center professionals discussing the impact that high-performance wireless location technologies have had on their ability to process 9-1-1 calls in the United States, as well as the difference that location information makes in mission-critical, life-threatening situations.

An Interview with Stephen Stuut

Stephen Stuut, TruePosition CEO, discusses the evolution and growth of TruePosition as a location-based safety and security solutions company. He discusses how his career path and experience have shaped his leadership style and influence how he leads TruePosition today, and highlights what the future holds for TruePosition in the safety and security industry worldwide.

U-TDOA Overview

There are several wireless location technologies available, and each one is evaluated on performance in areas of accuracy, latency, and yield. U-TDOA is a completely network-based location technique that requires no modifications to the handset. It relies on multilateration using cell towers, making it well-suited for any environment, including indoors, urban, suburban. U-TDOA is uniquely suited for mission-critical safety and security applications because of its ability to consistently locate any mobile phone, in any environment with high accuracy and reliability.

An Interview with Directions Magazine

This interview with TruePosition’s Michael Amarosa, SVP of Public Affairs, and Brian Varano, Director of Marketing, features in-depth discussion of emergency call location. The interview includes history of the Enhanced-911 mandate in the United States and the call for stricter accuracy standards. Also discussed is an overview of the location technologies available, and specifically U-TDOA and hybrid technologies and why these techniques are best-suited for locating emergency calls from mobile phones.

Border Security Solutions

Wireless location intelligence creates an invaluable tool for monitoring and securing national borders. Wireless technology is being increasingly utilized to plan and execute illegal border crossings and criminal activity near borders. TruePosition LOCINT continuously compiles data about mobile phones and activity on the wireless network, enabling border security officials to remotely monitor activity on and around borders and detect threats earlier and more efficiently, significantly enhancing border protection methods

Critical Infrastructure Protection

Protecting critical infrastructure, such as power plants or transportation hubs, presents a unique set of challenges, and any breach to these facilities could have a devastating impact on the general public. TruePosition LOCINT continuously monitors mobile phone locations and activities in a predetermined area, providing an innovative tool to enhance current and future tactics, techniques, and procedures to extend critical infrastructure protection efforts, and can even help to expedite recovery after an incident occurs.

Law Enforcement Solutions

The use of wireless location intelligence can significantly expand current or future tactics, techniques, and procedures to fortify and extend law enforcement efforts. Because criminals frequently leverage wireless technology to commit crimes, they inevitably leave a trail of activities. TruePosition LOCINT identifies, tracks, and stores mobile phone location and activity information that can be leveraged by law enforcement to extend and improve the effectiveness of scarce crime fighting resources.

Emergency Call Location

As mobile phones become an increasingly dominant form of communication, an ever-growing number of emergency calls (911, 112, 999, etc.) are originating from mobile phones. Governments worldwide are facing the issue of how to process and locate these calls. The highly sensitive nature of these calls requires a high accuracy, low latency wireless location technology that will locate all mobile phones in any environment. This TruePosition solution, hinged on U-TDOA location technology, meets these requirements and, as a result, saves more lives.
