SafeLink^™ Geolocation

GPS and cellular geolocation systems cover the outdoors.
Only SafeLink^™ serves people where they live and work.

SafeLink™ is a revolutionary geolocation and messaging system that uses powerful existing commercial broadcast signals as position references, providing seamless coverage deep indoors and throughout large metropolitan areas. SafeLink's coverage not only reaches the places where people and assets are most often located, but it can measure locations precisely in all three dimensions.

How SafeLink Works:

1. Subscriber dials the SafeLink server, enters his account and password, and specifies a person (locator module) or device (embedded chipset) to locate.

2. The server connects to the module or chipset and requests location measurement.

3. The module or chipset performs measurements and reports results to the server. The server collects additional data from other SafeLink resources to ensure accuracy.

4. The server processes the data and reports results to the subscriber using computer-generated voice.

5. The subscriber may send a message,
i.e. - to disable a protected device.

6. Time required to obtain a location report by telephone is ~15 seconds.

Note: Alternatively, the subscriber may logon to the server via the Internet.

s Indoor penetration.

SafeLink location measurement technology uses existing commercial broadcast signals as position references. Commercial broadcasts are the strongest signals on earth and utilize frequencies designed to penetrate structures. As a result they are far more pervasive than GPS and cellular signals in urban and indoor environments where most people spend most of their time on a daily basis. SafeLink makes indoor positioning a reality.

s People and pets.

SafeLink subscribers can remotely locate their loved ones and pets wherever they may be, even if the protected persons are unable to operate a cell phone or to communicate with searchers. Tiny concealable locator modules operate without assistance from wearers, and are available in a variety of form factors for both humans and pets.

s Convenience.

SafeLink subscribers can access their services at any time from anywhere worldwide by telephone or online. On telephone connections, locations are reported by voice in terms of street addresses. With online connections, locations are displayed on high-resolution maps. Subscribers can disable items such as laptops by telephone or online.

s High-value assets.

SafeLink geolocation services keep subscribers tethered to their property. Embedded chipsets can't be defeated without destroying the product, and our pervasive indoor and urban coverage can't be evaded. With embedded SafeLink protection, consumer products "can't be lost." Subscribers can remotely locate and prevent unauthorized operation of valuable devices even when powered off and not in use.

s Measurement accuracy.

Horizontal position measurement accuracy is equal to or better than that of GPS, and optional altitude accuracy is far superior. For example, the specific floor in a building where people or property are located can be determined. Altitude is measured in terms of height above local terrain, a more useful metric than height above sea level.

s The future belongs to SafeLink.

No other technology - GPS, WiFi, cell triangulation, spectral signatures, U-TDOA or "hybrids" - can deliver pervasive indoor and urban coverage. SafeLink will dominate the geolocation and security industry, satisfying the worldwide demand for personal security services in places where most people spend most of their time on a daily basis.
