SafeLink™ geolocation
technology is much more than a minor improvement to GPS. It is an
all-new, proprietary and patented geolocation solution with wide-area
urban and deep indoor coverage. No satellite-based system will
ever be capable of SafeLink's indoor penetration. And SafeLink's existing broadcast infrastructure is free.
SafeLink uses standard
commercial broadcast signals as position references. Their high power
levels and low frequencies are one billion times more effective
than GPS at reaching into the deep indoor and urban spaces where most
people spend most of their time on a daily basis. SafeLink has been
optimized for the civilian market.
Broadcast signals are
powerful, nearly immune to interference and jamming, and unaffected by GPS
disruptions. Measurement accuracy is superior to GPS in all
three axes. Safelink's blanket metropolitan coverage is
very difficult to evade. With SafeLink, protected persons and property “can't be lost”
indoors or out.
Applications include
mini-locators for persons, and embeddable chipsets for consumer
products such as cell phones and laptops. Subscribers can find
protected persons and devices remotely by telephone and on-line, and
receive locations as spoken street addresses. Location
information is private, available only to the service subscriber.
A working SafeLink
demonstration system is operating in Los Angeles, and a miniature
chipset development program is in progress.
