Permanent Link to Polaris Wireless launches 3D location platform for app developers
Polaris Wireless, a provider of software-based wireless location solutions, announced the commercial availability of a high-accuracy carrier-independent 3D location platform for application developers. By integrating their applications to the new platform, developers can provide end users with pinpoint location, including indoors and in high-rise buildings with floor level accuracy, delivering enhanced situational awareness and improved operational efficiency, according to the company.
Polaris Wireless has integrated its new platform with Orion Labs, Inc., a San Francisco-based company delivering instant and secure voice and location communication.
The Polaris Wireless 3D location platform is cloud-based and is available to application developers via a standard Android and iOS SDK. It can locate devices on the vertical axis within 3 meters, floor level, utilizing all available signals and sensor measurements combined with the company’s patented algorithms. By operating independently, or “over the top,” of wireless carrier networks, the platform is “universal,” enabling applications to locate any device on any network.
“Orion’s customers in hospitality, retail, healthcare, and public safety require pinpoint accuracy on a person’s location inside a building. Polaris Wireless’ platform helps us deliver that location capability, both for teams to see which floor they’re on or room they’re in, as well as to integrate location awareness with Orion Voice Bots and advanced AI-driven services,” said Jesse Robbins, Founder and CEO of Orion Labs.
Orion will demonstrate its solution based on the Polaris Wireless 3D location platform at the International Wireless Communications Expo (IWCE) in Las Vegas March 4-8 in booth No. 3371.
Polaris Wireless CEO, Manlio Allegra, will be participating in an IWCE panel titled “Impact of Enhanced Location Accuracy on Public Safety and 911 Services” on Wednesday, March 6 at 11:45 a.m.
