Reporters obtained the following quote from the background information supplied by the inventors: "Communications devices such as cellular telephones, mobile communication devices, personal digital assistants (PDAs), laptops, and the like are becoming more prevalent as technology advances make these devices more powerful and more affordable. And with the advancements in location determination technologies, location-based services developed for communications devices are becoming extremely popular. However, when indoors, location based services may be inconsistent or nonexistent."
In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "The following presents a simplified summary that describes some aspects or embodiments of the subject disclosure. This summary is not an extensive overview of the disclosure. Indeed, additional or alternative embodiments of the subject disclosure may be available beyond those described in the summary.
"In an example embodiment, global positioning system (GPS) signals may be integrated into radio frequency distributed antenna system (DAS) equipment. This may be accomplished via a real-time GPS combine and amplify system. Seamless GPS satellite signal visibility (accessibility) to any indoor GPS device may be accomplished. In addition to the relay of GPS satellite information, the GPS amplification system also may estimate altitude of a device with respect to ground level, tag antenna identification information serving the device, provide spatial (e.g., x,y,z) coordinates adjustments for navigating indoors applications, and the like. Accuracy performance of indoor location services may be enhanced by utilizing real-time global positioning system (GPS) amplification. Round-trip time (RTT) location responses associated with network assisted GPS (A-GPS) location requests for services from indoors call may be improved (shorter round-trip time).
