Embodiment Construction

[0098] Disclosed herein are systems, devices, apparatuses to, inter alia, restrict or even prevent / inhibit third parties from performing location determination processes (and also inhibit / block fingerprinting collection processes in order to inhibit location determination based on previously collected RSSI or RTT fingerprints) , products, media, methods and other embodiments. In some embodiments, implementations described herein limit / disable location determination functionality for unauthorized parties without affecting / impacting WiFi connectivity services and without limiting or interfering with location determination functionality for authorized parties, Location services for authorized users, applications and / or devices are also not compromised. Additionally, in some embodiments, the implementations described herein do not alter the content contained in or represented by the unprocessed or processed signal, nor do they interfere with the communication of the content repres...

Abstract

Disclosed are systems, apparatus, devices, methods, media, products, and other implementations, including a method that includes controllably modifying, at a first wireless device, an original unmodified value of at least one PHY-layer signal parameter, such as amplitude, frequency, timestamp, gain, signal equalization, and / or any combination thereof, of a signal according to at least one pre-determined varying signal modification process. The method further includes transmitting to a second wireless device the signal with the controllably modified value of the at least one PHY-layer signal parameter, with the transmitted signal configured to facilitate position determination of the second wireless device when the original unmodified value of the at least one PHY-layer signal parameter is determined at the second wireless device from the controllably modified value of the at least one PHY-layer signal parameter.

Description

Background technique [0001] One technique to facilitate position determination is based on the use of signal parameters of signals received at the device whose position / location is to be determined. For example, measurements such as round trip time (RTT), received signal strength indicator (RSSI), etc. may be used to facilitate position determination through techniques such as RTT fingerprinting, RSSI fingerprinting, and the like. [0002] The signal information needed for position determination, including indoor positioning determination using signals emitted by WiFi base stations, can be collected for essentially anyone with access to a venue. This can be problematic for site owners operating signal transmitting base stations, who may lose the benefits they may have received from providing location determination services that are being offloaded by 3rd parties (e.g., other mapping / location determination service providers) possible pecuniary benefits. [0003] Additionally,...
