SECURING RF (RADIO FREQUENCY) LOCATION TAGS USING SOURCE ADDRESSES TO LOCATE STATIONS ON A WI-FI NETWORK

摘要

RF tags using source addresses to locate stations on a Wi-Fi network are secured. An RF location server receives a pseudo source address of an RF (radio frequency) tag from a station. The station obtains the pseudo source address while being within radio range of the RF tag and the station receiving a beacon frame from the RF tag. A source address for the RF tag is looked-up utilizing the pseudo source address, and a specific location for the RF tag is looked-up utilizing the source address. Some embodiments store the locations in association with the pseudo address. Either way, the specific location of the station is identified based on the source address of the RF tag. An action is determined in response to at least the specific location of the station. Information related to the action is sent to the station for output to a user of the station. For example, a location-based offer or service can be provided in real-time with a consumer's presence to relevant products or services

主权项

1. A computer-implemented method executed at least partially in computer hardware for securing RF (radio frequency) tags using source addresses to locate stations on a Wi-Fi network, the method comprising the steps of:
receiving a pseudo source address of an RF (radio frequency) tag from a station, the station being within radio range of the RF tag and the station receiving a beacon frame from the RF tag, wherein the beacon frame comprises the pseudo source address in a source address field; looking-up a source address for the RF tag utilizing the pseudo source address, the pseudo source address stored with a plurality of pseudo source addresses each matched to at least one source address; looking-up a specific location for the RF tag utilizing the source address, the source address stored with a plurality of source addresses each matched to a location; identifying the specific location of the station based on the source address of the RF tag; determining an action based on at least the specific location of the station; and sending information related to the action to the station for output to a user of the station.
