47 results about "Geolocation database" patented technology

An Internet search engine ranks search results based on popularity with mobile-device users. Geo-position data from cell phones and other mobile devices are collected into a device geo-position database. The geo-position data is compared to locations of businesses in a business database. When a mobile device's geo-position moves inside a business location, a traffic counter for that business location in the business database is updated. When an Internet user performs a local search, the result set is sorted based on a rank that is at least partially determined by the traffic counters. The popularity-ranked search results indicate which businesses received the most mobile-device visits, an indication of the business's overall popularity. The popularity ranking may be adjusted for business size by dividing the traffic counter by the square footage of the business and sorting the result set based on the mobile-device visits, or repeat visits, per square foot.

A method of determining operating parameters for a secondary system transmitter is described. The transmitter characteristics, including location and operating frequency band, are provided to a geo-location database. The database determines the maximum allowable transmission power that meets various specifications for different channels and conveys the power and channel(s) to the transmitter. The database estimates channel incumbent signal strengths based on the transmitter location and primary and higher-priority secondary incumbent systems, estimates the splatter levels, determines whether adjacent and co-channel interference protection ratios are met, and adjusts the allowable power level accordingly. The database also estimates aggregate co- and adjacent channel primary and secondary incumbent system interference levels at the transmitter location and predicts channel quality for each allowable channel. The estimated levels are updated using measurements of actual levels at the transmitter location. The database dynamically allocates channels using the secondary system priorities.
