1. A method of operating a positioning receiver, the method comprising:
- receiving, via a non-cellular terrestrial beacon network, location change information indicating a change in a location of a Wi-Fi hot spot, at the positioning receiver;
determining whether the positioning receiver has greater confidence in the location change information or in positioning signals received by the positioning receiver using the non-cellular terrestrial beacon network; and
calculating a position location of the positioning receiver using the one of the location change information or the positioning signals received by the positioning receiver using the non-cellular terrestrial beacon network in which the positioning receiver has the greater confidence.

Abstract
Wi-Fi-based location determination methods may include receiving location information and/or identifier information regarding a Wi-Fi hot spot, at a database. The methods may include transmitting the location information and/or identifier information regarding the Wi-Fi hot spot, from the database to a positioning receiver. Related systems are also described.

6. A system for Wi-Fi-based location determination, the system comprising:
-
a listening device configured to; receive signals from a Wi-Fi hot spot; and transmit location information of the Wi-Fi hot spot, only in response to a change in a status of the Wi-Fi hot spot, via a wide area non-cellular terrestrial beacon network comprising a plurality of beacons that are configured to transmit GPS-like signals for location determination of positioning receivers; and a database configured to; receive the location information of the Wi-Fi hot spot from the listening device, via the wide area non-cellular terrestrial beacon network; and transmit the location information of the Wi-Fi hot spot to a positioning receiver, wherein the positioning receiver is configured to receive the location information of the Wi-Fi hot spot via the wide area non-cellular terrestrial beacon network, wherein the positioning receiver is configured to calculate a position location of the positioning receiver, using one of; the location information of the Wi-Fi hot spot;
orpositioning signals received by the positioning receiver using the wide area non-cellular terrestrial beacon network, and wherein the positioning receiver is further configured to determine whether the positioning receiver has greater confidence in the location information of the Wi-Fi hot spot or in the positioning signals received by the positioning receiver using the wide area non-cellular terrestrial beacon network. - View Dependent Claims (7, 8, 9)
