Claim:
A gaming system implemented by a gaming establishment having a restricted gaming area in which wagering games are not permitted, and a non-restricted gaming area in which wagering games are permitted, the gaming system comprising: at least one game machine configured to receive a wager from a player to initiate a wagering game; a multilateration positioning system configured to transmit and receive one or more locator signals, the multilateration positioning system comprising: at least one game locator mounted to the at least one game machine; at least three fixed locators mounted at fixed positions spaced apart from each other; one or more processors; and at least one memory device including instructions that, when executed by the multilateration positioning system, cause the multilateration positioning system to: receive one or more locator signals, wherein each of the one or more received locator signals is transmitted by one of the locators at a transmittal time and received by one or more other locators at one or more arrival times; measure time differences of arrival between the arrival times of the one or more received locator signals; based on the measured time differences, determine an intersection of at least two hyperbolic lines of position associated with the at least three fixed locators, wherein the intersection identifies a location of the at least one game machine with respect to the restricted and non-restricted gaming areas; and wherein, in response to the at least one game machine being located in the restricted gaming area, the gaming system disables the at least one game machine such that the at least one game machine cannot conduct the wagering game while in the restricted gaming area.
