The present invention can be used to facilitate the integration of wireless capability provided by wireless access points into an enterprise computer network. A gateway server is interposed between wireless access points and protected networks to provide security and integration functions, for example, authentication, access control, link privacy, link integrity, and bandwidth metering in various embodiments. Use of such a gateway server allows substantial control to be gained over network access even with the use of relatively simple access points. In general, such a gateway server receives a request to access the protected network. An authentication subsystem of the gateway server authenticates the user, preferably by accessing an external authentication server and returns a role to the authenticated user. An access controller in the gateway server provides differential access to the protected network based on the user's assigned role. A multiple gateway servers can be connected together to form a mesh network architecture.

A wireless device, system and method for receiving and playing multimedia files streamed from a multimedia server over a wireless telecommunications network. A desired multimedia file is selected from one or more multimedia files stored in the multimedia server, which server is operatively connected to the wireless telecommunications network. Successive blocks of data from the desired multimedia file are streamed over the wireless telecommunications network in a digitized and compressed format and received by the wireless telecommunications device. The received blocks of data from the streamed multimedia file are temporarily stored in a buffer in the wireless device, decoded and decompressed, and successively played through an audio and / or video output in the wireless device. The wireless device monitors the blocks of data stored in the buffer and signals the wireless telecommunications network to increase the rate that the data blocks are transmitted over the wireless network in the event that the data stored in the buffer falls below a minimum threshold level.

The invention provides a prize redemption system for use with one or more game apparatuses. A game is provided on a game apparatus for a player to play in exchange for monetary input, and prize credits are credited to the player based on the game outcome. A prize selection menu is then displayed by the game apparatus, the menu including one or more prizes, where the player may select a prize that has a prize cost within the player's prize credit amount. The player is dispensed a specific prize ticket that is redeemable for the selected prize. The game apparatus can also provide specific prizes and tournament games played for a tournament prize contributed to by multiple players. An operator can adjust prizes and payout percentages of the system to achieve a desired profitability for game apparatuses. Prize input is entered into a prize table describing multiple available prizes and also describing payout information that indicates a desired amount of payout that the operator wishes to provide back to players of the game apparatus in terms of the value of the prizes. Prize information, such as prize costs and specific prize win ratios, is automatically determined by the system for each of the prizes in view of the desired profitability of the game apparatus.Additionally, the invention provides method and article of manufacture for implementing a user profile-driven gaming and prize redeeming system. The user profile-driven gaming and prize redemption system allows for the tailoring of a user's experience of playing a computer implemented game on a network gaming system by first receiving an identifier selected from a group of identifiers including a user identifier relating to the user (i.e., player) of the network gaming system, a game identifier relating to a particular game played by the user of the network gaming system, and a site identifier relating to the location (i.e. web site) from which the game is being played. The network gaming system then alters the computer-implemented game played by the user in a manner based upon the selected identifier. The foregoing technique may also be applied to a prize redemption system.
