A method for alerting a player about a wagering game machine is described herein. The method includes, when a ten millisecond periodicity is used for MulticastBroadcast Single Frequency Network subframes, setting a time between an uplink grant from the access node to the relay node and an acknowledgementnegative-acknowledgement message from the access node to the relay node equal to ten milliseconds. The localcast mode includes the ability to transmit and receive data in a peer-to-peer fashion, allowing mobile devices to communicate directly with each other. A process for manufacturing the memory element is also described.
