  • Method and system for interfacing a machine controller and a wireless network
    Patent number: 8005425
    Abstract: A wireless interface module interfaces a machine control system, such as a vending machine controller, with one of plural wireless networks through one of plural removably coupled wireless transceivers. Communication between geographically distributed vending machines and a desired wireless network is supported by coupling a transceiver associated with the desired network to the wireless interface module. This advantageously provides flexibility in selecting from one of plural wireless networks for a distributed vending machine so that communication between the control system and a distal operating center is supported over a preferred wireless network through a standardized wireless interface module incorporated in the vending machine by changing the wireless transceiver removably coupled to the wireless interface module.
