The GSM quad band modem connects the WiWiz1 ,uSIM or any other device with an asynchronous serial port, to the cellular network. Information from the local wireless sensor network such as Wireless HART, Zigbee, ISA100, etc. can be sent over the cellular network from remote locations. Mobile networks can be built where the local sensor network is collecting data while in motion and sending data back to a website or server on a periodic basis. The GPS unit can be used for asset management to determine the location of tanks, containers and other movable systems. The device is programmed and controlled through a simple AT command software interface.
