OpenGate
OpenGate is a communications platform designed to facilitate a fast development and deployment of robust wireless solutions, to be used as a M2M platform or as a mobile platform.
OpenGate acts as a data gateway between remote devices and the applications that need to send and receive information to and from those devices. Making use of a very simple interface and thanks to the Internet, GSM/ GPRS and UMTS, OpenGate lowers the cost and the complexity of the implementation of wireless solutions, unifying the language of every connected device.
OpenGate has been designed to allow M2M and Mobile developers to concentrate on data exchange and data processing, instead of worrying about obtaining data in a secure and reliable way.
