    M2M “Machine-to-Machine” is two devices exchanging data without any human interference. It can be as simple as normal card access control or it can be as complex as a global sensor network connecting via multiple nodes into a single data repository to deliver data to a SCADA interface.


    With the explosive growth and merging of the internet and mobile telephony, the costs of sensors coming down, M2M is expected to become the fastest growing part of the communications industry.

    CWT(HK) Co., Limited

    With recent innovations in low cost satellite technology, the GAP platform extends the reach of Machine to Machine (M2M) communications beyond GSM, to anywhere on Earth.


    We make it easy to connect remote sensors, actuators and data loggers in remote locations. Now you can quickly provide end-to-end management, monitoring, control and reporting solutions using low cost equipment and simple software administered via the Web.


    CWT is used across multiple sectors, including utilities, environmental management and maritime
