W24 Wi-FiNow, M2M projects that require both broadband (Wi-Fi) locally and real-time (cellular) for remote access can exploit a single design solution. The W24 utilises the same form factor as other members of the Motorola M2M family, so you can easily integrate with existing designs. The W24 can be stacked with the G24 GSM module for smooth Wi-Fi to cellular data routing. |
