| Companies wanting to build an M2M (machine-to-machine) solution integrating a WWAN (Wireless Wide Area Network, e.g. GSM/GPRS, CDMA or EDGE) communication function will typically opt to add a wireless modem (wireless module) to existing equipment. This approach generally yields a dual-processor architecture with a host processor (external microcontroller) and wireless modem (including a processor). The host processor carries out the application execution and interfaces with a set of external peripheral sensors, buses, memory etc., and it communicates with the wireless modem via AT commands.
For long-lasting competitiveness, however, developers of embedded systems need to focus on eliminating duplicate components and optimizing software development.
