Wavecom accelerates M2M Module test productivity with XJTAG


WAVECOM's "Wireless CPU" concept, by definition, is specifically tailored for the wireless technology of the CPU. In dealing with peripherals and computing, the Wireless CPU and traditional sense of the processor is not much different then, but its real value is its ability to handle a broad range of wireless protocol stacks, as well as real-time multimedia streaming, or to support a variety of wireless network environment, including cellular, GPS and a variety of wireless data transmission and so on.
