Over the past decade there has been a dramatic increase in the population of wireless transmitters found in the world. The “Internet of Things” has fueled demand for low cost, easy to implement chipsets to enable wireless connectivity. Engineers today have a variety of wireless solutions to choose from such as Bluetooth, ZigBee and all the flavors of WiFi (802.11). These chipsets are attractive because they utilize unlicensed radio spectrum and many solutions are available with reference designs which have already achieved regulatory approval.
