The word “primarily” is important in this definition because of the trend toward
Making many devices capable not only of serving their own communication requirements
But also of serving as a node in a broader mesh network. Increasingly communication components, particulariy those using redio frequency communication, are being designed to provide functional options for supporting not only the direct requirements of the device in which it is embedded, but also functions for multiple distributed small devices, even very minute devices, can function as nodes on networks with a mesh topology
