Wireless is everywhere! It's a mantra that's not new, but perhaps is taking on invigorated meaning with the explosion of wireless devices in seemingly every application space where embedded systems are deployed.
Driven by our insatiable need for information and the desire for finer control over every resource of value, it seems everything is becoming connected, and much of it is being done wirelessly. Fortunately today, adding wireless connectivity has never been easier.
In this article I'll introduce wireless terminology and basic design considerations, explain popular connectivity options such as Wi-Fi, Bluetooth, ZigBee and others, and examine hardware and software trade-offs, including design strategies, for easily and quickly incorporating wireless connectivity into an embedded design.
