Wireless modules point the way for IoT connectivity

If there is one hardware feature that practically all embedded systems now have to have it is some form of network connectivity. For many devices, wireless connectivity is the smartest option. The wireless approach makes installation far easier, with a number of protocol options available depending on the application environment.

However, each wireless interface adds complexity if the design is performed from scratch. So the question is; do you build your own, or do you take the modular route with a ready-made, pre-tested solution? In the latest Engineers' Insight, Martin Keenan weighs up the options.
