While IEEE 802.11n has been adopted and established quite rapidly in consumer products and PC systems and the next, even faster standard is about to come soon, industrial automation lags behind a bit. Now, the practical problems of security and safety have been solved and corresponding products are ready for deployment.
The convenience of being able to connect devices without the use of wires has led to the enormous success of wireless technologies in the commercial sector, and these same techniques are now making a headstrong move into industrial environments. There are a few things to consider, however.
Machine-to-machine communication over mobile networks has challenges of its own. Depending on the application, quality of service can be crucial. That’s certainly the case in most industrial automation applications.
Machine-to-Machine communication is a term used for applications ranging from ultra-short range sensor couplings up to large automation networks. None of those pose problems in themselves, but difficulties have been known to arise at gateways to the internet.
