Er, if you have a wireless LAN, you might as well have router to an always-on internet connection, and say a Beaglebone Black for smarts to collect the data and forward it. That way you don't need any of these modules at all.
Excellent point!
Perhaps this would still be useful where no always-on internet connection is available - like an RV, or on a fleet of shipping trucks where you want to monitor a constellation of activities= speed, gas level, lights, engine status, reefer temps, etc.
Or, where you don't want to spend money for an always-on internet connection, like a vacation cabin (when empty).
