How can we use embedded systems (modules)?
To begin with, we can use embedded modules to perform one or more functions to a complete device such as, modem, fire alarm, GPS receiver etc.
Now, what are these functions?
1) Route data over wireless networks
2) Send SMS on alarm
3) Enable Internet access
4) Turn machines on or off from a remote office
5) Trigger functions on event (i.e. send e-mail on security brake in)
(Here is a nice diagram)
You get the idea.... the list is endless.
What kind of wireless networks can you access?
Well this depends on the module, there are different types of modules that can access different networks such as, GSM/GPRS, EDGE, GPS, 3G, HSPA/HSDPA etc. It all normally depends on your project requirements.
