For energy companies it could be smart meters that read themselves, increase business efficiency and cut operational expenses. In transportation - tracking solutions improve route optimization and safety for vehicles on the road. Digital signs that can be updated remotely, cameras that can send pictures halfway around the world and even a soda machine (drinks vending machine) that requests restocking when needed are other examples that machine-to-machine technology make possible." - Read full story here...
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.

GPRS is a packet oriented mobile data service; it is available for 2G cellular communication, GSM and 3G systems (modems, routers and embedded systems). GPRS provides data rates, this is the speed of data transfer from one medium to another. In 2G systems, GPRS sends 56-114kbit of data per second.
The GPRS protocol sits in the GSM, 2G and 3G network extending the circuit switch data (data transmissions) in order to allow;
- "Always on” internet access
- MMS and SMS
- PoC/PTT (Puch to talk)
- Instant messaging and presence – wireless village
- WAP (Wireless application protocol) to allow Internet applications for smart devices
- Point-to-point services via IP’s
The GPRS connection is established by reference to its access point name (APN). The APN defines the WAP (wireless protocol) access. An APN must be specified to permit a GPRS connection.
A Florida utility wants it customers to use remote managed thermostats. They offer it for free and even provide free installation. This allows customers to control the temperature from any internet enabled device.
Florida Power & Light Company will provide Internet-ready programmable thermostat, a remote control device that can be used when you’re at home, at work, or on vacation.
Along with not charging for the thermostat, FPL will install it for free. In return, the customer agrees to let FPL occasionally cycle the air conditioner for short periods of time, only when necessary, to conserve energy during heavy demand. However, the customer always has the ability to override the utility’s remote control over the air conditioner via the internet or by calling a toll-free number provided by FPL. FPL will also offer devices to control Pool pumps and Heaters..." - Read full story

RFI Engineering, a leading manufacturer of smart data solutions, intelligent port controllers, compact wireless gateways and remote management accessories, recognizing the vast and growing potential of programmable intelligent data solutions for the M2M market, today announced that it has added industry-standard VPN tunneling to its smart data router product-line.
Currently, the smart data router product-line consists of the G-router
(GSM/GRPS) and the C-router (CDMA/CDMA1x). The smart data routers are designed as an intelligent wireless data transmitter, including event monitoring and reporting from monitored equipment, which can be effectively deployed in sensor networks, smart metering and monitoring applications.
Smart data routers, such as the G-router and the C-router are able to set up a packet oriented data connection to the Internet using GPRS or CDMA1x. Most data connections offered by mobile operators are Internet centric, meaning they are to be used for Internet access. The smart data router is able to establish a connection to the Internet, but the device itself is hidden behind the Internet gateway of the network operator. This means that the data router itself can not be reached from the public Internet.
A solution is to establish a VPN tunnel between each smart data router and the customer's VPN server. For this purpose, L2TP (Layer 2 Tunneling
Protocol) VPN client support has been added to the feature set of the G-router and C-router. Customers can access the C-router or G-router directly, using their own L2TP VPN server.
"By adding a VPN client to our flagship product the G-router and the recently announced C-router, we have equipped our smart data routers with the possibility of establishing a secure VPN connection to a central VPN router, which offers customers a competitive edge by providing high-grade network security and reducing their total cost of ownership," says Peter Calis, CEO of RFI Engineering.
