Smartphones

How Do Smartphones Work?

On the surface smartphones function pretty much the same as existing mobile phones. Keypads resemble a cross between a mobile and PDA and the devices themselves are about the same size and weight as previous mobiles, and are usually lighter and smaller than PDAs. One big difference is that they can also access custom-designed content such as Java for Mobile Devices (J2ME). J2ME is accessible via the java applet on a smartphone and gives fast, relatively cheap access to a range of business friendly applications, such as desktop publishing, word processing, accounting spreadsheets etc.

So smartphones offer, in effect, the mobility of a handset along with the multifunctionality of a PDA.

More advanced models are also Bluetooth-enabled, connecting wirelessly and securely with other Bluetooth-enabled devices over short ranges to create local networks. Connectivity to other technology can also be achieved with IR (infrared), and for many models removable memory cards (of various sizes) are available.
