Scatternet

Using this approach, it is possible to join together numerous piconets into a large scatternet, and to expand the physical size of the network beyond Bluetooth's limited range.

A number of companies have attempted to launch social networking and dating services that leverage early scatternet implementations (see Bluedating).

Although it only runs on the emulation environment provided by Sun's Wireless Toolkit, it is capable of creating a scatternet of up to 15 devices and routing a message through the network.

In 2006, a student at the University of Technology, Iraq, developed an on-demand peer-to-peer scatternet routing algorithm and protocol,[5] with Java ME application based on JSR-82 library.

This application was tested successfully on several real life Java-enabled mobile phones, and is capable of building large scatternets, but its only practical when routes are less than 3 nodes long due to Bluetooth's speed.
