Bluetooth

Bluetooth is a short-range radio technology that creates a simpler method
of communicating across networked devices and between devices and the
Internet. It also simplifies data synchronization between net devices and
other computers (Figure 1.5).
Products with Bluetooth technology must be qualified and pass interoperability
testing by the Bluetooth Special Interest Group prior to
being released on the market.
The Bluetooth 1.0 specification consists of two parts: a foundation
core that provides design specifications and a foundation profile that
provides interoperability guidelines.
Bluetooth was created in part through the cooperation of several companies
including Ericsson, IBM, Intel, Nokia, and Toshiba.
