1. Bluetooth (I EEE 802.15)
 Bluetooth was conceived as a wireless replacement for a wired Ethernet.
 Bluetooth provides point-to-point links without any native IP support,
 Bluetooth is based around a 9mm by 9mm microchip that operates as
an inexpensive means of forming a short-range radio link that provides
 security for fixed wireless workstations as well as mobile computing
Devices such as PDAs.
 Bluetooth can network devices “ad hoc.” This means you can link your
laptop computer, PDA, and phone with one centralized Bluetooth
interface.
 Up to eight devices can be networked in a personal area network
(PAN), a conglomerate of devices connected in an ad hoc way using
Bluetooth.
 A piconet or PAN is formed when at least two devices (i.e., a portable PC
and a cellular phone) connect. A PAN can support as many as eight
devices. When a PAN is formed, one device acts as the master while the
others act as slaves for the duration of the connection.
 Signals can be transmitted through walls and containers, eliminating
the need for line of sight.
