Wireless Personal Area Networks (WPANs)

WPAN technologies allow users to build a wireless network (ad hoc) for simple devices such as PDAs, cell phones or laptops. This can be used in the personal operating space (personal operating space or POS). A POS is a space around the person, and can reach a distance of about 10 meters. Currently, two of the key WPAN technologies are Bluetooth and infrared light. Bluetooth is a cable replacement technology that uses radio waves to transmit data up to a distance of about 30 feet. Bluetooth data can be transmitted through the wall, pocket or purse. Bluetooth technology is driven by a body called the Bluetooth Special Interest Group (SIG), which publishes the Bluetooth specification version 1.0 in 1999. Another alternative way to connect devices within very close distance (1 meter or less), then the user can use infrared light merah.Untuk standardize the development of WPAN technology, the IEEE has been built for the 802.15 working group WPAN. This working group made WPAN standard, based on the Bluetooth specification version 1.0. The main purpose of this standardization is to reduce complexity, lower power
