WPAN ( Wireless Personal Area Network Communication Technologies ) is a wireless connection to the personal area network. It is used in such as the telephone, computer, ancillary equipment and a small range ( personal area network working range is generally within 10 meters ) within the digital assistant communication between devices. Support wireless personal area network technologies include: Bluetooth, ZigBee, OC band ( UWB ), IrDA, HomeRF, the Bluetooth technology in the wireless personal area network used in most widely. Each technology has only been used for specific uses, applications or fields to play to the best effect. In addition, although in some respects, some techniques are considered in the wireless personal area network space in competition with each other, but they often each other is complementary.
The United States of America electronic and Electrical Engineers ( IEEE ) working group 802.15 is for wireless personal area networks make the definition of the organization. In addition to based on Bluetooth technology in 802.15, IEEE also introduced two other types: low frequency of 802.15.4 ( TG4, also known as ZigBee ) and the high frequency of 802.15.3 ( TG3, also known as super band or the UWB ). TG4 ZigBee for low voltage and low cost family control scheme for 20 Kbps or 250 Kbps data transfer speed, and TG3 UWB support for multimedia in the range of 20 Mbps and 1Gbps between the speed of data transmission.
