%X The short distance wireless system will become a research hot spot in a longer time, Personal Area Network (PAN impulse the development of personal information network. Main technologies include IEEE802.11b, Home RF, Bluetooth as well as ultra-wide band (UWB and so on. Because UWB has its unique characteristics, wider band, higher speed rate, lower power spectrum density and stronger anti-jamming etc, the UWB-based technology is focused on more deeply for these advantages. The paper emphatically introduced the physical channel model, the positioning technology and basic methods of positioning computing on UWB. Finally the latest development of node positioning system and algorithms are presented and summarized in this paper.
