IR-UWB has been developed as a standard of indoor ranging technology because it has robust and good transmission characteristics in indoor environments and it can be operated with low power. In this paper, an IR-UWB MAC packet analyzer and a MAC test suite are designed and implemented based on IEEE 802.15.4a, which are useful in developing IR-UWB real time location systems with a resolution of a few ten centimeters. A sniffer device of the packet analyzer monitors IR-UWB wireless networks, captures MAC packet frames, and transmits packet frames to the packet analyzing computer. The packet analyzing program in a computer analyzes received MAC packet frames and displays parsed packet information for developing engineers. The MAC test suite serves as a role of higher layer for testing IR-UWB MAC functions one by one. Developed MAC development tools are used to analyze IEEE 802.15.4a MAC protocol, and it can also be used in other IEEE 802 series MAC protocol by modifying some functions.
