PURPOSE: An RIU(Radio Interface Unit) test apparatus in broad band wireless local loop is provided to measure and examine the capacity of RIU and BWLL(Broad Band Wireless local loop) terminal. CONSTITUTION: The RIU(Radio Interface Unit) test apparatus in broad band wireless local loop includes following units. A terminal(20) of BWLL is connected to the BWLL, thereby transmitting and receiving data to BWLL. Also, the terminal(20) performs data transmitting/receiving to the measurement device(30) by the second interface unit(120) consisted of RS_232C. A position measurement device(30) measures the position of the position measurement device by using GPS(Global System for Mobile) and reports it to a test device(110). The position measurement device(30) performs data transmitting/receiving to a control unit(100) of the measurement device(10) by the first interface unit(110). The test device(110) includes the first and second interfaces(110,120) composed of RS_232C and a user interface(130), and a memory(140). |
