Handheld terminal with functions of wireless ad hoc network has been applied in many fields such as military and marine .ad hoc network topology can be formed automatically by the terminal in the state of moving .And the terminal can complete voice communication and video transmission be-tween any two nodes by the multiple hops technology .In this paper ,the wireless ad hoc voice termi-nal controlled by ARM9 platform with S3C2440 processor as the core is designed and implemented . The voice compression module based on the AMBE-2000 and the wireless transmission module based on ZigBee protocol are regarded as the main function units ,and the users can achieve these functions through LCD touch screen . The results show that the terminal has many advantages such as low transmission bandwidth ,high quality ,good cost performance ,etc .
