Abstract:
1. A terminal apparatus adapted for inter-terminal communication comprising: a communication unit configured to receive a packet signal which is a packet signal broadcasted from another terminal apparatus and includes an identification number for identifying the another terminal apparatus; and a notifying unit configured to notify that a packet signal including the same identification number has been received more than once during a predetermined period when the communication unit has received the packet signal including the same identification number more than once during the predetermined period, a processing unit configured to generate a packet signal to be broadcasted through the communication unit and to process a packet signal received by the communication unit; and a selecting unit configured to select a first mode or a second mode as a broadcast mode of the communication unit, wherein the communication unit sets first transmission power when the selecting unit selects the first mode and sets second transmission power lower than the first transmission power when the selecting unit selects the second mode, the processing unit includes an identification number uniquely allocated to the present terminal apparatus in a packet signal when the selecting unit selects the first mode, and includes an identification number different from the uniquely allocated identification number in a packet signal when the selecting unit selects the second mode, and the selecting unit selects the second mode when the communication unit has received the packet signal including the same identification number more than once during the predetermined period.
