Abstract: An information processing apparatus includes a radio module which wirelessly transmits and receives a packet through synchronous communication to and from another apparatus and a first controller. The first controller determines whether or not the packet transmitted from the radio module has been received by another apparatus, and selects, when reception of a previously transmitted packet by the another apparatus is not confirmed, between retransmission processing for retransmitting the previously transmitted packet and non-retransmission processing for transmitting another packet instead of the previously transmitted packet depending on a content of the previously transmitted packet.

Abstract: An information processing system is capable of communicating with an external apparatus via a network. The information processing system is capable of operating in at least three operation modes including: a first mode; a second mode, which consumes less power than the first mode; and a third mode, which consumes less power than the second mode and where the communication via the network is not performed. The information processing system includes a mode control section and a second mode processing section. The mode control section, when the information processing system operates in the third mode, shifts the operation mode to the second mode periodically or in accordance with a predetermined time schedule. The second mode processing section performs a communication process via the network as information processing in the second mode.
