RADIO PACKET TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve the throughput of the entire system by deciding an optimum size of a radio packet in response to a mobile speed of a radio packet transmission terminal and revising the original size of the packet so as to minimize a frequency of packet re-transmission and a time required for re- transmission of the packet. SOLUTION: A mobile speed detection circuit 14 detects a current mobile speed of a radio packet transmission terminal based on information obtained directly or via a radio interface 12 or a wired interface 11. A packet size decision device 15 stores an optimum packet size with respect to the mobile speed and decides a size of a packet corresponding to a detected mobile speed based thereon. A packet size converter 13 changes a size of a packet received from the wired interface 11. The packet whose size is converted is given to a radio interface 12, where the packet is converted into a radio packet and transmitted.
