Performances analysis of TCP/IP communication using 384-kbit/s PHS experimental system
Fumihide Kojima, Yukiyoshi Kamio, Masayuki Fujise · 2002
The maximum transmission rate in public mobile data communication services such as PHS (Personal Handyphone System) is currently limited to 64 kbit/s in Japan, but a higher transmission rate will be needed in order to meet the requirements of mobile multimedia applications. We have therefore developed 384 kbit/s-PHS experimental system that uses the 64 kbit/s PHS data communication protocol (PIAFS) and the PPP multilink protocol. This paper presents the implementation and performance evaluation of the 384 kbit/s-PHS experimental system. The throughput performance of the system is evaluated using FTP under various radio propagation environments.
