A flat-rate data communications service g@FreeDh (refer to the PHS MoU Group News No.45) was also shown. The hWRISTOMOh was especially popular with visitors.






3) Exhibits of other Participants

At the booth of SANYO Electric Co., Ltd., other than the hH"h based PHS camera phone gLeje H-SA3001Vh (see the separate article in this issue), a high-performance, small-sized PHS Cell Station (CS) based on Adaptive Array/Spatial Division Multiple Access technology and a future Advanced PHS base station were displayed on a monitor screen.
PHS terminals for the Chinese market were displayed at the Kyocera Corporation booth and various types of gAirH"h data communications cards were shown at NEC Infrontia Corporationfs booth.
Other booths displaying devices included PHS data communications cards for mobile providing compelling evidence that PHSfs application to mobile data communications has been spreading steadily.
