NTT Personal
At NTT Personal's booth, examples of many applications for PIAFS such as Internet Access, Picture Transmission etc. were introduced as well as the new PHS terminal "PALDIO" which became available this autumn.
DDI Pocket
DDI Pocket Group has announced the introduction of new wireless modem/facsimile service from the end of 1996 which provides 14.4 kbps, high-quality and versatile data transmission service at low usage fee through the existing network and could be a bridge to the forthcoming PIAFS service.
Compared with the former PHS data transmission on speech channel, media transformation function converts digital signal to analog at each PHS cell station (CS) to be able to utilize an existing NTT (Nippon Telegraph and Telephone Corporation) network for high-speed and error-free data transmission as illustrated in Fig. 1.
Thanks to this function, PHS subscribers can enjoy various high quality services such as E-mail, Internet Access, high-speed fax, PC Data File Transfer, Pager etc. by using one of the following three types of terminal equipment.
