TOKYO—Yozan, a Tokyo-based software developer, on 2 April announced that the firm is going to launch Internet Protocol (IP)-based wireless service in the fourth quarter of 2002 by fully using both PHS networks that Yozan acquired from Tokyo Telecommunication Network earlier this week and wireless local area network (WLAN) networks.
According to Sunao Takatori, president of Yozan, the firm will construct WLAN networks in the Tokyo metropolitan area by putting a WLAN device on each of 4,000 PHS base stations in the area. The service will provide 32 kilobits per second (kbps) service for moving users, 2 Megabits per second (Mbps) service for users on the street and 8 Mbps service for indoor users. To launch the service, Yozan will provide a PC card-type terminal, an embedded terminal and a PHS-type terminal. Last year, Yozan acquired a beeper business unit from Japan Telecom for 1.6 million yen (US$12,100).
Yozan will provide its service comprising the PHS networks that Yozan acquired from TTNet, the beeper networks that Yozan acquired from Japan Telecom and wireless networks that Yozan will construct by itself.
