Hitachi Cable, Ltd. is proud to announce the recent adoption of its wireless IP phone, the WirelessIP5000 in the trial deployment at the World Convention Center Summit at the Phoenix Seagaia Resort (Hamayama, Yamasaki-cho, Miyazaki-city, Miyazaki Pref. hereinafter referred to as Seagaia).

This trial represents the pilot event of the Wi-Fi RESORT SEAGAIA wireless LAN project, planned, proposed and supported as a joint effort between Minaminihon Network Co., Ltd. (headquarters in Miyazaki-city, Miyazaki Pref.; president: Saneaki Ozono) and PSI Inc. (headquarters in Shinjuku-ku, Tokyo; president: Koji Ohara) and implemented in partnership with Seagaia.

Falling prices and the advancing capabilities of today's data communication networks have led to rapid expansion in the deployment and use of IP phones, a voice communication application device based on the VoIP (Voice over Internet Protocol). As users seek even greater convenience, demand is growing for mobile IP phone solutions based on a wireless LAN environment.

Supporting SIP (Session Initiation Protocol) - a protocol on its way to becoming the standard VoIP communication protocol in Japan- our WirelessIP5000 is an open-style wireless IP phone capable of linking to IP Centrex services and SIP servers provided by multiple operators. The phone incorporates capabilities such as Auto Hand-over Function, which determines radio wave strength from access points and error status during communications to perform automatic handovers to optimal access points *1, and also implements a Presence Function (permitting rapid identification of the party status on the other end) and the Broadcast Mail Function. The phone fully complies with IEEE802.11b, the wireless LAN standard, allowing introduction using existing wireless LAN equipment. As a terminal providing a mobile IP phone solution, the new device has already found customers among numerous firms and organizations.

To create value for its customers and ensure improved guest service quality, Seagaia has built a new wireless LAN infrastructure and launched a trial to introduce a mobile IP phone system taking full advantage of this infrastructure. Adoption of our WirelessIP5000 as a system terminal provides TriplePlay service - IP phone, image transmission, and data communications - and provides customers with an Internet access environment as well as a means of communication while in transit in the hotel using the wireless IP phone, ensuring enhanced entertainment services through real-time transmission of relayed convention center images via the wireless LAN and delivery of images to satellite sites via the Internet.

To provide services for guests, a plan is currently being examined in which staff would carry the WirelessIP5000. The WirelessIP5000's extensive capabilities are expected to improve communications and enable more elaborate services.

A FUSION Mobile IP-Centrex solution supplied by Fusion Communications Corporation (headquarters in Chiyoda-ku, Tokyo; president: Tadahisa Sumida) is used to implement this trial run for the IP phone system, creating a mobile IP phone environment (extension and outside lines) without SIP servers or other on-site equipment. Two isolated IP phone/image transmission/data communication networks, one for guest Internet services and the other for hotel use, are implemented virtually on a single wireless LAN infrastructure, ensuring high security and reducing costs through flexible apportionment of the required bandwidth.

We are currently marketing the WirelessIP5000 through our sales partners. Our efforts to meet the demands of wireless IP phone users with reliable solutions is another sign of our desire to expand our share in the wireless IP phone market.
