Targeting the enterprise market, KDDI has announced two VoIP telephony solutions: AirIP’s Office Freedom, designed to operate using the newly released E02SA handset via 802.11g, and Fujitsu’s Mobile Office, which appears able to run on a wider range of handsets using a BREW application. The Office Freedom system also suggests that GPS functionality will be available to track employee current locations… and recent movements!
Reports in the Japanese business press have suggested that publisher Bandai Namco is about to announce the launch of a new mobile gaming device, which would be aimed at the children’s market and launched with mobile network operator Willcom. The new service, Kids Mobile, would be co-launched by Bandai Namco and Willcom, a Japanese mobile operator which was spun out of major operator KDDI in mid-2004, and is now co-owned by Kyocera and the Carlyle Group.
Nippon Television Network, Japan Telecom and the East Japan Railway Co. group announced that they would start a joint experiment to air TV news inside trains. Japan Telecom will transmit the news to monitors inside trains via wireless LAN (local area network) devices installed at JR East stations. The partners plan to begin commercial operations from around July this year.
NTT DoCoMo, Inc. announced today that it achieved 2.5Gbps packet transmission in the downlink while moving at 20km/h. The fourth-generation (4G) radio access field experiment took place in Yokosuka, Kanagawa Prefecture on December 14, 2005. DoCoMo achieved a maximum 1Gbps speed in a similar field experiment on May 9, 2005. This time, by increasing the number of MIMO*1 transmission antennas from four to six and by using 64-QAM*2, data volume per transmission was increased from four bits to six bits. As a result, DoCoMo achieved a maximum speed of 2.5Gbps, which is faster than the International Telecommunication Union Radiocommunication Sector (ITU-R)’s proposed standard.
Just as every human being has a name, every computer is identified by a unique IP address. While humans are intelligent enough to distinguish two people with the same name, computers aren’t so clever. Computer IP addresses have to be unique. Luckily, domain names make it easier to remember popular Web addresses; after all, Internet searches would be very difficult if you had to remember unique IP numbers, which can run between 4 and 12 digits long. But even though domain names are widely used on the Internet, they are still an unexplored topic on mobile phones. In this article, I propose implementing DNS on mobile phones to simplify calls and service transfers.
A vendor of Linux-based network security and intrusion detection devices has been acquired by a major Japanese MVNO. Japan Communications Incorporated says that Arxceo’s devices will help protect mobile VoIP phone users, including dual-mode handset users. Arxceo markets Linux-based SMB firewall appliances, as well as small, Linux-based firewall devices. The small devices are placed between wireless networks and corporate networks, and provide behavior-based intrusion detection and prevention, the company says.
