Panel recommends technical norms for outdoor PC-Web connection.

TOKYO, May 7 Kyodo

An advisory panel to the government recommended a radio frequency Tuesday through which personal computer users in Japan would be allowed to connect their PCs to the Internet while outdoors, the government said.

The Information & Communications Council recommended PC users be allowed to connect their PCs to the Web in the radio frequency band of the 5 gigahertz level, the Ministry of Public Management, Home Affairs, Posts and Telecommunications said.

The ministry plans to revise related ordinances so private Internet service providers (ISPs) can begin offering the high-speed outdoor services by the end of the year, ministry officials said.

In April, Japan introduced wireless Internet hookup services for PC users based on the radio frequency band of 2.4 gigahertz.

But there has been interference between the radio waves used by ISPs and those used by corporate and individual users of local area networks (LANs), they said.

The interference has tended to disrupt or disconnect wireless Web data transmission based on PCs, they said.

To eliminate this problem, the panel has recommended authorizing

the use of the 5 gigahertz radio frequency band for outdoor Web data connection services.

This frequency would enable high-speed data transmission of up to 54 megabits per second. That is more than five times the speed of conventional PC-based wireless Web connection services.

It would also enable high-quality video, such as that for use in movies, to be transmitted to PCs via a wireless hookup.

The ministry assumes PC users will use the new wireless connection service in outdoor locations such as parks and towns and indoor environments such as condominiums and apartments, they said.

An outdoor wireless Web hookup, which entails only the construction of radio wave relay stations, would be less costly than the service requiring the laying-down of expensive fiber-optic networks linking ISPs with households or offices, they said.

The service ''would be useful in bringing broadband services to sparsely populated districts,'' a ministry official said.
