Softbank Corp. will launch a wireless high-speed Internet access service using the infrastructure of its "Yahoo! BB" ADSL broadband network. Softbank units BB Technologies Corp. and Yahoo Japan Corp.,
which jointly operate "Yahoo! BB," will offer the new service with a transmission speed of 8.0 mega bits a second for a monthly charge of 2,280 yen. Softbank will start a trial service later in April.
Details such as the timing of the full launch and the service area haven't yet been decided. Users will be able to access the "Yahoo! BB Mobile " network by inserting LAN (local area network) cards
into their personal computers.
