SpeedNet Inc. announced Thursday that it will start offering a high-speed wireless Internet service based on Tokyo Power Electric Co.'s optical fiber networks in parts of Saitama Prefecture on May 25.

The company will charge a flat monthly fee of 4,350 yen for 24-hour Internet connection at 1.5 megabits per second. What's more, no contract with a third-party Internet service provider is necessary.

Users can access the service with a satellite dish and tuner, which communicates with a nearby antenna base connected to optical fiber lines on Tepco's street-based electric power poles.
