TOKYO—A governmental advisory body for the telecommunications ministry on 16 January decided to revise the telecom regulation to let operators use the OFDM system for their wireless local area network (WLAN) services.
Using the OFDM system, operators will be able to provide high-speed data transmission services with a speed of more than 20 Megabits per second (Mbps). Using the conventional system based on the international standard of IEEE 802.11b, wireless LAN operators are currently providing service with up to 11 Mbps.
The revision of the regulation is scheduled to be enforced by the end of February.
Sony and Japan Telecom are planning to launch a field test for WLAN based on the OFDM system in February.
