Japanese operator KDDI is planning to deploy LTE but will continue to use its existing CDMA network to handle voice traffic. During a keynote discussion at 4G World, Hideo Okinaka, vice president and general manager of emerging technologies and spectrum division at KDDI, said that the company has 20 MHz of spectrum for LTE and is currently working on specifications so that the network will fall back to 1X for incoming voice calls during a data session over LTE.
