Sony EMCS Corp., the Sony Corp. subsidiary that oversees all domestic manufacture, has developed a Bluetooth transceiver module for cellular phones and other digital devices.

Integrating peripheral circuitry with a baseband IC (integrated circuit) and a high-frequency radio IC developed by the U.S. firm Silicon Wave Inc., the new Bluetooth module is small and consumes just 40 milliamperes, around 20% less than comparable products from other companies.
