Bluetooth in SEM Preparing SEM’s own competitive RF modules to meet the customers’ needs such as high speed wireless goods and personal area network environment (e.g : between PC to PDA) from April, 2000. SEM has already started to participate in the upcoming and blooming the wireless technology, Bluetooth and planned to launch the manufacturing by the 1st half of 2001.
