Ericsson moves on Bluetooth
Roy Rubenstein in Stockholm Ericsson Microelectronics has unveiled its first two offerings for the Bluetooth short-distance wireless communications standard. It has developed a 2.4GHz Bluetooth radio transceiver, and has coupled it with a VLSI Technology ARM7 baseband processor to form a Bluetooth module. The company believes the wireless standard’s initial use will be to link users’ mobile equipment such as laptops and mobile handsets. “Bluetooth is a mobile LAN which follows you and the equipment you carry,” said Stefan L?f, Bluetooth product manager at Ericsson Components. Bluetooth’s migration into the office, as an access point to local area networks (LAN) and to replace cables, will then follow. L?f also sees a role in the home. Using a Bluetooth-enabled modem, a cellular phone could take advantage of cheaper, fixed-line call rates. Ericsson’s radio transceiver is aimed at companies which require Bluetooth-enabled products and have sufficient expertise to integrate it with the product’s existing microcontroller. Ericsson’s module, adding the baseband processor, is targeted at smaller companies which want to enter the market more quickly. The radio transceiver, in volume production at the year end, is expected to cost under $10. The Bluetooth module will appear in volume one quarter later costing under $30. L?f expects the first wave of products having a Bluetooth capability to be shown at the CeBIT show next year (March 2000). l US firm Silicon Wave has announced it is developing a Bluetooth transceiver IC which will interface to the host processor or microcontroller. The device will be available in the third quarter.
