2000-07-01 Wireless future: At what cost?
I recently attended "Bluetooth Geneva," a conference sponsored by UK-based IIR Limited. Bluetooth, a proposal by cellphone makers Nokia and Ericsson along with computer makers IBM, Intel and Toshiba, is now endorsed by over 1,600 manufacturers. That this technology is hot is evidenced by the questions from the Taiwanese engineers at the executive panel discussion, "Interfacing for the Millennium," sponsored by Global Sources during the IIC-Taipei conference in May. Bluetooth was intended to link portable PCs and cellphones with a short distance wireless link. In principle, it will enable you to download an address book from your PC to your cellphone. Though it frequency hops at 2.45GHz, the Bluetooth transceiver was conceived as dumb, low power (10mW), and cheap.
