Bluetooth's slow dawn

Bluetooth was developed initially by Ericsson as a short-range cable replacement for linking portable consumer electronic products, but it can also be adapted for printers, fax machines, keyboards, toys, games, and virtually any other digital consumer application. The technology provides a mechanism for forming small wireless networks of Bluetooth-equipped products on an ad hoc basis. It can also serve as a wireless bridge to existing data networks. However, hype has given way to hard work as expectations for the mini radio network encounter nettlesome interoperability issues.
