SAN JOSE While King Harald Bluetooth unified much of Scandinavia, the technology named after him still hasnt learned how to play nice. After five years of development, Bluetooth technology providers sought to establish the nascent technologys potential at the Bluetooth Developer Conference here this week. To reach it, the technology will have to learn to interoperate with the 802.11 WiFi protocols which share the same frequency. According to analyst firm the Zelos Group, by 2006 adoption and sales of Bluetooth wireless technology will result in $2.6 billion of incremental revenue for mobile operators in the US. But Bluetooth, the wireless technology that enables cable less connection of devices like PDAs, mobile phones and laptops, also shares the 2.4-GHz frequency spectrum with WiFi.
Consider a user who owns an 802.11-enabled laptop, a handheld PDA using Bluetooth and a wireless cell phone using either technology, executives said. If a user receives a call on the cell phone, will he be able to answer it and not affect the operation of the laptop and PDA? In most cases, the answer would be no: the user would either have cell phone connectivity or laptop connectivity, not both.
