Another Gimmick. Bluetooth Chomps At CES By Brad Smith Old King Harald would have been proud if he had been in Las Vegas last week for the 2000 International Consumer Electronics Show. The Danish king from the 10th century built his modern-day reputation as a team builder, not as a stone thrower. Harald also was known as Bluetooth, an appellation that he unknowingly provided for a wireless technology designed to bring together different electronic worlds. Many members of the Bluetooth Special Interest Group brought their products and product concepts to CES, an important step in gaining exposure for their work and to assure colleagues and consumers they are addressing compatibility issues in the wake of public concerns about radio frequency interference. Bluetooth, a technology to wirelessly connect handsets, laptops and other devices in relatively close proximity, is expected by analysts to become a $2 billion to $3 billion industry in the next five years as consumers are attracted to the convenience of wireless connectivity among home electronic devices. Since the protocol uses the unlicensed 2.4 GHz frequency band there have been concerns about interference between Bluetooth users as well as with other technologies, like wireless local area networks. Skip Bryan, an Ericsson manager who has been deeply involved with Bluetooth, said in an interview from the CES show that interference will always be a potential problem in unlicensed spectrum but that the Bluetooth standard is being developed to detect and correct any data transmission errors that may result. Bluetooth data packets are so small and transmissions so bursty that there shouldn't be a major impact anyway. Bryan also says he is convinced that Bluetooth can exist in harmony with such WLAN standards as the 802.11 specification, which also uses the 2.4 GHz band. Major 802.11 manufacturers like 3Com Corp., and TDK Inc. also are members of Bluetooth and want to assure compatibility. There also is a possibility that the two standards groups could work toward one compatible standard, especially since there is an 802.15 personal area network standard that points toward Bluetooth compatibility. Some Bluetooth SIG members think their standard ultimately will overwhelm 802.11 because the latter is aimed at only one use while Bluetooth encompasses much more. Market forces ultimately will decide that issue, the thinking goes. Among the Bluetooth products shown at CES was Ericsson's new headset, which wirelessly connects to a mobile phone. Intel Corp. also showed its “Ambler” Bluetooth radio module and integrated PC driver, which it expects to have in notebook PCs the middle of 2000. Also showing products were Acer, IBM, Lucent, Motorola, Nokia, Philips, Siemens, Sony and Microsoft.
