    Support for Bluetooth™, Wi-Fi (802.11b) and 802.11a Wireless Networking
    3Com is one of the only companies developing Bluetooth and Wi-Fi (802.11b) wireless products, as well as supporting future use of the higher-speed 802.11a. As such, 3Com recognizes the complementary nature of these technologies, objectively playing to the advantages of each, and enabling them to coexist.


    • Bluetooth is designed for quick bursts of low-bandwidth (up to 1 Mbps) information in a cable replacement scenario within a PAN (personal area network). Bluetooth’s purpose and design allows small computing equipment such as notebooks, cell phones and handhelds to complete small data transfers using a less expensive, smaller footprint device and significantly lower power consumption. By 2005, 670 million devices will be equipped with Bluetooth wireless technology (Cahners In-stat Group, 2000).




    • Wi-Fi (802.11b) by contrast is normally used to extend or replace conventional wired LANs (local area networks), and is the ideal wireless LAN technology for transferring high-bandwidth files (up to 11Mbps) or for always-on Internet and office network connectivity. This type of wireless LAN can handle up to 65 users on any one access point, and works within a radius of 100 meters (330 feet). In Asia, the market for 802.11b is estimated to reach almost US$883 million by 2007, or almost 30% CAGR over 2000 in terms of revenue and almost 40% in unit terms (Frost & Sullivan Asia-Pacific, 2001).




    • Even faster transmission speeds – up to 54 Mbps -- are possible with 802.11a. This standard is yet to be ratified globally, its range is about 50 meters -- roughly half of that of an 802.11b network, and its price is high – which are all factors limiting commercial applications within the near term. However, some industry experts believe the very high speed this new standard offers makes it a potential alternative to the much slower 3G technology, especially in defined “hotpots” in such public areas as airports, commercial districts, etc. 3Com supports 802.11a, and will introduce products based on this standard once it has been ratified.
