802.11g Wireless LAN Access Point Upgrade Kit
Significantly expand your wireless speed, coverage and user support with this easy to install 11g upgrade kit. The 11g radio supports an additional 128 users at speeds up to 54 Mbps at distances up to 100 meters (328 feet). The upgrade kit contains everything you need to add 11g wireless support to the 3Com Wireless Access Point 8200, 8500, or 8700 in minutes.
Because the 802.11g standard is backward-compatible with 802.11b, you can inexpensively upgrade or scale your existing 802.11b network, preserving your initial equipment investment. Or, add the 11g kit to a upgradeable 3Com access point to cost-effectively mix and expand wireless support for all three 802.11 clients -11b, 11a, and 11g-within the same coverage area.
Important: If the access point is used with an external antenna you must also purchase an antenna cable. For maximum efficiency, use the shortest antenna cable possible. Antenna cables induce signal loss, which will limit the radiated power output and range of the access point. Of the options available, we recommend the 3Com 6-Foot Antenna Cable (3CWE480).
Boosts wireless performance with transmission speeds up to 54 Mbps for 802.11g users (or up to 11 Mbps for 802.11b users) at distances up to 100 meters (328 feet)
Upgrade kit includes an IEEE-standard 802.11g radio in a mini PCI card, antenna module, radio-to-antenna cables, firmware on CD-ROM and user guide
Supports 3Com Wireless Access Point 8200, 8500, and 8700
Backward-compatible with 802.11b, preserving your existing wireless investment
Supports 128 simultaneous users, leaving plenty of room for growth
Diversity radio antenna provides both horizontal and vertical coverage within the transmission space, for optimum performance in high multi-path environments such as offices, warehouses, and other indoor installations
Four antenna options extend your 802.11g wireless connection range to up to 305 meters (1,000 feet); optional antenna cables give you more flexibility in access point installation locations
Wi-Fi certification ensures interoperability with Wi-Fi-certified products from other vendors
