D-Link DI-754 Product Manual - Page 8

Wireless Basics (continued) The DI-754 is compatible with other D-Link AirPro 802.11a products, which include: ♦ 5GHz Wireless Cardbus Adapters used with laptop computers (DWL-A650) ♦ 5GHz Wireless PCI Adapters used with desktop computers (DWL-A520) The DI-754 is also compatible with the D-Link AirPlus 802.11b wireless family (when you install the DWL-650+ into the expansion slot), which includes: ♦ Enhanced 2.4GHz Wireless Cardbus Adapters used with laptop computers (DWL-650+) ♦ Enhanced 2.4GHz Wireless PCI cards used with desktop computers (DWL-520+) Standards-Based Technology The versatile DI-754 Wireless Broadband Router integrates both 802.11a and optional (with D-Link DWL-650+) 802.11b standards into a single unit. The IEEE 802.11a standard designates that devices may operate at an optimal data rate of 54 Mbps (72 Mbps in proprietary Turbo mode.) This means that in most environments, within the specified range of this device, you will be able to transfer large files quickly or even watch a movie in MPEG format over your network without noticeable delays. This technology works by transmitting highspeed digital data over a radio wave utilizing OFDM (Orthogonal Frequency Division Multiplexing) technology. OFDM works by splitting the radio signal into multiple smaller sub-signals that are then transmitted simultaneously at different frequencies to the receiver. OFDM reduces the amount of crosstalk (interference) in signal transmissions. D-Link AirPro 802.11a products will automatically sense the best possible connection speed to ensure the greatest speed and range possible. Based on the IEEE 802.11b standard (when the optional D-Link DWL-650+ is installed in the expansion slot), the DI-754 is also interoperable with existing compatible 2.4GHz wireless technology with data transfer speeds of up to 22Mbps (with the D-Link AirPlus family of wireless devices), as well as standard 802.11b technology (the D-Link Air family of wireless devices), with speeds of up to 11Mbps. 8
