Standards-Based Technology
The versatile DI-764 Multimode Wireless Broadband Router integrates both
802.11a and 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 high-speed 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, the DI-764 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.
