Standards-Based Technology
The DI-524UP Wireless Broadband Router utilizes the new
802.11g
standard.
The IEEE
802.11g
standard is an extension of the 802.11b standard. It increases the
data rate up to 54 Mbps within the 2.4GHz band, utilizing
OFDM technology.
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
(
O

F

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.
The DI-524UP is backwards compatible with 802.11b devices. This means that if you
have an existing 802.11b network, the devices in that network will be compatible with
802.11g devices at speeds of up to 11Mbps in the 2.4GHz range.
