The DI-624S Wireless 108G Storage 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
54Mbps 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 rthogonal F requency D ivision M ultiplexing) 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.
The DI-624S 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.
