Standards-Based Technology

The DI-624 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 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 (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.

The DI-624 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.
