D-Link DWL-G120 [8/39] Wireless basics continued

Standards-Based Technology

The DWL-G120 Wireless USB Adapter utilizes the 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 (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 D-Link DWL-G120 will automatically

sense the best possible connection speed to ensure the greatest speed and

range possible.

The DWL-G120 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 up to 11Mbps in the 2.4GHz range.
