The Wireless Technology
Standard
The Wireless Access Point utilizes the 802.11b and the 802.11g standards. The
IEEE 802.11g standard is an extension of the 802.11b standard. It increases
the data rate up to 54 Mbps (108Mbps in Super G mode) 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 you’re 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 cross talk (interference) in signal
transmissions. The AP will automatically sense the best possible connection
speed to ensure the greatest speed and range possible. 802.11g offers the
most advanced network security features available today, including: WPA, TKIP,
AES and Pre-Shared Key mode.

Planning Your Wireless Network
Network Topology
A wireless network is a group of computers, each equipped with one wireless
adapter. Computers in a wireless network must be configured to share the
same radio channel. Several PCs equipped with wireless cards or adapters can
communicate with one another to form an ad-hoc network. The wireless
adapters also provide users access to a wired network when using an access
point or wireless router. An integrated wireless and wired network is called an
infrastructure network. Each wireless PC in an infrastructure network can talk
to any computer in a wired network infrastructure via the access point or
wireless router. An infrastructure configuration extends the accessibility of a
wireless PC to a wired network, and may double the effective wireless
transmission range for two wireless adapter PCs. Since an access point is able
to forward data within a network, the effective transmission range in an
infrastructure network may be doubled.
