(FHSS) technique or direct sequence spread spectrum
(DSSS), which is also known as CDMA. The 802.11b
standard defines an 11 Mbps data rate in the 2.4GHz band,
802.11g-draft standard defines 54 Mbps in the 2.4GHz band,
and the 802.11a standard defines 54 Mbps in the 5GHz band.

In order for your wireless components to interact with
traditional wired networks they need a media bridge to
translate for them. This is where INFRASTRUCTURE
or Network mode comes into play. An ACCESS POINT
is attached to the network using CAT-5 Ethernet cable
attaching to a hub, switch or another PC. Wireless PC's
can then communicate to Wired Ethernet computers
through this access point. The total range of the network
is limited to a radius around this Access Point. To increase
the range, extra Access Points may be wired into the
network. These Access Points talk to each other over
the hard-wired Ethernet cables however, they cannot
communicate wirelessly to one another and they must
be wired to the same network. Individual wireless PC's
can move between Access Points on the same network
seamlessly due to a feature called ROAMING.
o
Tx-Rate or TRANSFER RATE is the current speed at
which the network component is operating. SMC-802.11b
products can operate at speeds of 1Mb, 2Mb, 5.5Mb,
& 11Mbps. A wireless card set to AUTO will attempt to
connect at whatever speed will give the best throughput
on the network.
