Chapter 5 - Appendix
This algorithm is established by IEEE 802.11b specifications. The bit redundancy
within the chipping sequence enables the receiving wireless mobile client to
recreate the original data pattern, even if bits in the chipping sequence are
corrupted by interference. The ratio of chips per bit is called the spreading ratio.
A high spreading ratio increases the resistance of the signal to interference. A
low spreading ratio increases the bandwidth available to the user. The wireless
device uses a constant chip rate of 11Mchips/s for all data rates, but uses different
modulation schemes to encode more bits per chip at the higher data rates. The
wireless device is capable of an 11 Mbps data transmission rate, but the coverage
area is less than a 1 or 2 Mbps wireless device since coverage area decreases as
bandwidth increases.
Encryption
This provides wireless data transmissions with a level of security.
Extended Service Set (ESS)
A set of one or more interconnected basic service set (BSSs) and integrated local
area networks (LANs) can be configured as an Extended Service Set.
ESSID (Extended Service Set Identifier)
You must have the same ESSID entered into the gateway and each of its wireless
clients. The ESSID is a unique identifier for your wireless network.
Ethernet
The most widely used LAN access method, which is defined by the IEEE 802.3
standard. Ethernet is normally a shared media LAN meaning all devices on the
network segment share total bandwidth. Ethernet networks operate at 10Mbps
using CSMA/CD to run over 10-BaseT cables.
Firewall
A firewall determines which information passes in and out of a network. NAT can
create a natural firewall by hiding a local network's IP addresses from the Internet.
A Firewall prevents anyone outside of your network from accessing your computer
and possibly damaging or viewing your files.
Gateway
A network point that manages all the data traffic of your network, as well as to the
Internet and connects one network to another.
IEEE
The Institute of Electrical and Electronics Engineers. The IEEE sets standards
for networking, including Ethernet LANs. IEEE standards ensure interoperability
between systems of the same type.
IEEE 802.11
IEEE 802.xx is a set of specifications for LANs from the Institute of Electrical
