Chapter 5 - Appendix

This algorithm is established by IEEE 802.11b specications. 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 congured as an Extended Service Set.

ESSID (Extended Service Set Identier)

You must have the same ESSID entered into the gateway and each of its wireless

clients. The ESSID is a unique identier for your wireless network.

Ethernet

The most widely used LAN access method, which is dened 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 rewall determines which information passes in and out of a network. NAT can

create a natural rewall 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 les.

Gateway

A network point that manages all the data trafc 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 specications for LANs from the Institute of Electrical
