Glossary
Access Point (AP)
A networking device that seamlessly connects wired and wireless networks. 
Access Points combined with a distributed system support the creation of 
multiple radio cells that enable roaming throughout a facility.
Ad Hoc
A wireless network composed solely of stations within mutual communication 
range of each other (no Access Point).

lower-speed subcarriers, which are then transmitted in parallel. Each high-
speed carrier is 20 MHz wide and is broken up into 52 subchannels, each 
approximately  300  KHz  wide.  COFDM  uses  48  of  these  subchannels  for 
data, while the remaining four are used for error correction. COFDM delivers 
higher data rates and a high degree of multipath reflection recovery, thanks 
to its encoding scheme and error correction.
Each...

Direct-sequence is a spread spectrum technique where the transmitted signal 
is spread over a particular frequency range. 
Direct-sequence  systems  communicate  by  continuously  transmitting  a 
redundant pattern of bits called a chipping sequence. Each bit of transmitted 
data  is  mapped  into  chips  and  rearranged  into  a  pseudorandom  spreading 
code  to  form  the  chipping  sequence.  The  chipping  sequence  is...

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...

physical-layer encoding scheme as Ethernet (only faster), 802.11a uses an 
entirely  different  encoding  scheme,  called  OFDM  (orthogonal  frequency 
division multiplexing).
The  802.11b  spectrum  is  plagued  by  saturation  from  wireless  phones, 
microwave  ovens  and  other  emerging  wireless  technologies,  such  as 
Bluetooth. In contrast, 802.11a spectrum is relatively free of interference.

Mbps within the 2.4 GHz band using OFDM (orthogonal frequency division 
multiplexing)  technology.  802.11g  allows  backward  compatibility  with 
802.11b devices but only at 11 Mbps or lower, depending on the range and 
presence of obstructions.

MAC Address (Media Access Control)
A  MAC  address  is  the  hardware  address  of  a  device  connected  to  a 
network.
NAT (Network Address Translation)
NAT  masks  a  local  network’s  group  of  IP  addresses  from  the  external 
network, allowing a local network of computers to share a single ISP account. 
This process allows all of the computers on your home network to use one 
IP  address.  This  will  enable  access  to...
