Each subchannel in the COFDM implementation is about 300 KHz wide. At the low end of the speed gradient, BPSK (binary phase shift keying) is used to encode 125 Kbps  of  data  per  channel,  resulting  in  a  6,000-Kbps,  or  6  Mbps,  data  rate.  Using quadrature phase shift keying, you can double the amount of data encoded to 250 Kbps  per  channel,  yielding  a  12-Mbps  data  rate. And  by  using  16-level  quadrature amplitude...

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  combined  with  a  transmitted  data stream to produce the output signal.
Wireless mobile clients receiving a direct-sequence...

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...

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.
The  802.11a  standard  gains  some  of  its  performance  from  the  higher  frequencies at  which  it  operates.  The  laws  of  information  theory  tie  frequency,  radiated  power and  distance  together  in  an...

TCP (Transmission Control Protocol)
The  standard  transport  level  protocol  that  provides  the  full  duplex,  stream  service on  which  many  application  protocols  depend.  TCP  allows  a  process  or  one machine to send a stream of data to a process on another. Software implementing TCP usually resides in the operating system and uses the IP to transmit information across the network.
