What is the IEEE 802.11g standard? 

802.11g is the new IEEE standard for high-speed wireless LAN 
communications that provides for up to 54 Mbps data rate in the 2.4 
GHz band. 802.11g is quickly becoming the next mainstream wireless 
LAN technology for the home, office and public networks.   
802.11g defines the use of the same OFDM modulation technique 
specified in IEEE 802.11a for the 5 GHz frequency band and applies it in 
the same 2.4 GHz frequency band as IEEE 802.11b. The 802.11g 
standard requires backward compatibility with 802.11b. 
 
The standard specifically calls for:   

A.

 

A new physical layer for the 802.11 Medium Access Control (MAC) in 
the 2.4 GHz frequency band, known as the extended rate PHY (ERP). 
The ERP adds OFDM as a mandatory new coding scheme for 6, 12 
and 24 Mbps (mandatory speeds), and 18, 36, 48 and 54 Mbps 
(optional speeds). The ERP includes the modulation schemes found 
in 802.11b including CCK for 11 and 5.5 Mbps and Barker code 
modulation for 2 and 1 Mbps. 

B.

 

A protection mechanism called RTS/CTS that governs how 802.11g 
devices and 802.11b devices interoperate. 

 

2.

 

What is the IEEE 802.11b standard? 

The IEEE 802.11b Wireless LAN standard subcommittee, which 
formulates the standard for the industry. The objective is to enable 
wireless LAN hardware from different manufactures to communicate. 

 

3.

 

What does IEEE 802.11 feature support? 

The product supports the following IEEE 802.11 functions: 

 

CSMA/CA plus Acknowledge Protocol 

 

Multi-Channel Roaming 

 

Automatic Rate Selection 

 

RTS/CTS Feature 

 

Fragmentation 

 

Power Management 

 

4.

 

What is Ad-hoc? 

An Ad-hoc integrated wireless LAN is a group of computers, each has a 
Wireless LAN card, Connected as an independent wireless LAN. Ad hoc 
wireless LAN is applicable at a departmental scale for a branch or 
SOHO operation. 

5.

 

What is Infrastructure? 

An integrated wireless and wireless and wired LAN is called an 
Infrastructure configuration. Infrastructure is applicable to enterprise 
scale for wireless access to central database, or wireless application
