1. What is t he IEEE 802.11g s tandard?
802.11g is the new I EEE standa rd for high-speed wirele ss LAN communi cations that
provides for up to 54 M bp s data rate in the 2.4 GH z band . 802.11g is quickly becoming
the next main stream wi reless LAN technology for the home, o ffice and public networks.
802.11g defines the u se of the same OFDM modulation technique specified in IEEE
802.11a for the 5 GHz f requency band and applie s it in the same 2.4 GHz f requency
band as IEEE 80 2.11b. The 802.11g standard requires backward compatibility with
802.11b.
The standard specifically calls for:
A. A new phy sical layer for the 802.11 Medium A ccess Control (MAC) in the 2. 4 GHz
frequency band, known a s the extended rate PHY (ERP ). The E RP adds OFDM as
a mandatory new coding scheme for 6, 12 and 24 Mbp s (mandatory speeds), and
18, 36, 48 and 54 M bp s (optional speeds). The ERP in clude s the modulation
