6 Troubleshooting
This chapter provides solutions to problems usually encountered during the installation and operation of the adapter.
1.What is the IEEE 802.11g standard?
802.11g is the new IEEE standard for
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
•Automatic Rate Selection
•RTS/CTS Feature
•Fragmentation
•Power Management
4.What is Ad-hoc?
An
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 for mobile workers.
