IEEE802 11h Local Administration MAC Network Max Service Period Length Network Type Power Saving Mode Radio On Off RTS Threshold SSID 27 4 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 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 A protection mechanism called RTS CTS that governs how 802 119 devices and 802 11b devices interoperate 2 Whatis the IEEE 802 11b standard The IEEE 802 11b Wireles
3. If there are only 802 119 wireless stations in the network you can set the card to this mode The available channel differs from different countries For example USA FCC is channel 1 11 Europe ETSI is channel 1 13 The operating frequency channel will be restricted to the country user located before importing If you are in different country you have to adjust the channel setting to comply the regulation of the country If you have a mix of 802 11b and 802 11g wireless stations in the network it is recommended to enable the protection mechanism This mechanism can decrease the rate of data collision between 802 11b and 802 11g wireless stations When the protection mode is enabled the throughput of the card will be a little lower due to many of frame traffic should be transmitted Auto Based on the status of the network and automatically disable enable protection mode On Always enable the protection mode Off Always disable the protection mode There are several options including Auto 1 2 5 5 11 6 9 12 18 24 36 48 54Mbps for you to select When the Auto is selected the device will choose the most suitable transmission rate automatically The higher data rate you designated in the network the shorter distance is allowed between the card and the wireless stations When the wireless mode is 802 11 B only the maximum data rate is 11Mbps 11b so that there are only Auto 1 2 5 5 11Mbps options you can selec
