29. speed gradient BPSK binary phase shift keying is used to encode 125Kbps of data per channel resulting in a 6 000Kbps or 6Mbps data rate Using quadrature phase shift keying you can double the amount of data encoded to 250Kbps per channel yielding a 12Mbps data rate And by using 16 level quadrature amplitude modulation encoding 4bits per hertz you can achieve a data rate of 24Mbps The 802 11a g standard specifies that all 802 11a g compliant products must support these basic data rates The standard also lets the vendor extend the modulation scheme beyond 24Mbps Remember the more bits per cycle hertz that are encoded the more susceptible the signal will be to interference and fading and ultimately the shorter the range unless power output is increased Default Key This option allows you to select the default WEP key This option allows you to use WEP keys without having to remember or write them down The WEP keys generated using the Pass Phrase is compatible with other WLAN products The Pass Phrase option is not as secure as manual assignment Device Name Also known as DHCP client ID or network name Sometimes provided by an ISP when using DHCP to assign addresses DHCP Dynamic Host Configuration Protocol This protocol allows a computer or many computers on your network to be automatically assigned a single IP address from a DHCP server 22 DNS Server Address Domain Name System DNS allows Internet host comput
