3 - 8 Aironet PCMCIA Wireless LAN Adapter
Selecting a Channel Number, Bitrate and Frequency
The Channel Number parameter appears for all 1200 Series models and
the Bitrate and Frequency parameters appear for the Aironet 2200
Series only.
Keep in mind the following when selecting Channel Numbers, Bitrates
and Frequencies:
Appendix B
contains both North American and International bit
rates, frequencies and channel sets which can be used as a guide in
selecting the appropriate combinations for both 900 Mhz and 2.4
GHz models.
The tendency is to select the highest data rate available for the Cli-
ent Card. The trade-off, however, is that the higher the rate, the
lower the quality of the radio signal, and therefore, the shorter the
range a packet may be sent successfully.
If you find excessive interference on the channel or bitrate\fre-
quency you have chosen, try other channels, or combinations until
you find one that is more reliable.
Use the Linktest option to test the transmission quality between the
Client Card and other nodes on the Radio Network.
When you select the Channel Number parameter for 1200 Series models,
the 900 MHz Channel Set appears. Choose a channel number from the
available channel set.
When you select the Bitrate and Frequency parameter for the 2200
Series, the 2.4 GHz Bitrate and Frequency window appears. Choose a
bitrate and frequency combination from the set.
Setting the Priority
The priority setting is used by the radio MAC (Media Access Control) to
allocate access to the radio link. The higher the priority, the more likely
the Wireless LAN Adapter will be first to successfully transmit a packet
when multiple Aironet devices are trying to transmit at the same time.
The percentage of devices that are not using normal priority should be
kept low (10% or less).
