Table 5-6 lists and describes the client adapter's advanced ad hoc parameters. Follow the instructions in
the table to initially set or change any parameters.

Advanced (Ad Hoc) Parameters
Description
Specifies the antenna that your client adapter uses to transmit data.
• PC card – The PC card's integrated, permanently attached antenna
operates best when used in Antennas 1 and 2 mode (also referred
to as diversity mode). Diversity mode allows the card to use the
better signal from its two antenna ports.
Range: Antenna 1 Only, Antenna 2 Only, Antennas 1 and 2
Default: Antennas 1 and 2
LM card – The LM card is shipped without an antenna; however,
•
an antenna can be connected through the card's external
connector. If a snap-on antenna is used, diversity mode is
recommended. Otherwise, select the mode that corresponds to the
antenna port to which the antenna is connected.
Range: Antenna 1 Only, Antenna 2 Only, Antennas 1 and 2
Default: Antennas 1 and 2
PCI client adapter – The PCI client adapter must use the Antenna
•
1 Only option.
Default: Antenna 1 Only
Specifies the antenna that your client adapter uses to receive data. See
the Transmit Antenna Mode parameter above for information on the
options available for your client adapter.
These parameters are not available in ad-hoc mode.
Specifies the size of the data packet that the low-level RF protocol
issues to a request-to-send (RTS) packet.
Setting this parameter to a small value causes RTS packets to be sent
more often. When this occurs, more of the available bandwidth is
consumed and the throughput of other network packets is reduced, but
the system is able to recover faster from interference or collisions,
which may be caused from a high multipath environment
characterized by obstructions or metallic surfaces.
Range: 0 to 2312
Default: 2312
