Chapter 5 Configuring the Client Adapter
Description
Keeps the client adapter powered up
continuously so there is little lag in
message response time.
Consumes the most power but offers the
highest throughput. Is recommended for
desktop computers and devices that use
AC power.
Switches between PSP mode and CAM
mode, depending on network traffic. This
mode switches to CAM when retrieving a
large number of packets and switches back
to PSP after the packets have been
retrieved.
Is recommended when power consumption
is a concern but you need greater
throughput than that allowed by Max PSP.
Causes the access point to buffer incoming
messages for the client adapter, which
wakes up periodically and polls the access
point to see if any buffered messages are
waiting for it. The adapter can request
each message and then go back to sleep.
Conserves the most power but offers the
lowest throughput. Is recommended for
devices for which power consumption is
the ultimate concern (such as small
battery-powered devices).
