Wireless LAN Adapter
Spectrum24 Wireless LAN Adapter Product Reference Guide 9
Power Save Polling (PSP) mode allows the MU to conserve
power by suspending communication while still associated
with an AP. The AP saves data for the MU, which wakes at
given intervals to check for data. The WLAN adapter
drivers support dynamic power management, Algorithm
11 and 12 (refer to Appendix A for usage). Algorithm 11
varies the PSP parameter between 1 and 10 depending on
data traffic. Algorithm 12 switches the LAN adapter from
PSP mode to CAM, also depending on data traffic.
2.6 Card and Socket Services
The Spectrum24 WLAN adapter supports Card and Socket
services. In a DOS environment the WLAN adapter can
use Spectrum24 automatic configuration, hot insertion,
removal and power management features. Card and
Socket Service software packages providing these
features include SystemSoft, CardSoft or CardWizard
(not included).
The WLAN adapter supports Card and Socket Services
native to Microsoft Windows 95 but not in Windows NT.
2.7 Plug and Play
The Spectrum24 WLAN card Model 3020(PC Card) and
Model 3025 (ISA adapter) support Plug and Play systems.
This allows the PC to automatically recognize the WLAN
adapter, and configure the hardware interrupt, memory
and I/O addresses. This feature requires less user
interaction and minimizes hardware conflicts.
