Fast PSP (Power Save Protocol / Power Save Mode)

Fast Power Save Protocol (Power Save Mode) is recommended for devices where power consumption is a major concern, such as small battery powered devices. It causes the Access Point to buffer incoming messages for the Wireless LAN Adapter card, which must wake up periodically and poll the Access Point to see if there are any buffered messages waiting for it. Fast PSP mode switches between PSP and CAM based on network traffic. When receiving a large number of packets, Fast PSP Mode will temporarily switch to CAM mode to retrieve the packets. Once the packets are retrieved, it switches back to PSP mode.
