Power Save Modes (CAM, FAST, Max)

Last Updated: Jan 29, 2014 10:40AM EST

In the Summit Client Utility (SCU) and Laird Connection Manager (LCM), power save mode allows you to set the radio to its optimum power-consumption setting.

Maximizing battery life for full shift operation is an important consideration for vendors and users of hand-held data terminals and similar devices. Summit provides a number power save modes that can significantly reduce the radio's power consumption and maximize the battery life of the host device.

Summit supports the three following power save modes:

  • CAM (Constantly Awake Mode) - keeps the radio powered up continuously to ensure there is minimal lag in response time. This power save setting consumes the most power but offers the highest throughput.
  • Fast - switches between PSP mode and CAM mode, depending on network traffic. For example, it switches to CAM when it is receiving a large number of packets and switches back to PSP after the packets have been retrieved. Fast is recommended when power consumption and throughput is a concern.
  • Maximum -  the access point buffers incoming messages for the radio. The radio occasionally 'wakes up' to determine if any buffered messages are waiting and then returns to sleep mode after it requests each message. This setting conserves the most power but also provides the lowest throughput. It is recommended for radios in which power consumption is most important (such as small battery-operated devices).
