In a wireless network, time slots may be configured in a manner such that the network directs portable wireless client devices to listen and respond within specific time slots. Because the time slots can be predicted or are known, one of the client devices may be configured to set a timer, enter a sleep mode, and then later awaken when a specific, time-slotted data interaction is required of the client device. Accordingly, battery power that would otherwise be consumed if the client device were active outside of the time slot may be saved.

What is claimed is: 1. An apparatus, comprising:a wireless transceiver having an active mode in which power is consumed, and a sleep mode in which power is conserved;a timer operatively coupled to the wireless transceiver used to indicate when to switch from sleep mode to active mode based on time s

What is claimed is: 1. An apparatus, comprising:a wireless transceiver having an active mode in which power is consumed, and a sleep mode in which power is conserved;a timer operatively coupled to the wireless transceiver used to indicate when to switch from sleep mode to active mode based on time slot assignment information received by the wireless transceiver; andprocessing circuitry operatively coupled to the wireless transceiver and the timer, the processing circuitry arranged to switch the wireless transceiver from the sleep mode to the active mode in response to input from the timer, the processing circuitry also arranged to monitor a first channel for a beacon during the active mode and, if no beacon is detected, increasing a channel number to a second channel and resetting the timer.
