1. A wireless communication terminal, comprising:
- a radio frequency (RF) transceiver; and
a baseband processing circuit, which is arranged to detect an indication of a rate of movement of the terminal, and is coupled to cause the RF transceiver to scan periodically for access points that are available to communicate with the wireless communication terminal at a variable scan rate that is selected from among a plurality of different scan rates responsively to the indication, and upon detecting an available access point, to establish a wireless connection between the terminal and the available access point,wherein the baseband processing circuit is arranged to scan for the access points at a first scan rate when the terminal is moving at a pedestrian speed, and to scan at a second scan rate, lower than the first scan rate, when the terminal is stationary.

Abstract
A wireless communication terminal includes a radio frequency (RF) transceiver and a baseband processing circuit, which is arranged to detect an indication of a rate of movement of the terminal. The baseband processing circuit is coupled to cause the RF transceiver to scan periodically for access points that are available to communicate with the mobile terminal at a scan rate that is selected responsively to the indication, and upon detecting an available access point, to establish a wireless connection between the terminal and the available access point.
