Smart roam system and method

摘要

Systems and methods for determining when to switch wireless access points from a current wireless access point to a new wireless access point are disclosed. In various embodiments the systems and methods monitor a signal strength received from the current wireless access point, monitor a signal strength received from the new wireless access point and compare the signal strength received from the wireless access points. Switching from the current wireless access point to the new wireless access point can occur, for example, when the signal strength received from the new wireless access point is greater than the signal strength received from the current wireless access point by a first pre-determined value.

1. A method for determining when to switch a wireless device's connection from a current wireless access point to a new wireless access point comprising the following steps:
setting a previously monitored signal strength from the current wireless access point as a threshold; progressively monitoring a signal strength received from the current wireless access point, wherein monitoring takes into account one of signal-to-noise ratio and bit-error rate; monitoring a signal strength, received from the new wireless access point; comparing the signal strengths received from the wireless access points; comparing the received signal strength received from the current wireless access point with the threshold; pre-authenticating the wireless device with the new wireless access point prior to the steps of comparing the signal strengths and comparing the received signal strength from the current wireless access point with the threshold, wherein pre-authenticating the wireless device comprises pre-negotiating of one or more security associations; and the using pre-authentication to switch the wireless device's connection from the current wireless access point to the new wireless access point when the signal strength received from the new wireless access point is greater than the signal strength received from the current wireless access point by a pre-determined difference value and when the signal strength received from the current wireless access point is less than the threshold.
