  • Wireless terminal and roaming method using the same
    Patent number: 8553651
    Abstract: A wireless terminal roams from a first access point to a second access point. The wireless terminal can set a predetermined time period to determine whether to roam between different access points. Upon receiving signals from the second access point, the wireless terminal decodes signals received from the first access point and the second access point to get a correct probability of each bit of the signals. The wireless terminal then calculates mean values, a variance value and a difference in the mean values of the first access point and the second access point. If the difference in the mean value exceeds a product of the variance value and a roaming weight, the wireless terminal switches the wireless terminal from the first access point to the second access point to access the network.
