A wireless communication device includes a processing unit with first chip and second chip that operates in parallel with the first chip. The first chip transmits/receives data according to LTE. The second chip transmits/receives data over a WLAN. The processing unit determines access points (AP) through which data can be transmitted/received by the second chip over the WLAN; and identifies an optimal AP, based on factors including a determination, for each AP, of whether transmission/reception of data by the first chip according to the LTE standard, simultaneous to transmission/reception of data over the WLAN by the second chip, would decrease the overall throughput of the first and second chips. When the second chip is previously connected to the WLAN through any AP other than the optimal AP, the second chip is disconnected from the other AP, and it is connected to the WLAN through the optimal AP.
