Switching to a single radio chain for voice communications

A computing device, comprising:

• a wireless wide area network (WWAN) radio chain arranged to communicate using wireless WWAN technology;
• multiple wireless local area network (WLAN) radio chains arranged to communicate using WLAN technology;
• one or more processors;
• and
• one or more computer-readable devices including instructions that, when executed by the one or more processors, cause performance of operations that include:
• determining, by the computing device, that the computing device has received a request to begin a full-duplex voice communication session with a remote computing system;
• identifying, by the computing device, that the computing device has wirelessly connected to both a WWAN access point that is communicating using the WWAN technology and a WLAN access point that is communicating using the WLAN technology;
• determining, by the computing device in response to having identified that the computing device has wirelessly connected to both the WWAN access point and the WLAN access point and having determined that the computing device has received the request to begin the full-duplex voice communication session, whether a level of non-voice session data that is queued for transmission or receipt by the computing device falls beneath a threshold level of data;
• and
• switching, by the computing device as a result of the computing device having determined that the level of non-voice session data that is queued for transmission or receipt by the computing device falls beneath the threshold level of data, to using a single one of the multiple WLAN radio chains, and communicating data over the single one of the multiple WLAN radio chains, including voice session data from the full-duplex voice communication session, in distinction to communicating data over more than one of the multiple WLAN radio chains, wherein communicating data over the single one of the multiple WLAN radio chains includes transmitting and receiving the voice session data, and transmitting or receiving the non-voice session data.
