) communication device comprising a wireless radio with multiple physical (“
PHY”
) transceiver cores;
alternately communicating in a time division manner across a first network channel and a second network channel using a first and a second of the multiple PHY transceiver cores together;
recognizing a first transition indication to operate in a simultaneous multiband communication mode, and in response;
allocating the first PHY transceiver core from the multiple PHY transceiver cores to communicate across the first network channel;
allocating the second PHY transceiver core from the multiple PHY transceiver cores to communicate across the second network channel, the second PHY transceiver core different than the first PHY transceiver core;
transmitting data across the first network channel using the first PHY transceiver core while simultaneously transmitting data across the second network channel using the second PHY transceiver core; and
receiving, at the first PHY transceiver core, a first beacon message sent by a first access point (AP) through the first network channel while simultaneously receiving, at the second PHY transceiver core, at least a portion of a second beacon message sent through the second network channel by a second AP that is different than the first AP.

Abstract
A system and method is presented to support simultaneous connections to multiple network connections. For example, a wireless radio of a communication device may be used to transmit or receive data from two network channels, each associated with a network connection. The communication device may allocate a first set of resources from the wireless radio to be used to communicate across a first network channel and allocate a second set of communication resources from the wireless radio to be used to simultaneously communicate a cross a second network channel.
