Abstract:
1. A wireless local area network (WLAN) device to provide dual band (DB) operation of the WLAN device, the DB operation including communication in a first frequency band with a first device and communication in a second frequency band with a second device, the WLAN device comprising: first network interface circuitry configured to support communication in the first frequency band with the first device; second network interface circuitry configured to support communication in the second frequency band with the second device; and a processor configured to generate an information element including information regarding the DB operation of the WLAN device, and to enable transmission of the information element to the first device or to the second device, wherein the DB operation include virtual DB operation including substantially sequential communication in the first frequency band and in the second frequency band within a predetermined time slot, wherein the virtual DB operation includes communication in the predefined time slot, the predefined time slot being divided into a first portion for communication in the first frequency band and into a second portion for communication in the second frequency band, and wherein the information element is sent prior to establishing communication and includes a field configured to include at least one bit to indicate that the WLAN device is currently operating as a virtual DB device.
