Abstract

A wireless local area network (WLAN) method and device including at least one antenna to enable simultaneous dual band (SDB) operation of the WLAN device, the SDB operation including communication in a first frequency band with a first device and communication in a second frequency band with a second device, first network interface circuitry to support communication in the first frequency band with the first device, second network interface circuitry to support communication in the second frequency band with the second device, and a processor to generate an information element including information regarding the SDB operation of the WLAN device, and to enable transmission of the information element to the first device or to the second device.

Dependent claims

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 includes virtual DB operation including substantially sequential communication in the first frequency band and in the second frequency band with 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.

4 more elements

A method for use in a wireless local access network (WLAN) device, the method comprising:

enabling, through at least one antenna in the WLAN device, dual band (DB) operation, 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;
supporting, by first network interface circuitry, communication in the first frequency band with the first device;
supporting, by second network interface circuitry, communication in the second frequency hand with the second device;
generating, in a processor, an information element including information regarding the DB operation of the WLAN device;
and
transmitting, through the at least one antenna, the information element to the first device or to the second device,
wherein enabling the DB operation comprises enabling virtual DB Operation including sequential communication in the first frequency and case in the second frequency band,
wherein enabling the virtual DB operation comprises enabling sequential communication in a predefined time slot, the 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 a WLAN device is currently operating as the virtual DB device.
