Systems and methods for implementing a wireless device that supports WLAN modules operating simultaneously in different wireless bands

摘要

Systems and methods for enabling a WLAN client to communicate simultaneously over more than one band at a time are described, where each client has at least one radio that is operational in each supported band. Load balancing based on traffic requirements optimizes the use of the multiple bands.

1. A simultaneous client wireless device comprising:
a first wireless module configured to perform communication functions of the MAC (media access control) and PHY (physical) layers for a first wireless radio operable in a first wireless band comprising a first plurality of channels; a second wireless module configured to perform communication functions of the MAC and PHY layers for a second wireless radio operable in a second wireless band comprising a second plurality of channels; and a communication module configured as an intermediate layer between the MAC layer of the first wireless module and a network layer, and between the MAC layer of the second wireless module and the network layer, the communication module configured to:
use an application programming interface to retrieve information from the MAC layer and write information to the MAC layer of the first wireless module and to retrieve information from the MAC layer and write information to the MAC layer of the second wireless module, andmanage simultaneous communications with a wireless device over the first wireless band and the second wireless band, wherein the communications over the first wireless band and the second wireless band use a local area network protocol; wherein the client wireless device is configured to select any of a channel from the first plurality of channels and the second plurality of channels for communications with the wireless device based on a condition of the first plurality of channels and the second plurality of channels or a band from the first wireless band and the second wireless band for communications with the wireless device based on a condition of the first wireless band and the second wireless band.
