Methods, systems, and apparatus for parallel scanning of channels in communication networks are described herein. A parallel scanning device performs a scanning operation that includes parallel (i.e., simultaneous) scanning of channels that are in a common frequency band or in different frequency bands. The parallel scanning of channels results in a reduction of scan time, which reduces power consumption. Furthermore, a scanning operation may undesirably interrupt and/or delay normal communication traffic to and from the parallel scanning device, and the comparatively shorter scan time resulting from the parallel scanning operation can reduce such interruption and/or delay.

Parallel scanning of wireless channels

A communication circuitry includes a media access control including a first wireless interface and a second wireless interface. An application processor includes a network stack connected with the media access control. A communication packet is routed from the first wireless interface to the second wireless interface or from the second wireless interface to the first wireless interface without sending the communication packet to the network stack.

Traffic tunnel for end to end low latency

A system and method of creating more than one communication interface between a wireless device using a single, dual-radio transceiver by leveraging the basic service set (BSS) and radio measurement information. A wireless device operating in multiple-in, multiple-put (MIMO) mode maintains a first communications interface with an access point while establishing a second communications interface by downgrading the existing MIMO connection to a single-in, single-out (SISO) connection. The downgrading of the MIMO connection to a SISO connection frees up a radio signal processing chain to establish a second communications interface utilizing the BSS and radio measurement information from the first communications interface.

Supporting simultaneous communication interfaces

Systems and methods are described for reducing latency and improving beacon reception by a device capable of providing multiple wireless interfaces via a single radio (a 'multi-interface device'). The multi-interface device utilizes the single radio to communicate with a first device over a first wireless channel and to communicate with a second device over a second wireless channel. The multi-interface device determines that a difference in time between a transmission of a first beacon by the first device over the first wireless channel and a transmission of a second beacon by the second device over the second wireless channel is less than a predetermined amount of time. In response to determining that the difference in time is less than the predetermined amount of time, the multi-interface device sends a request to either the first or the second device to shift the transmission of future beacons by a requested offset time.

Systems and methods for reduced latency and improved beacon reception in devices capable of providing multiple wireless interfaces via a single radio

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.
