A wireless network device including, in the wireless network device, a Bluetooth device and a wireless local area network device. The Bluetooth device is configured to establish a network of Bluetooth client stations and output a synchronization signal prior to a start of Bluetooth data transmission between the Bluetooth device and the Bluetooth client stations. The synchronization signal indicates the start of the Bluetooth data transmission. The wireless local area network device is configured to establish a network of wireless local area network client stations, receive the synchronization signal from the Bluetooth device, and transmit, a predetermined time subsequent to receiving the synchronization signal, a beacon to the wireless local area network client stations. The beacon instructs the wireless local area network client stations when to begin wireless local area network data transmission.

Systems and methods for bluetooth and WLAN traffic synchronization in a same wireless network device

A system including a physical layer module and a control module. The physical layer module is configured to generate a first clear channel assessment for a first sub-channel of a communication channel and generate a second clear channel assessment for a second sub-channel of the communication channel. The first clear channel assessment indicates whether the first sub-channel is free or busy. The second clear channel assessment indicates whether the second sub-channel is free or busy. The control module is configured to, in response to the second sub-channel being busy, extend a duration of the second clear channel assessment by a predetermined period of time, and transmit data via (i) only the first sub-channel or (ii) both the first sub-channel and the second sub-channel based on (a) the first clear channel assessment, (b) the second clear channel assessment, and (c) the extended duration of the first clear channel assessment.

Opportunistic 40 MHz mode of transmission in wireless transmitters

A wireless network device comprises a first wireless communication device that includes a first radio frequency (RF) transceiver that generates a synchronization pulse and that transmits and receives data according to a first period. A second wireless communication device receives a signal indicative of the synchronization pulse and includes a second RF transceiver that transmits and receives data according to a second period. The second period is not equal to the first period and the second wireless communication device adjusts the second period according to the first period and the synchronization pulse.

Bluetooth coexistence timing synchronization

A system includes a signal processing module and a control module. The signal processing module receives a first clear channel assessment (CCA) signal for a first sub-channel of a communication channel, increases a pulse width of the first CCA signal by a predetermined period of time, and generates a second CCA signal. The control module receives the second CCA signal and a third CCA signal for a second sub-channel of the communication channel. The control module transmits data via one of the second sub-channel and the communication channel based on the second and third CCA signals.

A wireless network device includes N access point (AP) modules having N BSSID's, where N is an integer greater than 1. The wireless network device includes a control module that communicates with the N AP modules. The control module stores the N BSSID's, a BSSID of an (N+1)external AP that communicates with M client stations, and at least one MAC address of at least one of the M client stations, where M is an integer greater than or equal to 1. The control module communicates with the (N+1)external AP by emulating at least one of the M client stations.

Network device for implementing multiple access points and multiple client stations

A network appliance includes a first media access controller with a first transmit queue storing one or more data packets to be transmitted to a first wireless device. A second media access controller includes a second transmit queue storing one or more data packets to be transmitted to a second wireless device. A baseband processor communicates with the first and the second media access controllers. An arbitration module arbitrates access of the first and second media access controllers to the baseband processor based on whether the first and second transmit queues have data packets to be transmitted to the first and second wireless devices, respectively. When both have data packets to be transmitted, the arbitration module instructs the first or second media access controller to flush any data packets stored in the first or second transmit queue so that transmission of a flushed data packet can be re-tried.

Dual MAC arbitration

A wireless network device includes a first media access controller (MAC) that generates a first output signal, a second MAC that generates a second output signal, and a communication channel. The communication channel includes a baseband processor in communication with a radio frequency transmitter and selectively transmits one of the first output signal and the second output signal.

A wireless network device having active and inactive modes comprises a clock generating module that generates a first clock signal having a first clock rate. A voltage supply module generates a first voltage level and a second voltage level that is less than the first voltage level. A first digital module receives the first clock rate and the first voltage level during the active mode, receives the second voltage level during the inactive mode and does not receive the first clock signal during the inactive mode. A first analog module communicates with the voltage supply module and has reduced current consumption during the inactive mode.
