Abstract: In a wireless local area network, a first and second access point in which the RF coverage areas overlap are synchronized by positioning a monitor station within the overlap area. The monitor station receives beacon frames from both access points and records the arrival times. A manager in communication with both access points and the monitor station calculates a retardation interval and issues a control command to the second access point to retard transmission of its beacon frame. The retardation interval is calculated such that the contention-free period of the second access point does not overlap the contention-free period of the first access point. The manager may also issue control commands to the first and second access points to adjust their contention-free periods.

Abstract: A method of transmitting universal serial bus (USB) frames over a communications channel is disclosed. A USB device receives one or more USB frames from a host device via a network, wherein the one or more USB frames are encapsulated in one or more data packets based on a communications protocol associated with the network. The USB device further synchronizes a local clock signal with a clock signal of the host device using a clock synchronization mechanism of the communications protocol. The USB device then determines a number of USB frames transmitted by the host device and processes the one or more USB frames based, at least in part, on the synchronized local clock signal. For some embodiments, the USB device may receive a frame count value and a corresponding media time value from the host device.

Abstract: In a communication system comprising one master device and one or more slave devices, the slave devices synchronize to a common timebase maintained at the master device, independently of a wireless module timebase, without requiring transmission of accurate and real time master timer information from the master device. In one approach, a slave device sends timing information to the master device, the timing information representing the slave device timebase, and the master device sends back correction information to the slave device, the correction information representing a difference between the slave device timebase and the master device timebase, the correction information being usable independent of the timing of sending back the correction information. The master timebase might be a system master timer of an accurate timer based on a timer interrupt and a high resolution timer having a resolution greater than a timer interrupt resolution.

Abstract: A signal processor includes a period detection section which detects that a period is currently used for communication of a frame; a pattern detection section which detects, from the received signal, a first signal pattern by which the end of communication of the frame is recognized; and an output processing section which outputs the received signal to a controller, configured to instruct, upon detection of the first signal pattern in the period being currently used for communication of a frame, the controller to halt startup of communication action of the next frame, until the period being currently used for communication of a frame comes to the end, to thereby reduce an event such that frames are transmitted from a plurality of communication devices simultaneously, and to thereby allow the communication action for the next frame to proceed correctly.
