摘要： Systems and methods for media access control (MAC) layer bridging of a real communication device to a simulated network are described herein. Some illustrative embodiments include a communication network bridge that includes a processor that executes simulation software that implements a simulated network and further implements a simulated network interface that provides a communication path to the simulated communication network, and a real network interface that provides a communication path to a real communication network. A first media access control (MAC) layer message that conforms to a protocol associated with the real communication network is received by the real network interface from across the real communication network. The first MAC layer message is transformed by a first transformation operation into a second MAC layer message that is forwarded to a physical (PHY) layer of the simulated network interface.

摘要： A system comprises radio circuitry, an access point (AP) feature, and a station (STA) feature. The AP feature causes the radio circuitry to transmit data to a hardware device during a beacon interval. The AP feature is not used to receive data from the hardware device during the beacon interval except to receive data request signals. The STA feature causes the radio circuitry to receive data from the hardware device during the beacon interval. The STA feature is not used to transmit data to the hardware device during the beacon interval except to transmit data request signals. The radio circuitry is in a de-powered state during the beacon interval when the radio circuitry does not transmit or receive data or data request signals.

摘要： Systems and methods for avoiding access point transmission rate fall-back mechanism having an avalanche effect when acknowledgements are not received for packets sent during co-existence of WLAN and other wireless network technologies. A receiver comprises at least two dissimilar network technology subsystems. In some embodiments, a transmitter transmits a handshake to the receiver prior to transmission of at least one data packet and does not reduce a transmission rate of future transmissions to the receiver if the transmitter does not receive a reply to the handshake. In other embodiments, the receiver is able to send an indicator to a transmitter requesting a protection mechanism be employed prior to transmission by the transmitter of at least one data packet. In further embodiments, the receiver is able to negotiate with the transmitter for the transmitter to employ a protection mechanism prior to transmission of at least one data packet to the receiver.

摘要： A system composed of a node configured to transmit a first data stream to a first device using a first protocol and a second data stream to a second device using a second protocol. The system is also composed of a controller in communication with the node. The controller is configured to prioritize a first packet of the first data stream prior to transmission of the first packet. The prioritization is based on application layer information of the first packet. If the application layer information of the first packet indicates that the priority of the first packet is lower than the priority of a second packet of the second data stream, the controller causes the node to transmit the second packet.
