  • Publication number: 20150242358
    Abstract: A method and system for communicating data between two devices are described herein. The method detects an electrical signal of a first protocol from a first device in a repeater, wherein the first protocol comprises single-ended signaling. The method also determines the speed of the electrical signal. Additionally, the method converts the electrical signal of the first protocol into an electrical signal of a second protocol based on the speed of the electrical signal. The second protocol comprises differential signaling. Furthermore, the method sends the electrical signal of the second protocol to a second device. In addition, the method stops the electrical signal of the second protocol to the second device when the electrical signal of the second protocol indicates an end of data flow.

  • Publication number: 20140146716
    Abstract: Embodiments of a multi-transceiver wireless communication device and methods for adaptive multi-band communication are generally described herein. In some embodiments, the multi-transceiver wireless communication device is configurable for half-duplex operation and for asymmetrical full-duplex operation on two non-interfering channels. In some embodiments, a contention-based channel access procedure may be performed to attempt to gain access to both a primary channel and an auxiliary channel. A primary transceiver and an auxiliary transceiver may be configured for asymmetrical full-duplex operation when access to both the primary channel and the auxiliary channel is granted. One of the transceivers may be configured for half-duplex operation when access to only one of the channels is granted.
