摘要： A method is provided for operating a wireless local device. In this method a local device receives a beacon for a current superframe in a common signal format. The beacon includes time slot assignment information. The local device then determines a device format for the transmission of data to a remote device based on format determination information. The device format can be one of a common signal format, and one or more wireless formats. The local device then determines one or more remote device time slots in the superframe assigned for transmission of the data to the remote device based on the time slot assignment information. Finally, the local device transmits the data in the one or more remote device time slots to the remote device using the device format.

摘要： A method is provided for transmitting data. A first device generates a first signal having a first duty cycle, comprising a first gated-on portion and a first gated-off portion in a time slot; and a second device generates a second signal having second duty cycle, comprising a second gated-on portion and a second gated-off portion in the same time slot. The first gated-on portion is generated during a first segment of the time slot and the first gated-off portion is generated during a second segment of the time slot, while the second gated-on portion is generated during the second segment and the second gated-off portion is generated during the first segment. Media access control (MAC) can be used to further define positions within time slots and provide error correction, power control, and the like. A preamble can be transmitted at an increased power level to facilitate acquisition.

摘要： A system and method are provided for authenticating a new device in a wireless network using an authentication device. First, the new device estimates the distance between the new device and the authenticating device as a first distance measurement, and sends the first distance measurement to the authentication device. The authentication device then estimates the distance between the new device and the authenticating device as a second distance measurement. The authentication device then evaluates the first and second distance measurements to determine if they meet authentication criteria and sends authentication data to the new device only if the first and second distance measurements meet the authentication criteria. These criteria can be that they do not differ by more than a set error value or that they both are below a set maximum value.

摘要： A method is provided for receiving a data frame in an ultrawide bandwidth network. In this method, a device receives an ultrawide bandwidth signal containing a data frame. The device then performs an acquisition operation during a first preamble in the data frame, and identifies a marker after the first preamble that indicates that the first preamble has ended. After this, the device performs a signal processing operation during a second preamble in the data frame. After the training, the device then receives a header in the data frame, and then receives a payload in the data frame. By having a marker between the two preambles, this method provides a receiving device with critical information regarding the timing of the preamble section of a frame.
