摘要:
An apparatus and associated methods to provide precision ranging measurements in an ultrawideband (UWB) wireless communication system are generally described. In this regard, according to one example embodiment, an innovative ranging agent is introduced that effectively computes one or more of the time of signal propagation, the difference in local clocks and frequency offsets to calculate an increasingly accurate estimate of the proximal distance between two or more devices in UWB communication.

Briefly, in accordance with an embodiment of the invention, a method and apparatus to transfer information is provided, wherein the method includes transferring information between at least two wireless devices using a waveform that includes a first sinusoidal signal and a second sinusoidal signal, wherein the second sinusoidal signal has more zero-crossings than the first signal and wherein a duration of the first sinusoidal signal is less than a duration of the second sinusoidal signal.
摘要:
In some embodiments a transceiver includes a quadrature phase-shift keying modulator and/or demodulator to transmit and/or receive a frequency-hopping ultrawideband radio signal. Other embodiments are described and claimed.
摘要:
Arrangements for a reduced power consumption network device are disclosed. In one embodiment, the device can join the network by communicating with a second network compatible device. After the network connection is made the device can place communication configuration or network status processing components in a low power mode until the device detects an indication of a status change in a communication from the second device. When the status change is detected the device can activate the status processing components that were placed in the low power mode and these processing components can process the status change information to change a communication configuration. Significant power saving can be achieved by placing such components into the sleep mode.
摘要:
A wireless device incorporates decentralized spectrum management to dynamically control a power level for each channel in a transmission spectrum. The decentralized spectrum management uses a common reference signal received from a TV station to select a channel and coordinate the transmitter power to mitigate interference. The decentralized spectrum management ensures that the propagation loss between the desired and interfering transmitters exceeds a desired power ratio in order to facilitate frequency reuse on a non-interfering basis.
摘要:
An antenna system for providing network access services to wireless users generates at least a first and a second antenna beam, where the second antenna beam is movable with respect to the first. Additional antenna beams may also be generated. During installation of the antenna system, an installer may adjust the position of the second antenna beam (and possibly other antenna beams) in a manner that enhances the maximum data-rate coverage area of the antenna system for a given deployment region.
