Abstract:
Selon l'invention, au niveau d'un dispositif de communication, un paquet reçu par l'intermédiaire d'un moyen de communication est traité. Pendant que le paquet est traité, de l'énergie fournie à au moins un composant dans le dispositif de communication est réduite, en réponse à la satisfaction d'une condition associée au traitement du paquet. L'énergie fournie au ou aux composants est restaurée avant la réception de la totalité du paquet au niveau du dispositif de communication.
Abstract:
At a communication device, a packet received via a communication media is processed. While the packet is being processed, power to at least one component in the communication device is reduced, in response to a condition associated with the processing of the packet being satisfied. Power to the at least one component is restored prior to receiving an entirety of the packet at the communication device.

Abstract:
This disclosure includes systems and methods for determining the location of each of a plurality of STAs of a WLAN where an AP measures the round-trip time (RTT) and the angle of arrival (AOA) to each STA from implicit packet exchange, such as data frame and ACK frame. The AP may then report the RTT and AOA measurements to each STA using a dedicated beacon information element (IE) which multicasts RTT and AOA measurements to the STAs. By employing an additional parameter, namely, angle of arrival AOA, a single AP may compute the two-dimensional location of each associated STA. Further, another beacon IE may multicast mapping of the AIDs to MAC addresses so that the associated STAs can understand such mapping for STAs in a network so that one STA may know the location of other STAs. Encryption may be employed to achieve privacy.
Abstract:
A method and apparatus for broadcasting short interframe space information to aid in determining a round trip time are provided. The round trip time is used as an aid in locating nodes within a WiFi or WLAN network. The method begins with capturing a time of transmission of a frame by a transmitting station. The receiving station then captures the time of arrival of the frame just sent by the transmitting station. The receiving station replies with a received frame message and the time of departure is captured. The transmitting station then captures the time of arrival of the received frame message. The captured arrival and departure times of the frame and the received frame message allow the round trip time to be computed. The RTT may then be included as part of a network message.
