摘要： A method of operating a wireless network includes sending a pattern of wakeup tones. Each of the wakeup tones has a different frequency. A sleep mode is periodically awoken from to listen for the wakeup tones. The pattern of wakeup tones is received during the listening. It is decided whether to listen for at least one second tone. The deciding is dependent upon the received pattern of wakeup tones.

摘要： A data encryption method includes providing a sender node having information to transmit. The information is divided into a sequence of frames. A respective one of a plurality of frame numbers is assigned to each of the frames. At least one nonce and at least one security key are used to perform block cipher encryption and produce within the sender node a respective block cipher encryption output for each of the frames. The information is converted from a sequence of plaintext frames to a sequence of ciphertext frames by use of the block cipher encryption outputs produced within the sender node. The converting is performed within the sender node and after the block cipher encryption outputs have been produced within the sender node. A receiver node is used to ascertain the frame numbers. The at least one nonce is transmitted from the sender node to the receiver node. The at least one nonce and the at least one security key are used to perform block cipher encryption and produce within the receiver node a respective block cipher encryption output for each of the frames. The ciphertext frames are transmitted from the sender node to the receiver node. The ciphertext frames are transmitted after the block cipher encryption outputs have been produced within the receiver node. The transmitted ciphertext is converted back into the plaintext frames by use of the block cipher encryption outputs produced within the receiver node. The converting is performed within the receiver node and after the block cipher encryption outputs have been produced within the receiver node.

摘要： A method of synchronizing wireless devices includes establishing a recurring sequence of frequency channels at which the wireless devices are to communicate. The frequency channels are divided into a plurality of groups. Synchronization information is transmitted at a respective first frequency channel in each of the groups of frequency channels during a first sampling time period. One of the groups of frequency channels is selected. A wireless device is used to sample each of the frequency channels in the selected group during the first sampling time period. Non-synchronization information is transmitted after the first sampling time period. Synchronization information is transmitted at a next respective frequency channel in each of the groups of frequency channels during a next sampling time period. The next sampling time period occurs after the transmitting of the non-synchronization information.

摘要： A data communication method includes providing a sender node having a data packet of information. The data packet includes at least one first field and a second field. The second field has content that is dependent upon actual content of the at least one first field. The content of the second field of the data packet is transmitted from the sender node to a receiver node. The receiver node is used to predict the actual content of the first field of the data packet. The receiver node is used to calculate the content of the second field of the data packet based upon the predicted content of the first field. The predicted content of the first field is confirmed to be equivalent to the actual content of the first field. The confirming step includes comparing the calculated content of the second field to the transmitted content of the second field.

摘要： In a wireless transmission system, a transmitter sends a plurality of data packets to a receiver. The transmitter identifies channel quality indicators corresponding to properties of a communication channel between the transmitter and the receiver. During operation, the transmitter adjusts one or more parameters that affect the Quality of Service (QoS) of data transmission between the transmitter and receiver to enable data transmission at different quality levels over a range of channel quality levels. In one embodiment, the transmitter sends data packets corresponding to video from a camera to the receiver.
