| 20080242313 | LOW DUTY CYCLE DEVICE PROTOCOL - The subject matter disclosed herein relates to a system and method for establishing communication between a low duty cycle device and other devices through a wireless communication network. In one particular implementation, the low duty cycle device may awaken from a hibernating state in synchronization with transmission of messages. | 10-02-2008 |
| 20100015916 | NETWORK SERVER HAVING AN INFORMATION AND SCHEDULING CONTROLLER TO SUPPORT ONE OR MORE LOW DUTY CYCLE WIRELESS DEVICES - A network server, such as, for example, a mobile positioning center, having an information or schedule controller or having access to an information or schedule controller is provided. The information or schedule controller is provided with a schedule for a low duty cycle wireless device to provide the network server with the ability to store messages for transmission to the low duty cycle wireless device when the low duty cycle wireless device is in a low power mode of operation and transmit the messages during scheduled awake times. | 01-21-2010 |
| 20100017126 | METHOD FOR DYNAMIC CREATION OF A GEOFENCE IN A WIRELESS SYSTEM - A method and apparatus for creating a dynamic GeoFence area by determining an instant reference point using a first set of pseudorange measurements received by a GeoFence device, defining the dynamic GeoFence area referenced to the instant reference point, determining a position fix using a second set of pseudorange measurements, and comparing the position fix to the dynamic GeoFence area. In one aspect, an alert message based on the comparison results is presented to a user. | 01-21-2010 |
| 20100248642 | Gated RF Control Channel Demodulation Methods and Apparatuses - Methods and apparatuses are provided for use in devices that are enabled to receive control channel information over a link having a plurality of interlaced slots. The methods and apparatuses may be implemented to selectively disable/enable one or more circuits within a receiver path at selected times. | 09-30-2010 |
| 20100260150 | METHODS AND APPARATUSES FOR PROVIDING PEER-TO-PEER POSITIONING IN WIRELESS NETWORKS - Methods and apparatus are provided for use in wireless networks to provide and/or otherwise support peer-to-peer positioning operations. | 10-14-2010 |
| 20110080935 | Channel Hopping Based Content Protection Having An Out-Of-Band Communication Band - One feature provides a method for transmitting content to a receiving device, by establishing channel hopping sequence information with the receiving device via a first communication band. The channel hopping sequence information is associated with a plurality of traffic channels within a second communication band. Moreover, the method entails transmitting the content to the receiving device through the plurality of traffic channels via the second communication band using a channel hopping scheme implemented according to the channel hopping sequence information. In one embodiment, establishing the channel hopping sequence information with the receiving device via the first communication band further includes: obtaining a channel hopping sequence key; and transmitting the channel hopping sequence key to the receiving device within the first communication band. | 04-07-2011 |
| 20110164186 | DISTINGUISHING AND COMMUNICATING BETWEEN WHITE SPACE DEVICES TRANSMITTING ATSC-COMPATIBLE SIGNALS - White space signals are differentiated from licensed ATSC signals through modification of a waveform of the white space signal. White space signals may be modified by shifting the ATSC-compatible waveform so that the pilot frequency of the white space signal is at a location outside of the frequency range associated with the pilot frequency in a licensed ATSC signal or embedding a watermark signal into said ATSC-like white space signals. White space device transmitters generate the signals with these modifications and white space receivers are equipped to detect whether a pilot exists in the standard licensed pilot frequencies. Based on these differences, white space devices can better operate without interfering with licensed ATSC transmission. Additionally, the modification techniques may be used to embed data in the white space signal that may be used to communicate connection data or networking data to other white space devices. | 07-07-2011 |
| 20110170463 | METHOD AND SYSTEM FOR REAL-TIME CALIBRATION AND REPORTING OF PROCESSING DELAY - The subject matter disclosed herein relates to a system and method for estimating transmit chain and receive chain processing delays by a first wireless device. | 07-14-2011 |
