    摘要: A system and method are provided for providing precise location sensing for wireless devices in an indoor environment using channel fading fingerprinting. An indoor environment within which wireless devices are used is surveyed to develop a channel fading database for the indoor environment. The surveying of the indoor environment determines a specific channel fading profile according to 30 subcarrier frequencies in a wireless signal for numerous locations within the indoor environment. A wireless device scans for available wireless access points and extracts a channel fading profile for a current location of the wireless device. The extracted channel fading profile for the current location of the wireless device is compared with the channel fading database. A best match comparison between the extracted channel fading profile and the channel fading database is used to determine an actual physical location of the wireless device in the indoor environment.

    摘要: A method for coexistence radio communication systems is presented. In one embodiment, the method includes receiving a realtime frame synchronization signal and receiving one or more frame parameters. The method further includes determining, based at least on the frame synchronization signal and the frame parameters, estimated frame timing information and scheduling transmission based on the estimated frame timing information to avoid collision of the transmission and reception.

    摘要: Embodiments of systems and methods for Bluetooth and WiMAX coexistence are generally described herein. Other embodiments may be described and claimed. In some embodiments systems and methods are described to determine a temporal reference associated a frame, and then align another wireless frame with that temporal reference. Once aligned, transmissions and receptions in one wireless frame may be arranged to not temporally overlap with transmissions or reception the other wireless frame.

    摘要: Embodiments of a multi-radio wireless communication device having a Worldwide Interoperability for Microwave Access (WiMax) radio module and a Bluetooth (BT) radio module and methods for communicating are generally described herein. Other embodiments may be described and claimed. In some embodiments, a WiMax active signal is asserted by a coexist controller of the WiMax radio module during receipt of a downlink subframe, and the BT radio module aligns a BT slot boundary of either master-to-slave or slave-to-master slot based on timing information conveyed by the WiMax active signal. The WiMax active signal may be de-asserted by the coexist controller during transmission of an uplink subframe by the WiMax radio module.

    摘要: Embodiments of a multi-radio wireless communication device having two or more radio modules are generally described herein. In some embodiments, an initiating link manager may generate and transmit messages to a responding link manager. The messages may include a desired slot offset value and a desired point in time to perform slot adjustment. The responding link manager may return with a message indicating acceptance or nonacceptance of the desired slot offset value. If the responding link manager accepts the desired slot offset value, the message may also include whether the slot adjustment may be implemented at the desired point in time or incrementally. Other embodiments may be described and claimed.

    摘要: A magnetic resonance technology is used to implement front and back proximity sensing capability for wireless devices such as a laptap device. For example, a high quality (Q) factor coil antenna may be embedded in a display, such as a liquid crystal display, of a first laptap device to detect other wireless devices (e.g., a second laptap) that are within coupling distance of the first laptap device. In this example, the second laptap device induces a sine wave signal to the first laptap device if the second laptap device is physically located at backside of the first laptap device. Otherwise, the second laptap device may induce a cosine wave signal to the first laptap device if the second laptap device is physically located at the front side of the first laptap device.
