Abstract: Angle of arrival and/or range estimation within a wireless communication device. Appropriate processing of communications received by a wireless communication device is performed to determine the angle of arrival of the communication (e.g., with respect to some coordinate basis of the wireless communication device). Also, appropriate processing of the communications may be performed in accordance with range estimation as performed by the wireless communication device to determine the distance between the transmitting and receiving wireless communication devices. There are two separate modes of packet processing operations that may be performed: (1) when contents of the received packet are known, and (2) when contents of the received packet are unknown. The wireless communication device includes a number of antenna, and a switching mechanism switches from among the various antennae capitalizing on the spatial diversity of the antennae to generate a multi-antenna signal.

Abstract: Certain embodiments of the invention may be found in a method and system for antenna and radio front-end topologies for a system-on-a-chip (SOC) device that combines Bluetooth and IEEE 802.11 b/g WLAN technologies. A single chip radio device that supports WLAN and Bluetooth technologies receives a WLAN signal in a WLAN processing circuitry of the radio front-end and in a Bluetooth processing circuitry of the radio front-end. Signals generated by the WLAN processing circuitry and the Bluetooth processing circuitry from the received WLAN signal may be combined in a diversity combiner that utilizes selection diversity gain combining or maximal ratio combining (MRC). When a generated signal is below a threshold value, the signal may be dropped from the combining operation. A single antenna usage model may be utilized with the single chip radio device front-end topology to support WLAN and Bluetooth communications.

Abstract: Hybrid location determination for wireless communication device. Various services that may be used by a wireless communication device within a particular location may be referred to as location based services (LBS). As such, means by which the location of a wireless communication device that may use such available services, within such a locale, is made by using more than one type of location determination approach.

Abstract: A communication device includes a first and second near-field wireless (NFW) module operating with a first and second protocol, respectively. A module and method to improve the operational efficiency of the first and second NFW modules are disclosed. Due to close proximity between the first and second NFW modules in the communication device, an undesirable parasitic inductive coupling can occur that can degrade the operational performance of the modules. The first NFW module can be configured to control inductive coupling of the second NFW module when an electromagnetic (EM) field operating with the first protocol is detected. Additionally, the second NFW module can be configured to control inductive coupling of the first NFW module when an EM field operating with the second protocol is detected. Controlling the inductive coupling of each module can be performed by means of detuning an inductive coupling element of each module.

Abstract: Methods and systems for enabling coexistence of multiple potentially interfering wireless components in a device are provided. A device may include a wireless module using a proprietary protocol and one or more modules using standardized protocols. The device further includes a coexistence arbitration module configured to arbitrate access to a shared communication medium among the wireless modules based on assertion of medium access requests by the modules and the associated priority of the asserted medium access requests. When multiple medium access requests have the same priority, precedence for access to the shared medium is determined based on additional criteria. The coexistence arbitration module may be a separate module or may be integrated into another module or distributed among the modules. The device may include a host processor for altering transmission characteristics of a module to increase the likelihood that another module can receive data within a reasonable time period.
