摘要： A single radio wireless communications device is contemplated in which the user equipment (UE) operates according to more than one radio access technology. The UE may operate preferentially according to a first radio access technology, and may switch to a different radio access technology at predetermined intervals to check for incoming calls. An error unit within the UE may provide frequency error estimates to a GPS unit during operation according to the first radio access technology based upon signals received in the first radio access technology, unless any time spent in the different radio access technology is longer that a predetermined duration. In response to the predetermined duration being met, the error unit may provide the frequency error estimation to the GPS unit based upon signals received in the different radio access technology.

摘要： Embodiments of a system and method for tile-based reduction of access point location information are described. Embodiments may reduce a set of network access points and respective locations to generate a reduced set. For instance, embodiments may include parsing a representation of a geographic region into multiple tiles. Embodiments may also include, for each sub-area or “bucket” of multiple buckets that make up a given tile, evaluating the set of network access points and respective locations to identify network access points residing in that bucket, and based on a ranking of the network access points in that bucket, eliminating at least some network access points of that sub-area from the reduced set. Embodiments may also include, for each sub-tile of multiple sub-tiles of the given tile, assigning within the reduced set a common location to multiple access points residing within different locations of that sub-tile.

摘要： A portable test chamber with an open top may serve as a field testing apparatus for wireless testing of electronic devices. A wireless device under test may be mounted within a cavity in the test chamber. The cavity may be surrounded by a dielectric lining of anechoic material. A layer of electromagnetic shielding such as metal foil may cover the outer surfaces of the dielectric lining. The chamber may have a box shape with a rectangular opening at its top. Satellite navigation system signals or other wireless signals may be received through the opening at the top of the test chamber during testing. The electromagnetic shielding may reduce the effects of multipath interference during field tests.

摘要： An electronic device may include sensitive circuitry such as radio-frequency receiver circuitry. A noise source may produce radio-frequency interference that can disrupt operation of the sensitive circuitry. The noise source may include a first transmitter such as a cellular telephone transmitter and as second transmitter such as a wireless local area network transmitter. Interference may be produced by simultaneous operation of the first and second transmitters. The radio-frequency receiver circuitry may be satellite navigation system receiver circuitry that includes one or more satellite navigation receivers. The impact of interference may be reduced by blanking the satellite navigation system receiver, by imposing a duty cycle limitation on the second transmitter, by switching between alternative receivers in the satellite navigation system receiver circuitry, by using an interference-dependent cross-correlation protection scheme, or by using a combination of these schemes.
