Interference can be modeled prior to deployment and/or at deployment using a series of test signals transmitted by one transceiver while the corresponding interference is monitored on a second transceiver.

Abstract: A distributed multiband antenna intended for radio devices, and methods for designing manufacturing the same. In one embodiment, a planar inverted-F antenna (PIFA) configured to operate in a high-frequency band, and a matched monopole configured to operate in a low-frequency band, are used within a handheld mobile device (e.g., cellular telephone). The two antennas are placed on substantially opposing regions of the portable device. The use of a separate low-frequency antenna element facilitates frequency-specific antenna matching, and therefore improves the overall performance of the multiband antenna. The use of high-band PIFA reduces antenna volume, and enables a smaller device housing structure while also reducing signal losses in the high frequency band. These attributes also advantageously facilitate compliance with specific absorption rate (SAR) tests; e.g., in the immediate proximity of hand and head “phantoms” as mandated under CTIA regulations.

Abstract: In one embodiment the present invention includes an RFID gaming token with a ferrite core. When the RFID gaming tokens are stacked, the ferrite cores steer the flux field from the excitation antenna through the center of the annular antennas in each token.

This increased efficiency also improves the data transfer to and from the passive tags. This increased efficiency allows for reading RFID gaming tokens at a higher stack height (or at a better error rate for a given stack height) as compared to existing air core gaming tokens.
