    Abstract: Methods and systems for optimal frequency planning for an integrated communication system with multiple receivers may include adjusting a center frequency of a low IF signal to reduce interference by a second order interference signal. The center frequency may be adjusted to avoid high power portions of the second order interference signal. The interference level corresponding to a center frequency may be determined by, for example, a SNR of the low IF signal, or by determining a BER for the low IF signal. The center frequency of the low IF signal may be dynamically adjusted to keep second order interference level at an acceptable level. Adjusting the center frequency of the low IF signal may also comprise keeping the low IF signal from being blocked by a DC component of the second order interference signal.

    Abstract: A wireless communication device is provided with both a transceiver and a low-cost RFID reader. The RFID reader is operable to generate a first outbound radio frequency (RF) signal from first outbound data, to receive a first inbound RF signal responsive to the outbound RF signal and to convert the first inbound RF signal into inbound RFID digital data. The transceiver is operable to generate a second outbound radio frequency (RF) signal, to receive a second inbound RF signal and to convert the second inbound RF signal into inbound transceiver data.

    Abstract: A multi-standard single chip integrated within a multi-standard mobile device concurrently receives multi-standard radio frequency signals by corresponding two or more integrated radios. The multi-standard single chip generates full GNSS measurement comprising pseudo-range information using the received radio frequency signals. The multi-standard single chip comprises a GNSS radio and multiple non-GNSS radios such as Bluetooth. The full GNSS measurement is generated using GNSS radio frequency signals received by the integrated GNSS radio and communicated over, for example, Bluetooth radio. GNSS satellite reference information embedded in radio frequency signals received by the integrated non-GNSS radios is extracted to assist the full GNSS measurement. A full GNSS navigation solution for the multi-standard mobile device is generated internally to and/or externally to the multi-standard single chip depending on the location of a navigation engine. The generation of the full GNSS measurement is independent of a host processor within the multi-standard mobile device.
