  • Patent number: 9178539
    Abstract: Methods and apparatus for reducing transmit emissions are described herein. The transmit out of band emissions in an adjacent band can be reduced while complying with existing wireless communication standards through utilization of one or more of reduced transmit bandwidth, transmit operating band offset, and channel index remapping. The transceiver can support a receive operating band substantially adjacent to a band edge. The transmit operating band can be offset from an adjacent frequency band, and can use a narrower operating band than is supported by the receiver. The transmit baseband signal can have a reduced bandwidth to reduce the amount of noise. The frequency offset can introduce a larger transition band between the transmit operating band edges and the adjacent frequency band of interest. The transceiver can remap channel assignments to compensate for the frequency offset such that the frequency offset introduced in the transmitter is transparent to channel allocation.

  • Patent number: 7672690
    Abstract: Apparatus, and an associated method, by which to facilitate selection of with which network portion of a WLAN-cdma2000, or other multi-network radio communication system, that the mobile node should communicate. A parameter message is communicated to the mobile node. The parameter message includes indications, values of which are extracted from the message, buffered at a buffer, and subsequently accessed. A selector utilizes the accessed values to determine with which of the network portions that the mobile node shall communicate.

  • Patent number: 5822691
    Abstract: A system to detect the use of stolen mobile identification number (MIN) and electronic serial number (ESN) information to fraudulently place wireless calls by comparing the last phone number connected (LNC) as recorded by the radio telephone network with the last phone number connected as recorded in the mobile radio telephone unit. The mobile radio telephone unit LNC is transmitted to the base station upon initiation of a radio telephone call for comparison with the LNC recorded by the radio telephone network. The network will detect if a MIN/ESN combination is in use by two different mobile units because the LNC of the two mobile units will be different due to the different phone numbers called by each user.
