Abstract: Interference removal in spread spectrum signals, comprises the steps at a spread spectrum transmitter (10) of spreading information across a predetermined spectrum by phase modulating a repeating noise sequence (18), providing a spread spectrum signal and transmitting the spread spectrum signal. The method further comprises the steps at a receiver of receiving the spread spectrum signal along with interference (41) multiplying (42) the spread spectrum signal along with interference by a window function (44) providing a multiplied spread spectrum signal. The information is recovered by despreading the multiplied (48) spread spectrum signal using a reciprocal (50) of the spectrum of the repeating noise sequence to obtain a data spectrum with interference and subsequently normalize (52) to obtain a clean data spectrum. Alternatively the information can be recovered by substituting a corrupted magnitude spectrum with a prestored PN sequence magnitude spectrum (70) as shown by receiver (60).

Abstract: A wireless communications network (2) including a fixed master communication device (4) capable of initiating an action or requesting a service on the wireless communication network and a mobile slave communication device (6) to wirelessly communicate with the master communication device. The slave communication device (6) registers with the master communication device (4) to determine a location of the slave communication device and the slave communication device automatically downloads a location-specific portal corresponding to the location of the slave communication device from the master communication device (40-50). Further, communication controls of the slave communication device can be set according to the specific location by referring to a location distribution profile server (27) when the location of the device is determined (52-62).

Abstract: A wireless communication system conducts (402) communications between a fixed portion (102) of the wireless communication system and a portable subscriber unit (122) carried by a user; and records (404) a relevant aspect of the communications, thereby producing recorded information. The system determines (405) a current time of day and a current position of the user and makes (406) a comparison of the recorded information with the current time of day and the current position of the user to determine whether an alert is necessary, and generates (412) the alert when the comparison determines the alert is necessary.

Abstract: A portable subscriber unit (122) and a controller (112) cooperate to maintain (402) a table (226, 326) identifying operations that utilize location information, and corresponding resolutions preferred for the location information when performing ones of the operations. When a request to perform an operation is received (404), the portable subscriber unit and the controller cooperate to select (408) a resolution preferred for the operation, in response to the request; and then to determine (414) and report (418) the location information at the resolution preferred for the operation.

Abstract: A first transceiver (122) detects (402) a need for desired information available from a network server (108). In response to detecting the need and before contacting the network server, the first transceiver attempts (412) to obtain the desired information from another transceiver of a plurality of wireless transceivers near the first transceiver, thereby potentially eliminating a necessity for the first transceiver to contact the network server to obtain the desired information.

Abstract: A wireless communication system receives (402) a communication specifying a portable subscriber unit (122) for which the communication is intended, and further indicating an originator location at which an originator of the communication is positioned. The system determines (404) a recipient location at which the portable subscriber unit is positioned. The system then calculates (406) a distance between the originator location and the recipient location, and routes (412) the communication to the portable subscriber unit when the distance meets a distance criterion.

Abstract: A table (328) is created (402) for mapping, for ones of a plurality of portable subscriber units (122), a plurality of message types to a corresponding plurality of locations. A message matching one of the plurality of message types is then received (404) by a controller (112), the message intended for a portable subscriber unit. In response, the controller and the portable subscriber unit cooperate to determine (406) the location of the portable subscriber unit. The controller sends (428) the message to the portable subscriber unit when the location matches one of the plurality of locations corresponding to the one of the plurality of message types.
