Abstract: A method of managing the number of base station engaged in soft hand-off in a mobile communication system (fig. 3). The method involves manipulating a subscriber (200) based directional antenna (120) so as to control the number of base transceiver stations (130), pilot channels, beacon signals or other signals detected to be used in soft hand-off processing. The adaptive antennas (220) are modified to manage the number of active set members, such as by manipulating direction, beamwidth, or other antenna parameters.

Abstract: A technique for allowing a first and second group of users to share access to a communication channel such as a wireless radio channel is disclosed. The first group of users can be a group of legacy users such as those that use digital CDMA cellular telephone equipment based on the IS-95 standard. The second group of users can be a group of web surfers that code their transmissions using one of multiple formats. The first group of users can share one modulation structure such as, on a reverse link, using unique phase offsets of a common pseudorandom noise (PN) code. The second group of users can share another modulation structure, but in a manner that is consistent and compatible with the users of the first group. Specifically, the users of the second group may all use the same PN code and code phase offset. Each channel used by the second group of users can be uniquely identified by a corresponding unique orthogonal code.

Abstract: A repeater for a wireless network in which a signal radiation path provided by building wiring is used to provide spatial separation between at least two radiating points. The repeater is preferably packaged into a housing that is suitable for use in an Alternating Current-to-Direct Current (AC/DC) transformer (or wall wart). If the radiating point includes at least one antenna, the antenna may also be incorporated within the transformer housing. The radiating points can be provided by at least two antennas, in which case the building wiring includes a coaxial cable, such for carrying video or cable signals. The building wiring may also be standard Alternating Current (AC) three-wire conductor cable, which may or may not be placed within building walls. In this implementation, the radiating point is determined by a matching circuit. A frequency conversion circuit can cause the radiation from at least one radiating point to occur at a carrier frequency that is different from the carrier frequency of the other radiating point.

Abstract: In a reverse link of a wireless CDMA communication system, a method of maintaining an idling mode connection between a field unit and a base transceiver station is provided using various techniques to maintain the idle mode connection at a reduced power level. A preferred embodiment computes a time slot or frame offset based on modulo function using a field unit identifier in order to distribute field unit maintenance transmissions among available slots or offsets. An alternate embodiment detects explicit signaling states changes at the physical layer and causes power target changes. A further embodiment transmits maintenance data during predetermined time intervals, coordinated between the field units and BTS, allowing power levels to be adjusted accordingly.

Abstract: An adaptive antenna signal identification process to provide increased interference rejection in a wireless data network such as a wireless Local Area Network CLAN), The adaptive antenna is located at an access point and can be steered to various angle of arrival orientations with respect to received signals. Associated radio receiving equipment utilizes two distinct signal detection modes. In a first mode, the directional antenna array is set to have an omni-directional gain pattern. In this mode, certain identification parameters of an initial portion of a received signal are detected, such as a source identifier. If the received signal has not been previously detected, then the antenna array is scanned determine a direction setting that provides a best received signal metric. Once the best directional setting for the received signal, that setting is saved for future use in receiving the same signal. If the received signal has been previously detected, the system instead will steer the directional antenna to the last known best direction for reception for the particular detected signal. As further portions of the same signal are received, such as payload portions of a data frame, the directional antenna array can continue to scan potential new best angles. When the invention is deployed in a relay function, where messages received from a first node are to be forwarded to a second node, the recorded direction of its best reception is retrieved for the second node and used when the antenna array is used to transmit the signal to the second node. Storage of the best antenna angle for propagation to neighbor nodes can be handled by control functions in a manner that is analogous to other router lookup tables, such as being contained in a lookup table that stores IP addresses.

Abstract: A repeater (100) that extends the range of a wireless communication system (120) especially one using Time Division Duplex (TDD) protocols. The device preferably translates signals (120) received on a first radio frequency channel to a second radio frequency channel. The repeater preferably monitors one or more channels for transmissions. When a transmission on one channel is detected, the repeater is configured to translate the received signal to another channel where it is then transmitted. The device thus solves a problem of isolating input and output signal from one another.

Abstract: A system (115) causes a scan angle of a directional antenna (110) to change temporarily from a current scan angle to at least one trial scan angle during reception of predetermined portions of an information carrying signal. At the trial scan angle(s), a trial metric associated with each trial scan angle (125) is determined by the system (115). The system (115) then selects a next scan angle based on the trial metrics. Examples of predetermined portions of the information carrying signal include the Power Control Bit (PCB) and certain symbol periods of the Forward Error Correction (FEC) block.
