Abstract: Assigning CDMA channel codes in a multiple beam zone sector such that they may be reused within the same sector. In an exemplary embodiment, the method includes configuring directional antennas in a cell sector to provide multiple beam zones in a cell sector and assigning channel codes for use within the beam zones such that each channel code is assigned for use in only one beam zone of any set of three consecutive beam zones in the cell sector. The reassignment is preferable conditioned upon the mobility status of the user. This effectively reduces the inter-user interference by ensuring at least two intervening beam zones are located between zones that are using the same channel codes, and that the second user is not mobile. The channel codes may be Walsh codes or quasi-orthogonal functions (QOFs).

Abstract: A method and system of selecting antennas and/or equipment for use within a wireless communication system is disclosed. A cell site may have one antenna-arrangement shared between multiple groups of radio equipment that are each operated by respective wireless service providers at the cell site. The cell site may also have a base station controller that may select from the shared antenna-arrangement an antenna for radiating signals from the groups of radio equipment. The base station controller may also select from the multiple groups of radio equipment a group of radio equipment for processing signals received at the shared antenna-arrangement.

Abstract: A method and system are disclosed for bypassing a cellular wireless communications system by using a peer-to-peer wireless link for voice communications between BLUETOOTH enabled handsets. In an exemplary embodiment, when a ten-digit telephone number is dialed to place a call from a cellular wireless telephone, the cellular wireless telephone determines whether a termination-point, such as a second cellular wireless telephone, associated with the ten-digit telephone number is within range of the peer-to-peer wireless link. If the termination-point is within range, then a direct intercom session may be established over the peer-to-peer wireless link. Otherwise, a call initiation is requested over the cellular wireless communications system.

Abstract: A method and system for diversity transmission from a mobile station. Signals sent from a mobile station to a base station may suffer from fading. To combat this, diversity transmission is used to compensate for the effects of fading and destructive multi-path interference by sending two or more signals. Signals to be transmitted from the mobile station are split into a first split signal and a second split signal and diversified from one another. Diversification of the split signals may be accomplished by modifying the phase of either the first split signal, the second split signal or both the first and second split signal. The diversified signals may then be transmitted from a first and second antenna.

Abstract: A wireless repeater for receiving, amplifying and transmitting one or more wireless signals. The repeater comprises a signal processing device for determining one or more attributes of a wireless signal received from a base transceiver station and a memory for storing a reference list that includes a list of one or more preferred frequency bandwidths to be received, amplified and transmitted. The repeater further comprises a controller coupled with the signal processing device for comparing the one or more attributes of the wireless signal from the base transceiver station with the reference list, where the controller selects a first active set of one or more frequency bandwidths from the preferred frequency bandwidths based on the comparison.

Abstract: A repeater for a wireless network might use a first communication interface to detect the presence of a wireless device. Alternatively, another network element might use the first communication interface to detect the presence of the wireless device and then provide a notification to the repeater. The first communication interface might be a low-power communication interface, such as one that uses Bluetooth. In response to detecting a wireless device or receiving a notification, the repeater might switch to an active mode and begin repeating signals on the wireless network via a second communication interface, such as one that uses CDMA.

Abstract: A method and apparatus for managing beam selection in a mobile station. The mobile station determines that, using a currently selected beam, the mobile station would have to transmit at too high of a power level in order to maintain a balance between a forward link path and a reverse link path. The mobile station computes a transmit power on the currently selected beam and compares the computed transmit power to a predefined threshold value. If the computed transmit power exceeds the predefined threshold value, the mobile station may switch to another beam. Otherwise, the mobile station will stay with the current beam, regardless of whether the current beam has the highest receive power.

Abstract: According to an embodiment, a distributed antenna system (DAS) is provided with functionality for determining the location of a mobile station within the DAS. The DAS may be of the type that includes a plurality of antennas located within a multi-floor building, each antenna radiating to define a respective coverage area in which the mobile station can communicate. The antennas are communicatively linked with a controller, and the controller communicates over an air interface with a radio access network so as to provide connectivity between the antennas and the radio access network. In operation, the system may determine that a given one of the antennas has received a strongest signal from the mobile station, and may transmit an indication of the geographic coverage area of the given antenna into the radio access network, as a representation of the location of the mobile station.

Abstract: A wireless repeater for receiving, amplifying and transmitting one or more wireless signals. The repeater comprises a signal processing device for determining one or more attributes of a wireless signal received from a mobile device and a memory for storing a reference list that includes one or more preferred frequency bandwidths to be repeated. The repeater also comprises a controller coupled with the signal processing device for comparing the one or more attributes of the wireless signal with the reference list, wherein the controller selects a first active set of one or more frequency bandwidths from the preferred frequency bandwidths based on the comparison. The repeater still further comprises a first reception filter coupled with the controller, where the first reception filter, responsive to control signal(s) from the controller, filters out signals, communicated to the first reception filter, having frequencies outside the first active set of frequency bandwidths.

Abstract: A method and system of communicating between a base station and a mobile station is disclosed. The base station may be the core of a cell site, which is defined by radio frequency radiation patterns. The cell site may be divided into a number of sectors, each defined respectively by radiation patterns. The mobile station, while within any of the sectors of the cell site, may communicate with the base station on a reverse link by encoding signals using a spreading sequence offset by a common time delay. On the forward link, each sector is assigned a respective time delay that is within the common time delay. While within a respective sector of the cell site, the mobile station may receive signals from the base station on the forward link that have been encoded with the spreading sequence offset by the sector's respective time delay.

Abstract: A method and system of wireless signal repeating. A wireless signal repeater may receive a group of signals and select signals to be amplified so as to produce amplified signals. The repeater may also select antenna elements to re-transmit the amplified signals. The repeater may further select areas to direct the elements' radiation patterns in order to provide extensive wireless service to desired areas. The repeater can perform any of these selection functions simultaneously and/or independently, and based on any desired criteria. For example, each signal received into the wireless signal repeater may carry an identifier. The repeater may perform the selection functions based at least in part on the identifiers of the signals.

Abstract: A method and system having one or more fractal antennas for communicating signals. The fractal antennas are coupled to a diversity receive circuit for receiving the signals. The diversity receive circuit provides an output signal based on a combination of the receive signals. The fractal antennas and the diversity receive circuit can help compensate for, or reduce the effects of fading. Additionally, a transmitter provides a transmit signal. One of the fractal antennas may both transmit and receive signals. Alternatively, a transmit antenna, separate from the receive antennas, may transmit the transmit signals. The fractal antennas may also be fractal arrays for providing additional resistance to fading.

A list of sectors of the system that require additional capacity may be compiled and a carrier frequency may be applied to a selected group of those sectors. The sectors may be selected based on a distance between each other and/or based on a probability of handoff from one another, for instance.
