Abstract: A method for transmitting a signal in a wireless communications network includes calculating, by a network element, first and second average powers. The first average power is associated with a first time period of a downlink transmission between a transmitter associated with the network element and at least one user, and the second average power is associated with a second time period of the downlink transmission. The method includes transmitting, by the transmitter, the signal at one of a rated transmission power and a boosted transmission power based on a first threshold value associated with the first average power and a second threshold value associated with the second average power. The rated transmission power is less than or equal to a long-term average power limit associated with a power amplifier of the transmitter, and the boosted transmission is greater than the rated power.

Abstract: A wireless communication device includes more than one radio. A lossless switching module allows for selectively using one of the radios in a standby mode. The switching module allows for switching in the standby radio in the event that another radio fails without introducing any loss. In disclosed examples, switching module inputs coupled with inactive or failed radio output ports are coupled to an impedance corresponding to the associated radio. Disclosed examples are also useful for combining the outputs of more than one radio under selected circumstances.

Abstract: Locating mobile stations used for wireless communications even when the mobile station is within a building includes determining whether at least one indicator associated with a signal used by the mobile station identifies a single, known building location. Example types of indicators include a base station and sector identifier of a base station sector dedicated to a particular building, a delay associated with a radio frequency signal used by the mobile station when communicating from a particular building location or a combination of cell codes reported by a mobile station when it is within a particular building location. One or more of such indicators provides an indication of a building location from which the mobile station has placed a call. That building location can then be used as the determined mobile station location.

Abstract: In a method for generating pilot beacons for hard handoff over a border from a first environment to a second environment, the two environments using spread spectrum technology, a RF pilot signal may be received at an operational frequency used in at least the second environment. The RF signal may be downconverted to an IF pilot signal, filtered and then upconverted to a first reproduced RF pilot signal. The first reproduced RF pilot signal may be at a operational frequency used in a first environment, and may represent a pilot beacon for hard handoff between the first and second environments. The method and arrangement may be configured to receive a pilot beacon from one environment and to generate N pilot beacons, in that one environment, for up to N different operational frequencies used in another environment from which a mobile user is transiting, for hard handoff between the environments.

Abstract: An exemplary base station device includes a plurality of antennas configured to serve a plurality of sectors. A plurality of radios are coupled with the antennas for processing signals communicated on the antennas. One of the radios is coupled with at least one antenna that serves one of the sectors. The same radio is coupled with an antenna in a different one of the sectors. Another radio is coupled with a different one of the antennas in the one sector and at least one other antenna in a different sector. Such an arrangement of radios and antennas provides for at least simplex communication within each sector even if one of the radios fails.

Abstract: The input (and output) power of a multi-carrier amplifier can be controlled to allow the amplifier to operate at high RF power levels and still remain within a power rating profile. The amplifier (or amplifiers) power is controlled using an aggregate scaling factor. The aggregate scaling factor is generated from a plurality of amplifier scaling factors. Each amplifier scaling factor is generated based on a comparison of a time-averaged total power and a corresponding threshold.

Abstract: A method of increasing a number of possible users in a wireless communication system comprises directing steered beams to users within a sector of the system so that each user receives data via its own unique steered beam from a base station. The steered beams prevent more than one user from receiving data carried on the same beam. If the steered beams for at least two users are far enough apart so they do not interfere with each other, the base station assigns the two users the same code, such as the same Walsh code, for coding and decoding purposes to allow the base station to assign the same code to more than one user in a given sector.

Abstract: A processor monitors the real time forward link power utilization in a base station, and a controller regulates the real time forward link power utilization in the base station. The processor and controller operate in a feedback configuration to maintain call quality and prevent damage to the base station. The processor determines real time forward link power utilization on a per frame basis by taking samples at a per chip rate within each frame. The forward link power is then obtained by taking the mean of the samples.

Abstract: A transmitter including a continuous phase FSK modulator is disclosed for use primarily in optical transmission. The output frequencies are achieved by switching a capacitor into and out of an oscillator circuit by means of a PIN diode switch network which is responsive to a binary data input. The resulting sinusoidal waveforms are squared up by means of an inverte with feedback control for adjusting the duty cycle.
